If reputation dips, sending slows down

Bounce and complaint rates are tracked around the clock. When a score slips, sending throttles automatically while it recovers.

Blocklists and spam words

Catch problems before a prospect does

Domains are checked against the major blocklists, and every subject and body is scanned for spam triggers before it sends.

Book a demo
Is warmup really unlimited?
Yes. Warm as many mailboxes as you connect, on every plan including Starter, at no extra cost.
How long until I can send safely?
New domains typically warm over 2–3 weeks. MailOptimal ramps volume automatically and tells you when an inbox is ready.
Do you test against Gmail and Outlook?
Placement tests cover the major consumer and business providers so you know where you land before you scale.
What happens if my reputation drops?
You get an alert, sending throttles automatically, and spam correction works to recover placement.
