Your contacts may have multiple email aliases or domains. If a contact has set up email forwarding between their accounts, they can respond to your emails within the same thread but from an alternate email address.
When this happens, Apollo recognizes that the response is part of the same email thread and logs the reply in the Activities section of the original contact's profile.
However, Apollo does not yet recognize the alternate email as a contact. This means that if you search for the email, Apollo prompts you to create a new contact.
Click + Add to create a new contact with this email address.
Or navigate to the contact's profile and replace the original email address. To do so, hover your mouse over the contact's email and click the edit icon.
Update the email address and then click Save.
