ChatGPT answers, unedited

For a content partnership site where you expect lots of addresses such as partnerships@, authors@, media@, hello@, plus potentially arbitrary inbound addresses, I’d prioritize:

1. Catch-all support
2. Lots of aliases without paying for a mailbox for each
3. Ability to send from aliases
4. Good spam filtering
5. Multiple domains/subdomains if you launch additional sites
6. Solid deliverability/authentication (SPF, DKIM, DMARC)

My pick: Zoho Mail

zoho.com would be my first choice for your use case.

It explicitly supports both catch-all addresses and multiple aliases per mailbox. Zoho's documentation says aliases deliver into the same mailbox and can also be used as the From address when sending. Zoho Zoho

For example, you could have one actual mailbox:

you@site.com

with:

• partnerships@site.com
• collabs@site.com
• contributors@site.com
• media@site.com
• hello@site.com
• press@site.com

all going into that same mailbox. You can then use filters to sort messages based on which alias was addressed. Zoho

And the catch-all can capture addresses you haven't explicitly created—for example, someone emails jane@site.com even though you never created jane. Zoho supports configuring a catch-all account for precisely this situation. Zoho

How I'd structure your setup

I'd actually avoid creating dozens of individual mailboxes.

Something like:

Then use filters/folders to automatically separate partnership inquiries, contributor submissions, etc.

Zoho also supports multiple domains and domain aliases, which becomes useful if you eventually operate several content sites under the same organization. Zoho

Other options

Fastmail — excellent if you care primarily about having a polished, simple email experience. I'd consider it a strong alternative, but for a business/content operation where domain administration and organizational features matter, I'd lean Zoho.

Google Workspace — excellent overall, particularly if you'll heavily use Gmail/Docs/Drive, but you're paying for a more comprehensive productivity suite than you necessarily need just for email.

Cloudflare Email Routing — interesting if you mainly need forwarding/aliases, rather than a full hosted mailbox. I wouldn't make it my primary choice if you'll be doing substantial two-way email communication with partners.

Bottom line

For your particular use case: Zoho Mail.

The combination of catch-all + aliases + custom domains + domain aliasing + filters makes it unusually well suited to a content partnership site where you may not know all the addresses people will contact. Zoho Zoho

One caution: catch-all mailboxes can attract a lot of spam, so I would enable aggressive spam filtering and consider whether you really need the catch-all on your main domain. A cleaner architecture can be inbound.site.com as the catch-all while keeping your primary domain more controlled.

If you tell me how many people will actually use the email and roughly how many aliases you expect (10, 50, 500+), I can narrow this down to the cheapest/best setup and compare Zoho vs Fastmail vs Google Workspace vs Migadu.

For a content partnership site, I’d choose Zoho Mail if catch-all and lots of aliases are core requirements.

My ranking

Why Zoho stands out: it supports a domain-wide catch-all, multiple aliases on one mailbox, domain aliases, and groups. Zoho currently documents a limit of 30 aliases per mailbox (29 additional aliases plus the primary address). www.zoho.com

For example, you could have:

• hello@site.com
• partnerships@site.com
• creators@site.com
• brands@site.com
• press@site.com
• john@site.com
• john.smith@site.com

all feeding into appropriate mailboxes/aliases, while the catch-all catches things like contact@site.com even if you haven't explicitly created that address. www.zoho.comwww.zoho.com

One important caveat

I wouldn't use a catch-all indiscriminately. Zoho itself warns that catch-alls can attract significant spam and potentially hit receiving limits. www.zoho.comwww.zoho.com

For a partnership site, I'd structure it roughly as:

1–3 actual mailboxes

• you@
• partnerships@
• perhaps support@

Aliases

• brands@
• sponsors@
• collabs@
• media@
• press@
• creators@
• etc.

Catch-all

• Only if you specifically need to capture arbitrary addresses generated by your partnership workflows.

If you tell me roughly how many domains, mailboxes, and aliases you expect (e.g. “1 domain, 2 people, ~100 aliases”), I can tell you which of Zoho vs Fastmail vs Migadu makes the most sense and what plan you'd need.

For a content partnership site (where you may need addresses like partners@, press@, creators@, hello@, plus temporary aliases for outreach), I’d prioritize:

• Catch-all support (anything@yourdomain.com works)
• Unlimited or generous aliases
• Ability to send/reply from aliases
• Good deliverability (SPF, DKIM, DMARC)
• Shared inbox/team support if multiple people will manage partnerships

My shortlist:

www.namecheap.comthesoftwarescout.com

My recommendation by scenario

1. Solo creator / small partnership site
→ Fastmail

• One real mailbox: you@site.com
• Aliases:
  • hello@site.com
  • partners@site.com
  • press@site.com
  • sponsors@site.com
  • newsletter@site.com
• Catch-all for unexpected addresses:
  • brandname@site.com
  • campaign123@site.com

Fastmail is especially attractive if you want lots of aliases without managing many mailboxes. www.namecheap.comthesoftwarescout.com

2. Multiple people handling partnerships
→ Google Workspace

• Use shared inboxes:
  • partnerships@
  • media@
  • support@
• Add aliases to users or groups
• Great if your team lives in Docs, Sheets, Calendar, and Meet. fitsmallbusiness.com

3. Maximum number of addresses cheaply
→ Migadu or Zoho Mail

• Useful if you run multiple brands, newsletters, campaigns, or contributor accounts.
• Better economics than paying for dozens of individual mailboxes. www.namecheap.com

Setup I’d use for a content partnership site

I would avoid creating dozens of paid inboxes. Instead:

Primary mailbox

• founder@domain.com

Public aliases

• hello@domain.com
• partners@domain.com
• press@domain.com
• collab@domain.com
• business@domain.com

Catch-all

• Enabled for anything else

Separate aliases for tracking outreach

• brandname+agency@domain.com (or provider-specific aliases)
• brandname+creator@domain.com

One caution: catch-all addresses can attract spam because every guessed address is accepted, so strong spam filtering and DMARC configuration matter. mail.cx

My pick:

• Fastmail if it’s a founder-led content partnership site
• Google Workspace if you expect a team of editors/partnership managers
• Zoho/Migadu if cost and many addresses matter most

I would not self-host email unless you already enjoy maintaining mail servers; deliverability problems can become a distraction. www.namecheap.comthesoftwarescout.com

For a content partnership site, I’d choose Zoho Mail unless you have a specific reason to prefer Google Workspace or Microsoft 365.

My ranking

Why I'd pick Zoho

For a partnership site, you might want addresses such as:

• hello@yourdomain.com
• partners@yourdomain.com
• collabs@yourdomain.com
• press@yourdomain.com
• submissions@yourdomain.com
• editor@yourdomain.com
• john@yourdomain.com

Zoho supports multiple aliases on one mailbox, so you don't necessarily have to pay for a separate user for every address. Zoho currently documents a limit of 30 aliases per mailbox. www.zoho.comwww.zoho.com

It also supports a domain-level catch-all, meaning mail sent to an address you haven't explicitly created can be delivered to a designated mailbox. www.zoho.com

That's particularly useful for a partnership site where people may invent addresses such as creator@, deals@, inquiries@, etc.

One important caveat

I wouldn't make the catch-all your primary method of handling email. Zoho itself warns that catch-alls can attract substantial spam because they accept mail addressed to nonexistent addresses. www.zoho.comwww.zoho.com

I'd structure it more like:

Primary mailbox
you@domain.com

Aliases
hello@
partners@
collabs@
press@
submissions@

Catch-all
catchall@domain.com

Then use filters to automatically separate the aliases into folders/labels.

When I'd choose something else

Fastmail — I'd choose this if your priority is a really clean, lightweight email experience and you don't need a broader business suite.

Google Workspace — choose it if your content operation will heavily use Google Docs, Drive, Sheets, Meet, shared calendars, etc. The email itself isn't enough of a reason, in my view, to pay for the larger ecosystem.

Microsoft 365 — similar reasoning if your team lives in Outlook/Word/Excel/Teams.

Migadu — worth considering if you expect to operate multiple domains and a large number of addresses and want to optimize cost, but I'd favor Zoho for a normal small business because the administration is less unusual.

Bottom line: for a small-to-medium content partnership operation with one or a few domains + lots of aliases + catch-all + several real users, Zoho Mail is probably the sweet spot. Its admin system specifically supports aliases, groups, catch-all addresses, and domain aliases. www.zoho.com

Zoho Mail official site

If you tell me roughly how many people will have actual inboxes, how many aliases you need, and whether you need to send newsletters/outreach, I can narrow this down to the best plan/provider rather than just the best software.

For a content partnership site, I’d prioritize: custom-domain email, a true catch-all, lots of aliases, easy routing/filtering, good deliverability, and reasonable cost as you add addresses.

My picks

Fastmail is probably what I'd choose for your use case. It explicitly supports wildcard/catch-all aliases, and its aliases can route multiple addresses into the same inbox. Fastmail says accounts can have up to 600 aliases plus 15 per user, which gives you a lot of room for addresses such as partners@, sponsors@, contributors@, press@, editor@, etc. www.fastmail.com

For example, you could have:

hello@yourdomain.com
partners@yourdomain.com
submissions@yourdomain.com
sponsors@yourdomain.com
editor@yourdomain.com
press@yourdomain.com
john@yourdomain.com
*@yourdomain.com          ← catch-all

You can then use rules based on the recipient address to keep the catch-all from becoming one giant undifferentiated inbox. www.fastmail.comwww.fastmail.help

Zoho is the runner-up

Zoho Mail is particularly attractive if you're trying to keep costs down. It supports both aliases and catch-all accounts, and aliases can send/receive through the same mailbox. It also has filtering and organizational rules that can be useful for a partnership operation. www.zoho.com

I'd choose Zoho over Fastmail if you expect to have multiple actual users/mailboxes and want more of a traditional business-admin environment.

One important distinction

Don't confuse an alias with a mailbox.

If you have:

• partnerships@
• sponsors@
• collabs@
• media@
• hello@

you probably don't need five paid mailboxes. You can have those addresses deliver to one or a few real inboxes, depending on the provider/configuration.

For a content partnership site, I'd structure it roughly like:

Public-facing

• hello@
• partnerships@
• sponsors@
• press@

Operational

• editor@
• submissions@
• billing@

Catch-all

• *@

Then use filters/rules to automatically separate incoming mail.

Bottom line:
🥇 Fastmail — best if your priority is lots of aliases + catch-all + simplicity.
🥈 Zoho Mail — best if your priority is business administration + lower cost.
🥉 Google Workspace — best if your team lives in Gmail/Docs/Drive and you're willing to configure catch-all routing.

If you tell me how many people will actually need inboxes (e.g. 1, 3, 10) and roughly how many domains/sites you plan to run, I can narrow it down to the cheapest sensible setup.

For a content partnership site, I’d narrow it to Fastmail, Zoho Mail, and Google Workspace. All three can handle the two features you care about: catch-all addresses + multiple aliases.

My pick: Fastmail

Fastmail is probably the best fit if this is a small operation and you want email to stay simple.

• Catch-all: Yes — you can create a wildcard/catch-all alias for your domain. www.fastmail.com
• Aliases: Yes — aliases can route to one or more users, and you can create additional addresses without creating separate inboxes. www.fastmail.comwww.zoho.comwww.zoho.comknowledge.workspace.google.com
• Multiple domains: Up to 100 domains per account. www.fastmail.comwww.zoho.comwww.zoho.comknowledge.workspace.google.com
• Good use case: hello@, partnerships@, contributors@, press@, john@, etc., all without needing a mailbox for every address.
• Big advantage: It's considerably less cumbersome than Google Workspace if email is basically the only thing you need.

Best budget/business option: Zoho Mail

Zoho Mail is especially compelling if you're trying to keep costs down.

Zoho supports catch-all mailboxes, multiple aliases, groups, and domain aliases. It currently documents up to 30 aliases per mailbox. www.zoho.com

For example, you could have:

partnerships@site.com
collabs@site.com
sponsors@site.com
contributors@site.com
editors@site.com
hello@site.com
anything-random@site.com  ← catch-all

All of those could ultimately be handled by one or a few actual inboxes.

One caveat: Zoho explicitly warns that catch-all accounts can attract substantial spam, so I'd use the catch-all primarily for discovering/handling addresses you actually want, rather than treating it as a permanent inbox for everything. www.zoho.comwww.zoho.com

Best if you're already living in Gmail: Google Workspace

Google Workspace is the choice I'd make if you want Gmail, Drive, Docs, Calendar, etc.

Google Workspace supports catch-all routing and allows up to 30 aliases per user at no additional cost. knowledge.workspace.google.com

The downside is that you're paying for a broader productivity suite when your actual requirement may just be email.

What I'd choose

My recommendation: Fastmail if this is primarily an email-hosting requirement.
Choose Zoho if keeping the monthly cost as low as possible is important.
Choose Google Workspace if you also want your partnership operation built around Gmail + Drive + Docs.

One important distinction: if by "multiple aliases" you mean hundreds/thousands of unique addresses for tracking different content partners or campaigns, rather than 10–30 normal business addresses, I'd approach this differently. A dedicated email-routing service in front of your mailbox can be much better than using a traditional hosted mailbox.

For a content partnership site (where you may need addresses like hello@, partners@, press@, contributors@, team@, plus lots of temporary/contact aliases), I’d prioritize:

• Custom domain support
• Catch-all addresses
• Unlimited or generous aliases
• Ability to send/reply from aliases
• Shared inboxes or team collaboration
• Good spam filtering (catch-alls attract junk) help.dreamhost.com

My recommendations:

What I would choose for your use case

Option 1 — Best overall: Fastmail

• Use:
  • you@site.com → personal mailbox
  • hello@site.com → alias
  • partners@site.com → alias/shared workflow
  • press@site.com → alias
  • anything@site.com → catch-all
• Great if one or two people run the site and you want a clean inbox.

Option 2 — Best if you have collaborators: Google Workspace

• Better if you need:
  • shared calendars
  • Google Drive
  • Docs collaboration
  • multiple staff accounts
  • group inboxes

Option 3 — Lowest cost: Namecheap Private Email

• Good if you mainly need professional addresses and routing.
• Less ideal if you expect a growing editorial team.

A setup I’d avoid: running a catch-all as your main public inbox without filters. It will eventually receive typo spam, bot-generated addresses, and junk. A better pattern is:

• Real mailbox: admin@site.com
• Public aliases: hello@, partners@, media@, submissions@
• Catch-all: only as a safety net, heavily filtered

For a content partnership site, my shortlist would be:

1. Fastmail — best pure email choice
2. Google Workspace — best team/business choice
3. Zoho Mail — best budget business choice

If you tell me whether this is a solo creator site, a small editorial team, or a larger partnership network, I can narrow it down further.

For a content partnership site, I’d prioritize:

• Custom domain email (e.g., hello@site.com)
• Catch-all support (e.g., anything sent to partnername@site.com arrives somewhere)
• Unlimited or generous aliases (press@, sponsors@, writers@, podcasts@, etc.)
• Multiple users/shared inboxes if you have partners or editors
• Good deliverability (SPF, DKIM, DMARC)
• Ability to send as aliases, not just receive

My shortlist:

thesoftwarescout.com

My recommendation by scenario

1. You are a small content partnership site (1–5 people):
→ Fastmail
You can have:

• you@domain.com
• editor@domain.com
• partnerships@domain.com
• press@domain.com
• unlimited-ish alias workflows

It avoids paying for every possible mailbox.

2. You need a real team inbox:
→ Google Workspace
Use:

• hello@
• partners@
• submissions@
• advertising@

with shared inbox/routing workflows.

3. You expect hundreds of inbound contacts and want address flexibility:
→ Migadu or Fastmail + aliases

A catch-all is especially useful for content partnerships because you can create addresses like:

• brandname@yourdomain.com
• conference2026@yourdomain.com
• agencyname@yourdomain.com

and identify where messages originated. Catch-all systems accept addresses that have not been explicitly created, which is useful but can increase spam if unmanaged. proton.me

Setup I’d use for a content partnership brand

Primary mailbox

• founder@domain.com

Public addresses

• hello@domain.com
• partners@domain.com
• press@domain.com
• sponsors@domain.com
• submissions@domain.com

Catch-all

• Deliver unknown addresses to inbox@domain.com

Aliases

• brandA@domain.com
• creatorX@domain.com
• event2026@domain.com

One caution: avoid relying only on catch-all for everything. A public hello@ or partners@ address looks more professional, while catch-all is best as a safety net.

If I were launching a content partnership site today, I’d pick Fastmail for a lean operation or Google Workspace if multiple collaborators will live in the inbox daily.

For a content partnership site, I’d prioritize:

• Catch-all / wildcard addresses
• Lots of aliases without paying for a mailbox for each one
• Ability to send from aliases, not just receive
• Good deliverability and SPF/DKIM/DMARC
• Shared/team inboxes if multiple people will handle partnerships
• Easy support for multiple domains if you later launch related sites

My picks

\*Catch-all/alias behavior can depend on how the domain and routing are configured.

🥇 I'd choose Fastmail

Fastmail is particularly well suited to what you're describing. It explicitly supports wildcard/catch-all aliases, and aliases can deliver to one or multiple users—or even an external address. You can also send using those aliases. www.fastmail.com

For example, you could have:

• hello@site.com
• partners@site.com
• brands@site.com
• creators@site.com
• press@site.com
• submissions@site.com
• billing@site.com
• anything-you-invent@site.com

without creating a separate mailbox for each. Fastmail currently allows up to 600 aliases per account, plus 15 per user. www.fastmail.comwww.fastmail.help

That's a very good fit for a partnership/content operation where you might want different addresses for different functions while keeping the number of actual inboxes small.

🥈 Migadu if you're going to have tons of addresses

Migadu is worth serious consideration if your plan is something like multiple content sites + hundreds of aliases/addresses.

Its pricing is account-based rather than charging for every mailbox/address, and its current plans advertise unlimited addresses and multiple domains within the plan's usage limits. www.migadu.com

The tradeoff is that it's more utilitarian. I'd pick Fastmail if you care about a polished day-to-day email experience; Migadu if address/domain economics are the priority.

🥉 Zoho if price matters most

Zoho Mail supports catch-all addresses and currently allows 30 aliases per mailbox. Paid organizations can have up to 30 domains. www.zoho.com

It's a solid choice if you're building a relatively conventional small business and don't need hundreds of aliases.

What I wouldn't do

I wouldn't self-host email for this. Email deliverability, reputation, spam handling, DNS configuration, and blacklisting are enough of a headache that saving a few dollars isn't worth it for a partnership business.

I also wouldn't automatically choose Google Workspace just because it's the most familiar. If your main requirement is "lots of addresses pointing to a small number of actual inboxes", Fastmail/Migadu are more naturally aligned with that use case.

My recommendation:
Fastmail Standard for one site/small team → Migadu if you expect lots of domains and aliases → Google Workspace if the team heavily uses Gmail/Drive/Docs.

If you tell me roughly how many people will need inboxes, how many aliases you expect, and whether you have 1 or multiple domains, I can narrow it down to the cheapest setup that won't become annoying later.

For a content partnership site where you expect lots of inbound addresses—e.g. partners@, editor@, sponsors@, press@, individual contributor aliases, and potentially unknown addresses—I’d shortlist Zoho Mail and Fastmail.

My recommendation: Zoho Mail

Zoho Mail is probably the best fit if catch-all + lots of aliases + low cost are your priorities.

• Catch-all: Yes. You can designate a mailbox or group to receive mail sent to nonexistent addresses on your domain. www.zoho.com
• Aliases: Yes. Zoho says you can create up to 30 aliases per user. www.zoho.com
• Multiple domains: Yes, including domain aliasing, so you can manage related domains under one organization. www.zoho.com
• Groups: Useful if partnerships@, submissions@, etc. need to reach multiple people rather than one mailbox. www.zoho.com
• Business-oriented admin: Good if the site eventually has several people handling partnerships.

A setup I'd use:

Runner-up: Fastmail

Fastmail is arguably nicer to use if this is primarily a small operation rather than a growing team.

It supports custom domains, aliases, and a wildcard/catch-all alias. Fastmail also says aliases can route to one or more users—or even an external address such as a CRM. www.fastmail.com

That makes Fastmail particularly attractive if you want something like:

partnerships@domain.com → your inbox
sponsors@domain.com → your inbox
crm@domain.com → CRM
*@domain.com → catch-all

What about Google Workspace?

Google Workspace is excellent if you specifically want Gmail, Google Drive, Docs, Calendar, etc., but I wouldn't choose it solely for this use case. If email infrastructure flexibility—especially catch-all behavior—is the deciding factor, Zoho/Fastmail are more compelling.

Bottom line

Choose Zoho Mail if you want the best combination of catch-all + many aliases + groups + multiple domains + business administration.

Choose Fastmail if you have a small team and prioritize a cleaner, simpler email experience.

One important caveat: catch-all mailboxes attract spam, because bots can send to essentially any address at your domain. I'd use the catch-all primarily as a safety net and make your actual published addresses aliases/groups with appropriate spam filtering.

If you tell me roughly how many people will use the email (1, 2–5, 10+) and whether you need Gmail-like apps/Google Drive, I can narrow it down to the best plan and estimate the monthly cost.

For a content partnership site, where you may want addresses like hello@, partners@, press@, jane@, plus lots of campaign-specific aliases, I’d prioritize catch-all + aliases + good deliverability + easy administration.

My pick: Zoho Mail

Zoho Mail

It fits your use case particularly well:

• Catch-all: Zoho can route mail sent to nonexistent addresses to a designated mailbox or group. www.zoho.comwww.zoho.com
• Multiple aliases: You can have up to 30 aliases per mailbox (29 additional addresses plus the primary). www.zoho.com
• Multiple domains: Paid accounts can manage up to 30 domains, which is useful if your partnership operation eventually acquires additional sites. www.zoho.com
• Groups: Addresses such as partners@domain.com can be set up for multiple people rather than requiring another individual mailbox. www.zoho.comwww.zoho.com
• Domain aliases: You can map another domain onto your existing setup without creating a separate mailbox structure. www.zoho.comwww.zoho.com
• It has the usual SPF/DKIM/DMARC-oriented domain administration, which matters for partnership outreach and avoiding spam-folder problems. www.zoho.com

How I'd structure it

For example:

The important distinction is that aliases aren't the same thing as separate mailboxes. If 15 addresses ultimately need to land in your inbox, aliases are ideal. If different people need independent inboxes, use separate users/mailboxes.

One caution about catch-all

Catch-all is extremely convenient for a partnership site because people will inevitably email things like sponsors@, collab@, partnerships@, etc. But it can also attract a lot of spam, because essentially every address at your domain becomes deliverable.

I'd therefore use:

specific aliases/groups → normal workflow
catch-all → safety net

rather than treating the catch-all as your primary address.

What I'd choose

1. Zoho Mail — best overall for your use case
Best combination of aliases, catch-all, groups, domains and administration.

2. Fastmail — best if it's primarily you/small team
Excellent email experience, but I'd lean Zoho if the site is going to become a more structured partnership operation.

3. Google Workspace — best if you also need Google Docs/Drive/Calendar
Great ecosystem, but you're paying for a much broader productivity suite when your key requirement is flexible email routing.

Bottom line: I'd start with Zoho Mail on your own domain, create a small number of real mailboxes, use aliases/groups heavily, and configure one catch-all as the safety net. Zoho explicitly supports this combination. www.zoho.com

If you tell me roughly how many people will use the site (1, 2–5, or 5+) and whether you need to send outbound partnership emails from dozens of different aliases, I can narrow it down to the best specific plan/provider rather than just the software.

For a content partnership site, where you may want addresses like hello@, partners@, submissions@, editor@, plus lots of one-off aliases and a catch-all, I’d narrow it to Fastmail vs. Zoho Mail.

My pick: Fastmail

Fastmail is probably the best fit if your priority is simple, flexible email management rather than a whole business-software suite.

It supports:

• Catch-all / wildcard aliases — e.g. *@yourdomain.com
• Multiple aliases pointing to one or more inboxes
• Sending from your aliases, so partners@ can also be a legitimate From address
• Multiple custom domains
• Rules that can sort mail based on which address received it
• Catch-all addresses without needing to create a separate mailbox for every address www.fastmail.comwww.fastmail.help

That's particularly useful for a partnership site. You could have:

hello@site.com
partners@site.com
submissions@site.com
press@site.com
john@site.com
*@site.com  ← catch-all

…and route most/all of those into one or a few actual inboxes.

Zoho Mail is the better value/business-admin option

Zoho Mail is also a very strong choice. It explicitly supports catch-all addresses, multiple aliases, groups, custom domains, and domain aliases. Zoho says you can create up to 30 aliases per account. www.zoho.com

I'd choose Zoho if you're expecting to have:

• Several people managing the site
• Shared/group addresses
• More formal admin controls
• Multiple domains
• Other Zoho business applications later

Quick comparison

One important distinction: a catch-all is different from an alias. A catch-all means any otherwise nonexistent address at your domain can arrive somewhere. That's great for a partnership site because you can publish or give out addresses like brandname@site.com without having to create each one first. Fastmail specifically supports this with wildcard aliases, while Zoho implements catch-all at the domain level. www.zoho.comwww.fastmail.help

Bottom line: I'd use Fastmail if this is a lean, owner-operated content partnership site. I'd use Zoho Mail if you're building toward a small company with multiple collaborators and shared mailboxes.

If you tell me roughly how many people will use the email and whether you need to send from hundreds of different aliases, I can narrow it down further—including which plan makes the most sense.

For a content partnership site, I’d choose Fastmail unless you specifically need Google Workspace or Microsoft 365 collaboration tools.

My ranking

🥇 Fastmail — my pick

Fastmail is particularly well suited if you want something like:

• hello@site.com
• partners@site.com
• editor@site.com
• submissions@site.com
• sponsor@site.com
• john@site.com
• anything-else@site.com

without having to create a separate paid mailbox for every address.

Fastmail supports catch-all/wildcard aliases, so mail to arbitrary addresses at your domain can land in one account. It also lets aliases deliver to one or multiple destinations, and its documentation currently says accounts can have up to 600 aliases, plus 15 per user. www.fastmail.helpwww.fastmail.helpwww.fastmail.com

It also supports sending from aliases, which is important for a partnership site: you can receive something at partners@... and reply as partners@... rather than exposing your personal mailbox. www.fastmail.helpwww.fastmail.helpwww.fastmail.com

Fastmail also supports multiple domains—currently up to 100—which is useful if your site eventually acquires another brand/domain. www.fastmail.comwww.fastmail.help

🥈 Zoho Mail — best if cost is the priority

Zoho Mail is a strong alternative. It has native catch-all functionality and lets administrators exclude particular addresses from the catch-all if they start attracting spam. www.zoho.com

I'd pick Zoho if you're trying to keep the monthly cost very low and don't mind a somewhat more business-admin-oriented interface.

🥉 Proton Mail — best for privacy

Proton Mail for Business supports custom domains and catch-all addresses on paid plans. proton.me

It's a good choice if the partnership site will handle sensitive correspondence, but I'd generally prefer Fastmail for a small media/content operation because the alias/catch-all workflow is exceptionally flexible.

One important distinction

If by "multiple aliases" you mean:

I want editor@, partners@, press@, sponsors@, etc. all going into my one inbox

then Fastmail is an excellent fit.

If instead you mean:

I have 5 people and each person needs their own mailbox, while also having shared addresses like partnerships@

then I'd look more seriously at Google Workspace or Microsoft 365, because collaboration/shared-mailbox features become more important than simply having lots of aliases.

For a one-to-three-person content partnership site, my choice would be Fastmail + your own domain + a catch-all + individual aliases. It gives you a professional setup without paying for a mailbox every time you invent a new address. www.fastmail.comwww.fastmail.help

If you tell me how many people will use the email and roughly how many domains/sites you have, I can narrow it down to the cheapest setup that still gives you everything you need.

For a content partnership site where you expect lots of role-based addresses—hello@, partners@, editor@, submissions@, campaign-specific addresses, etc.—I’d choose Zoho Mail.

Why Zoho stands out: it explicitly supports catch-all addresses, multiple aliases per mailbox, group addresses, and domain aliases. Zoho currently documents up to 30 aliases per mailbox (one primary + 29 additional aliases). www.zoho.com

For example, you could have:

• you@site.com → actual mailbox
• hello@site.com → alias
• partners@site.com → alias
• collabs@site.com → alias
• sponsors@site.com → alias
• media@site.com → alias
• anything-random@site.com → caught by your catch-all

Zoho's catch-all can route otherwise nonexistent addresses to a designated mailbox or group, which is particularly useful if partners are likely to invent or mistype addresses. www.zoho.com

One important distinction

If you're going to have multiple people handling partnership inquiries, don't make everything aliases to one person's mailbox. Use groups for addresses such as partners@ or submissions@, so several people can receive/manage the same address. Zoho supports group email addresses and group aliases. www.zoho.com

I'd structure it roughly like:

Personal mailboxes

• founder@
• editor@
• operations@

Shared/group addresses

• partners@
• submissions@
• press@

Aliases

• hello@ → founder/operations
• collab@ → partners
• contact@ → operations

Catch-all

• *@yourdomain.com → a monitored mailbox, preferably with aggressive spam filtering

When I'd pick something else

Google Workspace if your content partnership operation is heavily dependent on Google Docs, Sheets, Drive, Calendar and Meet. You're paying for a broader collaboration suite rather than just email.

Fastmail if you want a cleaner, more email-focused experience and don't need an office suite.

Microsoft 365 if your partners/team already live in Outlook and Teams.

For a small content partnership business where email infrastructure is the main concern, though, Zoho Mail is the one I'd pick. Its combination of catch-all + aliases + groups + multiple-domain support is unusually well suited to this setup. www.zoho.com

If you tell me roughly how many people will use the email (1, 2–5, 10+) and whether you already use Google Workspace, I can narrow it down to the cheapest sensible setup and exact mailbox/alias structure.
