Best instantly alternative for appointment setters seeing deliverability drops? My open rates just tanked
Been running 5 domains on instantly for 8 months. Past 3 weeks my open rate went from 45% to under 25%. Support says ''normal fluctuations'' but I ran the same campaigns through MailReach and placement looks fine. So it is either instantly's sending infra or I'm doing something stupid.
Sending 50-80 emails per inbox per day. All domains warmed properly. SPF/DKM/DMARC clean. Using Prospeo for lists. Bounce rae is under 3%.
Before I panic-migrate, I want to know if anyone else is seeing this right now. Is 50-80/day per inbox actually too aggressive? Should I throttle back first or is insantly's deliverability actually tanking?
A buddy mentioned WarmySender for the peer-to-peer warmup and built-in verification. Haven't tested it yet. What is the best instantly alternative you are actually seeing better placement on right now?
