Marcus Vance
Chief Marketing Officer, GrowthWave Media
700 Congress Ave, Austin, TX 78701

Dear Mr. Vance,

I am excited to submit my application for the Digital Marketing Specialist position at GrowthWave Media. GrowthWave's bold, story-driven campaigns have consistently set the benchmark for modern brand marketing, and I would love to contribute to your continued momentum.

Over the past five years at Lumina Digital, I managed multi-channel acquisition campaigns across search, social, and email with annual budgets exceeding $1.2M. By implementing automated funnel segmentation and conversion rate optimization (CRO) tests, I grew qualified lead generation by 65% while reducing customer acquisition costs by 22%.

I am confident that my analytical rigor combined with creative storytelling will deliver immediate ROI for GrowthWave Media's client portfolio. I appreciate your time and welcome the opportunity to discuss this further.

Warm regards,

Sophia Martinez

Why this letter works

  • Sets scale immediately with a $1.2M multi-channel budget.
  • Pairs a growth metric (65% more qualified leads) with an efficiency metric (22% lower CAC).
  • Closes on client ROI, which is what an agency CMO is hiring for.

Make it yours

  1. Swap in the hiring manager's name and one specific thing about the company you actually admire.
  2. Replace the numbers with your own results. Keep one growth metric and one efficiency or quality metric.
  3. Keep it under one page, then check your resume against the same job with the ATS checker.
