Glad to hear you like Sidebar!

And you're right, the open rate is much lower than usual (19% vs 63% for the one before). I didn't noticed it before because the daily edition containing the same referral link that I sent on the same day went through fine.

This happens from time to time and I'm not sure what I can do about it.

I honestly don't understand how Gmail's spam filter can be so "dumb" (at least from a human point of view). You'd think that if someone open, reads, and clicks emails from a particular address regularly, the filter would be smart enough to know that there's a very high probability it's not spam.

Gmail's spam filter definitely seems to be erring on the aggressive side nowadays. I honestly can't remember when any real spam last reached my inbox. On the other hand, I did find many other false positives while going through the spam folder, mainly from newsletters and social notifications I really have subscribed to.

I guess the least we can do is help Google tune their filters and periodically mark all false positives as "not spam".

Agreed.

Additionally one might go as far to suggest false positives are more problematic than the occasional spam mail.
