Sendgrid email verification with BillionVerify
SendGrid (Twilio SendGrid) is a developer-first email platform for transactional and marketing email at scale. Adding BillionVerify in front of SendGrid ensures every recipient is verified before send, so bounces never threaten the shared sending reputation your delivery depends on.
Why verify before the send
On SendGrid, a bad batch can suppress future delivery and hurt your sender score across all of your mail. Verifying with BillionVerify before the SendGrid send removes invalid, disposable, role, and catch-all addresses, keeping bounce rates low and throughput high.

Validate API-driven signups
Call BillionVerify at signup before storing the address and sending the SendGrid welcome email, blocking junk accounts at the edge.
FAQ
Why verify before sending with SendGrid?
SendGrid reputation is shared across your sending; one dirty batch can defer or block future mail. Verifying first keeps bounce rates low and delivery fast.
Can I verify in real time per message?
Yes. Verify each recipient inline before the SendGrid call, or pre-verify a whole list in bulk for large campaigns.
What does a verification result include?
Status (valid, invalid, risky, catch-all, role, disposable), a deliverability flag, a confidence score, MX data, and the reason — everything you need to decide whether to send.
