Hi @Leroy271,
How are these meetings booked? As far as I know, this currently can’t be done, since there isn’t any way to filter contacts by clicks of specific links in sales emails.
You could however approach this by filtering for contact who have booked a meeting and then also filtering for contacts who have been enrolled in your sequence, see Last sequence enrolled:
(In the sequence field, you have to add the sequence ID which you can find at the end of the URL of a sequence in HubSpot, not the name.)
You can only assume that the meeting was booked through the sequence but you couldn’t be sure.
Best regards!
