What to Look For

  1. Test subject line generation quality (this drives open rates)
  2. Look for personalization capabilities (merge fields, tone adjustment)
  3. Check if the tool can generate full sequences (not just individual emails)
  4. Prioritize tools that can adapt tone between cold outreach and warm nurture
  5. Verify the output doesn't trigger spam filters (avoid hype words)
