IMPLEMENTATION TIPS
- 1
Pass structured prospect data (name, company, role, recent trigger event) rather than raw text — structured input produces more focused personalization and is easier to validate for completeness before the API call.
- 2
Limit personalization to the opening 1–2 sentences and then write the value proposition generically: prospects read to the end only if the opening hooks them, and over-personalized emails feel intrusive beyond the opener.
- 3
Generate 3 subject line variants per email and A/B test them — subject lines account for 50% of open rate variance, making them the highest-leverage variable to optimize in your outreach sequence.
