The SMTP settings are stored under the "Sending > SMTP Users" section of the dashboard.
SMTP server: mail.smtp2go.com
The following SMTP ports are available:
TLS or no encryption >> available on ports 25, 2525, 8025, 587 and 80.
SSL >> available on ports 465, 8465 and 443.
To see your SMTP username and password you will need to log in to your SMTP2GO account and go to the 'Sending > SMTP Users' page.
Note: We recommend that you copy and paste your SMTP username and password into your email client software. If incorrect credentials are entered, you will encounter the "535 incorrect authentication data" error.
If your software does not allow you to enter a username and password for authentication, view our Alternatives to SMTP Authentication article covering IP Authentication and Address Authentication (available to paid plans).
If your software requires an IP address to connect to instead of the hostnames we offer, please see our available options listed in the Connecting to an IP Address article.

You do not need to add, edit, or update MX records to use SMTP2GO. You do, however, need to have MX records in place for your incoming mailbox service.
SMTP2GO provides outbound SMTP settings only, so you will need to use your mailbox provider's IMAP/POP settings for inbound email.
Note: If you have previously been advised to use either smtp2go.com or smtpcorp.com as your SMTP server, you may find that some devices (e.g. routers from Netgear) are unable to send due to the lack of a subdomain. We highly recommend updating to: mail.smtp2go.com
We have an extensive list of common setup guides that can also be helpful.
Alternatively, the API can be used for sending and account management, with the full documentation here.
