ZeroBounce vs. validTo

What is ZeroBounce?

ZeroBounce is an email validation and deliverability platform that reduces bounces and helps in placing emails in the inbox. The software was developed to make email communication safer, more reliable, and more efficient. Features include an email validator to reduce and eliminate invalid, abusive, inactive, "catch-all", temporary, and spam trap email addresses, as well as an email server tester and an inbox placement tester. The latter shows where emails end up with popular providers. Up to 100 emails can be validated for free. Afterwards, the tool can be purchased starting at $16, depending on the number of emails.
