For comparison I have two REALLY well-trafficed admin email addresses - one a gmail account and one an Outlook 2016-managed POP3 of a unique domain.
Now, the Gmail account inbox is, for all intents and purposes, completely spam-free. Zip. Zero! Nothing. Nada. Love it!
The POP3 on its own domain is a godzilla of waste and destruction. Used to be god old SpamFighter was MORE than enough - a TITAN of power. https://www.spamfighter.com/
where NOTHING spam-ish got through.
Sadly, now, it seems to me SpamFighter has lost whatever ability it had to handle even emails I get with titles like: NUEVA PLATAFORMA DE ARQUITECTURA & MARKETING DIGITAL. Over 10 of them staring me in the face right now.
Nor ones with such subtleties as: Business funding services for your company?
Right there in the subject line.
And! For the 10+ mentioned above - two arrived only minutes apart on the same day.
Also! I've got the app at the strictest settings.
So - what is it that Experts rely on? Is SpamFighter the best? Or...is there something else that can do the job better?
PS - SpamFighter is US$30 a year! So it's sort of an exquisite let down to be paying for it and wading through so much spam.
