On the face of it looks good no ? A simple Apple mail extension provided from Hubspot - that allows you to just check 'track mail' - just before you send, so that you know when someone opens your email. I used it selectively when I was trying to ensure that important things were being seen.

And then Today

Suddenly – none of my email was getting through to my recipients. I escalated to my ISP – Siteground – who really are VERY good BTW – who came back to me in three minutes to highlight that

The reason why the e-mails were bounced back is because they contain an URL which is blocked in the SPAM list https://spamrl.com/.

But – I wasn’t using Sidekick. So, I disabled it – and lo – mail goes through no problem. Needless to say – uninstalled completely.

Which brings me to the second #FAIL

To uninstall I had to use Chrome to go get an uninstall script. Easy enough to find – except when you run it – Apple security won’t let you open it because the script is from an unidentified developer.

So – across to ‘system preferences’ – and accept that running


is ok by me.

All now back to normal. MANY THANKS – again – to Siteground for such rapid response.

And SHAME on Hubspot for allowing their clever little side project to be added to a spam list – but even more – why not just identify yourselves for the uninstall.
