Reading the throughput estimate

How long a campaign will actually take to finish.

Updated Sep 10, 2026 1 min read

The Throughput estimate card on the Schedule tab turns your settings into a real forecast.

What it shows

Total leads, daily sending limit, sent today, remaining today, campaign limit, available mailbox capacity, the maximum currently achievable, sending days per week, window length, estimated emails per hour, emails per sending day and emails per week.

How to use it

Divide total leads by emails per week. If the answer is longer than you can wait, add mailboxes rather than raising the per-mailbox limit — that is the change that protects reputation.

Important notes

"Maximum currently achievable" accounts for mailbox capacity, so it can be lower than your campaign limit. That gap is the thing to fix.
