Early access: send from your own mailbox today. What works

Inboxed + MillionVerifier

Optional: send only the addresses Inboxed can’t confirm to your MillionVerifier account, one credit each.

MillionVerifier is a low-cost second check for the addresses Inboxed’s free verification can’t settle. Everything else stays with Inboxed’s own result.

What you can do

  • Confirm uncertain addresses with MillionVerifier
  • Mark rejected addresses invalid so they’re never sent or charged
  • Fall back to Inboxed’s result if it can’t answer

Set it up in 3 steps

  1. In MillionVerifier, open API in the left menu.
  2. Copy your API key.
  3. In Inboxed → Integrations → MillionVerifier, paste it.
