Are your emails ending up in spam?

Content-related reasons:

  1. Suspected spam subject lines: ."
  2. Poorly formatted content:
    • Emails with large images, little text, or poorly formatted HTML can trigger spam filters.
  3. URLs in the email:
    • Links to untrustworthy or unverified websites can be marked as spam.

Technical reasons:

  1. Missing SPF/DKIM/DMARC entries:
    • These authentication protocols are important to mark your emails as secure.
  2. IP address on blacklist:
    • If the IP of your email provider is on a "blacklist", your emails will likely end up in spam.
  3. Shipping via free email services:
    • Business communication via free email services such as GMX, Yahoo, or Gmail can appear unprofessional.

Behavioral reasons:

  1. High email volume:
    • Too many emails in a short period of time can be considered as spam.
  2. Low interaction rate:
    • If recipients rarely open or respond to your emails, spam filters may be blocking them.
  3. Emails are being marked as spam:
    • If many users mark your emails as spam, it will have a negative impact on your sender reputation.

Other reasons:

  1. Inconsistent sender information:
    • The "From" name should match the content and purpose of the email.
  2. Missing unsubscribe option:
    • A clear unsubscribe link is legally required and necessary.
  3. Spam traps:
    • Sending emails to spam trap addresses accidentally can damage your reputation as a sender.

To avoid spam filters:

  • Improve your content: Compose professional and clear emails.
  • Authenticate your emails: Implement SPF, DKIM, and DMARC for your domain.
  • Ask customers for whitelisting: Customers should add your address to their address book or safe sender list.
