Check that addresses are valid before you send.

About this page
Email verification checks that an address is likely to receive mail before you send to it. Removing invalid addresses lowers bounce rates, which protects your sender reputation.
Verification gives a probability, not a guarantee. Some addresses cannot be confirmed either way, so tools report them as unknown or risky.
What to check before choosing
- Whether it offers bulk list cleaning, real-time API checks, or both.
- How it labels uncertain results, such as catch-all domains.
- Whether credits expire.
- Whether it connects directly to your email platform.
