Burned mailboxes, weeks to recover

A burned domain takes weeks to replace
You find out from the replies
Replies stop on one domain. By the time you check, the mailboxes on it can have been landing in spam for days.
Contributing factors stack up
List quality, volume per mailbox, a shared tenant, a warm-up pool aimed at providers your leads are not on. Each can contribute to a burn, and they usually overlap.
Another warm-up, more money, more waiting
New domains need roughly three weeks of warm-up before they earn their keep. That is three weeks of lower volume on a campaign the client is already paying for.

Replace the mailbox before the burn
Risk Level flags it, a replacement takes over
Risk Level is built from sending data and flags a mailbox ahead of your reply rate. The infrastructure is replaceable, so a flagged mailbox is swapped out and volume holds.

- Backup domains held ready
- Flags on every vendor you use

Teams running outbound on sending.ac
Can confirm. We actually tested them, and performed next to Winnr the best. Good on Yannic Schwock
Setup was fast, DNS and DKIM handled automatically, and each domain runs on its own isolated tenant so a burned domain stays contained.
Btw, you guys have the smoothest UX/UI of all the inbox resellers I’ve purchased from. And I’ve worked with ALL of them.
