Where it falls short
- ·Per-inbox billing still multiplies: 5 inboxes = $95/mo
- ·No inbox placement testing on any tier
- ·Higher volumes need the $59–99/inbox tiers
Our take
Warmup Inbox is one of the fairer per-inbox tools, but the model still scales against you: five Basic inboxes cost $95/month and none of the tiers include placement testing. EmailWarmer covers five inboxes for $19/month flat, placement tests included.
