Currently doing 1 initial email plus 2 follow-ups, spaced 4 and then 7 days apart. Around 40% of my replies come from the follow-ups, so they clearly matter.
A colleague insists on 4 follow-ups and says the last one gets the most replies. That feels like a good way to get marked as spam and burn the sending domain though.
What cadence do you use, and have you seen deliverability drop from too many follow-ups?
