Warm Up Your Mailboxes Before You Scale
Build sending activity gradually, monitor mailbox health, and give new sending accounts time to establish a healthy sending pattern before increasing campaign volume.
Warmup runs separately from your campaign sending.

New Mailboxes Shouldn't Go From Zero to Full Volume.
A new mailbox needs gradual sending activity instead of immediately taking on a large campaign volume.
Gradual Ramp
Start with controlled activity and increase volume over time as mailbox health supports it.
Reputation Protection
Avoid putting unnecessary pressure on a new sending mailbox.
Consistent Sending
Build a more natural sending pattern before increasing campaign activity.

Monitoring
Safety threshold set
Auto-pause on poor health
Stops warmup when configured protection rules are triggered.
Preset examples are illustrative. Actual volume stays bounded by mailbox health, account limits, and available sending capacity.
Warmup Doesn't Steal Your Campaign Numbers
MunchReach keeps warmup activity separate from campaign metrics so you can understand what your mailbox is doing without confusing warmup activity with real campaign performance.

Know When a Mailbox Needs Attention
Health reflects real available signals such as recent sends, delivery failures, bounces, complaints, replies, throttling, and authentication.
Healthy
Signals stable
Warning
Monitor or hold
Action needed
Pause or recover
Authentication is shown when it can be verified; otherwise MunchReach shows that manual verification is required. Mailbox health helps explain current signals—it does not guarantee inbox placement.
Built-In Protection When Something Looks Wrong
Bounce Protection
Detect unusual bounce behavior, suppress hard-bounced addresses, and prevent continued sending when protection rules are triggered.
Complaint Protection
Monitor complaint signals, suppress complained addresses immediately, and protect the mailbox from a risky condition.
Automatic Pause
A mailbox can be paused when configured safety thresholds are reached.
Clear Recovery
See why activity was reduced or paused and what needs attention before the mailbox resumes.
See What Your Mailboxes Are Doing
Monitor warmup volume, health, recent events, and ramp decisions without digging through multiple screens.
Planned and actual mailbox activity
Ramp up
Volume increased after stable activity.
Hold
Volume held while a signal was uncertain.
Recovery
Controlled warmup continued at lower volume.
Manage Every Sending Account From One Workspace
Monitor multiple sending accounts without opening each mailbox individually.
