Can I Send Accredible Emails Through Our Email System?

By default, Accredible sends emails on your behalf. However, you can tell Accredible to send mail through any other SMTP server.

The Benefits

Using another SMTP server will allow you to:

  • Have better delivery results - all emails will come from your server so that you are in control of any settings that can help deliver to your recipients.
  • Have the emails come from your domain address rather than Accredible's -  this is good for branding and will potentially help avoid recipients' spam filters.
  • Still customize your email appearance and templates on Accredible, even though the emails are then outsourced to your server.

The Downside

Accredible won't be able to report email bounces. The email bounce data in our data analytics will no longer be accurate as we will no longer have access to the triggers for this information.

Important Note: SMTP Override Settings is not available on Free Trial accounts.

Set Up SMTP Overrides

  1. Click on 'Emails' at the top of your Accredible dashboard
  2. In the left-hand sidebar menu, click on 'SMTP Overrides'
  3. Fill in the required information for the target SMTP server of your choice and click 'Save'.

You can use the 'Send Test Email' function to ensure that your SMTP overrides are setup correctly.

You may also need to check your target inbox to ensure that SMTP settings are correctly enabled here as well. For more information on how to do this, here are further articles related to lead email providers:

Important Notes

  • 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.


  • In order 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 would recommend checking the number of emails your server allows and issuing credentials in batches to remain under this limit.
