Drip programs are automated email campaigns that send a series of messages to prospects based on predefined criteria and triggers. You can pause and resume drip programs at any time. However, when you resume a drip program, it does not start immediately. It takes up to one hour for the drip program to resume sending emails to the prospects in the program. It does not take 5 minutes, one business day, or immediately for the drip program to start after unpausing it. References: Drip Programs, Pause and Resume Drip Programs
