Postmark Email Template Builder

Q: Do Postmark Handlebars variables work?

Yes. Anything you type into a Temway text block — {{name}}, {{delivery.date}}, {{order.id}}, or any Postmark variable — passes through untouched, and Postmark processes it at send time as normal.

Design in Temway, send from Postmark

Temway is a visual email template builder that connects directly to Postmark. Compose a responsive email with drag-and-drop blocks, then push it into your Postmark account as a standard template — ready to call from your application for transactional sends.

If you’ve been searching for a “Postmark template builder” that gives you production-grade responsive HTML without hand-authoring markup, this is it. You design; Postmark keeps doing what it’s good at — fast transactional delivery, bounce handling, and inbound parsing.

Why design in a separate builder?

Postmark is purpose-built for transactional email, and most teams author templates in code via the Templates API. Hand-writing Postmark-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.
Handlebars logic by hand is error-prone — Postmark templates use {{name}} syntax for dynamic content, and pasting it by hand is easy to mistype.
No single source of truth — every transactional template (welcome, reset, receipt) 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 Postmark standard template.

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

How the Postmark integration works

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

Lands as a standard template with a subject line (using your template name as a sensible default — editable inside Postmark) and the rendered HTML as the body.
Authenticates with your Postmark server token via the X-Postmark-Server-Token header.
Client-safe output means the pushed HTML renders consistently across Gmail, Outlook, Apple Mail, and the rest.
Credentials encrypted at rest — your server token is never displayed again after you connect.

Postmark-specific details that just work

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

Handlebars variables pass through. Paste {{name}}, {{delivery.address}}, {{order.total}}, or any Postmark Handlebars syntax into a Temway text block — it renders into the HTML untouched and resolves normally when Postmark sends.
Editable after push. The template lands in Postmark’s Templates list, so you can tweak copy or swap an image inside Postmark between sends.
Design-only by design. Temway never touches your servers, sender signatures, bounce handling, or send configuration. Those stay entirely in Postmark — Temway only creates the template; your application code decides when to fire it.

Start from a Postmark-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 Postmark account.

Frequently asked questions

Do Postmark Handlebars variables work? Yes. Anything you type into a Temway text block — {{name}}, {{delivery.date}}, {{order.id}}, or any Postmark variable — passes through untouched, and Postmark processes it at send time as normal.

One caveat on literal curly braces. Postmark’s template parser treats {{…}} as a variable. If you have legitimate content with literal double-curly braces (a code snippet you want displayed as-is), Postmark may try to interpret it. This is Postmark behavior, not Temway behavior — escape or rephrase the literal braces inside Postmark if you hit it.

Does Temway sync my Postmark servers or sender signatures? No. Temway is design-and-push only. Servers, sender signatures, bounce handling, and send configuration live entirely in Postmark. Temway creates a template; your application code decides who receives it.

What Postmark plan do I need? You need a Postmark server token, available across Postmark plans. Beyond that, send volume depends on your Postmark plan — check Postmark’s current pricing for specifics; that’s a Postmark question, not a Temway one.
