Retainful gives you three ways to build an email. All three are available for campaigns, automation emails, and saved templates.

​
Choose your editor

​
The drag-and-drop editor

Drag blocks from the sidebar onto the canvas, then click any block to edit its content and style.

​
Available blocks

  • Text — headings and paragraphs with full formatting.
  • Image — upload images or pick from your media library.
  • Button — your call to action; link it to any URL.
  • Divider — visual separation between sections.
  • Coupon — displays a discount code, including unique codes generated by automations.
  • Product — pulls real products from your connected store, with image, name, and price. Choose products manually or use a dynamic feed (best sellers, newest, recently viewed).
  • Custom HTML — embed your own HTML inside an otherwise visual email.

​
Working faster

  • Auto-save — the editor saves as you work; if your browser crashes, you can restore your progress.
  • Universal blocks — save a block (like your header or footer) once and reuse it across emails.
  • Personalization — insert merge tags from the toolbar; see Personalization.
  • Preview — check the desktop and mobile rendering before sending, and use web view to see the email as a standalone page.

​
The rich text editor

A focused writing surface with text formatting, links, images, and merge tags. Emails built here tend to feel more personal — great for founder notes and plain-text style announcements, which often get better engagement than heavily designed emails.

​
The HTML editor

Paste or write complete HTML email markup. You’re responsible for email-client compatibility (tables, inline styles — the usual email quirks). Merge tags work in HTML too.
Email clients are far stricter than web browsers. If you hand-code, test in multiple clients — what works in Chrome may break in Outlook.

​
Save and reuse templates

Any design can be saved as a template under Templates:
  • Build a branded base template once — logo, colors, footer — and start every campaign from it.
  • Templates are shared across campaigns and automations, so your branding stays consistent everywhere.
  • Duplicate a template to iterate on a new version without touching the original.
