Features

Built for the way you actually work.

Most email builders ship 50 mediocre features. Postern picks three and makes them exceptional. The rest of this page is the supporting cast.

Describe, don’t design.

“Make the CTA orange and add social proof above the footer.” Postern reads your template, applies the change, and shows you the diff before saving.

Beyond the core

The supporting cast.

Here’s what holds the three USPs together — the work you don’t notice when it’s done well.

Template gallery

30 starting points organised by industry. Each one ships with conditional blocks pre-built and AI-friendly structure.

Smart drafting

Headline suggestions, subject-line variants, tone-matched rewrites — handled by the same AI you talk to in the editor.

Brand library

Upload your colours and fonts once. Every email respects them. No more “that doesn’t look like us” feedback rounds.

Integrations everywhere

Mailchimp, Klaviyo, Brevo, SendPulse. Zapier. Webhooks. Export to MJML, HTML, or JSON — your data is never trapped.

Version history + rollback

Auto-save on every change. Restore any version. Compare two versions side-by-side before you swap them.

Multi-language UI

English, Russian, Ukrainian, Spanish, Portuguese-BR. Day-one support — not a Phase-2 afterthought.

How we stack up

Three quick comparisons.

  • Stripo has a thousand templates. Postern has conversational AI and a visual conditional builder. If you outgrew Stripo’s editor, read why teams switch.
  • Beefree nailed the SDK. We layered AI as a chat you keep, not a button you press once.
  • Mailchimp is a great suite. The email builder inside it isn’t the strong part — and you’re locked into the ESP. Postern exports anywhere.

Real workflows

Three workflows we hear about often.

Welcome series automation

Design the flow once. Postern personalises per subscriber. VIP onboarding lands different from regular onboarding — with the same canvas underneath.

Rapid A/B testing

Describe two subject-line variants. Postern drafts both. Send to a slice, measure, mail the winner — finish the loop the same day.

Brand consistency at scale

Marketing and sales both send. Without a brand library, design drift wins. With Postern, one config governs every email — even the ones the intern ships.
