I would like for HubSpot’s automatic deduplication to account for the fact that email addresses using the @gmail and @googlemail domains are the same email.
Consider notreal@gmail.com and notreal@googlemail.com — no matter which of these you send to, your email will land in the same inbox, so it’s irrelevant which domain format your Gmail contacts use.
Currently, a new contact will be created for each of these and then you have to merge them manually. Frustrating!
