You could create a filter, if you can find a search that will hit only the emails you want, and have all matching messages deleted? Or at least "never send to spam" but instead moved to a special folder if you want to review them too.
I thought that maybe some characters that never show up in your language like ф peraps? But apparently Gmail doesn't search like that, here's a good overview from another answer:
The Gmail search functionality works based on what I would describe as tokens. A token is any sequence of alphanumeric characters separated by a space or by other non-alphanumeric characters such as underscore, full stop (period), "@", dash, etc.. So in [email protected] there are 4 tokens: "peter", "ford23", "example" and "com".
Wildcards within tokens do not work.
So Gmail only searches by words or parts of emails. Even the .
in the examples below may be unnecessary (from:.ru
may be the same as from:ru
)
Or something like from:.ru
should match all messages whose from address contains .ru (I tested from:(.com)
that matches anything.com addresses, while from:(.co)
matches emails containing .co like @yahoo.co.uk
.
There may be a combination of "tokens"/words in the from:
, subject:
,body:
that might match enough messages...
There used to be a good language search, but apparently it doesn't work anymore. This guy said that Gmail could search emails by language using lang:[code]
, like lang:ru
for Russian. More language codes should be here. I don't think I have any emails like that so couldn't test, but trying lang:en
didn't show any hits, so it looks like it's no longer available.
Or, you could try a filter for the "false positive" spam you frequently see and keep those out of the spam folder, maybe search for your name or something unique? That would probably result in a lot of spam not in the spam folder though.
false positive
term? I don't know how many e-mails incorrectly marked as spam I have "ressurrected" from that folder for past five years of using Gmail. Having this folder flooded with Russian junk makes such browsing much harder. It is quite difference, if you have 10 spams per day versus if you have 15 spams per hour, right?
