Q3 supporter mailings: the case for staggered despatch
Q3 supporter mailings: the case for staggered despatch. Charities batch-mail. It feels efficient. Print run goes out, postage savings are real, the team breathes out. But staggered despatch — 20% per day over five working days — produces a 38% higher open-rate on the digital follow-up. Because supporters who all open on the same Tuesday morning compete for attention with everything else in their inbox. Cheaper to batch. More effective to stagger. That is a real trade-off, and most charities don't even consider it.
