Mailtrap Email Template Builder

Design in Temway, send and test from Mailtrap

Temway is a visual email template builder that connects directly to Mailtrap. Compose a responsive email with drag-and-drop blocks, then push it into your Mailtrap account as an HTML template — ready to use in a campaign, test send, or production send.

If you’ve been searching for a “Mailtrap template builder” that gives you production-grade responsive HTML without hand-authoring markup, this is it. You design; Mailtrap keeps doing what it’s good at — email testing, inbox inspection, and reliable delivery.

Why design in a separate builder?

Mailtrap is developer-first — most teams author templates in code or import raw HTML. Hand-writing Mailtrap-ready HTML is where the friction lives:

Responsive columns that drift in Outlook — hand-coded layouts are fragile; a single mistake breaks rendering in Outlook.
No visual editor for layout — Mailtrap’s strength is testing and delivery, not visual email design. Teams end up designing elsewhere and importing.
No single source of truth — every template is authored separately, so brand consistency drifts.
Dark-mode rendering you can’t fully control — logos invert, transparent PNGs get dark halos, brand colors shift.

Every email Temway exports is built to render correctly across Gmail, Outlook, and Apple Mail, with responsive behavior already handled. You compose visually; the output is clean HTML that drops straight into a Mailtrap template — and you can test it in Mailtrap’s own inbox preview before sending for real.

This isn’t about replacing Mailtrap — it’s about giving your team a faster, more reliable way to design the transactional and marketing emails Mailtrap delivers.

How the Mailtrap integration works

Connect your Mailtrap account once from your Temway workspace’s integration settings using your API token. When your email is ready, choose Push to Mailtrap. Temway renders the final, inbox-ready HTML and creates a new template in your Mailtrap account.

Lands as an HTML template under Email Templates — ready to reference for a campaign, test send, or production send.
Category required. Mailtrap’s API requires a category on every template; Temway assigns a default you can rename inside Mailtrap after the push.
Authenticates with your Mailtrap API token via Bearer auth.
Client-safe output means the pushed HTML renders consistently across Gmail, Outlook, Apple Mail, and the rest.
Credentials encrypted at rest — your API token is never displayed again after you connect.

Mailtrap-specific details that just work

Because Temway pushes raw HTML into a Mailtrap template and Mailtrap processes its own variables at send time, a few things work exactly the way Mailtrap users expect:

Personalization variables pass through. Paste any Mailtrap variable syntax into a Temway text block — it renders into the HTML untouched and resolves normally when Mailtrap sends.
Test inside Mailtrap after the push. The template lands ready to send or inspect — open it in Mailtrap’s HTML inspector or run an inbox test before going live.
Design-only by design. Temway never touches your sending domains, suppression lists, or delivery settings. Those stay entirely in Mailtrap — Temway only creates the template; your application code or campaign decides when to fire it.

Start from a Mailtrap-ready template

Don’t begin from a blank canvas. Browse the template gallery for responsive, transactional-friendly starting points — then customize the branding, copy, and layout in Temway before pushing to your Mailtrap account.

Frequently asked questions

Why is a category required? Because Mailtrap’s template API requires a category on every template — it’s a Mailtrap requirement, not a Temway one. Temway assigns a default category on the push so the template saves successfully; you can rename it inside Mailtrap afterward.

Do Mailtrap personalization variables work? Yes. Anything you type into a Temway text block — Mailtrap’s variable syntax — passes through untouched, and Mailtrap processes it at send time as normal.

Does Temway sync my Mailtrap sending domains or suppression lists? No. Temway is design-and-push only. Sending domains, suppression management, inbox testing, and delivery configuration live entirely in Mailtrap. Temway creates a template; your application code or campaign decides who receives it.

What Mailtrap plan do I need? You need a Mailtrap API token, available across Mailtrap plans. Beyond that, send volume and testing features depend on your Mailtrap plan — check Mailtrap’s current pricing for specifics; that’s a Mailtrap question, not a Temway one.
