Why you should do regular email list cleaning
Cleaning your subscriber lists on a regular basis with an email verifier tool like MailerCheck is a top priority. Here’s why!
Prevents emails going to spam
Your list makes spam filters happy with emails that go to the inbox.

Your bounce rates will improve when emails only go to valid addresses.

Your emails perform better when they go to people who actively engage.

Using MailerCheck in your workflow
MailerCheck’s email address verification, analysis and list cleaning tools can be used anywhere that you collect email addresses.
Use our real-time API to verify new email addresses as you collect them and instantly filter out emails with typos, errors, catch-all domains and more!
Here’s how our email validator works:
As emails are entered into a registration form, MailerCheck verifies the quality of the email address in real-time.
It immediately returns one of the following statuses: valid, invalid, typo, mailbox not found, mailbox full, catch-all address, unknown email, or disposable email address.
Your registration page will then take further steps, for example, by asking users to re-enter their email address if it has a typo.
You can rest assured that you’re only collecting clean emails.
Enjoy our real-time email verification service by connecting your web apps using Zapier, or by making calls to our email verification API from within your apps.
