Hi.
Email from a companies domain email adress's goes straight into gmail spam folders . Its only an issue sending to gmail adresses.

Gmail marks the email with : "Why is this message in spam? It is similar to messages that were identified as spam in the past."

even a test email with no signatures or attachments goes to spam
domain & servers IP not on any blacklists (that I know of, Ive checked several)
spf is setup
PTR is not setup : issues with the ~ISP~ being just a reseller of another ISP's services : I have tried to get PTR setup correctly, so far nothing
As recommended , I used Gmails postmaster tools : pretty much worthless , didnt help at all
Gmail offers a form for BULK email senders: these emails are not bulk emails , just 'normal' business emails to clients

Any advice on how to deal with gmail to stop this domains email's ALL being treated as spam ?

Do you have SPF, DMARC, DKIM, or anything else setup?

Best bet would be to move away from a reseller service to something like Office 365, Google Apps or Zoho Mail. You then control your email settings...

Other than this nothing much can be done if you have no control over the setup.

The inner workings of Google are a bit of a mystery, but setting a PTR and using both SPF and DKIM should be sufficient. I have those set up (no DMARC) and my delivery appears reliable, at least to my own GMail account, and people do seem to reply to me.

You can check in GMail to make sure SPF and DKIM validations were successful. Worth checking in case they are set up incorrectly, or mail is going through a system which breaks the DKIM validation.

Otherwise, if there is no PTR at all for your IP, that's the most likely cause. Filtering on PTR not matching seems to be largely a thing of the past thankfully - worse still were the RFC violating systems that blocked mail delivery based on this, which is prohibited.

Another possibility is your IP range being blacklisted due to other users. Not much you can do about that unfortunately, short of requesting a new IP or switching ISPs.

Thanks for the replies

only SPF is setup. Having issues getting PTR setup , due to internet service being from a reseller (A VOIP phone service seller who bundled internet services into the deal).
So cant contact the actual ISP directly .

Not using ISP's email services. Email is sent from companies SBS server

Obviously something triggered this domains email to all be marked as spam in gmail.
Im trying to find how to get gmail to reset this .

From what Ive googled with others having this issue, DKIM PTR etc didnt help.

Cheers

Fix these first. You will need DKIM and SPF configured even if there is another contributing issue. You may get away without setting the PTR, but other mail servers may reject on this even if Google is satisfied.

One option could be to set up a third party SMTP smarthost and relaying the mail from the SBS exchage out through that. They usually have good step by step guides about how to setup DKIM, SPF, PTR etc to ensure mail is delivered correctly.

If one or more people tag the email as spam in Gmail, will that not mean that gmail may see the senders IP as a source of spam? Not sure if Gmail uses RBLs, but I do know that it isn't uncommon for me to find legit emails from companies in the spam folder.

Not necessarily "one or more people". It will be a percentage of the emails sent from a domain but one report alone won't be the cause.

As stated above, Google's workings are a black box. Google won't just trigger on the IP address, they will also analyse the headers & content.

You can try to get all the current Gmail users that receive your email to mark the emails as "NOT SPAM", thereby untraining Google's algorithms. Get your recipients to set up a rule to "never mark as SPAM" your emails. You would want it to look something like this:

Anecdotally speaking, just reading the subject lines & deleting the emails seems to have taught Google that I do not want "these" emails & started marking them as SPAM.

Yeah I wondered about this. I get emails that are notifications of various things and just getting the email is enough for me to know that something has happened, I don't need to read the actual message. I wondered if deleting these messages without reading them would signal to Gmail that they were unwanted but so far I haven't noticed Gmail doing this.

Looks like setting the PTR correctly has fixed the issue.

I know for sure after a few days sending test emails

Go the extra mile and put some time into using a smart MTA, setup PTR, SPF, DKIM and DMARC. Then get a service like DMARC Analyzer or Valimail to monitor results.
