What does email list cleaning remove?

Four checks run on every address. Each one protects your deliverability in a different way.

Detect

Invalid addresses

Removes hard bounces, closed inboxes and fake domains before you hit send.

Remove

Spam traps

Identifies catch-all servers and honeypots that can get you blocklisted by inbox providers.

Fix

Syntax and typos

Recognises and corrects common syntax mistakes, so real customers are not lost to a typo.

Speed

Fast processing

Cleaning begins immediately and typically finishes within 24 hours.

Understanding your results

What do the risk scores mean?

Every contact gets a score from 1 to 10 in your downloadable CSV report.

1–5High riskConsidered risky. Marked inactive, so they are not emailed.
6–10Safe to sendNo threats detected. Stays subscribed.
How often

When should you clean your list?

There is no single schedule. These are the moments when cleaning pays off most.

After importing a list

Old or bought-in lists carry the most invalid addresses and traps. Clean before the first send.

Before a big send

A launch or sale goes to your whole list. Make sure every address is real first.

When bounces rise

A climb in bounces is the sign your list has aged. Clean it before inbox providers notice.

Before warming a domain

Start a new domain with a clean list so AI Traffic Control ramps on good signals.
