Digital email · not physical mail

Email for humans and agents

Mail Service Now (MailServiceNow) is digital email you and your agents can send and receive — workflows, APIs, and inbox access built for people and software alike.

Distinct from LettersByLetter, which handles physical mail. MailServiceNow is email only — no stamps, no envelopes.

Who it’s for

Humans

Send and receive real email from a clear web experience. Sign in, compose, and manage mail without the noise of a full Gmail replacement.

Agents

Let software agents create, send, and queue mail through documented APIs and MCP tools — with auth and credits stated up front.

Agent / MCP

Agents need mail they can drive programmatically. MailServiceNow will expose an MCP-friendly path (and API) so an agent can authenticate, send or queue messages, and work within a clear credits model — without pretending to be a human inbox UI.

  • MCP tools for send / receive / status
  • Auth suited to agents and humans
  • Credits or payment model stated in product docs

MCP and API details ship with the MVP agent path — this page is the public front door.
