How to Block Specific Emails or Domains from Registering to Your Events

To protect your event from spammers and unwelcome guests, you can block specific email addresses and email domains from registering by using our Registration Block List.

For any given webinar or event, you may not want everyone to be able to register. Whether you want to block specific email addresses of known spammers or otherwise unwanted users, or if you just want to allow email addresses from your internal organization to have access, you can accomplish this and more with Block and Allow lists.

If anyone on the Block List or not included in the Allow List attempts to join your event, their registration will not be completed and they will receive a message notifying them that they will not be able to register for your event. You can also add these custom email addresses/domains to your channel's settings so they carry over from event to event.

How to use the Registration Block List

Note: You can only block or allow emails at one time, you cannot block AND allow emails. Additionally, you can only use one list at a time. You will get a notification to enable on the Block List or Allow List

Visit your webinar dashboard for session or event you want to manage, then click on Allow & Block Lists from the left-hand navigation. You'll need to select whether this content will be using a block list or an allow list.

After choosing an option you'll get a prompt to confirm. It's important to remember that if you use the allow list, only the email addresses that are included in the allow list will be able to register,

For either list you can add individual emails or upload a single column CSV file with the list of email address to add to the list. Once added to the list, you can search for and delete any email address.

You can also use these settings to block or allow entire email domains. To do this, you will add asterisks as wild cards to the email address you add to this list. For example, if you want to block anyone from using a Gmail email address from registering, you would add this to the block list:

*@gmail.com

You can also use asterisks to block or allow multiple different domains that might use different extensions. For example, you may want to block Yahoo email addresses, but you want to ensure that you block all the different versions of the domain for the various countries, like yahoo.fr or yahoo.de.

Use the following format to block a domain with differing extensions:

*@yahoo.*

Within each list is an Exception List, where you can make exceptions to domains that you would like to block. For example, if you are blocking any email addresses with a @gmail.com domain, you can enter in an exception for a “janedoe@gmail.com” to be blocked or allowed. You can enter in individual email addresses or upload a CVS file.

You can also block or allow email addresses channel wide in the channel settings. Go to your channel’s Settings page and scroll down until you see the Block List tab in the left hand navigation menu.

Here, you can expect the same functionality as the Block List found on the Manage Webinar dashboard. You can upload CSV files or individual email addresses/domain types here as well. These lists will be applied channel wide in addition to any newly created webinars. If they do not appear immediately, you may need to refresh the page to view.

It’s important to note that email addresses or CSV files added into the webinars will not be added into the Channel Block List. Only the email addresses added into the channel’s Block List will be added to the webinar’s block list and will show under a separate channel block list section.
