If your priority is the cheapest option that still gives you solid GDPR/CCPA-friendly consent and opt-in management, I’d pick Brevo.

My ranking

Why Brevo wins: its free plan supports unlimited contacts and up to 300 emails/day, while Brevo explicitly advertises GDPR & CCPA compliance features including customizable forms, consent records, and data-request management. www.brevo.com

MailerLite is also very good: its forms have built-in GDPR settings, permission checkboxes, and double opt-in, and it states that the platform has GDPR controls and procedures. But its free plan is limited to 250 subscribers. www.mailerlite.com

What I'd choose

• Small list + want the simplest interface: MailerLite
• Large list + relatively few emails: Brevo
• Want $0 cost for as long as possible: Brevo
• Need explicit consent records / CCPA-oriented data requests: Brevo

One important caveat: “GDPR/CCPA compliant tool” doesn't make your email marketing automatically compliant. You still need appropriate privacy notices, lawful consent where required, unsubscribe mechanisms, retention practices, and to configure the consent fields correctly.

If you tell me roughly how many subscribers you have and how many emails you send per month, I can calculate which one will actually be cheapest for you—including the paid tiers.

If your priority is the cheapest option that still gives you solid GDPR/CCPA-friendly consent and opt-in management, I’d pick brevo.com.

• If you outgrow free, Starter begins at $9/month, with 5,000 emails/month at the entry tier. Brevo Help

How I'd rank the cheap options

MailerLite's free plan is also attractive, but it's limited to 250 subscribers and 2,500 emails/month; its paid Comfort plan starts at $12/month. MailerLite MailerLite

One important distinction: no email platform magically makes your marketing GDPR/CCPA compliant. You still need the right privacy notice, lawful basis/consent wording, data-processing arrangements, retention practices, etc. But if what you specifically want is built-in consent capture + opt-in/opt-out management without paying much, Brevo is the strongest cheap choice.

If you tell me roughly how many contacts you have (e.g. 500, 5k, 20k) and how many emails you send/month, I can tell you which one is actually cheapest at your scale.

If GDPR/CCPA-friendly consent + opt-in management are must-haves and you want the lowest cost, I’d pick brevo.com.

My ranking

Why Brevo wins: its free plan supports up to 300 emails/day, and Brevo explicitly provides GDPR/CCPA compliance features including customizable consent forms, consent records, and data-request management. Brevo Brevo

If you need more sending volume, Brevo's paid Starter plan currently starts around $9/month (or $8.08/month with annual billing). Brevo

MailerLite is a very close second. Its free tier is $0 for up to 250 subscribers and 2,500 emails/month, with GDPR-specific form settings, consent checkboxes, double opt-in, and subscriber preference management. MailerLite MailerLite MailerLite Its more advanced Preference Center is particularly good if by “opt-in management” you mean letting subscribers choose which types of emails they receive. MailerLite

Bottom line

• Cheapest + strongest compliance tooling: Brevo
• Cheapest + easiest GDPR-focused setup: MailerLite
• If you're just starting: I'd use Brevo's free plan unless you specifically want MailerLite's interface/preference-center workflow.

One caveat: “GDPR/CCPA compliant” doesn't mean the software makes your business automatically compliant—you still need appropriate privacy notices, lawful consent, retention practices, etc.

If you tell me roughly how many subscribers you have and how many emails/month you send, I can tell you which is actually cheapest at your scale.

MailerLite is a very close second. Its free tier is $0 for up to 250 subscribers and 2,500 emails/month, with GDPR-specific form settings, consent checkboxes, double opt-in, and subscriber preference management. Its more advanced Preference Center is particularly good if by “opt-in management” you mean letting subscribers choose which types of emails they receive.

If your priority is lowest cost while still having GDPR/CCPA-friendly consent collection, opt-in tracking, and unsubscribe/preference management, I’d shortlist these:

My recommendation by scenario

• Small business / newsletter / startup: choose Brevo. It gives you the best compliance-to-price ratio: you can start free, keep consent records, and enable proper opt-in flows without paying for a large marketing suite. www.brevo.com
• You only need basic newsletters and have a small list: MailerLite is also a strong low-cost option. www.sequenzy.commailtoolfinder.com
• You need the absolute cheapest paid plan: look at Zoho Campaigns, assuming its automation/features fit your workflow. www.sequenzy.com
• You run a SaaS/product with more complex lifecycle emails: you may outgrow cheap newsletter tools; consider something with stronger event-based consent controls.

A couple of important caveats:

• An email platform being “GDPR compliant” does not make your business automatically compliant. You still need a lawful basis for processing, a privacy policy, correct consent wording, and proper recordkeeping.
• For GDPR marketing emails, look for: explicit opt-in checkbox (not pre-checked), consent timestamp/source, double opt-in support, unsubscribe links, suppression lists, and deletion/export workflows.

If you tell me your subscriber count, monthly email volume, and whether this is for newsletter vs SaaS/product emails vs ecommerce, I can narrow it to the cheapest fit.

If your priority is lowest cost + GDPR/CCPA-friendly consent + opt-in management, I’d pick Brevo.

Best budget choice: Brevo

Brevo explicitly states that it supports GDPR & CCPA compliance, including customizable signup forms, consent records, and data-request management. Its free tier allows unlimited contacts and up to 300 emails/day. The paid Starter plan starts at $9/month for 5,000 emails/month. www.brevo.com

Why I'd choose Brevo: its pricing is based primarily on emails sent rather than contacts stored, so you can have a relatively large consented database without paying simply for keeping those contacts. That becomes particularly attractive if you have lots of subscribers but don't email them constantly. www.brevo.commailcompare.eu

One important distinction: "GDPR/CCPA compliant tool" doesn't automatically make your marketing compliant. You still need to configure the forms correctly—e.g. affirmative consent where required, clear purpose/language, unsubscribe mechanisms, and appropriate records of consent.

If you tell me roughly how many contacts you have and how many emails you send per month (e.g. 2,000 contacts / 4 newsletters per month), I can calculate the cheapest option among Brevo, MailerLite, Mailchimp, Kit, Sender, and others for your exact usage.

If your priority is the cheapest option that still gives you solid GDPR/CCPA-friendly consent and opt-in management, I’d pick Brevo.

My pick: Brevo

Why:

• Free plan: $0/month, with up to 300 emails/day and up to 100,000 stored contacts. help.brevo.com
• Explicitly supports GDPR & CCPA compliance, including customizable forms, consent records, and data-request management. www.brevo.com
• Supports double opt-in, which gives you a stronger consent trail. help.brevo.com
• Its forms can include dedicated GDPR consent fields/declarations. help.brevo.com
• Paid Starter begins at $9/month, so it remains inexpensive as you grow. help.brevo.com

One caveat: Brevo's more advanced "consent groups" feature is only on Professional/Enterprise, so you don't get every consent-management feature on the cheap plans. help.brevo.com

How I'd rank the cheap options

MailerLite's free tier is also $0 for up to 250 subscribers, while its $12/month Comfort plan adds a subscriber preference center and other management features. www.mailerlite.com

Bottom line: If you're starting small and want legitimate consent/opt-in infrastructure without paying for a dedicated consent-management platform, I'd start with Brevo Free. If you tell me roughly how many subscribers you have + how many emails/month you send, I can calculate the cheapest option at your actual scale. Brevo official site

If your priority is the cheapest option that still has solid GDPR/CCPA-friendly consent and opt-in management, I’d pick Brevo.

My ranking

Brevo is the one I'd choose if you're trying to spend as little as possible. Its free plan is $0 and currently allows up to 100,000 contacts, although you're limited to 300 email sends per day. More importantly, Brevo explicitly provides GDPR/CCPA-oriented features including customizable forms, consent records and data-request management. help.brevo.com

Its forms can enable GDPR consent fields, and it supports double opt-in, which gives you a stronger record of affirmative subscription consent. help.brevo.com

Brevo pricing

When I'd choose something else

Choose Kit if you're primarily a newsletter/creator business and want particularly explicit consent-management functionality. Kit has GDPR/CCPA-specific tooling, including consent tags, consent checkboxes, EU subscriber filtering, double opt-in, and a DPA. kit.com

Choose MailerLite if you care more about ease of building newsletters, landing pages, and automations. Its free tier supports up to 250 subscribers and 2,500 monthly emails; the paid Comfort tier starts at $12/month and adds a preference center and more advanced tools. www.mailerlite.com

Bottom line

For cheapest + legally sensible consent infrastructure: Brevo.

One caveat: no email platform makes your marketing automatically GDPR/CCPA compliant. Your privacy notice, consent language, lawful basis, retention practices, cookie/advertising practices, and how you use the data still matter.

If you tell me roughly how many subscribers you have and how many emails you send per month, I can compare the actual monthly cost of Brevo vs MailerLite vs Kit and tell you which is cheapest at your scale.

If your priority is the lowest cost while still having solid GDPR/CCPA-oriented consent and opt-in management, I’d shortlist Brevo, Zoho Campaigns, and MailerLite.

My pick: Brevo

Brevo is probably the best overall fit.

• Free plan: up to 300 emails/day, with unlimited contacts. www.brevo.com
• Paid: starts at $9/month for 5,000 emails/month. www.brevo.com
• Built-in GDPR consent fields, privacy-policy declaration, and double opt-in. help.brevo.comhelp.brevo.com
• Supports separate lists/preferences for different consent purposes, which is useful if you need people to opt into different types of marketing. help.brevo.comhelp.brevo.com
• Brevo explicitly advertises GDPR & CCPA compliance tooling, including customizable forms, consent records, and data-request management. www.brevo.com

The big advantage is its pay-per-email model. If you have, say, 5,000–20,000 subscribers but don't email them constantly, Brevo can be substantially cheaper than services that charge primarily by subscriber count. www.etropo.comwww.mailerlite.comwww.mailerlite.com

Cheapest alternative: Zoho Campaigns

Zoho Campaigns is worth considering if you want to squeeze the cost down as far as possible.

Its Forever Free tier supports up to 2,000 contacts and 6,000 emails/month. www.zoho.com It also has:

• double opt-in
• consent records
• opt-in/unsubscribe management
• signup forms
• GDPR compliance features
• consent emails and consent/deny mechanisms. www.zoho.com

So Zoho is potentially the cheapest if your volume fits inside the free tier.

Best/easiest: MailerLite

MailerLite is another strong choice. Its forms have built-in GDPR settings, consent checkboxes, privacy-policy fields, and double opt-in. www.mailerlite.com

However, its current free plan is only 250 subscribers, while the paid Comfort plan starts at $12/month. www.mailerlite.com

What I'd choose

One important caveat: no email platform makes your marketing automatically GDPR/CCPA compliant. You still need the right privacy notice, lawful basis/consent wording, unsubscribe process, data-retention practices, etc. Brevo itself explicitly notes that its guidance isn't legal advice. help.brevo.comhelp.brevo.com

If you tell me roughly how many subscribers you have (e.g. 500, 2,000, 10,000) and how many emails you send per month, I can calculate which of these is actually cheapest for you.

If your priority is lowest cost + solid GDPR/CCPA-friendly consent and opt-in management, I’d pick Brevo.

My ranking

Why Brevo wins: its free plan is $0, allows up to 100,000 stored contacts, and gives you 300 email sends/day. More importantly for your requirement, Brevo explicitly supports GDPR/CCPA compliance, customizable forms, consent records, and data-request management. help.brevo.com

Its forms can include a GDPR consent field, privacy-policy declaration, preference/list selection, and double opt-in. help.brevo.com

The catch: Brevo's more sophisticated Consent Groups feature—which lets subscribers independently opt into/out of different communication topics—is restricted to Professional/Enterprise plans. help.brevo.com

MailerLite is my second choice. It also states that its platform complies with GDPR and various US privacy laws, and its free plan includes signup forms and automations for up to 250 subscribers. Its paid Comfort plan starts at $12/month and adds a preference center and unsubscribe-page builder. www.mailerlite.com

Bottom line

• Need the absolute cheapest: Brevo Free
• Need a nicer/simpler email-marketing experience: MailerLite
• Need sophisticated consent categories/preferences: Brevo, but budget for a paid tier.

One important caveat: “GDPR/CCPA compliant tool” doesn't make your email program automatically legally compliant. Your consent language, privacy notice, tracking practices, lawful basis, retention/deletion procedures, and how you handle unsubscribe/DSAR requests still matter.

If your priority is the cheapest option that still gives you solid GDPR/CCPA-friendly consent and opt-in management, I’d pick Brevo.

My ranking

Brevo's free plan currently allows 300 emails/day and up to 100,000 contacts, and its signup forms can include GDPR consent fields, privacy declarations, preference/list selection, and double opt-in. help.brevo.com

Brevo also explicitly describes its platform as GDPR & CCPA compliant, including customizable forms, consent records, and data-request management. www.brevo.com

Kit is particularly good if you're a creator/newsletter business: it has built-in consent checkboxes, GDPR/CCPA support, a DPA, and double opt-in. kit.com But its paid Creator plan starts at $39/month for 1,000 subscribers, so it's hard to justify if price is the main consideration. help.kit.com

Bottom line

I'd start with Brevo. You can stay on the free plan while your list is small, and you get the consent/opt-in infrastructure you're looking for without immediately paying for a premium plan.

One caveat: no email platform makes your marketing automatically GDPR/CCPA compliant. You still need appropriate privacy notices, lawful-basis decisions, consent wording, retention practices, and so on. Brevo itself notes that its form guidance isn't legal advice. help.brevo.comhelp.brevo.com

If you tell me roughly how many subscribers you have (e.g. 500, 5k, 20k) and how many emails/month you send, I can compare the actual monthly cost of Brevo vs MailerLite vs Kit and tell you which is cheapest at your scale.

If your priority is the cheapest option that still gives you real GDPR/CCPA-friendly consent and opt-in management, I’d pick MailerLite.

MailerLite explicitly says it has the necessary GDPR controls/procedures, stores data in the EU, and requires permission-based sending. Its policies also prohibit pre-checked consent boxes and require a clear way to revoke consent. www.mailerlite.com

Why I'd choose MailerLite

If you're under 250 subscribers, you can start at $0. The free plan includes 2,500 emails/month, signup forms, automations, landing pages, and subscriber management. www.mailerlite.com

Once you exceed that, the current Comfort plan starts at $12/month for up to 500 subscribers, and adds things particularly relevant to consent management such as a subscriber preference center. www.mailerlite.com

Brevo is my second choice if you anticipate having lots of contacts but sending relatively few emails, because its pricing is based heavily on email volume rather than simply the size of your contact database. Its free tier supports up to 100,000 stored contacts and 300 emails/day. help.brevo.com

Kit is the strongest of the three for explicit consent tooling—it has GDPR consent checkboxes, consent tags, EU/EEA subscriber identification, double opt-in, and a DPA covering GDPR/CCPA-related processing. kit.com But if cheap is the deciding factor, I'd go MailerLite.

Bottom line: → MailerLite.
If you tell me roughly how many subscribers you have (or expect) and how many emails/month you'll send, I can tell you which is cheapest at your actual scale and compare MailerLite vs. Brevo vs. Kit.

If your priority is lowest cost while still having GDPR/CCPA-friendly consent collection and opt-in management, I’d narrow it to these:

My recommendation:

• Small business / newsletter / under ~10k subscribers: pick Brevo. It gives you the best compliance-to-cost ratio because pricing is based more on sending volume than contact count, and it includes consent-related tools. www.brevo.com
• You only need basic newsletters and want the simplest interface: pick MailerLite. mailtoolfinder.com
• You need serious automation (behavior triggers, CRM-style journeys): consider ActiveCampaign later, but it is not the cheapest route. www.sequenzy.comwww.brevo.com

One important caveat: no email platform alone makes you GDPR/CCPA compliant. You still need:

• clear, unchecked marketing consent boxes
• records of when/how someone opted in
• unsubscribe links
• a process for deletion/access requests
• only emailing people for the purposes they consented to

For a lean setup, I’d start with Brevo + a GDPR-compliant signup form + double opt-in enabled. www.sequenzy.comwww.brevo.com

If lowest cost + solid GDPR/CCPA consent and opt-in management is the priority, I’d choose Brevo.

Brevo explicitly advertises GDPR & CCPA compliance, including customizable forms, consent records, and data-request management. Its forms support a GDPR consent field and double opt-in, which gives you a useful audit trail of affirmative subscription consent. www.brevo.com

The cost advantage is significant: Brevo has a free plan with 300 emails/day, and its Starter plan begins at $9/month for 5,000 emails/month. help.brevo.com

MailerLite is also explicitly GDPR compliant and has a free tier, but its free plan is limited to 250 subscribers; its paid Comfort plan starts at $12/month. www.mailerlite.com

My recommendation

Pick Brevo if:

• You want to spend $0 initially
• You need explicit consent/opt-in handling
• You want double opt-in
• You need GDPR/CCPA-oriented data controls
• You don't want pricing to jump just because your contact list grows

Pick MailerLite instead if your main priority is a polished newsletter/blog experience and you're comfortable paying $12/month once you exceed the free tier.

One important caveat: “GDPR/CCPA compliant tool” doesn't automatically make your marketing legally compliant. Your forms, privacy notice, consent language, lawful basis, data retention, unsubscribe process, and how you use the collected data still matter.

If you tell me roughly how many subscribers you have and how many emails you send per month, I can compare the actual cheapest 3–5 options for your volume.

If your priority is the cheapest email tool that still gives you GDPR/CCPA-friendly consent handling and opt-in management, I’d shortlist these:

www.sequenzy.commailtoolfinder.com

My recommendation by scenario

Cheapest while still feeling “compliance-ready”: → Brevo
It’s usually the best value because pricing is based more on sends than contacts, and it includes the basics you need: consent tracking, opt-in workflows, unsubscribe management, and privacy documentation. www.sequenzy.com

Small newsletter (<1,000 subscribers): → MailerLite
A good choice if you mainly need signup forms, double opt-in, and a clean preference center. www.sequenzy.commailtoolfinder.com

Bare-minimum budget: → Zoho Campaigns
If you only need compliant opt-in collection and basic campaigns, it can be extremely inexpensive. www.sequenzy.com

A few things to verify before choosing any provider:

• ✅ Double opt-in available (especially for GDPR audiences)
• ✅ Consent timestamp stored
• ✅ Ability to export/delete subscriber data (DSAR requests)
• ✅ DPA available
• ✅ Preference center or granular unsubscribe options
• ✅ CCPA/CPRA support for opt-out and deletion requests

One caveat: an email platform being “GDPR/CCPA-friendly” does not make your marketing automatically compliant—you still need correct signup language, lawful consent collection, and proper records. www.wordstream.com

For most small businesses, I’d pick Brevo first, MailerLite second. If you tell me your approximate list size (0–500, 500–5k, 5k+) and whether you send newsletters, ecommerce emails, or SaaS lifecycle emails, I can narrow it down further.
