Easy!
Just connect your email inbox by going to Settings > Email Settings and click on the plus button.
Salesflare will now automatically synchronize email signatures to your contacts for every new email that comes in from a contact.
Even better: Salesflare will also go back into the recent future to import more email signatures, so you can have some data to start from.
Note that no email signature detection is 100% perfect:
Email signatures come in many, unpredictable formats. It's free text after all.
Email signatures in image format can not be imported at the moment.
Find any obvious email signature that didn't get imported? Let us know on the chat, so we can use it to improve!
