The SMTP settings are stored under the "Settings > SMTP Users" section of the dashboard.
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 now recommend that all members use 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 choose 'Settings' > 'SMTP Users'.
We recommend that you copy and paste your SMTP username and password into your email client software - this will likely resolve any "535 incorrect authentication data" errors.
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, so you will need to use your mailbox provider's IMAP/POP settings for inbound email.
