Small business email landing in spam? Here is how to fix it

Few things hurt a small business more quietly than email that never arrives. You send a quote, the customer never sees it, and you lose the job without ever knowing why. If your messages are landing in spam, the fix is usually simpler than you think.

Why good email gets flagged

Mail providers like Gmail and Outlook are aggressive about filtering, because most email in the world is junk. To decide whether to trust you, they check whether your domain has proven that it really sends the mail it claims to. If those proofs are missing or set up wrong, your legitimate email gets treated as suspicious.

Those proofs have three names: SPF, DKIM, and DMARC. They sound technical, but the idea behind each is plain.

SPF, DKIM, and DMARC in plain English

• SPF is a list of who is allowed to send email for your domain. It tells the world, “these servers can send mail as us, no one else.”
• DKIM is a tamper-proof signature on each message. It lets the receiving server confirm the email really came from you and was not altered along the way.
• DMARC is your instruction for what to do when a message fails those checks. It also sends you reports so you can see who is sending mail in your name, including impersonators.

Set all three up correctly and you tell every mail provider that your domain is trustworthy. Skip them and you are gambling with every message.

The other things that quietly hurt deliverability

Authentication is the big one, but a few habits matter too:

• Sending from a free address like a gmail.com account instead of your own domain.
• A domain that is brand new with no sending history.
• Buying lists or emailing people who never opted in, which generates spam complaints.
• Sloppy formatting, broken links, or spammy subject lines.

How to check where you stand

You can look up your own domain’s records, but the results are easy to misread. The safest first step is to send a test message to an address on a different provider and check whether it lands in the inbox or the spam folder. If it is going to spam, your authentication almost certainly needs work.

Getting it fixed for good

SPF, DKIM, and DMARC live in your domain’s DNS settings, and a small mistake can make things worse, including blocking your own mail. It is worth getting right once rather than guessing.
