Email Deliverability Best Practices

  1. Authenticate your domain (SPF, DKIM, DMARC)
  2. Don’t buy email lists — kills reputation
  3. Re-engage or remove inactive subscribers
  4. Keep complaint rate under 0.1%
  5. Send from a real domain (not gmail.com)
  6. Monitor deliverability metrics weekly

Common Email Automation Mistakes

  1. Treating automation like broadcast — automate based on behavior, not just time
  2. Over-emailing — list fatigue kills engagement
  3. Bad subject lines — open rates suffer
  4. No segmentation — same email to everyone is wasted spend
  5. Not testing — A/B test every major campaign
  6. Ignoring deliverability — emails in spam = wasted spend
