SMTP2GO is an email delivery service that lets customers send email and SMS, manage senders and account settings, and view delivery activity and statistics. It also provides SMTP relay infrastructure and tooling for integrating those capabilities into applications.
SMTP2GO exposes a REST/JSON API, a remote Streamable HTTP MCP server, and SMTP relay access; the API and MCP use SMTP2GO API keys, while SMTP relay uses SMTP user credentials.

Log in to the SMTP2GO App and go to Sending > API Keys. Click Add API Key to create a key, then copy it. SMTP2GO docs note keys have an api- prefix and can be permission-scoped per endpoint.
Log in to the SMTP2GO App and create an SMTP User from the Sending > SMTP Users section described in the SMTP Relay guide. Use the generated SMTP username and password to authenticate to mail.smtp2go.com (or region-specific SMTP hosts).
