Email verification
Email verification for B2B sales outreach
Protect your sending domain before the first cold email.
What usually goes wrong
Guessed addresses ([email protected]) that look right but do not exist.
Catch-all company domains that accept everything, so a bounce never tells you the address was wrong.
People who left the company since the list was built.
An example
A rep verifies a prospect list before loading it into the sequencing tool. Invalid addresses are dropped, risky ones go into a slower sequence, and the first send is small enough to read the bounce rate before scaling up.
How to do it with Mailcut
- Export the prospect list from your lead database as a CSV.
- Verify it and download the three result files.
- Load only valid addresses into the sequence at full speed; put risky addresses into a small, slow batch.
- Watch the bounce rate on the first send and stop if it is high instead of continuing.
Frequently asked questions
What does risky mean for a company address?
Usually that the domain accepts every address (catch-all), so the mailbox cannot be confirmed. Send to those in small batches and watch the bounces.
Does verification make cold email safe?
No. It removes dead addresses, which protects your reputation. Relevance, volume and your sender setup still decide whether mail reaches the inbox.
Should I verify again before every campaign?
Yes for lists more than a few weeks old. People change jobs and mailboxes close.
