You built your app with Thunkable because you wanted block-based development like Scratch for real mobile apps. Direct App Store and Play Store publishing, OpenAI integration, and visual programming make mobile development accessible. Now you need email that matches your visual workflow.

Thunkable's block-based approach means you prefer visual tools. Your email platform should have drag-and-drop builders, visual automation, and minimal code. The best fit works like Thunkable: visual logic for complex outcomes. Understanding what email sequences are will help you design automation that engages your mobile app users.

This guide covers 10 email marketing tools that work with Thunkable applications. I prioritized platforms with visual builders that match Thunkable's philosophy. If you are using a different no-code mobile tool, check out our guides for Adalo, FlutterFlow, or Rork.

1. Sequenzy

Price: Free (100 subscribers) / $49/mo at 10,000 subscribers. Transactional emails included at no extra cost.

Thunkable's block-based approach means you want visual tools. Sequenzy's drag-and-drop email editor and visual sequence builder work without code. Build email automation like you build Thunkable apps: visually, with logical flow, and without writing a single line of code.

Drag-and-drop sequence builder creates onboarding flows, engagement campaigns, and re-activation sequences without code. AI generates complete campaigns from natural language descriptions. Describe what your welcome email sequence should accomplish, and Sequenzy builds the complete flow with content, timing, and conditional logic.

At $49/mo for 10k subscribers, it is 55% cheaper than Mailchimp and 67% cheaper than ActiveCampaign. Revenue attribution shows which sequences drive conversions. If your Thunkable app uses Stripe for payments, Sequenzy's OAuth integration syncs subscription data for plan-based segmentation.

Sequenzy handles both transactional and marketing email. Unified platform for password resets AND nurture campaigns. This is especially important for mobile apps where you need verification emails to work alongside engagement campaigns.

Integrate via API blocks in Thunkable or through your backend. Thunkable's Web API component sends HTTP requests to Sequenzy's endpoint when users take actions in your app. The setup maps directly to Thunkable's visual block system.

The visual approach extends to analytics. See which emails perform, which sequences convert, and where users drop off, all in a visual dashboard that matches the intuitive approach Thunkable builders expect.

Where it falls short: No Thunkable-specific integration or marketplace component. Requires Web API component setup. No push notifications, so you need a separate tool for real-time mobile engagement.

Best for: No-code builders who want visual email automation that matches Thunkable's philosophy. Built for founders and indie hackers who think visually.

2. Mailchimp

Price: From $13/mo / ~$110-$135/mo at 10,000 subscribers

Mailchimp is familiar. Most founders have used it. The visual editor and drag-and-drop email builder are intuitive. With 300+ integrations and extensive template library, Mailchimp offers a safe starting point.

The Customer Journey Builder provides visual automation for common flows: welcome series, re-engagement, and activity-based triggers. The interface is well-established, meaning plenty of tutorials and community support exist.

Integration with Thunkable requires Zapier or custom Web API blocks. Zapier connects Thunkable events to Mailchimp audience operations without code.

Where it falls short: Expensive at scale. At 10,000 subscribers, you are paying $110-$135/mo, nearly three times Sequenzy's price. Not mobile-focused. See our Sequenzy vs Mailchimp comparison for a detailed breakdown. Lacks SaaS-specific features.

Best for: Thunkable builders familiar with Mailchimp who want a known quantity.

3. MailerLite

Price: Free (1,000 subscribers) / ~$50/mo at 10,000

MailerLite offers an excellent visual editor with landing pages included on all plans. The free tier includes 1,000 subscribers and 12,000 monthly emails. The drag-and-drop builder produces clean emails with pre-built content blocks.

Landing pages and signup forms complement Thunkable apps that need a marketing presence. If your app needs a waitlist page, marketing site, or signup form, MailerLite includes these without additional tools.

Automation features cover welcome sequences, time-based triggers, and engagement-based branching. A/B testing optimizes subject lines and content on paid plans.

Where it falls short: Not mobile-focused. No transactional email support, requiring a separate tool for auth emails. Integration with Thunkable requires Zapier, adding a dependency.

Best for: Thunkable builders who need visual email building with landing pages. Good for pre-launch marketing alongside your mobile app.

4. SendGrid

Price: Free (100 emails/day) / $20-$90/mo at scale

SendGrid works via API blocks in Thunkable. The Web API component calls SendGrid's REST API to send emails. Enterprise infrastructure handles high volumes reliably.

Thunkable's block system maps well to API calls. Configure the endpoint URL, headers, and body using Thunkable's visual blocks, then trigger sends when users take actions.

Dynamic templates support variable substitution. Pass user data from your Thunkable app to personalize emails.

Where it falls short: The visual email builder is basic. Marketing automation features are limited. Not designed for no-code users, so documentation assumes developer knowledge.

Best for: Thunkable apps needing reliable transactional email via API blocks. Good for apps with high-volume sending needs.

5. Brevo

Price: Free (300 emails/day) / $25/mo at 20,000 emails

Brevo offers a visual builder plus SMS capability. For mobile apps, SMS adds a valuable engagement channel. The free tier includes 300 emails per day with unlimited contacts.

Multi-channel support means email for detailed content and SMS for time-sensitive notifications, managed from one dashboard. WhatsApp is also available in supported markets.

The automation builder supports basic workflows with email and SMS steps. Volume-based pricing can be cheaper than subscriber-based models for apps with large but infrequently emailed lists.

Where it falls short: Mixed deliverability reputation. The interface feels dated compared to modern tools. The free tier's daily limit restricts campaign sends.

Best for: Budget-conscious Thunkable builders who need email plus SMS for their mobile app users.

6. EmailOctopus

Price: Free (2,500 subscribers) / ~$36/mo at 10,000

EmailOctopus offers the most generous free tier among email marketing tools. 2,500 subscribers and 10,000 monthly emails on the free plan. The visual editor is simple and functional.

For Thunkable MVPs in validation, 2,500 free subscribers is substantial. Test your email strategy with a real audience before paying for a platform.

Landing pages are included on all plans. Campaign creation is straightforward without unnecessary complexity.

Where it falls short: Basic automation limited to welcome sequences and time-based follow-ups. No transactional email. Smaller platform with fewer integrations and community resources.

Best for: Budget-priority Thunkable builders. The generous free tier is ideal for testing email with your mobile app's early users.

7. Customer.io

Price: From $100/mo for up to 5,000 profiles

Customer.io offers a visual workflow builder for sophisticated behavioral automation. Track user events and trigger multi-channel campaigns based on behavior patterns. The workflow canvas handles complex branching, A/B testing, and conditional paths.

Multi-channel support includes email, push, SMS, and in-app messages. For mobile apps that need coordinated messaging across channels, Customer.io orchestrates everything from one platform.

Liquid templating enables deep personalization. Predictive audiences identify at-risk users for proactive engagement.

Where it falls short: Expensive at $100/mo minimum. The learning curve is steep. Integration with Thunkable requires backend development or Zapier. May be overkill for simple email needs.

Best for: Thunkable apps with budget for sophisticated behavioral automation and multi-channel messaging.

8. MagicBell

Price: From $99/mo

MagicBell handles in-app notifications plus email. If your Thunkable app needs a notification center (bell icon with recent notifications), MagicBell provides the infrastructure and UI components.

The SDK works with mobile apps. Notification preferences let users control their channels. Email serves as a fallback when users are not active in the app.

Where it falls short: Email is secondary to notifications. Marketing automation is limited. At $99/mo, it is expensive for email alone. Best justified when the notification center is a core feature.

Best for: Thunkable apps that need an in-app notification center with email as a backup channel.

9. ActiveCampaign

Price: From $29/mo for 1,000 contacts

ActiveCampaign offers a visual automation builder with CRM. The automation canvas supports conditional logic, wait steps, goals, and scoring. For Thunkable apps with a sales or client management component, the CRM tracks deals alongside email engagement.

Lead scoring assigns points based on engagement, identifying your most active users. Integration with Thunkable happens through Zapier or backend API calls.

Where it falls short: Can get expensive beyond 1,000 contacts. The interface can feel overwhelming with all the CRM features. Not mobile-focused. Transactional email requires the Postmark add-on.

Best for: Thunkable apps with sales teams needing CRM alongside email marketing.

10. Sender

Price: Free (2,500 subscribers) / $8/mo

Sender offers all automation features on the free plan, which is unusual. Most platforms restrict automation to paid tiers. The free plan includes 2,500 subscribers and 15,000 monthly emails with full automation access.

The visual builder is functional. Automation covers welcome sequences, triggers, and conditional paths. At $8/mo for paid plans, pricing is very competitive.

Where it falls short: Smaller platform with less brand recognition. Fewer integrations. No transactional email support.

Best for: Thunkable builders wanting maximum features for free. The automation-included free plan is unique among email platforms.

Integration Patterns for Thunkable

Web API component

Thunkable's Web API component makes HTTP requests to email platform APIs. Configure the component with your endpoint URL, headers (including API key), and request body. Call the component from your app's logic blocks when events occur.

This is the most direct integration method. When a user signs up, taps a button, or completes an action, your Thunkable blocks trigger the Web API component to call your email platform.

API blocks with data

Thunkable can pass data from your app to the API call. User email, name, plan type, and other attributes flow from your app's variables into the request body. This enables personalized email triggers based on in-app context.

Map Thunkable variables to the JSON body fields your email platform expects. Most platforms need at minimum an email address in the request body.

Backend integration

If your Thunkable app uses a backend (Firebase, Xano, Airtable), route email calls through your backend. This keeps API keys server-side (more secure) and enables complex logic before sending.

Your Thunkable app calls your backend, your backend calls the email platform. This adds a layer but improves security and flexibility.

Zapier connection

Thunkable can trigger Zapier webhooks. Zapier then calls your email platform. This requires no API configuration in Thunkable beyond a webhook URL. Zapier handles authentication, data mapping, and error handling for your email platform.

How to Choose the Right Tool

Visual-first automation: Sequenzy's visual builder matches Thunkable's philosophy. Build automated email sequences with drag-and-drop, just like you build your app.

Budget validation: EmailOctopus (2,500 free subscribers) or Sender (2,500 free subscribers with automation). See our free email marketing tools for startups guide.

Multi-channel mobile: Customer.io for email, push, SMS from one platform. Or pair Sequenzy (email) with OneSignal (push) for best-of-breed.

Familiar and safe: Mailchimp if you have used it before and want a known quantity.

Build vs. buy: For no-code builders, the answer is always buy. The build vs. buy email infrastructure decision is clear when you are building with Thunkable. Focus on your app, not email delivery.

Frequently Asked Questions

How do I send emails from a Thunkable app?

Use Thunkable's Web API component to call your email platform's REST API. Configure the endpoint URL, add your API key in the headers, and include user data in the request body. Trigger the component from your app's logic blocks when events occur (sign up, purchase, milestone).

Can I trigger emails based on in-app actions?

Yes. When users complete actions in your Thunkable app, your logic blocks trigger the Web API component to call your email platform. This can add subscribers, trigger sequences, or send individual transactional emails.

Do I need push notifications alongside email for a Thunkable app?

For most mobile apps, yes. Email handles account-related messaging (receipts, digests, security). Push handles real-time engagement (new messages, activity alerts). Customer.io handles both. Alternatively, pair Sequenzy (email) with a push service.

What is the best free email tool for a Thunkable MVP?

EmailOctopus (2,500 subscribers) and Sender (2,500 subscribers with automation) offer the largest free tiers. Sequenzy's free tier is smaller (100 subscribers) but includes full features including AI sequence generation. Choose based on whether you need subscriber volume or feature depth.

How do I set up welcome emails for my Thunkable app?

Create a welcome email sequence in your email platform. Add Web API component blocks that fire when users sign up. The API call enrolls the new user in your welcome sequence. Sequenzy's AI can generate the sequence content from a description of your app.

Should I use one tool for transactional and marketing email?

Using one tool simplifies management. Sequenzy handles both transactional and marketing email in one platform. For Thunkable builders who value simplicity, this avoids managing two separate services.

Is it safe to put my API key in Thunkable blocks?

Thunkable's Web API component stores credentials on the server side, not in the exported app code. However, for maximum security, route API calls through a backend (Firebase, Xano) rather than calling email APIs directly from the client.

The Bottom Line

For Thunkable apps, Sequenzy matches the visual philosophy with drag-and-drop automation and AI-powered email sequences. The combination of transactional and marketing email in one platform simplifies the stack for no-code mobile builders. For familiarity, Mailchimp connects through Zapier. For budget with landing pages, MailerLite.
