What is email validation?

Email validation analyzes the primary email address in lead and contact records to identify the ones that can't receive email. You must enable the feature. It's turned off by default.

Email address validation looks for the following issues:

  • Incorrect syntax: An address that doesn't contain both a username and an email domain
  • Disposable domain: An address that contains a known disposable or temporary email domain
  • Test or spam email addresses: An address that contains known indicators of a test or spam address in the email header or metadata, IP address, HTML code of the email, and email content and formatting
  • Expired email addresses: An email account that has expired and can no longer receive or send email
  • Emails that bounce back: An address that can't receive a message for any reason

Sellers can view invalid email addresses on record forms, work list items, and the Up next widget in sales accelerator. More information: Work with invalid email addresses

Difference between Dynamics 365 Sales and Power Apps

The email validation feature in Dynamics 365 Sales and Power Apps works on the same principles. However, there are some differences as listed below:

Scenario Dynamics 365 Sales Power Apps

The feedback is displayed each time the form is loaded.
More information: View invalid email addresses

Also, validations are not performed on addresses that are bulk imported.
Actions Users can mark the invalid email addresses as valid.
More information: Send an email to an invalid address

Both features enabled in an organization Only the primary email addresses of leads and contacts are validated according to the Dynamics 365 Sales implementation. All other email addresses are validated based on the Power Apps implementation.
