Hello @Office_Brands ,
Are you wanting whatever was linked broken? Or are you simply not wanting your contacts to access that particular link for that particular email?
Our higher level technical team can break links that are hosted in our system (documents, landing pages, etc.), if you call in and confirm security permissions along with your request. However, please keep in mind that this will absolutely break the link for everywhere it was posted - including previous emails, website hyperlinks, and social posts. If you still want the document, landing page, or whatever active and available, then this will not be a viable option for you.
If you do still want the documents, LPs, etc. linked that you sent out, then it's strongly suggested you send out a copy of the email with fixed links and a subject line noting the correction/update.
