Why Your Business Email Goes to Spam and How to Fix Itلماذا يذهب بريد شركتك إلى الرسائل المزعجة وكيف تصلح ذلك

Email deliverability is a technical problem with a technical solution. Rewriting the message rarely helps if the domain is not authenticated.

Receiving mail servers ask three questions about every message: is the sender allowed to send for this domain, has the message been altered, and does this domain have a history of sending junk. If you cannot answer the first two with a DNS record, you are judged on suspicion.

1. SPF: who may send for your domain

An SPF record lists the servers permitted to send email using your domain name. If you send from your hosting mail server plus a newsletter platform, both must be listed in one single SPF record. Two separate SPF records break authentication entirely.

2. DKIM: proof the message was not altered

DKIM adds a cryptographic signature to every outgoing message and publishes the matching public key in DNS. The receiving server verifies the signature and knows the content really came from you.

3. DMARC: what to do when a check fails

A DMARC record tells receiving servers how to treat messages that fail SPF or DKIM, and where to send reports. Start with a monitoring policy, read the reports for a few weeks, then tighten to quarantine or reject once legitimate senders are all authenticated. DMARC is also what stops criminals sending fake invoices in your company name.

4. Reverse DNS and a clean IP

The IP address your mail leaves from should have a matching reverse DNS entry and must not appear on public blacklists. This is the responsibility of your hosting provider, and it is a good reason to avoid the cheapest shared servers, where one careless neighbour can affect everybody.

5. Sending behaviour

• Never send bulk marketing from your normal mailbox: use a proper mailing platform with unsubscribe links
• Avoid attaching large files; send a link instead
• Keep a clean list and remove addresses that bounce
• Avoid subject lines written entirely in capitals or full of exclamation marks
• Make sure the visible from address matches the sending domain

Authenticate first, then worry about wording. Ninety percent of spam folder problems are DNS problems.

How to check where you stand

Send a message to a test address on a different provider and read the message headers. They will show pass or fail for SPF, DKIM and DMARC. If any line says fail or none, that is your starting point. Most fixes are three DNS records and take less than an hour to apply, then up to a day to propagate.
