NeverBounce Bulk Email Verification Service Review

Over 130,000 users use NeverBounce for their real-time email verification and list cleaning services. NeverBounce guarantees companies reach their customers by dramatically increasing the delivery of their emails to the inbox. By checking email validity against a database of 6 Billion emails and excluding outdated email addresses, NeverBounce increases deliverability and helps businesses adhere to strict email provider guidelines.

NeverBounce will clean your email list, so you never have to face any bounced emails. Just upload your list, or connect to 85 integrations. Download your clean list, and enjoy a 99.9% email delivery rate (guaranteed).

NeverBounce uses a 20+ step cleaning process and checks each email 75 times from around the world.


Here’s a peek at the process:

  • Real-time verification combined with accept-all detection.
  • Advanced verification of mail services to verify user identification using SMTP and other proprietary methods.
  • Automatic elimination of duplicate emails and bad syntax.
  • Domain check to view the current status.
  • Removal of possibly malicious emails.
  • Validation of all email types and from all major providers.


All results are cut down into categories:

  • Valid: A tested real address
  • Invalid: An invalid address
  • Accept all: Unverifiable
  • Disposable: Temporary address that’s unsuitable for sending
  • Unknown: Server cannot be reached, so emails are unsuitable


Results are also segmented for download, so you don’t have to do any extra work in Excel or other software.

NeverBounce will even recommend emails you should send. Once an email address has been classified, it will be labeled as “send” or “do not send,” so you don’t send emails to addresses that are invalid or cannot be verified.

The Clean function helps you maintain a list of valid email addresses.
