Three types

Marketing, transactional,
cold.

A template in MailerSpark has a type. The type tells the rest of the system what it's for — including the merge tags available, the suppression behavior, and where it can be used.

  • Marketing
    Newsletters and broadcasts. CAN-SPAM footer required. Suppression honored automatically.
  • Transactional
    Receipts, password resets, system notifications. Open tracking optional. Per-recipient.
  • Cold
    Outreach sequence steps. A/B variants supported. Per-inbox identity.

Storage

HTML source
or builder doc.

Some teams write raw HTML — copy from an existing design, paste a Figma export, or use a tool like Postmark's template language. Other teams prefer the drag-and-drop builder. MailerSpark stores both formats and lets you mix them per template.

  • HTML source
    Edit raw HTML. Merge tags in {{double_braces}}.
  • Builder document
    A JSON description of the drag-and-drop blocks. Edit visually, switch to HTML anytime.

Lifecycle

Duplicate, edit, reuse. That's it.

No template library, no marketplace, no version control. Just the templates you actually use.

Duplicate

Clone any template to make a variant. The original is preserved.

Preview

See the rendered email with sample merge tag data before sending.

Edit

Make changes in place. Both HTML and builder modes preserve your work.

Every plan

Templates are in every plan.

Build, save, and reuse them. The free plan includes 1 marketing template — Starter adds unlimited.
