Failing mailboxes get paused before they do damage.
SendKit monitors every mailbox in real time. When bounce rates spike, spam placement climbs, or health drops below safe thresholds, the mailbox gets automatically paused from campaigns. No manual babysitting.

One bad mailbox won't tank your campaign.
Mailboxes that cross dangerous bounce or spam thresholds get paused from campaigns instantly.
Bounce rates, inbox rates, spam rates, and engagement metrics for every mailbox in one view.
No manual monitoring needed. Auto-protection runs 24/7 across your entire mailbox fleet.
Paused mailboxes stay paused until you decide they're ready. Run warmup, check metrics, re-enable on your terms.
Damage control that happens without you.
SendKit monitors bounce rates, spam placement, inbox rates, and engagement metrics for every mailbox in your account.
When a mailbox crosses dangerous thresholds — high bounces, low inbox placement, or reputation signals that indicate trouble — SendKit automatically pauses it from campaign sending.
Paused mailboxes stay paused until you're confident they're healthy again. Run warmup, check the metrics, and re-enable when you're ready.
You can't manually check every mailbox every day. Auto-protection catches the one that's failing before it drags your campaign results down.
A mailbox starts bouncing at 3am. Instead of sending 500 more emails from a dying address, auto-pause stops it immediately.
One client's mailbox goes bad. Auto-protection isolates it instantly so other campaigns keep running clean.
Why auto-pause matters at scale.
Most platforms let bad mailboxes keep sending
On other tools, a failing mailbox keeps blasting emails until you notice and manually pause it. By then, the damage is done. SendKit detects the problem and stops sending from that mailbox automatically.
The cost of one bad mailbox sending unchecked
A single mailbox with high bounces or spam complaints can poison your entire campaign. Every email it sends from a damaged reputation makes the problem worse. Auto-pause cuts the bleeding immediately — the mailbox stops sending campaigns before it drags everything else down.
Full visibility into what went wrong
When a mailbox gets auto-paused, you can see exactly why — bounce rates, spam placement, engagement drops. Use the data to decide whether to run warmup to rebuild reputation, check DNS settings, or retire the mailbox entirely.
