Writing the perfect subject line for your job application

What is an email subject line?

An email subject line is the short line of text that appears in a recipient’s inbox and summarises the purpose of an email. An email subject for a job application identifies your name, the role you’re applying for and signals that your message contains an application. A clear and specific subject line improves open rates, supports inbox filtering and helps hiring managers quickly recognise your email.

Example: 
"Sarah Lee – Project Manager Application"
 

What to write in the subject line when sending an email for a Job

So how can you craft a subject line that captures attention and strengthens your job application? Below are practical tips to help you write a clear, professional email subject for your job search:  
 

Be clear and direct 

Hiring managers often spend just six seconds reviewing a CV, and even less time scanning emails.

Your subject line should clearly communicate:

• Your name
• The role you’re applying for
• The purpose of your email

Avoid vague subject lines like “CV for role” or “application for consideration”. Instead, make it obvious what your email contains.

Example:

"Jessica Walter, Marketing Manager Application"

"Jessica Walter, Marketing Manager Interview Follow-Up"

Stay within character and word limits 

Email inboxes typically display only about 60 characters of a subject line, and on mobile devices, this drops to around 25-30 characters. Make the most of the limited space by eliminating unnecessary words and getting straight to the point.

Example:

"Executive Assistant Application - Dave John"

 

Place important words at the front of your email subject

With over 66% of emails being read on mobile devices, it’s crucial to front-load your subject line so the hiring manager will see the most important details. You don’t want key information cut off by the email’s preview function. Get straight to the point by leading with the role or key qualifications.

Example:

"Human Resources Manager, FMCG Experienced
 

Include keywords for search and filtering 

Hiring managers often use filters and folders to manage their inboxes, especially when they’re receiving numerous job applications. 

Including keywords such as:

• Job application
• Application
• Position title
• Reference number

can make your email easier to find later.

These keywords can help your email stand out in a search and ensure it doesn’t get lost.

Example:

"Job Application: Jessica Walter, Marketing Manager"

"Data Scientist Application No. 123456 – John Smith"

 
As Bridget Clarke, Director, Robert Walters Wellington shares:

“You don’t want the hiring manager to spend time opening the email and trying to decode what it is”

 
Clarity saves time and improves your chances.
 

List professional titles or certifications

Your subject line can also be a tool to promote your qualifications, differentiating yourself and catching the hiring manager's attention. If you hold any relevant certifications or titles, acronyms such as MBA, CPA, or Ph.D., consider adding them to help you stand out. This can quickly show hiring managers why you’re a strong candidate. Just make sure to only use it when it's relevant to the role.

 
Example:

"Accountant, CPA – Mark Jones"
 

Avoid using all caps or excessive punctuation 

Using all caps can feel like shouting. Excessive exclamation marks or symbols can appear unprofessional.

Keep your subject line clean and easy to read. Use proper capitalisation and simple separators such as hyphens or colons.

Example:

"CV for Reception Roles – Available Immediately" 
 

Mention referrals if applicable

If you’ve been referred by someone within the company or a mutual contact, make sure to include this information in your subject line. It’s a great way to grab attention and add credibility to your application.

Example:

"Referred by Mark Jones – Engineer Role"

What comes next? Crafting the perfect job application email

Once you’ve nailed the subject line, the next step is making sure the content of your email stands out just as much. Here’s a breakdown of what to include in your job application email to grab the hiring manager’s attention:

Personal greeting: Address the hiring manager by name if possible. Avoid generic greetings like "To whom it may concern."

Introduction: Briefly introduce yourself, mentioning the role you’re applying for and how you found the opportunity. Keep this concise but impactful.

Tailored pitch: Highlight why you're a great fit for the position. Mention key skills, experience, or accomplishments that match the job requirements. Show how you can add value to their team.

Attachments: Clearly mention that your CV and any other required documents (e.g., cover letter, portfolio) are attached. Ensure they are properly named (e.g., "John_Smith_CV.pdf").

Call to action: Politely express your interest in an interview or further discussion. Suggest a time to follow up if appropriate.

Professional closing: Sign off with a formal, yet friendly, closing such as "Kind regards" or "Best regards," followed by your full name and contact details.

By structuring your email this way, you’ll make a strong, professional impression and increase your chances of moving forward in the hiring process.
 

Stand out in your application with the right subject line

Your email subject line may be only a few words long, but it can shape a hiring manager’s first impression of you. A clear, professional and keyword-focused subject line makes it easy for recruiters to identify your application, filter it correctly and prioritise it for review. In a competitive job market, small details like this can set you apart.
