Write one when it adds missing context
A cover letter is valuable when the employer requests it, the application is by email, you are changing role or country, a referral needs context, or your strongest fit is not obvious from the CV.
Do not send a generic letter merely to complete a field. If the letter adds no decision-useful information, improve it or omit it when the process allows.
Read the application instructions first. The required format, language, recipient, and attachment rules take priority over any general template.
Use a four-part decision structure
Name the role, state the strongest fit, prove it with one or two examples, explain the employer connection, and close with a clear invitation to continue the conversation.
The opening should identify the exact vacancy and the reason the reader should continue. Avoid long personal histories before relevance is established.
The middle should connect evidence to the employer's need. The close should be confident and specific without assuming an interview or promising unavailable documents.
- Role and source
- One-sentence fit
- Evidence with context
- Employer-specific close
Replace adjectives with evidence
Words such as passionate, dynamic, and results-driven are weak without an example. Show the decision, contribution, or outcome that earns the description.
Choose evidence that the CV cannot explain quickly: a career transition, a difficult constraint, a reason for targeting this employer, or the connection between two experiences.
Keep claims consistent with the CV and public profile. A polished contradiction is still a contradiction.
Make the final letter easy to trust
Check the employer name, role title, reference number, recipient, language, examples, links, and attachment name. Then remove any sentence that could be sent unchanged to every employer.
One page is a useful discipline for most applications. Shorter is acceptable when the application email itself is the letter.
AI may critique structure or compare the letter with a job description, but the applicant must verify every fact and approve the final wording.
