Days, not diagrams
Each day shows what goes out. Add a step, move it or change a message in seconds.
Sequences
Sequences you can change while they run
Lay out visits, invitations, messages and waits on a simple day-by-day timeline. Edit it after launch, without pausing and without repeating a step anyone already got.
Edit after launch
Changes apply to contacts who haven't reached that step yet. Nobody gets the same message twice.
Safe sending
A message with an empty variable is never sent. The contact waits with a clear reason and a way to fix it.
