Issue with email links sent through Single Send API


We are sending transactional emails through the Single Send API. When some recipients click on a link in the email they get the following error:

{"status":"error","message":"Cannotredirect to blankurl.","correlationId":"0a08d80b-039c-48db-b994-b594c5e16f80","requestId":"4d5f0266-64e0-42ac-9809-0eb8cf933e3e"}

What would cause this error? All of our email links have valid URLs. Maybe there’s something wrong with how HubSpot wraps the links?


Hi @jwolinsky

Can you send me a link to the email that you saw this with, and the contact that had the issue? Do you happen to have a specific example link from a customer that this happened with?
