The operator's deliverability checklist

A campaign that never reaches the inbox is a campaign that never happened. Before you scale volume, walk this checklist.

Authenticate

SPF, DKIM, and DMARC should be green before the first marketing send. Maildrill surfaces domain status in Settings → Domains so the team does not guess.

Warm deliberately

Ramp volume from known-engaged contacts. Avoid blasting a cold list on day one — reputation compounds slowly and breaks quickly.

Monitor placement

Watch bounce, complaint, and open trends after every send. Campaign detail KPIs exist so you can catch drift early.

Recover fast

Suppress hard bounces, honor unsubscribes immediately, and fix content that trips spam scoring before the next batch.
