Thank You Email Subject Line After Interview

Why the Subject Line Matters

Hiring managers receive dozens of emails daily. Your post-interview thank you email competes with meeting invites, project updates, and other candidate communications. A clear subject line ensures your email gets opened promptly rather than sitting in the inbox unread.

The best subject lines are direct, professional, and immediately communicate the purpose of the email. Creativity is fine, but clarity always wins in professional communication.

Best Subject Line Formulas

Formula 1: Direct Thank You

The simplest and most effective approach. It works in every situation.

• "Thank you — [Position Title] interview"
• "Thank you for your time today"
• "Thank you for the [Position] conversation"
• "Thank you, [Interviewer Name]"

Formula 2: Meeting Reference

References the meeting directly, making it easy to identify.

• "Great speaking with you today"
• "Following up on our conversation"
• "Enjoyed our discussion about [Position]"
• "Re: [Position Title] — thank you"

Formula 3: Enthusiasm-Forward

Shows genuine excitement about the role.

• "Excited about the [Position] opportunity"
• "Thank you — excited about [Company Name]"
• "Looking forward to next steps — [Position]"

Formula 4: Value-Add

Hints at additional value in the email body. Use this with unique thank you email approaches.

• "Thank you + a thought on [topic discussed]"
• "Thank you — and a resource on [topic]"
• "Following up with the [document/idea] I mentioned"

Subject Lines by Interview Type

Phone Screen

• "Thanks for the call today"
• "Thank you for the phone conversation"
• "Great talking with you about [Position]"

Video Interview

• "Thank you for the video call"
• "Great meeting you virtually"
• "Thank you for the [Position] interview"

In-Person Interview

• "Thank you for meeting with me today"
• "Great visiting your office — thank you"
• "Thank you for the tour and interview"

Second or Final Round

• "Thank you for having me back"
• "Even more excited after round two"
• "Thank you for the opportunity — [Position]"

Subject Lines to Avoid

• "Hi" or "Hello": Too vague. The hiring manager has no idea what the email is about before opening it.
• "Please read": Demanding and unprofessional. It implies urgency where there is none.
• Blank subject line: Some email clients flag blank subjects as suspicious. Never skip the subject line.
• ALL CAPS: Reads as shouting. Keep it sentence case or title case.
• Overly creative: "You won't believe what I just thought of!" is not appropriate for a professional follow-up.
• Too long: Keep subject lines under 60 characters. Many email clients truncate longer subjects, especially on mobile devices.

Pro Tips for Subject Lines

• Include the position title when the interviewer handles multiple roles. It immediately provides context.
• Reply to the interview confirmation thread if you want. Using "Re:" keeps your email in context of the existing conversation.
• Match the interview's formality level. Casual startup? "Great chat today" works. Law firm? "Thank you for the interview" is better.
• Personalize when possible. "Thank you, Sarah" feels warmer than "Thank you for the interview."
