The best way to improve your SpamAssassin Score is to follow clean emailing practices:

  • Clean your mail list to avoid bounce. Don't use bought mail lists.

  • Set up authentication protocols (SPF, DKIM and DMARC).

  • Monitor blacklisting/greylisting.

  • Send relevant content to avoid being reported as spam by your recipients.

  • Use List-Unsubscribe Header to make things simple for your subscribers.

  • Take care of URLs in emails (avoid broken links and shortened URLs).

  • Avoid using shared-IP to fully control your sender reputation.

  • Keep steady sending volume, avoid huge gaps in email activity.

  • Avoid using spammy keywords in subject line and body content.

  • Segment your mail list to make sure that your content is adapted to recipients.

  • Warm-up your inbox and domain before mass sending.
