Updated over 2 months ago

Connecting your mailbox via SMTP ensures smooth email communication through OttoMatey. For some email providers, setting up an SMTP connection is a necessary step before integrating your mailbox natively. Follow this guide to get started quickly and efficiently.


What Is SMTP?

SMTP (Simple Mail Transfer Protocol) is the standard protocol for sending emails. By connecting your mailbox via SMTP, you ensure secure and reliable email delivery directly from your email service provider.

Before You Begin

You’ll need the following:

  • SMTP and IMAP server details (e.g., smtp.example.com, imap.example.com).

  • Your email address and password.

    • Some providers require an app-specific password.

  • Correct SMTP/IMAP port numbers (e.g., 587 for TLS or 465 for SSL).

  • Authentication method (e.g., SSL or TLS).

If you don’t have this information, contact your email provider or refer to the list of popular email providers below.
