MailerCheck

MailerCheck allows verification of single email addresses, bulk list uploads, or real-time email validation via API. The email validation API verifies new addresses as collected and instantly filters out emails with typos, errors, catch-all domains and more. Detailed reports identify safe, risky, and harmful emails with 98% accuracy. Real-time verification returns status including: valid, invalid, typo, mailbox not found, mailbox full, catch-all address, unknown email, or disposable. MailerCheck accounts include 10 free credits with pricing starting at 1 cent per email. The platform improves deliverability by screening bad addresses before list addition and maintains sender reputation by avoiding high bounce rates.
