SMTP2GO is a cloud-based email delivery service that ensures reliable inbox placement with built-in analytics and automatic failover.

Integration Steps
To allow Gravity SMTP to send messages from your website via the SMTP2GO service, you will need to complete the following steps:
- Create a SMTP2GO account.
- Authenticate a domain as a Verified Sender in SMTP2GO.
Adding a verified sender to your SMTP2GO account is required to prove ownership of the email address and domain used for outgoing messages. You must complete this step before configuring the SMTP2GO Integration within Gravity SMTP. Refer to this help guide for instructions on how to complete this step. - Obtain your SMTP2GO API key.
This will be required in the settings to create the link between SMTP2GO and your website via Gravity SMTP. Refer to this help guide for instructions on how to find that API key in your SMTP2GO account. - Complete the Gravity SMTP Settings screen.
Go to Gravity SMTP → Settings → Integrations and click the + icon. From the list of available integrations, search and select SMTP2GO. This will add it to your integrations and display its settings fields, which you’ll need to complete to finish setup. See this help guide for a description of these settings. - Click the “Save Changes” button.
After saving, you’ll return to the Settings card page, where the new integration card will appear in the list. You can then test using the Gravity SMTP “Send a Test” Tool.
Once the integration is set up, it will be ready for use. You can verify the connection with a test email and send it through SMTP2GO when needed.
