Latest additions
- Automations: three recipes that write on your behalf. A welcome message on signup, a drip sequence (day 0, day 3, day 7…), a re-engagement for subscribers who did not open a campaign. Nothing sends until you turn the automation on, and no one receives the same message twice.
- A/B tests: two subject lines, or two content variants. A portion of the list you choose receives the sample; after the delay you set, the version with the most opens or clicks goes to the rest. Under thirty recipients per variant, Mailcheer declares no winner.
- Signup forms: a hosted page to share and an HTML snippet to embed on your site. They collect your custom fields, apply tags, and a subscriber enters the list only after confirming. See the Forms page.
- Webhooks: Mailcheer calls your service as soon as an email is delivered, opened, clicked, bounced or reported, and on every subscription or unsubscription. Every call is signed, and Mailcheer retries if your service does not respond.
- Public API: send a transactional email and manage your subscribers, suppression list, campaigns and webhooks from your own code. Each API key carries permissions checked one by one, under Account → API & AI agents. See the reference.
- MCP server: connect Claude Code, ChatGPT, Codex or Cursor to your workspace with one command. Thirteen tools, with the same permissions as the key. Installation guides are on the Agents page.
