Mailjet Email Template Builder

Design in Temway, send from Mailjet

Temway is a visual email template builder that connects directly to Mailjet. Compose a responsive email with drag-and-drop blocks, then push it into your Mailjet account as a template with your HTML attached — ready to drop into any campaign or transactional send.

If you’ve been searching for a “Mailjet template builder” that gives you tighter layout control than Mailjet’s native editor without hand-authoring markup, this is it. You design; Mailjet keeps doing what it’s good at — contact management, segmentation, and delivery.

Why design in a separate builder?

Mailjet’s drag-and-drop editor is functional, but teams running a regular cadence of campaigns and transactional sends tend to hit the same walls:

Responsive columns that drift in Outlook — Mailjet’s column stacking can render unevenly in Outlook, where older rendering quirks are still a fact of life.
HTML block limitations — Mailjet’s full-HTML mode is fiddly, and the shell-vs-content split in the API makes hand-managed templates easy to break.
No single source of truth — every campaign and transactional email starts from scratch, so brand consistency drifts over time.
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 Mailjet template.

This isn’t about replacing Mailjet — it’s about giving your team a faster, more reliable way to design the emails your Mailjet campaigns send.

How the Mailjet integration works

Connect your Mailjet account once from your Temway workspace’s integration settings. Mailjet authenticates with an API key + secret key pair (not a single token) — you paste both as <apiKey>:<secretKey> into the secret field. When your email is ready, choose Push to Mailjet. Temway renders the final, inbox-ready HTML and creates a new template in your Mailjet account, attaching the HTML as the template’s content.

Lands as a template with HTML content attached — ready to drop into any campaign or transactional send.
Two-step push, fully handled. Mailjet splits a template into a metadata shell and a separate content resource. Temway handles both steps in one push so you don’t have to.
Authenticates with your Mailjet API key pair via Basic auth.
Client-safe output means the pushed HTML renders consistently across Gmail, Outlook, Apple Mail, and the rest.
Credentials encrypted at rest — your API key pair is never displayed again after you connect.

Mailjet-specific details that just work

Because Temway pushes raw HTML into a Mailjet template’s content resource and Mailjet processes its own tags at send time, a few things work exactly the way Mailjet users expect:

Personalization and variable tags pass through. Paste any Mailjet variable syntax into a Temway text block — it renders into the HTML untouched and resolves normally when Mailjet sends.
Editable after push. The template lands in Mailjet’s templates list with the HTML attached, so you can open it in Mailjet’s editor for last-minute tweaks between sends.
Design-only by design. Temway never touches your contacts, lists, segments, or send settings. Those stay entirely in Mailjet — Temway only creates the template; you decide who receives it.

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

Frequently asked questions

Why does the connect form ask for “API key and secret key separated by a colon”? Mailjet uses an asymmetric key pair (an API key plus a secret key) for authentication — both are required, and a single token isn’t enough. Paste them together as <apiKey>:<secretKey> into the secret field; Temway splits them and uses both for Basic auth.

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

Does Temway sync my Mailjet contacts or lists? No. Temway is design-and-push only. Contacts, lists, segments, and send settings live entirely in Mailjet. Temway creates a template with HTML attached; you decide who receives the campaign.

What Mailjet plan do I need? You need a Mailjet API key and secret key pair, available across Mailjet plans. Beyond that, send volume and contact limits depend on your Mailjet plan — check Mailjet’s current pricing for specifics; that’s a Mailjet question, not a Temway one.

Get started

Connect Mailjet from your workspace integration settings (paste your key pair as key:secret), then push your first email. The ESP integrations documentation covers the full walkthrough.
