Emails end up in Gmail spam, what could be wrong?

Question

gmail

I have an Smtp server, everything is absolutely set up, also my server's ip is not in the black list of spam addresses anywhere and. etc. My letters pass all the checks, but still end up in spam on gmail. How can this issue be resolved. Those. hosting support can’t even do anything, advises contacting those. google support, but there they are unlikely to ever answer.

Answer 1

try to look at the reputation of your IP address on the sites https://www.senderscore.org/ and https://www.senderbase.org/ - maybe some other letters are coming from your IP address, but you don’t know about it I know.
And you can also gradually change everything in turn and try to find what is the reason:
- replace the content with the word "hello" to exclude the influence of the content
- replace from-email
- replace from-name
- replace from-domain
and so on. Using the scientific poke method, we get an element that affects deliverability. And yet - it's better to test on a zero gmail box without a history of interaction with letters, maybe it's some kind of your personal filter that sends letters to spam.

Answer 2

At one time there was an article on Habré impregnable mail server
. I used it as a checklist (so as not to forget anything) for setting up mail. Perhaps it will lead you to some idea, what else can be adjusted to appear white and fluffy in the eyes of the google mail anti-spam

Answer 3

Before complaining about how bad Google is, you would show an example of a letter.
I once suffered for 4 days with the mailer (also for free, sic), it turned out that people send letters like "go to the page and earn a million bucks."

Answer 4

Reverse DNS zone for the mailer + SPF + DKIM + DMARC + "Precedence: bulk" header if it is a mailing list + the content of the emails must not look like spam. Plus, the percentage of reading should be high if this is a newsletter. Then it should be easier.

Answer 5

A lot of things have been rightly written above.
Including that it would be cool to see the letter.
What else can you see:
Do you use a tracking pixel?
Additionally, check for site IP blacklists (not just the mail server).
