Mailcheer

Mailcheer is an email platform for developers and small teams. It covers both kinds of email in one workspace: transactional emails sent from your code through a REST API (`POST /api/v1/emails`, idempotency keys, delivery status, webhooks), and newsletters and campaigns built in a block editor with segments, automations, A/B tests, signup forms and open/click statistics. Sending goes through Amazon SES from your own authenticated domain (DKIM, SPF, DMARC). Bounces and spam complaints are added to a suppression list automatically. Mailcheer also ships an MCP server, so AI agents such as Claude Code, ChatGPT or Codex can draft, test and schedule sends on your behalf. API keys carry fixed, per-permission scopes. Servers are in Falkenstein, Germany; emails leave from Amazon's Ireland region. The free Discovery plan includes 3,000 emails a month and unlimited subscribers, no credit card required. Paid plans start at €19/month.
