Sarah Lindqvist
Senior Data Analyst, Merchandising, Tailwind Traders
Dear Sarah Lindqvist,
I'm applying for the Senior Data Analyst role on Tailwind Traders' merchandising team. At Northfield Retail I built a demand forecast in Python that reduced stockouts by 17% across 120 stores, and your posting's focus on inventory planning is exactly the work I want to keep doing.
The forecast mattered because people used it. Before it, store managers planned from 30 separate weekly spreadsheets. I replaced them with a single Tableau dashboard that 85 managers now open every week, and I added automated SQL checks upstream that cut reporting errors by 70% — so the numbers in the dashboard are ones people trust.
I also look for money hiding in the data. Comparing regional prices against competitor and cost data, I found a pricing gap that added $1.2 million in annual margin once the team adjusted it. Earlier, at Streamly, I built a churn model that flagged at-risk subscribers; the retention offers it triggered saved about 4% of monthly revenue.
I'd be glad to walk you through how I built the forecast and what I'd look at first in Tailwind's merchandising data. Thank you for your time.
Sincerely,
Daniel Kim

Tips for your data analyst cover letter.
01
Name the decision your work changed
Analysts are hired for decisions, not dashboards. Say who used your work and what they did differently.
02
Keep tools to one line
Mention SQL, Python or Tableau where they fit the story; the resume can carry the full list.
03
Quantify carefully
Use numbers you can explain in an interview, and say how you measured them if it isn't obvious.

What should a data analyst cover letter focus on?
One or two analyses that changed a business decision, who used them, and the result. Tools matter less than impact and communication.
Should I include a portfolio link?
If you have a relevant, public project or dashboard, yes — link it once with a sentence on what it shows.
