I'm so frustrated! My most recent event promotion email in Backstage has been a total disaster! 670 recipients with 4 links taking them to a UTM tracking code error, not the website! 

My Zoho Backstage website is https://events.happyhour.group, which is great and works really well but for some reason when linked from Campaigns, the tracking code resulted in an error! Could it be that the platform doesn't recognise .group as a valid TLD?

Can anyone see why this might have been?
