Introduction
This article shows the steps required to integrate Gravity SMTP on your website with the SparkPost email service.

Integration Steps
To allow Gravity SMTP to send messages from your website via the SparkPost service, you will need to complete the following steps:
- Login to your SparkPost account.
- Verify your domain in SparkPost.
Adding a verified domain to your SparkPost account is required to prove ownership of the email address and domain used for outgoing messages. You must complete this step before configuring the SparkPost Integration within Gravity SMTP. Refer to this help guide for instructions on how to complete this step. - Obtain your SparkPost API key.
This will be required in settings to create the link between SparkPost and your website via Gravity SMTP. Refer to this help guide for instructions on how to find that API key in your SparkPost account. - Complete the Gravity SMTP Settings screen.
Go to Gravity SMTP → Settings → Integrations and click the settings cog on the SparkPost card. This will open a pop-up modal with all the fields required for SMTP to connect with SparkPost. See this help guide for a description of these settings. - Click the “Save Changes” button.
After saving, you will be returned to the Settings card page, and the Configured text should appear at the bottom of the SparkPost settings card. If your settings card still shows “Not Configured,” check your settings and the steps above to ensure everything has been completed.

- Enable the integration using the on-off toggle (if you are ready to use it).
Click the toggle on the settings card to turn on SparkPost integration. This will show SparkPost as Connected. You can then test using the Gravity SMTP “Send a Test” Tool.
