The short answer
A useful cover letter names the role, connects relevant experience to its needs, and gives a specific reason for your interest. It should add context rather than repeat every resume bullet.
The four jobs your letter needs to do
Think of a cover letter as a short argument for why this application makes sense. The reader should quickly understand which opening you mean, what evidence supports your fit, and why you chose it. Contact details and a greeting help the document function, but the evidence does the persuasive work.
- Opening: identify the role and the relevant connection to your background.
- Evidence: describe one or two examples that support important responsibilities.
- Employer connection: explain a specific, accurate reason the work interests you.
- Closing: express interest in a conversation and provide a clear sign-off.
A simple outline to adapt
Replace every bracketed detail with accurate information. If you cannot explain why a sentence belongs to this employer, make it more specific or remove it.

Choose one example with enough detail
Use an example that proves a capability the employer needs. A customer support applicant might explain resolving a recurring source of confusion; an engineering applicant might explain a design decision and verification. An early-career applicant can use a substantial project or volunteer responsibility.
Do not manufacture a performance percentage to make the paragraph look impressive. Explain the scope, your contribution, and what changed. If the work was collaborative, describe your contribution rather than claiming the entire team's result as your own.
Check the document and the submission field
Follow the employer's instructions on file type, length, and whether the letter belongs in an attachment or text field. A short online answer does not need a postal-style address block unless requested. For a formal attachment, keep the layout consistent with your resume.
Before submitting, verify the employer and role names, remove placeholders, and read the exported file. Use the letter to clarify a relevant career change or motivation where helpful; do not bury the main point under a long personal history.
