Plainmail
A minimalist email management service for users with multiple domains, providing real mailbox accounts and supporting automatic DNS record configuration and the standard IMAP/SMTP protocols.
Timeline (last 90 days)
Plainmail is priced at a flat $5 per month, supporting up to 50 domains, 100 mailboxes, and 25GB of storage.
Plainmail's founder is Joey Dafforn.
Plainmail is positioned as providing real mailboxes for person-to-person email rather than a bulk marketing email platform.
Plainmail claims it will automatically write MX, SPF, DKIM and DMARC records directly on Cloudflare, Vercel or Porkbun, and will check them after writing.
Plainmail's automatic DNS configuration only supports three DNS providers: Cloudflare, Vercel and Porkbun.
The mailboxes created by Plainmail are standard IMAP/SMTP accounts and can be connected directly to standard email clients such as Apple Mail, the Gmail app, Outlook or Thunderbird.
Plainmail provides three entry points for automation and programmatic management: an MCP server, a CLI and an API.
Through Plainmail's MCP server, users can ask Claude to create a mailbox such as hello@yourdomain, with the AI assistant directly triggering the mailbox creation process.
Plainmail is not suitable for teams that need large-scale email blasts or marketing automation, nor for enterprises with complex requirements for email archiving and compliance auditing.
Plainmail's core selling point is packaging the tedious tasks of multi-domain mailbox management into a low-cost, automated process, and its long-term stability depends on the success rate of automatic configuration across various domain environments and the maturity of its MCP integration.
