If you are setting up SMTP overrides to a Gmail inbox, be sure to check the following information to ensure that everything is set up on your target inbox.
Configuring Custom SMTP Settings for Gmail

You Will Need to Have 2-Step Verification Enabled for Your Google Account
As of May 2022, Less Secure Apps has been deprecated for Google accounts. This means you cannot use your Google account password for authentication with SMTP.
Once 2-Step Verification is enabled for your Google Account, you must follow these additional steps to complete the SMTP setup for your Accredible account.
- Navigate to your Google Account: App Passwords.
- On the App passwords page, use the drop-down menu to select Mail as the App and Other (Custom name) as the device
- Name your custom device Accredible, then click the Generate button.
- A new app password will be generated for you. Copy this password.
- In your Accredible instance, click Emails at the top of your Accredible dashboard.
- In the left-hand sidebar menu, click on SMTP Overrides.
- Ensure the Sender Details: Email and Authentication: Username matches your Google App's email address. The password will be the App Password you just generated in Step 4.
- The Mail Server section will need to be filled out as follows:
Outgoing Server: smtp.gmail.com
Authentication: Base64 encoded
Save your changes.

- You should avoid using Port 25 if that is an option for your SMTP configuration.
- DKIM or SPF settings you previously configured with Accredible will no longer affect delivery since emails will be sent from your server instead of Accredible's.
- To keep systems healthy and safe, email hosts often limit the number of emails that can be sent in a 24-hour period.
- This means that if you enable SMTP Overrides and issue a large batch of credentials (for example, 10,000), you run the risk of the request timing out and your emails failing to send.
- We recommend checking the number of emails your server allows and issuing credentials in batches to remain under this limit.
