  • Personalized address and greeting
  • Clear purpose statement
  • Relevant product/service highlights
  • Evidence of reliability (certifications, case studies)
  • Call to action and invitation for next steps
  • These components are proven, on average, to increase response rates by 27% for B2B communications.
