If you’ve ever sent a quote, an invoice, or an appointment reminder and had a customer say “I never got it” — only to find it sitting in their spam folder — you’re not alone. For small businesses in Frederick County, business emails landing in spam is one of the most common (and most annoying) email problems we see. The good news: it’s usually fixable, and the fix is simpler than you’d expect.
Why it happens
When your email arrives at a customer’s inbox, their email provider runs a quick background check: Is this email really from who it claims to be from? Think of it like a bouncer checking ID at the door. If your domain can’t prove its identity, Gmail, Outlook, and Yahoo are more likely to toss your message into the spam folder — or reject it outright.
There are three small settings that make up that “ID check.” They live in your domain’s DNS settings (the technical control panel behind your website name), and many small businesses never had them set up:
- SPF — “Which servers are allowed to send email for us?” This is a list of the mail servers that have your permission. If your business sends email from Microsoft 365, your website’s contact forms, and your accounting software, all of them need to be on the list. Anything missing looks suspicious.
- DKIM — “A digital signature proving this email wasn’t tampered with.” This adds a hidden electronic signature to every email you send. If the signature doesn’t match when the email arrives, the receiving provider gets suspicious.
- DMARC — “Here’s what to do if the first two checks fail.” This tells receiving providers whether to deliver, quarantine, or reject emails that fail the identity check — and it can send you a report showing who’s trying to send email as your business. That last part is also your early warning system for spoofing, where scammers forge your address to trick your customers.
Without these three, you’re basically sending mail without a return address — and spam filters treat it accordingly.
Why small businesses are hit hardest
Big companies have IT departments that set this up years ago. Small businesses usually have email working “well enough” — messages send, messages arrive — so nobody touches the settings. Then one day your invoices start going to spam, or worse, a scammer sends fake emails from your address and your customers blame you. DMARC reports are often the first time a business owner realizes someone has been impersonating their domain.
How to check and fix it
Here’s the practical path:
- Check your status. There are free online tools that scan your domain and tell you whether SPF, DKIM, and DMARC are set up correctly. (Search “DMARC check tool” and use one from a reputable vendor.) It takes about 30 seconds and just needs your domain name.
- Get them added. If any of the three are missing, they need to be added to your domain’s DNS records. If a vendor or web host set up your domain, you (or your IT person) will need access to wherever your DNS is managed — often your domain registrar like GoDaddy or your website host.
- Don’t copy random records from the internet. SPF and DMARC records have to match your actual email setup. A misconfigured record can cause more delivery problems than you started with.
- Start DMARC in “report only” mode. This is the safe way to roll it out: it sends you reports without blocking anything, so you can see what’s really happening before you tell providers to start rejecting suspicious mail. After a few weeks of clean reports, you can turn the enforcement up.
For most small businesses, this is a one-time project — set it up correctly once and it keeps working in the background.
When to get help
If your customers keep missing your emails, if you’ve ever received a bounce-back saying your message was rejected, or if you suspect someone is sending email that looks like it’s from your business, it’s worth having an IT professional look at your domain’s email setup. Getting SPF, DKIM, and DMARC right takes knowledge of your mail providers and your DNS host, and a mistake in the wrong place can take your email offline entirely.
