Webinar Registrants With Fake Emails: Why They Happen and How to Spot Them

··2 min read

Registrants with fake emails are usually throwaway addresses used to get the replay, or typos from mobile entry; verify the export and the reasons Disposable address, Mailbox not found, No mail server and Typo domain pick them out. The bulk disposable email checker finds the first group, and the email verification for webinars and events page covers the whole list.

Why registrations go bad

Free gated pages invite throwaways. Anyone who wants a replay link without a follow-up uses a temporary mailbox. After an ad push, the share of such sign-ups can climb.

Mobile entry adds typos. A missing letter in gmail.com means the joining link never arrives, and that registrant blames you.

Step 1: export the registrants

Pull the CSV from your webinar tool. Our export guide for webinar registrants shows the steps for common platforms.

Step 2: verify

Upload it on the verify page. Look at the reasons:

  • Disposable address: not a reachable contact after the event.
  • Mailbox not found, No mail server: the link cannot arrive.
  • Typo domain: fix it with the typo corrector and send the link.
  • Accepts all addresses: send, but you cannot confirm delivery.

Step 3: reach fixable cases another way

If you collected a phone number or the registrant used a work domain, contact them directly. For checking numbers as well, see verifying registrants before reminders.

Step 4: show the joining link on the thank-you page

Put the link on the confirmation page as well as in the email. That way a bad address does not mean a lost attendee, and it is a fix that costs nothing.

Step 5: judge the campaign on real registrants

Report registrations with and without invalid rows. If one traffic source brought most of the fakes, you have learned something about that source. The bounce rate by source tool helps compare.

What this cannot do

  • It cannot tell a real person using a throwaway from a bot.
  • A valid result means the mailbox exists, not that the person will attend.
  • Yahoo, AOL and Microsoft consumer rows come back risky.

Check your registrants

Upload them on the verify page: the first 100 checks are free with a Google sign-in, no card. See pricing for larger events.

Common questions

Why do webinars get fake email registrations?

People want the gated replay or slides without joining a list, so they use a throwaway address. Others mistype on mobile and never notice.

How do I spot fake emails in a registrant list?

Verify the list. Rows marked Disposable address, Mailbox not found, No mail server or Typo domain are the fake or mistyped ones.

Do all of them need to be removed?

Those four reasons are invalid, so they cannot get the joining link by email. Keep them in the attendee count but not in the follow-up list.

When should I check?

The day before the reminder, so you have time to contact fixable cases another way.

Is it free?

The first 100 checks are free with a Google sign-in, no card.

Check your list before you send

Real mailbox checks over SMTP, and nothing is sent to the address. Sign in with Google and your first 100 email checks are free, no card. Plans for bigger lists are on the pricing page.
