Reply and bounce rate, per mailbox.
See which mailboxes are slipping. Pause them, run warmup, bring them back.
Lambda Group
The signals you need to act on, per mailbox.
See which mailboxes are generating real replies so you can route your best lists to your best senders.
Track bounce rate at the mailbox level to catch reputation issues before they spread across the rest of your campaigns.
Reply and bounce data updates continuously, so you always see the current state of every mailbox in your account.
When a mailbox starts slipping, pause it from campaigns and run warmup. Reputation rebuilds through real engagement - no hidden auto-pause.
Per-mailbox signals, not blended campaign averages.
SendKit shows reply rate for every mailbox across your campaigns. You can see exactly which mailboxes are generating real engagement and which ones aren't.
Bounce rate is broken out per mailbox, not just per campaign. If one mailbox is bouncing more than the rest, it stands out immediately.
When a mailbox looks unhealthy, pause it from campaigns and run warmup. Reputation rebuilds through real engagement, and the health dashboard shows you when it's safe to send again.
Per-mailbox reply rate and bounce rate let you spot the weak ones without manually checking every account every day.
Reply rate trending down or bounce rate creeping up is the earliest signal that a mailbox is starting to struggle. You see it before it spreads.
See which client mailboxes are performing and which need attention, without hunting through each account individually.
Why per-mailbox visibility matters at scale.
Per-mailbox reply and bounce rate, not just campaign averages
Most platforms show you aggregate campaign metrics but hide per-mailbox data. Without that breakdown, you can't tell which specific mailboxes are healthy and which are dragging your overall numbers down. SendKit surfaces reply rate and bounce rate for every mailbox so you can act on the right signals.
Aggregate numbers hide the real story
Campaign-wide reply rates and bounce rates blend healthy mailboxes with failing ones. A mailbox can be deep in spam while the campaign average still looks fine. SendKit shows per-mailbox reply rate and bounce rate so you can see exactly where the problem is, not a number that averages it out.
Protection and recovery happen in warmup
SendKit doesn't auto-pause mailboxes behind your back. When a mailbox looks unhealthy, you pull it from campaigns and run warmup to rebuild engagement and reputation. Warmup is where recovery actually happens - the health dashboard tells you when to act and when you're back to safe.
Got questions? We've got answers.
No. SendKit shows you reply rate and bounce rate for every mailbox so you can decide when to pull one from campaigns. Automated pausing can mask the underlying issue - visibility lets you act on the signals with full context.
