Bad campaigns stop
before your domains suffer.
Deliveryman watches bounces, complaints, spam rates and blacklists on every running campaign, and pauses or cancels it when something goes wrong.
Clear limits, applied for you.
Every running campaign is checked against the same rules. When one is crossed, Deliveryman acts first and tells you why.
- Cancelled
Bounce rate above 5%
Usually a list problem. Stopping early keeps it from becoming a domain problem.
- Cancelled
High complaint rate
Too many recipients marking your emails as spam.
- Alert sent
Spam rate crosses 0.3%
You hear about it immediately, so you can fix the copy or the list.
- Paused
High-severity blacklist listing
Campaigns using that domain stop, and you get an urgent alert.
- Alert sent
Moderate-severity blacklist listing
Typically ignored by major ESPs, so sending continues.
- Paused
Plan sends run out
Picks up again on its own when your sends replenish.

What each check
is looking for.
Each limit protects something providers judge you on. Here's what they mean, and how to stay well clear of them.
Bounce rate
The share of emails rejected because the address doesn't exist or the server refused it.
Stay clear: Verify your list before it reaches a campaign.
Email verificationSpam rate
The share of your emails reported as spam. Gmail asks bulk senders to stay below 0.3%.
Stay clear: Fix the copy or the list as soon as the alert arrives.
Content spam checkBlacklists
Public lists of domains reported for spam. High-severity lists are the ones major providers check.
Stay clear: Keep bounces and complaints low, and get delisted fast if it happens.
Blacklist monitoringWhy automatic protection beats watching dashboards
Without guardrails, a bad list or a blacklisted domain keeps sending until someone notices. In Deliveryman, the campaign stops on its own.

Frequently Asked Questions
What does campaign protection watch?
Bounce rate, complaint rate and spam rate on every running campaign, plus the blacklist status of the domains it sends from. It runs automatically, so there is nothing to set up.
What happens if my bounce rate goes above 5%?
The campaign is cancelled automatically, the same as with a high complaint rate. A high bounce rate usually points to a list problem, and stopping early protects your domains and mailboxes.
Why was my campaign paused?
Either one of its sending domains was listed on a high-severity blacklist, or your plan ran out of sends. Blacklist pauses come with an alert and a removal guide. Plan-limit pauses resume automatically when your sends replenish.
Can I resume a paused or cancelled campaign?
Paused campaigns can be resumed once the cause is cleared, for example after the domain is delisted. Cancelled campaigns can't be resumed.
Does every blacklist listing pause my campaigns?
No. Only high-severity listings pause campaigns. Moderate-severity lists are typically ignored by major ESPs, so your campaigns keep running and you still get an alert.
What happens when my spam rate crosses 0.3%?
You're alerted immediately, so you can review your copy, targeting and list before it turns into a bigger problem.
