If you’re scaling beyond 10 inboxes, TrulyInbox won’t hold up.

2. Inframail – Good TrulyInbox Alternative for Bulk Inbox Creation
When I looked at user feedback for TrulyInbox alternatives that focus on speed and volume, Inframail consistently showed up in reviews and discussions.
Most said TrulyInbox started becoming unstable after 12 inboxes. Manual DNS setups and tracking became a bottleneck.
Inframail, on the other hand, offered a way to create unlimited inboxes under a flat-rate plan, with no extra charges or restrictions.
