The ten strategies

  • Segment your list — relevance drives opens; send by industry, behavior, and lifecycle stage.
  • Write subject lines that earn the open — specific, benefit-led, and honest.
  • Personalize beyond the first name — reference behavior, role, or interest.
  • Lead with value, not the ask — teach first, sell second.
  • Use a single clear CTA per email.
  • Automate lifecycle flows — welcome, nurture, re-engagement, and post-sale.
  • Optimize for mobile — most emails are read on a phone.
  • Test and iterate — A/B test subject lines, send times, and CTAs.
  • Keep your list clean — prune inactive contacts to protect deliverability.
  • Measure what matters — track clicks and conversions, not just opens.

Automation is the multiplier

The biggest gains come from automation. A well-built welcome series, lead-nurture sequence, and re-engagement flow work 24/7 without anyone hitting send. That’s where tools like HubSpot and Zapier turn email from a chore into a system.

Want these flows built and connected to your CRM? That’s our specialty.
