What does Could not deliver mean on a contact?
Emails to that address came back undelivered. Check the spelling, correct the email address on the contact and save it, or ask the person for another address.
When you see Could not deliver beside a contact's email address, emails to that address have bounced: they came back undelivered. The address is usually mistyped, for example example.com written as exmaple.com, or it no longer exists.
Correct the address
- Open the contact and compare the address with the one the person gave you.
- Click the Email field, type the right address and choose Save.
- Once a new address is saved, the label is gone.
If the address is right and still bounces, ask the person for another address, or phone them. Correcting the address clears the label.
