Question 1

How does email validation improve deliverability?

Accepted Answer

Email validation identifies and removes invalid email addresses from your lists, preventing bounces that can harm your sender reputation and reducing the risk of being flagged as spam.

Question 2

What types of validation does BounceBuster perform?

Accepted Answer

BounceBuster performs email format validation (RFC syntax checking), DNS domain verification (confirming the domain exists), and MX record checking (verifying the domain can receive email). All validation runs locally on your computer -- no data is sent to any server.

Question 3

Does BounceBuster upload my email lists to any server?

Accepted Answer

No. BounceBuster runs 100% on your computer. Your email lists are never uploaded, transmitted, or shared with any server. The only network activity is standard DNS lookups to verify email domains, which do not reveal the email addresses being validated.

Question 4

Is there per-email pricing or a monthly subscription?

Accepted Answer

No. BounceBuster offers a one-time purchase of $19 for unlimited email validation. There are no per-email fees, no monthly subscriptions, and no usage caps. You can validate as many emails as you want, forever.

Question 5

Can BounceBuster process CSV email lists?

Accepted Answer

Yes, BounceBuster supports CSV and Excel file formats, making it easy to validate email lists from various sources with bulk processing capabilities.

Question 6

How can I reduce email bounce rates?

Accepted Answer

Regular email list cleaning with BounceBuster helps reduce bounce rates by identifying and removing invalid addresses before sending campaigns, resulting in improved deliverability and sender reputation.
