Gmail Email landing in Spam Folder

[webmastermario]

Hello,

also i have a problem that all emails sending to gmail will land in spam. I have a fresh IP and all correctly setup with rDNS etc. But still gmail is marking it as spam. What else can i do to correct this?

Thanks

Start by sending a test email to https://www.mail-tester.com/ and check your spam score

Also be sure you have set up spf, dkim and dmarc

[webmastermario]

this is it.

[sinnbeck]

Did you set up all 3? Spf, dkim and dmarc

[webmastermario]

yes

[sinnbeck]

Can you post the mail header?

Hi,
I'm also experiencing the same problem, I get 10/10 from https://www.mail-tester.com/ but otherwise all gmail emails go to spam, has anyone solved the problem by any chance?

I await confidently

Thanks for your help

[Pacerino]

SPF, DMARC, DKIM correctly setup?
Register yourself at https://postmaster.google.com/ and take a look into your reputation from google.
How about your IP? Fresh one? Shared? Warmed Up correctly?
Whats your sending behavior? How many Mails are you sending?

Maybe you could post some headers from a spammed mails.

[pdifeo]

I think becouse the message is with a blank body content. Try writing something in the body of message.

[Danilo8024]

Hi, thanks everyone for the replies.
PSF, DMARC and DKIM are configured correctly, I registered on Google Postmaster but even validating the domain it doesn't show me any data. The IP is a new address, not shared, not present in the blacklists scanned by mxtools.

I attach a header to today's latest email (where the body content is present) where everything seems ok.

Thank you very much for helping

[Danilo8024]

Thank you for your answer,
I don't use IPv6, I checked the reputation of both the IP I use for the SMTP service on https://www.talosintelligence.com/ and it is neutral (therefore not good but not terrible), which is different for the domain (which is just registered) and it turns out that it has no reputation, maybe this is the problem, I don't think so about the text, I always create text that can look like a real email.

If the problem is the domino I think there is very little I can do, but the strange thing is that when I put my header on https://mxtoolbox.com/EmailHeaders.aspx it tells me that the dkim signature is invalid

I ran out of corners where hitting my head made my office become a sphere 😶‍🌫️

[Danilo8024]

Update, also according to Google via the site https://toolbox.googleapps.com/apps/messageheader/analyzeheader they are all ok but the emails always arrive as spam, mystery....

[Danilo8024]

Last update, this is also ok now it would seem that it interprets uppercase and lowercase differently on the TXT record but even if this works well the emails continue to go to spam.

[Goodzco]

Any news about your issue @Danilo8024 ?

[n1em1nen]

I have same problem. Wondering how to disable sending via ipv6 but no one seems to know. Based on the Gmail headers @Danilo8024 is sending with ipv6 as well and Gmail tends to put ipv6 mails into spam folder. On postfix it was easy, just do inet_protocols = ipv4 but no anything like that on postal?
