If your business emails keep landing in junk or spam folders, it is almost always down to email authentication, not the words in your emails. Receiving servers like Gmail and Outlook cannot verify your mail is genuine, so they play it safe and filter it. The good news: it is fixable, usually with a few DNS changes.
SPF tells receiving servers which systems are allowed to send email for your domain. If it is missing, incomplete, or has too many lookups, your mail fails the check and gets filtered.
DKIM adds a cryptographic signature that proves your email was not tampered with in transit. Without it, providers trust your mail less and are quicker to junk it.
DMARC ties SPF and DKIM together and tells servers what to do when mail fails. Left at p=none it does nothing, so your domain looks unverified.
If your sending IP or domain has a history of spam, or a marketing platform was added incorrectly, providers filter your mail by default until reputation recovers.
Run the free check above to see which of these applies to your domain. It returns a plain-English score and a prioritised list. Most fixes are DNS changes your IT team can make in an hour or two, and delivery usually improves within 24 to 48 hours as the changes propagate.
Rarely. Junk filtering for business email is usually about authentication (SPF, DKIM, DMARC) and sending reputation, not the words in your message. Fix the authentication and delivery normally recovers.
Once the DNS records are corrected, most improvements show within 24 to 48 hours as changes propagate. Reputation recovery, if that is the issue, can take a little longer.
The check tells you exactly what is wrong in plain English. The fixes are DNS changes, which your IT team or provider makes. You do not need to understand the detail, just hand them the list.
