Terms of Service

Last updated: 23 September 2026

By using BounceLens (the website and the Google Sheets add-on) you agree to these terms.

The service

• BounceLens checks email addresses for format, domain, mail server, typos, throwaway domains, role addresses and duplicates. It is free.
• It does not confirm that a mailbox exists. A result of "unconfirmed" means the address may still bounce.
• Results are provided "as is", without any warranty. We do not guarantee accuracy, delivery rates or availability.

Acceptable use

• Only check lists you have a lawful reason to hold, such as people who signed up or are your customers.
• Do not use BounceLens to send spam, build lists by guessing addresses, or break any law (including anti-spam and data-protection laws).
• Do not try to overload, scrape or disrupt the service.

Partners

Links to paid checkers (such as Bouncer) take you to another company's service. Their terms apply there. We may earn a commission.

Liability

To the extent the law allows, BounceLens is not liable for any loss arising from using the results, including bounced emails, blocked sending accounts or lost business.

Changes

We may change these terms or the service. The date at the top shows the latest version. Questions: [email protected].
