I write subject lines for passive candidates as a quick decision aid. The candidate should know why I am writing and what kind of message is inside without feeling that I am using a trick. A specific role, work area, referral, or relevant project is usually more useful than a vague phrase such as "exciting opportunity."
Subject line patterns I use
Role plus company:
- [Role] focused on [specific work] at [Company]
- [Role] opportunity with [Company] in [location]
Relevant experience:
- Your experience with [specific skill] and a [Role] opening
- A [specific project] conversation for [First Name]
Low-pressure invitation:
- Open to a brief conversation about [work area]?
- Comparing notes on [function] at [Company]
Referral:
- [Referrer Name] suggested I contact you
- Introduction from [Referrer Name] about [Role]
Hard-to-fill role:
- Building [specific capability] at [Company]
- [Role] leading [specific outcome], [location or remote]
I use the candidate's name only when the rest of the subject is clear. Personalization without context can look automated.
Examples by outreach situation
For a senior engineering candidate, I might use "Your work scaling event systems and a platform lead role." For a marketing candidate, "Leading lifecycle measurement at [Company]." For someone referred by a trusted colleague, I use "A quick introduction from [Name]." For a candidate who was previously interested, I use "Following up on [Role] from [month]."
The subject should match the body. If I mention a specific project in the subject, I include the accurate connection in the opening sentence. If the role is confidential, I use a work-area description and avoid revealing information that the company has not approved for sharing.
Subjects I avoid
I avoid "You are a perfect fit," "Career opportunity," "Urgent," and "Can we talk?" because they provide little context or create pressure. I also avoid exaggerated claims about impact, culture, or growth that the message cannot support. Excessive punctuation and all caps make a personal note look like a campaign.
A simple test
Before sending, I ask whether the candidate could answer three questions from the subject and preview: Who is contacting me? Why me? What is the next step? If the answer is no, I revise the subject or the opening rather than adding more hype.
I keep a small record of subjects used by role and audience, but I judge them by qualified replies and useful conversations, not opens alone. A subject line earns its place when it helps the right person make an informed choice.
