Sending limits that protect your domains

Preflight checks, per mailbox daily caps, an automatic complaint pause and a do-not-contact list run before and during every campaign, so one bad send does not cost you a domain.

Sample data. A launch preflight checklist with one blocker, a complaint watch for a running campaign, daily caps by mailbox age and the do-not-contact list.

What you get with safe sending

These run on every campaign without any setup, and they keep your sending domains healthy.

Sample preflight
The plan allows managed campaigns
Every variant has the required placeholders
The campaign has no prospects. Import some first.
No mailbox sits on a domain with verified SPF, DKIM and DMARC.
Not ready: 2 blockers

Preflight lists every blocker

Before a campaign launches, preflight checks the plan, the free campaign slots, the sequence, the prospects and the mailboxes. A campaign launches only when the list of blockers is empty, and each blocker is written out so you know what to fix.

Complaint rate against the pause line
This campaign0.08%
Pause line0.30%
The pause line applies from 100 sends. Three complaints always pause.

Complaints pause a campaign

Three spam complaints pause a campaign at any volume. So does a complaint rate above 0.3 percent once it has made 100 sends, the line large mailbox providers ask senders to stay under. The pause is recorded even when the sending engine cannot be reached.

A do-not-contact list that fills itself

Spam complaints and hard bounces add the address to the do-not-contact list automatically, and you can add addresses yourself. Listed addresses are skipped at import and can never be booked for a meeting.

Frequently asked questions

What pauses a campaign?
Three spam complaints pause it at any volume, and so does a complaint rate above 0.3 percent once it has made 100 sends. The pause is recorded even if the sending engine cannot be reached.
Can a campaign launch with a problem?
No. Preflight lists every blocker, from a missing prospect list to a domain whose records are not published yet, and the campaign launches only when the list is empty.
Can I add people to the do-not-contact list myself?
Yes. Add addresses through the API at any time. Listed addresses are skipped at import and are never booked for a meeting.
