Dear Hiring Manager,

Your Customer Success Manager opening caught my attention because of how clearly your brand speaks to its customers, and the growth you have posted over the past year. I have spent four years in onboarding and retention for B2B SaaS, and I would like to bring that experience to Northwind Goods.

Most recently, I cut time-to-value for new customers from 45 to 21 days and reduced churn in my segment by a third. I build success plans, run health scoring and partner with sales on renewals.

Your posting asks for customer success, onboarding and churn reduction, which is the part of the work I do best, and I would bring the same care to health scores and renewals. I want to help your customers get lasting value from your product, and I would welcome the chance to talk about how my experience fits your plans for the team.

Thank you for your time and consideration.

Sincerely,
Alex Morgan

It reuses the posting's words. Skills like customer success, onboarding, churn reduction appear the way an employer would write them, which helps both applicant tracking systems and a skimming recruiter.
It ends with a next step, politely, in two lines.
