Mailjet
Connect Mailjet with Webflow to automate email campaigns, sync form submissions, and send transactional emails.
How to integrate Mailjet with Webflow
Connect Mailjet with Webflow using third-party automation platforms like Zapier or Make.com, embedded Mailjet subscription forms, or custom API integrations with webhooks. Each method offers different levels of complexity and customization.
The Mailjet API documentation provides endpoint specifications. Use Send API v3.1 for transactional emails and Contact Management API v3 for list operations. Review Webflow's APIs for integration options.
Use third-party automation platforms
Platforms like Zapier, Make.com, and n8n connect Webflow forms to Mailjet without code. Select a Webflow trigger (form submission, new order), configure a Mailjet action (add to list, send email), and the platform handles authentication.
Zapier templates start at $19.99/month for multi-step workflows. Make.com starts at $9/month for 10,000 operations.
Setup: 2–16 hours depending on complexity. Requires Mailjet API credentials and Webflow API token from Site settings > Apps & integrations > API access.
The common workflows include:
- Form submissions → contact creation in Mailjet lists
- New orders → transactional confirmation emails
- CMS item creation → content notifications
- Membership signups → tier-appropriate email sequences
Embed Mailjet subscription forms
Mailjet Form Builder generates embeddable widgets with GDPR compliance options. Customize in the Mailjet dashboard, copy HTML, and add via custom code embed in Webflow.
Setup: 45–90 minutes. Limited design customization compared to native Webflow forms.
Build custom API integrations with webhooks
Configure Webflow webhooks to POST form submissions to your middleware, which processes data and calls Mailjet APIs. Review the REST API introduction for implementation details.
Important: Mailjet's API lacks CORS headers — all requests must route through a backend server, not client-side JavaScript.
Setup: Site settings > Integrations > Webhooks. Configure trigger type and endpoint URL. Use the Mailjet Node.js SDK for simplified integration.
The advanced patterns include:
- Double opt-in: Store pending subscriptions with tokens, send verification via Send API, and complete after validation
- Behavioral segmentation: Score contacts via webhooks, route to lists through ContactData API
- Order confirmations: Parse eCommerce webhooks, send templates via Send API
- CMS-triggered campaigns: Monitor CMS collection changes using the CMS API, send notifications with batch processing
Implementation: 20–60 hours depending on complexity.
What you can build
Build automated email workflows that connect Webflow visitor actions to Mailjet campaigns, from lead capture to post-purchase follow-ups.
- Automated lead nurture sequences: Multi-step campaigns based on form submissions (Mailjet Premium+)
- Post-purchase email systems: Receipts, shipping notifications, delivery confirmations via transactional API
- Automated blog newsletters: Webhooks detect new CMS posts, trigger subscriber emails
- Contact sync between platforms: Keep Webflow form contacts synchronized with Mailjet lists automatically
Frequently asked questions
Use automation platforms like Zapier or Make.com to connect without code — select a Webflow form submission trigger and configure a Mailjet action. Alternatively, configure Webflow webhooks to POST form data to your middleware server, which then calls the Mailjet API.
Yes. When using automation platforms like Zapier or Make.com, you can filter form submissions by form name and route each to different Mailjet lists or trigger different email sequences. Configure your webhook with a
filterparameter specifying the form name, or use conditional logic in your automation platform to check the form name field ("name" property in webhook payload) and execute different actions accordingly.
Yes, best practice is to create subaccounts in Mailjet and generate separate API keys per integration. This limits blast radius if credentials are compromised and allows granular monitoring of which tool sends what emails.
