Cover letters are not outdated, but they are no longer required for every application. Surveys of hiring managers consistently show that most still read cover letters when included, even when a posting marks them as optional — but the impact is uneven, and a generic letter adds far less value than a tailored one. The short answer: write one when the role is competitive, your résumé doesn’t tell the full story, or you’re changing careers; skip it for high-volume, fully automated applications where none is requested.
Key facts
- Hiring manager surveys commonly report that a large majority still read cover letters when submitted, even at companies that don’t require one.
- A tailored, role-specific cover letter has a measurably larger impact on callback rates than a generic one — customisation is what does the work.
- Not all surveys agree: some more recent business-leader surveys report far lower read-rates, so treat any single statistic with some caution.
- Cover letters matter most for career changers, candidates with employment gaps, and highly competitive or mission-driven roles.
Do Hiring Managers Actually Read Them?
The data here is genuinely mixed, which is worth acknowledging rather than glossing over. Several hiring-manager surveys report that the large majority of hiring managers read most cover letters they receive, and that many expect one even when a listing marks it as optional. Other, separately conducted surveys of business leaders report a much lower read-rate, with a significant share skipping cover letters entirely.
The likely explanation for the gap is who’s being asked. Recruiters doing high-volume initial screening are far more likely to skip cover letters than hiring managers making a final decision on a shortlist — several studies draw exactly this distinction. In practice, the further along in the process you are, the more likely someone is reading closely.
When a Cover Letter Is Worth Writing
When communication and cultural fit matter
A concise, well-structured cover letter demonstrates writing ability and professionalism in a way a résumé alone can’t — useful for client-facing, communications, or leadership roles.
When you’re changing careers
Your résumé shows where you’ve been. A cover letter is the place to explain where you’re going, and connect past experience to the value you’d bring in a genuinely different role.
When you have an employment gap
A short, honest explanation of a gap — framed around what you learned or how you grew — tends to land better than leaving the gap for a hiring manager to guess about.
When you’re applying to a mission-driven organisation
A genuine cover letter signals that you understand and care about the organisation’s purpose, not just the role itself.
When You Can Reasonably Skip It
If a job posting explicitly states a cover letter is optional and the process is high-volume and largely automated, skipping it is unlikely to hurt your chances — particularly for entry-level or high-turnover roles where speed of application matters more than narrative. The exception is when you have something specific to explain (a gap, a career change, a non-obvious fit) that the résumé can’t cover on its own.
Getting the Most Out of a Cover Letter
- Keep it to half a page — concise and specific outperforms long and generic.
- Tailor it to the role. Customisation is consistently the biggest driver of impact across the available data, far more than length or formatting.
- Don’t use it to repeat your résumé. Use it to explain the parts your résumé can’t: motivation, transition, or context.
- A strong cover letter can’t rescue a weak résumé — get the résumé right first, then let the cover letter add the narrative.

FAQ
Are cover letters still necessary in 2026?
Not for every application, but they still matter for competitive roles, career changes, employment gaps, and situations where a résumé alone doesn’t tell the full story. Most hiring-manager surveys show a majority still read them when included.
Should I write a cover letter if it’s marked optional?
Usually yes, particularly for roles you’re genuinely competing for. Multiple surveys report that hiring managers still expect one even when a listing marks it optional, and a tailored letter is one of the few free ways to stand out.
How long should a cover letter be?
Half a page is the general guideline — long enough to add real context, short enough that it will actually get read in full.
Can a good cover letter make up for a weak résumé?
No. A cover letter adds context and narrative, but it can’t substitute for relevant experience or a well-structured résumé. Get the résumé right first.
Is a generic cover letter better than none at all?
Only marginally. The data suggests most of the benefit of a cover letter comes from tailoring it to the specific role — a generic, copy-pasted letter adds little value over skipping it entirely.
