Heybounce

Heybounce is an email verification service that offers fast, accurate, and secure email verification. Its primary goal is to help companies reduce bounce rates and protect their sender reputation.

Bulk email list verification: Upload CSV/XLSX files to validate large email lists. Remove invalid and risky emails, and land in the right inboxes.

API integration: Allows real-time email verification integration to your platform. Catch invalid sign-ups when they happen, verify your lead pages, or integrate wherever emails are collected.

It checks emails for valid syntax, domain existence, SMTP connectivity, and flags risky addresses such as disposables, spam traps, catch-alls, and role-based emails. Heybounce also offers team accounts for collaboration, customizable validation filters to fine-tune which addresses should be allowed or blocked, and flexible pricing for every budget.
