How to fix an outbound system that stopped getting replies
When replies dry up, work through these checks in order.
Replies do not stop for no reason. Usually one thing changed.
Check in this order
- Did your emails land in spam? Test a few.
- Did your list quality slip?
- Did your message get stale?
- Did your volume jump?
- Did a domain or inbox get flagged?
Change one thing at a time
Otherwise you will not know what worked.
