MailerSend Email Template Builder

Design in Temway, send from MailerSend

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

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

Why design in a separate builder?

MailerSend is developer-first — most teams author templates in code or via the API. Hand-writing MailerSend-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.
Plaintext version by hand is tedious — MailerSend expects both an HTML and a plaintext body, and producing both manually doubles the work.
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 MailerSend template — and MailerSend auto-generates the matching plaintext version for you.

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

How the MailerSend integration works

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

Lands as a reusable HTML template — ready to reference by template ID from your application code or marketing send.
Plaintext auto-generated. MailerSend derives the plaintext version from your pushed HTML, so you don’t have to author a second body.
Authenticates with your MailerSend 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.

MailerSend-specific details that just work

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

Personalization tokens pass through. Paste any MailerSend variable syntax into a Temway text block — it renders into the HTML untouched and resolves normally when MailerSend sends.
Plaintext handled for you. Push HTML once; MailerSend’s auto-generation produces the plain-text alternative subscribers see in plain-text-only clients.
Design-only by design. Temway never touches your domains, suppression list, inbound routing, or send configuration. Those stay entirely in MailerSend — Temway only creates the template; your application code decides when to fire it.

Start from a MailerSend-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 MailerSend account.

Frequently asked questions

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

What about the plaintext version? You don’t need to write one. MailerSend auto-generates a plaintext version from the HTML Temway pushes. If you’d rather hand-write it, you can edit the plaintext body inside MailerSend after the push.

Does Temway sync my MailerSend domains or suppression list? No. Temway is design-and-push only. Domains, suppression management, inbound routing, and send configuration live entirely in MailerSend. Temway creates a template; your application code decides who receives it.

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