Why your business emails keep going to spam

You're not sending spam. So why do your emails keep ending up in the junk folder, even for people who know you by name?

Updated · senderframework.com

Signs this is happening to you

  • Customers tell you they found your email in spam or junk.
  • Replies have slowed down, but nothing else has changed.
  • Your emails land in spam for some people and not for others.
  • Even emails to people who have written to you before go to junk.

Why are my emails going to spam when I'm not a spammer?

Most people think spam is about words. Don't say "free", don't use too many capitals. That matters a little. What matters far more is proof.

Before your email is read, the inbox checks whether it can prove the email came from you. Without that proof, even a perfect email from a real business looks just like a scam. So it goes to spam.

Why does it keep happening?

The proof lives in settings most business owners never see. They were set up once, by someone, and then left alone. Each new tool you send from, each change of email company, can quietly break them.

You won't get a warning. The only sign is that replies slow down, and people say "I didn't see your email".

Will it fix itself?

No. The longer it goes on, the less the inboxes trust your name. A little spam today can turn into a lot of spam next month.
