Your SMTP username is the email address you use for your Mailpro account. Your SMTP password is the same password you use to log in to Mailpro. If you change your Mailpro login password, your SMTP password is updated automatically.

Where to find your SMTP credentials

  • SMTP username: your Mailpro account email (e.g., name@company.com).
  • SMTP password: your current Mailpro login password.
  • Server, ports & security: see full settings on our Mailpro SMTP page.

Reset or update your SMTP password

If you’ve forgotten your password or need to change it, use the Forgot Password link on the Mailpro login page. Once your account password changes, your SMTP password changes too—no extra steps required.

Troubleshooting “Authentication failed”

  • Check the email: make sure you’re using the exact Mailpro account email as the SMTP username.
  • Re-enter the password: if you recently changed it, update the password in your email client/app.
  • Verify server/port/TLS: compare your client settings with the values on /smtp/.
  • Lockouts: too many failed attempts? Wait a few minutes, then try again with the correct credentials.

Tip: Use a strong, unique password for your Mailpro account to keep your SMTP access secure.
