It's got to be said - I love Drip! I love the customisation you can add to your email automation with the liquid filters. And it's great to think you've got a whole communication sequence in the bank and working for you. Having said that - some elements can be mind boggling! I recently organised a webinar and wanted to make a workflow for registrants leading up to the event. Drip makes it super easy to add delays between emails, but it doesn't let you add an actual time date.
