From the 'Contacts' list, you can easily find all the Contacts in the system who have invalid email addresses. If you have email notifications turned off, you may want to do this to find Contacts with these errors. It's also handy if you just have a lot of invalid email addresses to deal with.
To filter for invalid emails addresses:
- Go to Contacts then All Contacts
- Click Filter Contacts at the top
- Click the Advanced button, then Add Criteria
- Enter the details in the screenshot below into the drop down fields
- Click Filter
Rex will now display a list of Contacts with invalid email addresses.
