Sequencing vs Drip Campaign?
Drip Campaign: Drip Campaign is a type of automated campaign focused on email, which allows you to send out a series of scheduled and customized emails to segments of your contacts base.
Sequencing: An email sequence is a series of emails automatically sent to specific segments of people on your email list. An email sequence can be trigger-based or time-based.
Drip Campaigning does not not stop when a reply is received for a specific email and the user has to stop it manually. However, Sequencing can end it on the basis of the automations.
