Your emails go to junk in Outlook and Hotmail

Gmail users get your email. But people on Outlook, Hotmail or a work Office account keep finding you in their junk folder. Why the difference?

Updated · senderframework.com

Signs this is happening to you

  • People on Outlook, Hotmail or Live find you in junk.
  • Outlook shows a question mark where your picture should be.
  • Large companies, who mostly use Microsoft, never seem to reply.
  • Your email reaches Gmail fine, so you assumed all was well.

Why does Outlook put my email in junk?

Every big email company has its own rules. Microsoft is one of the strictest. If it can't prove your email came from you, it often sends it straight to junk, even when Gmail lets it through.

So a business can look fine to half its customers and be in the junk folder for the other half.

What does the question mark in Outlook mean?

When Outlook shows a question mark instead of a picture or initials, it is telling the reader it could not confirm who sent the email. It is a quiet warning to your customer: be careful with this one.

Why does this hit business customers hardest?

Most large companies, schools and councils run on Microsoft. If your email lands in junk there, it is your biggest clients who miss it.
