What usually goes wrong

Typos in the registration form, so the joining link never arrives.
Free-event sign-ups with throwaway addresses that inflate the registration count.
Post-event follow-up sent to a list that was never checked, right after your best chance to be remembered.
An example

The organizer verifies the registration list the day before the webinar, mails the corrected and valid addresses their reminder, and uses the invalid list to contact the few people who can still be reached another way.

How to do it with Mailbite

  1. Export the registration list as a CSV from your event or webinar tool.
  2. Verify it and download the result files.
  3. Send reminders to the valid file; follow up with the invalid ones by another channel if you have a phone number or a form reply.
  4. Verify the attendee list again before the post-event follow-up.

Frequently asked questions

Can I check addresses while people register?

Yes, through the API, one address per request. Show an error when the result is invalid so the person can fix the typo.

Should I refuse risky addresses?

No. Accept them; the result only means the mailbox could not be confirmed.

Is there a limit on list size?

The free plan covers 100 verifications a month. Paid plans are listed on the pricing page.
