Why Your Emails Are Hitting Spam
If your clients aren't receiving your emails and they are landing in the Junk folder, your domain's DNS records are likely improperly configured. Modern email providers like Gmail and Office 365 now rigorously check three specific security protocols to verify your identity.
The Big Three Protocols
1. SPF (Sender Policy Framework)
SPF acts like a guest list for a party. It's a DNS record that lists all the IP addresses and servers (like Mailchimp, Google Workspace, or Zendesk) that are officially allowed to send emails on behalf of your domain. If a spammer tries to send an email from a server not on this list, it gets blocked.
2. DKIM (DomainKeys Identified Mail)
DKIM is a digital wax seal. It adds a cryptographic signature to every email that leaves your server. When the receiving server gets the email, it checks the public key in your DNS to verify the signature. This ensures the email wasn't tampered with in transit.
3. DMARC (Domain-based Message Authentication)
DMARC is the instruction manual for the bouncer. It tells the receiving server exactly what to do if an email fails the SPF or DKIM checks. Without DMARC, the receiving servers have to guess. With DMARC set to "reject" or "quarantine", you maintain total control over your domain's reputation.
