Preventing Sent Going To Spam

Server Config
1

I have added SPF text, DKIM CNAMEs and DMARC txt to domain name.

What else can I do to prevent emails being sent from domain going into people’s junk/spam folders from my genuine website.

Many thanks

Not having content that looks like spam?

Just because the email legitimately comes from your site, doesnt mean it isnt spam.

Did you check whether your domain name, IP address, and email server are blacklisted? See https://multirbl.valli.org/

Nothing in blacklists - all good

5

Do you have any details of a message that bounced back or ended up in a junk folder ?

6

What as in content you mean??

I am assuming that by your question, you had issues with emails ending up as spam or bouncing back. Analyzing the details, as shown in the sample below, might help you identify the issue.

Do you receive and study DMARC reports? They may give you some clues to what happens to your mail, though it’s not always very specific information.

I am not getting bounce backs, so I cannot analyise any header information.

I did receive this today.

I know you added DKIM records by did you check those settings for arcadeoperator.co.uk ?

12

No I did not.

The settings have overwhelmed my experience on this to be honest.

Extract of Perplexity’s answer (see here for the complete message) :

All 100 messages from IP 52.212.19.177 failed both SPF and DKIM alignment checks.

The DMARC policy for arcadeoperator.co.uk is set to “quarantine”, so these emails were delivered to recipients’ spam/junk folders, not their inboxes.

SPF Result: softfail
This means the sending server was not explicitly authorized in the SPF record, but the policy is not as strict as a hard fail. Softfail typically marks the message as suspicious but does not outright reject it.

DKIM Result: fail
The DKIM signature did not validate or was not aligned with the domain.

In short:
All emails from the specified IP failed authentication and were quarantined (sent to spam) due to failing both SPF (softfail) and DKIM checks. This indicates either unauthorized sending or a need to update your domain’s authentication records
