I like that Hubspot has an error in workflow notification, but some of the errors are more noise than helpful. If I have to clear an error everytime someone unsubscribes, I’ll spend a good part of my time clearing errors. I don’t really consider those errors.
What I consider an error is a broken link (perhaps the web page has been archived), an unpublished email, an unsubscribe rate or bounce rate that’s not healthy (rather than individual unsubs), or a trigger that’s no longer firing based on an event or property.
Thanks.
