SMTP2GO
Managed SMTP relay and an email API for outbound application messages. Delivery webhooks report sent-mail outcomes, not an incoming mailbox.
Start with the first guide, then choose a sending, receiving, or feedback task. Each walkthrough identifies permissions, operational checks, and the boundary between the service and MailKite. Refer to the official SMTP2GO documentation for current platform requirements.
Explore the guides
Prepare an SMTP2GO sender and application credential
Verify the SMTP2GO sending identity and distinguish API keys from SMTP users before connecting an application.
Send one message through SMTP2GO's email API
Use SMTP2GO's standard-email model and inspect succeeded, failed, failures, and email identity instead of only HTTP success.
Track SMTP2GO delivery feedback without inventing an inbox
Configure outbound event webhooks, correlate message outcomes, and keep reply receiving as a separate infrastructure choice.
