If an email has been sent to a contact that is not in the system, yet the email includes the attach+'yourCRMnamefirstname.lastname@example.org email address, the email is received and logged by YapCRM servers. The email address then appears on the Attach Emails Failed home panel.
To add the Attach Emails Failed home panel, please see our Setting Home panels guide.
From the Attach Emails Failed home panel, you can see the number of emails sent to that address. Click the + (Fig.1) to create a new contact pre-populated with the email address. Enter any other relevant information and click Save. Once saved, the emails should appear on the Email tab of the new contact.
If the email address is not relevant, click the circle icon to remove the email address from the home panel - this email address will then never appear again.
