How long does the URL for a campaign stay live?

Hi @LauraPatterson , 

Great question! There is no reason that the URL should not stay live after you send the campaign. It is considered permanent, so you do not need to worry about it being deleted.

If for any reason you do need the campaign URL broken at some point, our higher level technical team can attempt to break the link if requested. To submit this request, please call our general support so they can confirm security permissions live with you, and submit the request the Tier 2 team.
