SMTP.com Setup Tutorial
How to configure your SMTP.com API credentials
Login to your SMTP.com account here
Sender Name
Go to Account > Manage Channels and find the "Name" in the "Active Channel" table that corresponds with your SMTP.com login details.
Access Key
In your SMTP.com account create an API key at Account > Manage API Keys, fill in a name and description and do not set "Expires at" (you can always delete this API Key at any time, if you no longer need it).
Username / Password
The credentials are the same that we use while creating the Channel/Sender.
Host SMTP
For older accounts, the Host SMTP is typically send.smtp.com. For newer Ongage accounts (2025 and on), it is usually send-noip.smtp.com. That said, you should always confirm the correct Host SMTP with your SMTP.com account manager, as configurations may vary.
Return Path
Is optional. By default, it is set to the same as the reply address. If you'd like it to be a different email address, you can set it here. If you're not sure, leave it empty
API Host
Is the type of API connection required for this account on SMTP.com. The default in most cases is https://api.smtp.com/v1/ (Confirm with SMTP.com if any changes)
Warning! Changing the 'Sender Name' on the Ongage platform or on the SMTP platform can result in loss of statistics. Please consult support if such a change is needed.
The current Integration of Ongage into SMTP.com does not include retrieving bounce reasons, as is available with all other SMTP integrations in Ongage.
