Hey [Name], your PTO misses you (really)
Tone: Humorous, Warm, Friendly
You know that colleague who never takes a day off? This subject line is perfect for them, offering a gentle and humorous reminder.
It’s best used quarterly to remind your team about their unused vacation time. Send it around burnout-heavy seasons, such as project wrap-ups or year-end sprints.
It’s humorous but sincere, reinforcing a culture that genuinely encourages rest.
Guess who just got promoted? (Hint: It might be you.)
Tone: Playful, Intriguing, Motivational
This one instantly sparks curiosity. Although promotions are exciting, they are often delivered dryly. Here, however, you flip the script by adding intrigue.
We changed something big (and we think you’ll love it).
Tone: Teasing, Positive, Conversational
Policy updates usually trigger eye rolls, but what if employees expected something positive instead? Whether it’s improved parental leave, remote work perks, or flexible hours, this approach generates anticipation rather than dread.
Just ensure the email content delivers the on its promises—don’t let this be clickbait. Pair it with a brief summary of what’s new and why it’s beneficial.
What should we keep, change, or stop doing?
Tone: Collaborative, Transparent, Curious
This subject line for HR’s feels refreshingly honest. You’re giving employees explicit permission to critique openly, making feedback feel less like a formality and more like genuine collaboration.

You reached out to someone, or maybe they applied a while ago. Then, silence. This line is your way back in.

Can we talk about what’s not working?
Tone: Empathetic, Open-ended, Slightly vulnerable
This one’s raw and intentional. It’s the kind of message that makes a team member stop scrolling. Because it feels personal, not procedural.
Use it when you need honest feedback, especially when there’s tension in the air—maybe after a tough change, a dip in morale, or poor unfavorable results from an engagement survey.
Your feedback is safe with us, seriously
Tone: Reassuring, Sincere, Trust-building
Let’s be honest—survey fatigue is real. And “Please complete this 5-minute survey” just doesn’t cut it anymore. This line is all about safety. More specifically, it’s about psychological safety.
Use this line when you’re launching an engagement survey, pulse check, or sensitive topic like DEI or exit feedback.

Let’s Wrap Up, Schedule Your Exit Interview
Tone: Friendly, action‑oriented.
The phrase “Let’s Wrap Up” hints at closure and partnership. “Schedule Your Exit Interview” clearly states the request. You set expectations and provide next steps all at once. People respond better when they know exactly what you need and why it matters.
Tips
Include a calendar link in the body. If you mention specific slots, use square brackets: “[Monday at 2 PM]” so the reader can click to confirm.

Tone: Encouraging, respectful.
Starting with “We value your thoughts” sets a tone of genuine interest. Adding “Exit Interview Inside” tells the reader exactly what the email is about.

Tone: Formal, considerate.
Putting “Your Final Feedback Session” at the beginning signals seriousness, and mentioning the company reminds the reader of the shared history. This format makes it feel like an exclusive meeting invitation rather than a generic survey, raising the perceived importance and respect.
Tips
- Add a clear deadline in the pre‑header.

Who would you recommend for [opportunity]?
Type: HR, Partnership, Business
Tone: Professional, Curious
This question-style email subject line hits two goals at once: asking for a referral and showing you value the person’s judgment.
I often suggest this subject line for HR outreach or partnership scouting. It invites participation and frames the referral as a chance to help someone else.
By keeping it open-ended, you make space for the reader to recommend more than one name. Very handy when hiring, looking for speakers, or sourcing collaborators. It feels personal without overstepping.
Your documents are due by [date]
Tone
Formal, deadline-focused
Why this line works
This one’s plain, but powerful. When you set a due date in the subject line, you create clarity.
You avoid back-and-forth. You avoid ambiguity. And for internal operations, whether onboarding new hires or chasing contracts you save hours when people know exactly what to do and when.
You’re also signaling seriousness without panic.
Bonus tip
Pair this with a progress checklist inside the email body. You reduce confusion and limit the number of replies asking “what’s missing?”
