Enable email validation in Dynamics 365 Sales to remove invalid email addresses from your lead and contact records. You'll reduce email bounce rates, improve engagement, and get a better return on your sellers' time.
Email validation analyses 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
How to enable the feature
Go to App Settings
Click Email Validation
Switch Contacts/Leads On
You can now see the Email symbol is in Red denoting that it’s not a valid email address.
