I need to add more content to a subscription preferences page; I learnt the other day it’s only possible by making changes in the email page’s code (Settings → Tools → Marketing → Email).
I introduced the changes, but now I can’t see what it’s going to look like on the page as the “Preview” shows nothing at all:
I reached out to HubSpot support and was told there’s “break” in my code, and that’s the reason for this blank view. The lady, however, couldn’t be more precise about it and just referred me to this forum.
I’m really not sure if this is the code’s fault because I realised all the other, already published, correct codes, display blank pages too after clicking “Preview.”
Is there any other way of checking what it’s going to be like on a live page than just “publishing changes”?
I’d appreciate any help and tips. Thanks in advance!
