Customers have emailed us to say the links in one of our campaign emails are broken.
Here’s an example: HTTP 404 - Wikipedia
It should go to our Saboteur Assessment results, but instead goes to Wikipedia’s page on 404 errors.
For each contact, the custom field value is correctly populated with a working link.
Infusionsoft chat has not been able to identify the problem. There is no similar issue in Known Issues.
Has anyone encountered this issue?
Looks like it’s a recurrence of this issue:
### Links with URL’s containing merge fields are resulting in a HTTP 404 Wikipedia page when clicked.

There are a number of reports of this issue returning (they currently show it as resolved). So anyone experiencing this submit a ticket and reference the issue number 1586140 so they can open up investigating it again.
It is 9 Aug 2021 and I am now getting this same issue. The link is correct in my Campaign but when the email is sent and clicked on by end user it goes to Wikipedia 404 Error.
Is this a common issue for others, or just me? Is there a fix I need to do at my end, or is it a global error that needs to be fixed?
Possible work around that worked for us:
We changed the link to a vanity link that redirects to the one with all the params and it worked
