Hi @babyvella, 

Thanks for sharing this experience in the Community. Is there any additional information you might be able to provide regarding this link error that might help me and/or others in the Community evaluate what the issue might be? Is it a link to a facebook page, or is it an integration error? If you can provide any photos or more details on how the link is not working, that would be super helpful! 
I know you said that you sent yourself a test email, so this might not apply, but in some instances, links might not work for Previews. You can read more about that here if you are viewing in Preview. Additionally, this article will walk you through where to add and edit links for your Social Link Blocks.

Let us know if there’s any more info/examples you’d be able to share with folks in the Community.
