Stop losing new signups to mistyped addresses and protect your sender reputation from hard bounces. Check whether a domain accepts mail, suggest inline fixes like gmail.com for gmial.com while the customer is still on the form, and filter out throwaway or dead mailboxes before you send.

Check an address while the customer is still with you. Turn the answer into a useful next step.
Check a single address during signup and checkout, or validate up to 1,000 addresses per 128 KiB batch request before launching a campaign through Bird’s API, SDKs, CLI, or hosted MCP.
When a customer types aisha@gmial.com at checkout, Bird flags the likely misspelling and returns aisha@gmail.com as a suggestion without overwriting their original input. Prompt the customer to confirm the fix on the form so order confirmations and welcome emails reach the right inbox.
Combine the deliverability verdict and 0 to 100 confidence score with address flags that identify burner providers, shared role inboxes like support@ or info@, and free consumer domains. Reject dead domains and non-existent mailboxes outright, or apply custom rules to catch-all domains and B2B signup forms.
Email validation checks whether an address is real, deliverable, and safe to mail before you send anything. Email verification with a one-time passcode proves that the person signing up can access that inbox. Run validation first to catch typos and burner domains before paying to send a verification email.
Pair email validation with phone number checks to screen contact details at signup. See email validation pricing for per-lookup rates as your volume grows.
Confirm a phone number is valid and check its country, serving carrier, and line type in one call.
→Use a 0 to 100 risk score to flag suspicious or low-trust phone numbers during signup and checkout.
→Distinguish mobile numbers from landlines, VoIP, and toll-free lines before paying to send an SMS.
→Organize teams in workspaces, control API access, and trace changes through audit logs.
