How to write the email that carries your application

The cover email is the first thing a hiring team reads. It needs a clear subject line, five sentences, and correct attachments.

When you apply by email, the email is the application until someone opens the attachment. Treat it as a short, complete message rather than a note taped to a document.

The subject line

Include the role, and the reference number if the posting has one. "Application: Senior Data Analyst (ref 4182) — Priya Anand" is easy to file and easy to search later.

The body

  • One line naming the role and where you saw it.
  • Two or three lines of your strongest relevant evidence.
  • One line pointing to the attached CV and cover letter.
  • A closing line and your contact details.

Attachments and file names

Send PDFs unless the employer asks for DOCX. Name files so they still make sense in a folder of two hundred others: "Priya-Anand-CV-Senior-Data-Analyst.pdf".

Before you send

Check the recipient, the company name, the role title and that the attachment is the tailored version rather than an older draft. These are the four mistakes that most often undo good work.
