There are several ways to help avoid getting the email you send blocked including

  • Send plain text email
  • If you send HTML email use a high text to image ratio
  • Do not send bursts of similar email to large email providers
  • Verify your SPF records and DKIM signatures do not have any errors
  • Do not send email to addresses that bounce with permanent 5xx SMTP error codes
  • Do not send email from blacklisted IP addresses
  • Personally address and resolve all spam complaints
