Email subject line examples

Still curious about [product or service name]?

Type
Win back, SaaS, Trial Re-engagement
Tone
Conversational, Direct, Lightly Curious

This win back subject line gently reopens the conversation. No pressure. No gimmicks. Just a question.

This Subject Line Can Also Be:

  • Forgot something? [product name] is still waiting.
  • Your progress is saved. Keep going?

20% off. Just because you’re missed

Type
Retention, Win back, Ecommerce
Tone
Incentive-based, Friendly, Promotional

Direct and heartfelt. Adding a discount can increase clicks by up to 40% in win-back sequences. But what makes this work is the emotional cue.

Use this subject line if the user hasn’t bought something from your site or visited it in the last 60 days. The main body of the email should be gentle and not pushy.

This Subject Line Can Also Be:

  • Your loyalty means the world. Here’s 20% off.
  • Still here, still saving a spot for you.

We miss you. Ready to come back?

Type
Retention, Win back, Customer Loyalty
Tone
Warm, Personal, Slightly Emotional

Simple. Honest. You aren’t hiding the intent. Saying “We miss you” makes people feel emotional. The phrase “Ready to come back?” sounds casual and not pressuring.

Try it if a customer has gone quiet for 30+ days, especially if they used to contact you regularly.

This Subject Line Can Also Be:

  • Still thinking about us?
  • Your seat’s still saved.
  • We noticed you’ve been away…

Optional but helpful: quick exit interview link

Type
Soft opt-in, low-pressure exit interview
Tone
Neutral, transparent, helpful.

When employees feel like they have a choice, it reduces pressure and builds trust. “Optional but helpful” reminds the person that you appreciate their feedback, but you won’t be upset if they don’t say anything.

This kind of subject line is especially useful for companies that value independence and self-direction.

We’d love 5 minutes of your insight, [Name]

Type
Time-specific, respectful
Tone
Polite, quick, personal.

Numbers help people estimate effort. “5 minutes” feels like a reasonable amount of time, and the name makes it personal. When employees feel swamped during offboarding, specific details like this one can make it easier for them to adjust.

Before you head out, your voice matters

Tone
Grateful, warm, validating.

The phrase “your voice matters” is especially popular in inclusive, people-first companies. It can boost trust, especially with teams that value psychological safety.

Tips

Keep the email short and include a clear example of how employee feedback has shaped something real in the past. That helps close the loop.

What worked, what didn’t? Help us grow

Tone
Honest, open, appreciative.

Questions like “What worked, what didn’t?” are emotionally safe because they balance critique with praise.

Pair it with a body paragraph that explains how past feedback has led to real change. That proof builds trust.

Subject Line: Wrap things up? A few parting thoughts from you

Quick check‑in before your last day, [Name]

Tone
Friendly, informal, caring.

This line sounds like a colleague reaching out, not a policy being enforced. That softness encourages engagement.

Here are some tips:

Use this only if you’ve had some rapport with the employee. If it’s a more corporate context, you can play around with the line a bit more and add context in the email body.

Reminder, Complete Your Exit Interview by [Date]

Tone
Polite, time‑sensitive.

“Complete Your Exit Interview by [Date]” clearly defines the objective and deadline for completing the exit interview. Deadline cues get things moving, and square brackets prepare the reader to see a real calendar date.

Tips

  • Send this reminder 48 hours before the original deadline, and again 24 hours before if needed.
  • In the email body, restate the link and thank them in advance.
  • Keep phrasing consistent so the thread stays clean.

Your Final Feedback Session with [Company]

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.
  • If you offer virtual or in‑person options, mention that in the opening line.

That way, employees know you respect their schedule and preferences.

Email Example:
