Why Your Emails Go to Spam (And How to Fix It)

You send an important email. It lands in spam. Here is why — and the fix takes 10 minutes.
The three records that matter
- SPF: lists which servers may send email for your domain. Without it, anyone can forge your address.
- DKIM: cryptographically signs your emails so receivers can verify they were not tampered with.
- DMARC: tells receivers what to do with mail that fails SPF/DKIM (quarantine or reject).
How to set them up
Your email provider gives you the exact TXT records to add. In your K Host DNS zone editor, add all three — propagation takes minutes to hours.
Beyond DNS
- Do not send bulk mail from a brand-new domain — warm it up gradually.
- Keep bounce rates under 2% and spam complaints under 0.1%.
- Always include a working unsubscribe link in marketing mail.
