Hi guys,
I was talking with a buyer of postal history via email.
He request to pay with paypal and I have refused, sending the following short message:
*(translated) I don't have Paypal. I accept payment with crypto (bitcoin / ethereum / litecoin etc).

Guess What? The email has been rejected by GMAIL!
"Message blocked because it contains content identified as spam."

have you ever seen something like this?

Personally I have never faced the problem of such kind. Regularly use Gmail, and lots of my friends who are ingaged in crypto, use it, and everything is going on without any questions like that. May be there was some other reason that you did not notice. Very often really valuable mails get into the spam box and even when such words like bitcoin or crypto were not mentioned. Sometimes their inner policy is hard to understand and explain.

I personally have never felt like you have experienced, a lot of my Gmail received news about crypto between deposits, withdrawals, news but it didn't enter spam bro. Usually my gmail spam is just a scammer who sends me an email

This has not personally happen to me, although some crypto related messages had been spam in the past, but still got my bitcoin mentioned messages on my inbox. Telegram works well though for bitcoin related discussion if gmail ever filtered it again.

Gmail uses AI to detect and block out spam. AI may use a wide range of subjacent algorithms, taking into account bags of variables, amongst which, besides the information on the email itself, it may include prior posts and additional data related to you.

Your case is a false positive, and it’s very possible that, the exact same message sent from another person goes through without any hassle. You can probably throw the algorithm off-track by changing bitcoin for something else, or adding additional text to the message itself. The spam AI may not necessarily be targeting the crypto words per se, but in a given context derived from the message’s content/context and profiling it performs.

Fortunately, these false positives do not seem to be cropping-up at a meaningful rate (I have seen just a few similar cases to yours, reported for example by a user using Hotmail, but it’s not a heavily reported issue). It’s a bummer though when it occurs.

Seen it all the time, but it's not just bitcoin to be fair I have to say!

I get even bank payment apps messages rejected automatically. Easy fix is just to whitelist certain domains or addresses and you get all the require emails in your inboxes.

Knowing how many people can get tricked, I'm not surprised at all these measures have to happen.

I haven't encountered this problem, but does Google really hate crypto that much?

I don't think that it is crypto but I haven't seen this problem, OP would probably do good if he/she were to look for the answer to the problem, I don't think that it is a crypto related problem but who knows.

The google robot might identify the words receiving payments with bitcoin / ethereum / litecoin etc as keywords to watch out for as SPAM, because nowadays many spammers create fake emails to trick people by sending their crypto. Google doesn't hate crypto but it is just security being increased to tackle a growing number of spammers.

Although I have not encountered such instance with my Gmail messaging, I think it is more like this one than other probable reasons. I think the message was too short, a one-liner, and contains such keywords or key phrases such as I accept payment, payment, crypto, Bitcoin, etc. The Gmail bot might have been triggered with them. I guess if this message is to be rephrased into long formal sentences with a heading and all, this might not be rejected at all.

I don't understand what you were trying to sell, so be honest, but it's sad that the message was outright rejected by gmail I've just tried sending a message from my gmail address to another gmail address of my friend, mentioning Bitcoin as payment, and the message was delivered successfully. Then I did the same by sending a message to another address of this friend, but we didn't communicate through this address before, and the message was also delivered without issues...
However, I did receive some messages like "please send me 0.1 BTC to unlock 1 BTC" and they went straight to spam. I think that in your case, it was just a mistake the system made.

I remember that google and youtube restricted and banned word bitcoin before so maybe it's something connected with that but I am not sure.
Google can obviously read and inspect all your emails so I would suggest using some alternative email providers that respect your privacy like Protonmail (has integrated OpenPGP encryption), Tutanota and Criptext, or think about encrypting your emails so that nobody can read their content and mark them as spam.

I'm not surprised, any mail now translates most emails into spam, whether it was really spam or not, so I always check the "Spam" folder, I don't see anything wrong with this, clean this folder and you will be happy)

Others seem to have overlooked it, but it might very well be your email address that is the problem. Are you sending gmail to gmail? Or are you trying to send from somewhere like mail.ru to gmail.com? If it is a gmail to gmail email, then that is especially odd and you might have some sort of black mark against your account. If you are sending outside of gmail into a gmail account then they will be a lot more sensitive and are likely to flag your email based on a range of criteria - subject, sender domain, body, signature, attachments or included images. If the external domain you are using is owned by you personally it will likely need to build up a history and have the proper spam protection in place.

I'm also inclined to think that this is the reason why the message was marked as spam. Some domains might be incorrectly marked as spam even though the email itself is legitimate as long as it comes from an outside domain. I've had this issue a few times, forwarding game-related details from my temp emails to my personal ones. It just marks it as spam even though there isn't anything wrong on the email nor are there any attachments on it, just plain old text and that's it.

I haven't encountered such problems in recent times. Rather I get regular emails from various crypto exchanges in my gmail address which usually contains the name of crypto quite certainly. These emails are getting delivered to the "promotions" section of my gmail account. Nothing gets blocked for sure because didn't see a drastic reduction of such emails.

That's something new! I am not sure if Google is doing this due to some country specific legislation.

Crypto Swap Exchange

Weird, I have several GMail accounts and frequently use them to buy / sell / trade things with crypto with no issues.

It might be something else in your message is causing an issue.

With that being said, do you know if the sending server has DKIM, SPF and DMARC?
Short version: DKIM is a digital signature in the header of the email so that the receiving sever knows it's legitimate. SPF is information in DNS that says mail from this domain should be coming from these IP addresses and DMARC tells the receiving mail server what to do if an incoming message fails either DKIM or SPF.
The above is very simplified, but I have seen GMail more and more tag legitimate messages when the above are not correctly setup.

I personally have never had such an experience, but I think there are several reasons why you got such a message. I think maybe your recipient has flagged messages that contain some keywords (bitcoin, crypto, etc.) as spam - or perhaps a more likely possibility is if you use Outlook as your client for which there are many examples of blocking emails showing that particular warning.

I also found another possible cause of the problem, so try to see if any of this information helps.

Some servers will reject messages as spam when the message has a signature.
If you have configured eM Client with signatures, try disabling them and see what happens.
