Bounce Inspector is an email verification service designed to clean your email lists and improve deliverability. It ensures your campaigns avoid invalid, inactive, or bouncing email addresses, helping you maintain a healthy sender reputation.
We use a combination of advanced algorithms, SMTP checks, and real-time validations to determine whether an email address is valid, invalid, disposable, or likely to result in a hard bounce, among other checks.
Cleaning your email list helps improve deliverability rates, reduce bounce rates, protect your sender reputation, avoid spam flags, and save money by targeting only valid leads.
Maintaining a clean and high-quality email list ensures you preserve the effectiveness of one of the most powerful marketing channels.
Bounce Inspector can identify non-existing emails, deleted emails, malformed emails, and disposable emails.
Based on this identification and additional checks, we provide a simple classification of emails into three categories: whitelisted, blacklisted, and greylisted.

A valid email address can bounce for several reasons unrelated to its validity. Common causes include:
  • The recipient's mail server might be down or unreachable (Temporary server issues)
  • The recipient's mailbox is full and cannot accept new messages
  • The message might exceed size limits set by the recipient's mail server
  • The message might be flagged as spam or rejected by the recipient's server due to various factors, such as a blacklisted IP address, spam-triggering keywords in your email content, or sending a high volume of emails in a short period without proper warm-up, SPF/DMARK/DKIM DNS configurations...etc.
  • Incorrect configuration
If the email is truly valid, the bounce is typically a soft bounce, and the issue may resolve over time.
