OrbiSearch is an email validation API that tells you whether an email address is deliverable before you send to it. It checks DNS records, MX records, and mail server responses to determine whether a mailbox actually exists — without sending a real email. Use OrbiSearch to:
  • Clean email lists before a campaign to remove invalid addresses and protect your sender reputation
  • Validate email addresses at point of entry so bad data never enters your system
  • Enrich contact data with deliverability signals, email provider, and account-type flags

Verification statuses

Every email OrbiSearch verifies returns one of four statuses: Each result also includes a substatus with the specific reason, a plain-English explanation, the detected email_provider, the mx_record for the domain, whether the domain is a catch-all (is_domain_catch_all) or sits behind a secure email gateway (is_secure_email_gateway), and boolean flags for is_disposable, is_role_account, and is_free.

Pricing

Each verification costs 0.2 credits.
