Emails going to spam

Why are my emails going to spam?

Most spam-folder problems come from a mix of technical setup, message content, sender reputation, and list quality. SamuelGuard helps separate the fixable issues from the guesswork.

Your domain authentication may be weak

Mailbox providers want proof that your email is allowed to use the domain in the message. Missing or broken SPF, DKIM or DMARC can make even legitimate email look risky.

  • SPF should include the service that sends your mail.
  • DKIM should sign messages with your sending domain.
  • DMARC should exist on the visible From domain.
  • Alignment should make sense between From, DKIM, and return-path domains.

The email may look too promotional

Messages packed with hype, all caps, too many links, shortener URLs, or image-only content are more likely to look like the emails filters were designed to catch.

  • Use calm subject lines that describe the message.
  • Keep links useful and transparent.
  • Include readable text, not only images.
  • Avoid manipulative phrases like guaranteed, urgent, or act now.

Your sender reputation may be hurting delivery

If people ignore, delete, complain, or bounce your email often enough, mailbox providers can become less willing to place future mail in the inbox.

  • Send to people who expect your email.
  • Clean dead or mistyped addresses.
  • Watch sudden blacklist changes.
  • Warm new sending domains and IPs carefully.

The message may be missing trust signals

Business emails should look consistent, expected, and easy to understand. Marketing emails also need proper unsubscribe paths and honest sender identity.

  • Use a recognizable From name and domain.
  • Make the reason for the email clear quickly.
  • Include unsubscribe headers for marketing-style mail.
  • Make sure replies and links go to trustworthy domains.
FAQ

Common questions

Why do Gmail or Outlook send my emails to spam?

They combine many signals, including authentication, reputation, engagement, content, and recipient history. A spam test helps find visible problems before you chase the wrong fix.

Can one bad subject line send email to spam?

Sometimes it contributes, but spam placement is usually a combination of signals. Fix technical authentication first, then improve content and sending practices.
