Validation that doesn't put your reputation at risk.
Older tools verify an address by pinging the recipient's mail server. Mailbox providers now treat that like a spammer probing for valid addresses, so it gets you rate-limited or blocklisted, and the answers are unreliable anyway. Bird checks each address against real delivery and engagement history instead, so you learn whether an address actually receives mail without ever touching the provider or risking your reputation.
What your validation results tell you.
Every address comes back in one of five buckets, so you know exactly what to do with it.
- 01
Valid.
Seen accepting mail or engaging in our data. Safe to send.
- 02
Invalid.
A confirmed hard bounce. Don't send: it will bounce and drag down your sender score.
- 03
Risky.
Low-quality addresses: disposable inboxes, masked addresses, or role accounts like info@company.com. They may bounce or complain, so most senders exclude them.
- 04
Typo.
Valid syntax, but the domain looks misspelled, like john@gmsil.com. We suggest the likely fix so you can correct it at signup or drop it from a list.
- 05
Neutral.
Passes every check and has never hard-bounced, but we have no delivery history for it yet. Low risk: send to it, or wait for engagement proof first.
Where validation fits in your workflow.
Validate in real time on a signup form to catch typos and block disposable addresses before they reach your database. Validate a whole list before a campaign to strip invalid and risky addresses and keep your bounce rate down. And re-check older lists now and then, since addresses that were fine at signup go stale as mailboxes close.
