ChatGPT answers, unedited

Yes. What you’re describing is generally called a visual marketing automation / customer journey builder: you drag triggers, emails, SMS steps, delays, conditions, and branches onto a canvas.

A few strong options:

The two I'd look at first

Customer.io is probably the closest match if you mean something like:

                    ┌─ Email #1
                    │
Signup ──> Wait 1d ─┤
                    │
                    └─ SMS #1
                         │
                       Wait 2d
                         │
                   ┌─────┴─────┐
                Opened?       Didn't open?
                   │               │
                Email #2        SMS #2

Its current visual workflow builder supports drag-and-drop blocks, delays, conditional/multi-way branches, triggers, and email/SMS in the same journey. customer.io

Klaviyo is especially compelling if you're doing ecommerce. Its Flows builder lets you create drag-and-drop, cross-channel workflows containing email, SMS and push, with behavioral triggers and conditional splits. www.klaviyo.com

If you're building something yourself

If by "a platform" you mean you want to build your own platform that works this way, that's also very doable. The core product would essentially be:

Visual canvas → workflow graph → trigger/condition engine → message composer → email/SMS providers → analytics

And you could make the UI resemble a mix of Zapier + Klaviyo, where users literally drag:

• Trigger
• Send Email
• Send SMS
• Wait
• If/Else
• A/B Split
• Exit
• Goal
• Webhook
• Update contact

onto a canvas.

If that's what you're considering, I can also show you what the architecture/database model for building a Klaviyo-style visual email + SMS workflow platform would look like.

Yes. There are several platforms that do exactly this—visual, drag-and-drop customer journeys where email and SMS can be steps in the same sequence.

My top picks

If you mean something like this

You'd be able to visually construct:

New lead enters → Wait 10 min → Send Email → Wait 1 day → Did they open?

→ YES: Send SMS → Wait 2 days → Send Email 2
→ NO: Wait 1 day → Send Email 2 → Send SMS

That's particularly well supported by Customer.io. Its current workflow builder is a true drag-and-drop canvas with delays, conditional branches, behavioral triggers, and email/SMS in the same workflow. docs.customer.io

Klaviyo is probably the closest alternative if this is primarily for ecommerce. Its Flows builder supports email, SMS, and push in one flow, with behavioral triggers and branching. www.klaviyo.com

Omnisend is worth looking at if you want something easier to get started with; its automation editor explicitly lets you combine email, SMS, and web push, with drag-and-drop paths and splits. www.omnisend.com

If you're building a SaaS/product rather than looking for a marketing tool, I'd lean Customer.io. If you're selling products online, I'd lean Klaviyo.

If you tell me what you're selling + roughly how many contacts you have, I can narrow this down to the 2–3 best options and compare pricing, workflow flexibility, SMS capabilities, and ease of use.

Yes. There are several platforms built around visual workflow editors where you drag-and-drop triggers, delays, conditions, emails, and SMS steps into customer journeys. The best fit depends on whether you’re doing ecommerce, SaaS lifecycle marketing, sales outreach, or general CRM automation.

Here are some strong options:

A few that are especially close to what you described:

• Omnisend — probably one of the simplest if you want “draw a flow → add email → wait → send SMS → branch based on behavior.” Its automation editor supports email, SMS, web push, splits, and behavioral triggers. www.omnisend.comtrillet.ai
• Customer.io — better if you need complex logic like: “If user signs up → send email → wait 3 days → if they used feature X send SMS, otherwise send a different email.” www.sequenzy.com
• ActiveCampaign — a good all-around choice for lead nurturing, sales funnels, and CRM-connected sequences.
• Klaviyo — best known for ecommerce flows like abandoned cart, post-purchase, win-back, and VIP campaigns.
• Braze — for larger companies needing sophisticated customer journeys.

If you mean something more like Zapier/n8n-style canvas automation (nodes connected by lines) rather than a marketing automation builder, there are also newer workflow-first tools that combine email/SMS steps visually. trillet.ai

A quick recommendation:

• Small business / agency: ActiveCampaign or Omnisend
• Shopify/ecommerce: Klaviyo or Omnisend
• SaaS onboarding + lifecycle: Customer.io
• Enterprise: Braze
• Sales follow-up sequences: ActiveCampaign or HubSpot

If you tell me your use case (e.g., cold outreach, lead nurturing, ecommerce, SaaS onboarding, appointment reminders), I can narrow it down.

Yes. The category you’re looking for is omnichannel marketing automation / customer journey platforms. Several let you visually build a workflow where email and SMS are just different steps in the same sequence.

Best options

My first choice would be Customer.io if what you're picturing is literally a canvas like:

                ┌─ Email #1
                │
New lead ── Wait 2 days ──┤
                │
                └─ SMS #1
                       │
                   Wait 3 days
                       │
                  Clicked?
                 /        \
               Yes         No
                │           │
             Email #2     SMS #2

Customer.io's Visual Workflow Builder is specifically designed for this. You drag email, SMS, delays, conditions, branches, events, etc. onto a canvas, and email + SMS can live in the same workflow. customer.io

It also has a visual drag-and-drop email editor, so you don't need a separate email-design tool. docs.customer.io

Customer.io Visual Workflow Builder

Klaviyo is probably the strongest alternative if you're doing e-commerce. Its current platform supports multi-step campaigns across email, SMS, push and WhatsApp, with a visual campaign interface. www.klaviyo.com

Klaviyo Omnichannel Marketing

One important distinction

If you mean "I want to visually design the entire customer journey", look at Customer.io / Klaviyo / Braze.

If you mean "I want a simple drag-and-drop automation builder for leads, sales follow-ups, and CRM", ActiveCampaign or HubSpot may be a better fit.

If you tell me what you're trying to automate (e.g. lead nurturing, SaaS onboarding, abandoned cart, appointment reminders, outbound sales), I can narrow it down to the 2–3 platforms that fit best, including pricing and how their workflow editors compare.

Yes. There are several platforms built specifically around this.

Best fits

Customer.io is probably the closest match to what you're describing. Its Journeys product gives you a drag-and-drop canvas where you can visually build sequences with triggers, delays, conditions, branches, and different channels—including email and SMS in the same workflow. customer.iowww.klaviyo.com

Customer.io

ActiveCampaign is another strong choice if you want the workflow to connect closely to a CRM/sales pipeline. Its visual automation builder explicitly supports email and SMS within the same automation. www.activecampaign.com

ActiveCampaign

Klaviyo is especially compelling if this is for an online store. Its Flows builder lets you create cross-channel journeys using email, SMS, and push, with branching based on customer behavior. www.klaviyo.com

Klaviyo

If you're imagining something like this

             New Lead
                │
             Wait 5m
                │
          ┌─────┴─────┐
          │            │
       Email 1      SMS 1
          │            │
        Wait          Wait
        1 day         2 days
          │            │
       Opened?       Replied?
       /     \        /    \
     YES     NO     YES     NO
      │       │      │       │
   Email 2  SMS 2   Stop   SMS 2

Then Customer.io or ActiveCampaign would be my first two to investigate.

If you tell me what you're trying to sell/use the campaigns for (e.g. SaaS leads, real estate leads, e-commerce, appointment booking, cold outreach), I can narrow it down to the 2–3 best platforms and compare pricing, workflow flexibility, SMS capabilities, and ease of use.

Yes. There are several platforms built specifically around visual, drag-and-drop customer journeys where you can mix email and SMS in the same sequence.

Best options

Customer.io is probably the closest match to what you're describing. Its workflow builder is literally a drag-and-drop canvas where you can put email, SMS, delays, conditions, branches, events, segments, A/B tests, and other actions into one journey. customer.io

For example, you could visually build:

             ┌─ Email ── wait 2 days ──┐
Signup ──────┤                          ├─ If purchased → Exit
             └─ SMS ─── wait 1 day ────┘
                         ↓
                    Email #2
                         ↓
                   If clicked?
                    /       \
                  Yes        No
                  ↓           ↓
               SMS #2      Email #3

Klaviyo is especially strong if this is for an online store. Its Flows builder supports cross-channel journeys combining email, SMS, and push, with branching and behavioral triggers. www.klaviyo.com

Brevo is another good option if you want something simpler/less expensive. Its newer automation editor has a drag-and-drop canvas and supports email, SMS, branching, delays, and event-based triggers. help.brevo.com

If you tell me what you're trying to use it for (e.g. lead generation, SaaS onboarding, ecommerce, sales outreach, appointment reminders), I can narrow this down to the 2–3 platforms I'd actually consider, including pricing and how good their visual builder is.

Yes. There are several platforms that do exactly this—visual, drag-and-drop workflows where email and SMS can be mixed into the same sequence.

Best options

Customer.io is probably the closest match to what you're describing. Its workflow builder is literally a visual canvas where you drag in email, SMS, delays, conditions, branches, events, webhooks, etc. customer.io

For example, you could visually build:

New Lead
   ↓
Send Email
   ↓
Wait 2 days
   ↓
Did they open?

  STOP    SMS

Klaviyo is particularly strong if you're selling products online. Its Flow Builder supports email, SMS, and push in a single flow, with branching and behavioral triggers. www.klaviyo.com

ActiveCampaign is another strong choice if you want the workflow tied closely to CRM/sales activity. Its current automation builder explicitly supports building email and SMS campaigns within the same visual workflow. www.activecampaign.com

Omnisend is worth considering if you want something simpler: its no-code editor lets you visually sequence email, SMS, and web push with behavioral branches. www.omnisend.com

If you're thinking about building a platform like this

There's also a distinction worth making: Customer.io/Klaviyo are marketing platforms with visual workflow editors, whereas you could build a more focused product whose core UX is essentially:

"Zapier/Make-style canvas + email/SMS campaign builder."

If that's what you're actually looking for, I can also break down the best existing platforms to use as inspiration, their workflow UX, APIs, pricing, and what it would take to build your own version.

Yes. There are several platforms built specifically around a visual, drag-and-drop journey builder where you can mix email and SMS in the same sequence.

Best options

My first two to look at

Customer.io is probably the closest match if what you're imagining is literally a canvas like:

Trigger → Email → Wait 2 days → SMS → If/else → Email → Wait → SMS

Its workflow builder lets you drag message/action blocks onto a canvas, add delays and branching, and put email and SMS into the same workflow. docs.customer.iowww.klaviyo.com

Customer.io visual workflow builder

Klaviyo is particularly good if you're selling products. Its Flows builder is also drag-and-drop and supports email, SMS, and push in a single flow, with lots of ecommerce triggers such as signup, cart abandonment, purchase, etc. www.klaviyo.com

Klaviyo Flows

If you're building a SaaS/product

I'd lean Customer.io. It is designed around behavioral events and customer journeys rather than primarily ecommerce. You can do things like:

User signs up
      ↓
Wait 1 day
      ↓
Email: Welcome
      ↓
Did they activate?
   ↙          ↘
 YES           NO
 ↓              ↓
Wait 7d       SMS: Need help?
 ↓              ↓
Email: Tips    Wait 2d
 ↓              ↓
Upgrade?      Email: Getting started

Customer.io also supports branching, A/B tests, time windows, webhooks, conversion goals, and other workflow actions. docs.customer.iowww.klaviyo.com

If you tell me what you're trying to automate (e.g. lead nurturing, SaaS onboarding, appointment follow-up, ecommerce, sales outreach), I can narrow this down to the 2–3 best platforms and compare pricing, workflow flexibility, SMS capabilities, and ease of setup.

Yes. There are several platforms built specifically for visual workflow automation where you can drag-and-drop triggers, delays, conditions, emails, and SMS steps into a customer journey.

Here are some of the stronger options:

A few recommendations by use case:

If you want a simple “draw the funnel” builder

• ActiveCampaign — probably the closest match to a marketing automation flowchart:
  • Trigger: “Someone fills out form”
  • Wait: “2 days”
  • Send email
  • If opened → send SMS
  • If clicked → assign sales task

If you run ecommerce

• Klaviyo or Omnisend
  • abandoned cart
  • post-purchase flows
  • VIP/customer segments
  • browse abandonment
  • SMS promotions

Omnisend specifically supports visual workflows with email, SMS, web push, triggers, splits, and A/B testing. www.omnisend.com

If you need complex branching logic

• Customer.io
  • “If user did X, but not Y, within 7 days…”
  • event-based journeys
  • product onboarding
  • lifecycle messaging

It is often chosen for more technical SaaS-style automation. www.sequenzy.com

If you want a CRM + campaigns in one place

• HubSpot
  • contacts
  • pipeline
  • forms
  • email automation
  • sales handoffs

A few newer/smaller tools also focus heavily on the “canvas” experience, such as platforms that let you literally connect blocks like trigger → wait → email → SMS → branch → exit. www.turboworkflow.com

If you tell me your use case (e.g., B2B lead nurture, ecommerce, SaaS onboarding, appointment reminders, real estate, agency clients, etc.) and approximate contacts/month, I can narrow it down.

Yes — there are several platforms built specifically around this.

Best options

Customer.io is probably the closest match to what you're describing. Its Journeys product gives you a drag-and-drop canvas where you can build something like:

                    ┌─ Opened email ──→ Wait 2 days ──→ SMS
                    │
Trigger → Email ────┤
                    │
                    └─ Didn't open ──→ Wait 1 day ──→ Email #2
                                           │
                                           └─ Clicked → Sales notification

You can combine email, SMS, delays, conditions, branching, events, segments, and other actions in the same visual workflow. customer.io

Customer.io Journeys

If you want something more marketing-friendly

ActiveCampaign is worth looking at. Its automation builder is explicitly designed for visually mapping email + SMS journeys, with triggers, actions, conditions, and timing. www.activecampaign.com

ActiveCampaign Automation Builder

For ecommerce, Klaviyo is especially strong: its Flows builder lets you create cross-channel email/SMS/push sequences with a drag-and-drop interface. www.klaviyo.com

Klaviyo Flows

If you're thinking about building a product/platform that does this, rather than looking for a tool to use, that's also a very well-defined product category. I can break down what the underlying architecture/UI would look like and which APIs you'd need for email + SMS.

Yes. There are several platforms built specifically for creating email campaigns + SMS sequences using a visual workflow/journey editor. The best choice depends on whether you’re doing ecommerce, SaaS/lifecycle marketing, lead nurturing, or sales outreach.

Here are some strong options:

A few more specialized options:

• Braze — enterprise customer engagement; very powerful multi-channel orchestration.
• Iterable — large-scale lifecycle marketing and experimentation.
• Delivra — email + SMS automation with visual workflow tools. www.delivra.com

Typical workflows you can build in these tools:

New lead signs up
        ↓
Send welcome email
        ↓
Wait 2 days
        ↓
Did they open?
     ↙       ↘
  Yes         No
  ↓           ↓
Send SMS   Send reminder email
  ↓
Wait 5 days
  ↓
Move to sales sequence

My rough recommendations:

• Shopify/ecommerce: Klaviyo or Omnisend
• B2B lead nurturing: HubSpot or ActiveCampaign
• SaaS onboarding: Customer.io or Braze
• Simple visual builder without enterprise complexity: ActiveCampaign, Omnisend, or Bento

If you mean a “draw boxes and connect arrows like Zapier/n8n, but for marketing sequences” specifically, I’d narrow the list to Customer.io, ActiveCampaign, Omnisend, and Klaviyo.

Yes. Several marketing automation platforms let you build email campaigns + SMS sequences using a visual workflow/journey editor (drag-and-drop nodes, triggers, delays, branches, conditions, etc.). The best fit depends on whether you’re doing ecommerce, SaaS/customer lifecycle, sales outreach, or general marketing.

A few examples of what you can build:

New signup
   ↓
Send welcome email
   ↓
Wait 2 days
   ↓
Did they open?
   ↙          ↘
 Yes           No
 ↓             ↓
Send SMS     Send reminder email
 ↓
Wait 5 days
 ↓
Offer / demo CTA

My shortlist by use case:

• Ecommerce: Klaviyo or Omnisend
• SaaS onboarding / product journeys: Customer.io or Braze
• Sales + CRM automation: ActiveCampaign or HubSpot
• Simple email + SMS sequences without enterprise complexity: Omnisend or Bento

If you mean a true flowchart-style canvas (like Zapier/Node-RED where you literally connect boxes), the strongest options are usually Customer.io, Braze, ActiveCampaign, and Omnisend. bentonow.comwww.omnisend.com

If you tell me whether this is for ecommerce, SaaS, sales outreach, or a newsletter/community, I can narrow it down.

Yes. There are several platforms built specifically around this kind of visual, drag-and-drop customer journey.

Best options

🥇 My first look: ActiveCampaign

ActiveCampaign has a visual automation builder where you can essentially draw:

Trigger → Email → Wait 2 days → Condition → SMS → Wait → Email → Exit

It supports branching based on behavior, and its current platform supports both email and SMS within the same automation. www.activecampaign.com

🧠 If you want really sophisticated workflows: Customer.io

Customer.io is particularly strong if you're thinking in terms of customer journeys rather than traditional email campaigns.

For example:

New Lead
   ↓
Send Email
   ↓
Wait 2 days
   ↓
 ┌───────────────┐
 │ Opened email? │
 └───────┬───────┘
       Yes ↓       ↓ No
      SMS       Send Email
       ↓            ↓
    Wait 3d       Wait 2d
       └──────┬─────┘
              ↓
         Conversion?
          ↙       ↘
        Yes        No
        ↓           ↓
       Exit       SMS

Customer.io explicitly supports drag-and-drop workflows, branching, delays, behavioral triggers, email, SMS, push, and in-app messaging. customer.io

🛍️ If this is for ecommerce: Klaviyo or Omnisend

Klaviyo has visual Flows combining email, SMS, and push in one journey, with behavioral triggers and branching. www.klaviyo.com

Omnisend is another particularly clean option. Its Automation Editor lets you visually combine email, SMS, web push, delays, splits, and behavioral triggers. www.omnisend.com

If you're asking because you want to build a product like this yourself, that's also very feasible—the core UX is essentially a node-based workflow editor + messaging engine + audience/event system. If that's what you're exploring, I can break down what the architecture and UI would look like.

Yes. There are several platforms built specifically around visual, drag-and-drop customer journeys where email and SMS can live in the same sequence.

Best options

Klaviyo is probably the closest match if you mean something like:

Trigger → Email → wait 2 days → check if opened → SMS → wait → check purchase → Email A/B

Its current campaign builder lets you visually orchestrate email, SMS, push, WhatsApp, etc. in one journey. www.klaviyo.com

Klaviyo

Customer.io is particularly strong if you want more sophisticated branching and event-based logic. Its visual builder supports email + SMS, delays, conditional branches, A/B tests, behavioral triggers, and "wait until" conditions. customer.io

Customer.io

And Spur is worth looking at if you specifically want a no-code canvas combining WhatsApp + email + SMS. www.spurnow.com

Spur

If you're building a SaaS/product

I'd narrow it to Customer.io vs Klaviyo:

• Customer.io → better for event-driven product/customer journeys
• Klaviyo → better for ecommerce, leads, purchases, customer profiles, and revenue attribution
• ActiveCampaign → better if the workflow is heavily tied to CRM/sales follow-up

If you tell me what you're trying to automate (e.g. lead nurturing, cold outreach, SaaS onboarding, abandoned cart, appointment reminders), I can give you the 3 best platforms and how their visual builders compare.
