Let's say I set 3 follow up messages in an autoresponder.
Day 0 - message #1
Day 1 - message #2
Day 2 - message #3
Then, on day 8, I decide to add another message to that sequence:
Day 3 - message #4
Obviously a news subscriber will smoothly receive the whole sequence, but what about the elder one? Would they have a chance to receive the message #4, considering that on their day 3 there were no messages scheduled to be sent?
What is the common habit among the autoresponders?
