Why verify in Zapier

Verify every new lead or form entry the moment it appears and pass only good addresses on to your CRM or email tool.

A Mailbite API key (API access is included in every paid plan) and an automation that can send a web request with a header.

How it works with Zapier

  1. Create a Zap with your trigger, for example a new form response or a new spreadsheet row.
  2. Add the action Webhooks by Zapier, event Custom Request. Method GET, URL https://mailbite.io/api/v1/verify?email= followed by the email field from your trigger. Webhooks needs a paid Zapier plan.
  3. Under Headers add Authorization with the value Bearer YOUR_API_KEY.
  4. Add Filter by Zapier: continue only if the result field exactly matches valid.
  5. Add your next action, for example Create Contact. Use Paths if you want risky and unknown results to go to a review sheet instead.

A tip: Zapier limits how long a step can wait. If a step times out, replay it; a slow mail server is the usual cause.

What the results mean

  • Valid: The mailbox exists. Send.
  • Invalid: The address cannot receive mail. Remove it.
  • Risky: Accepts mail but cannot be confirmed, for example a catch-all domain. Send in small batches and watch bounces.
  • Unknown: The server did not answer. Retry later.

Frequently asked questions

Do I need to write code?

No. The request and the filter are fields in the Zapier editor.

What does a check cost?

One credit per verification, also when the result is unknown. A malformed address returns an error and is not charged.
