17 Quick Ways to Write Re-engagement Email Subjects

Tone: Conversational, Warm, Curious

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

This Subject Line Can Also Be:

• Wondering if [job title] at [company] is still on your mind?
• Noticed you paused, so I paused too. Want to chat?

Tone: Friendly, empathetic

“Still Dreaming” shows that you remember their wish list. Soft language, such as “Let’s chat,” keeps the door open.

Use case: A lead clicked on a listing three months ago but then went quiet.

Tips to Use

• Reference one past property they viewed in the body.
• Offer a brief market update PDF to restart dialogue.

Type: Re-engagement, Interest-Based Retargeting

Tone: Respectful, Curious, Subtle

You’re gently tapping to see if the reader is still interested. This works well for following up with leads, offering product trials, or encouraging visits to the pricing page.

Use it when someone shows strong intent, but doesn’t convert. This shows that you noticed without pressuring them.

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?

Type: Retention, Re-engagement, Unsubscribe Prevention

Tone: Bittersweet, Calm, Thoughtful

This subject line is like a soft invitation. You’re not begging or chasing. But you’re giving one last reason to stay. Subject lines that hinted at closure (“final,” “last,” “before you go”) can increase open rate and conversion rates than neutral reminders.

Use this in the last email of a re-engagement flow. This is typically after 3 to 4 emails over 30–60 days.

Make sure the email body includes an incentive, a quick recap of what the user is missing, or a simple reactivation button.

This Subject Line Can Also Be:

• If this is goodbye, let’s part with a gift.
• Before you disappear, check this out.

Retention Email Example

Subject: One last thing before we say goodbye…

Hi [first name],

We noticed you haven’t been around lately. That’s totally okay! But before we stop checking in on you, we wanted to say thanks. Whether you stayed for a week or a year, we’re glad you joined us.

If there’s anything we could have done better, we’d love to know. If you’re thinking about coming back, here’s a 15% discount on your next order—just in case.

Reactivate now

All the best,
The [Company] Team

Type: Re-engagement

Tone: Helpful, low‑pressure

Adding the recipient’s pain point turns a classic quick question subject line into a mini value reminder.

Send it to leads who went quiet after initially showing interest.

Type: Retail purchase anniversary, re‑engagement.

“Toast” paints a mental image, guiding readers to celebration. This subject line sets a clear value, which lifts open intent.

Pair this line with a hero image of the product the customer bought last year.

Type: Re-engagement Price Drop

Tone: curious, warm

After 30-60 days of silence, use this price drop subject line. Inside, highlight three or more relevant products with their new prices. Then, invite feedback to maintain engagement.

Add a short explanation of why they’re receiving this email to avoid any misunderstandings.

This subject line acknowledges the reader’s past disappointment with the question, “Missed out before?” Then, it announces the product’s availability.

It’s perfect for cart abandoners or wish list users.

Tone: Conversational, empathetic

Tips

• Pair with dynamic images of the exact item they viewed.
• Offer a small incentive, like free shipping, to sweeten the deal.

Recap subject lines build brand trust and encourage re-engagement. If you include session recordings, takeaways, or bonus material, the open rate tends to spike again.

Type: Post‑Event Follow‑up

Tone: Appreciative, helpful

Sometimes a ticket hangs around with no clear resolution. You resolved the issue on your end, but the customer hasn’t responded.

This subject line serves as a gentle follow-up. Unlike “We’re closing your ticket,” it feels like an invitation, not a dismissal. You’re offering closure, not forcing it.

Tone:

Proactive, Helpful, Thoughtful

This re-engagement email subject line appeals to the reader’s ego by suggesting that their account is still valuable.

The verbs “saved” and “catch” sit close, so the message feels urgent yet welcoming.

Win‑back campaigns average 29% open rate, topping the 21.5 % general mark.

A quick question at the end nudges action without pressure. 

Type: Re-engagement, Win‑back, Marketing

Tone: Friendly, curious, supportive

When to Use

Send after 60 days of silence. Earlier feels pushy, later risks churn.

Tips

• Add a personalized preview text: “Hey [Name], your dashboard still holds your stats.”

Tone: Encouraging, incentive‑driven, upbeat

Why It Works

“Still on board?” checks loyalty, while “fresh perk” promises immediate value.

The whole subject line stays under 50 characters, which helps mobile previews.

Attach the perk in the email body: a small credit or cheat sheet to justify the open.

When to Use

Great for SaaS renewals or memberships with lapsing engagement.

Tips

• Use merge tags to insert the plan name, e.g., “[Plan] perk just landed.”
• Remind them of unused features to spark curiosity.

Type: Re-engagement, Product Update, Educational

Tone: Informative, gentle, optimistic

Why It Works

You acknowledge the absence politely and then introduce the novelty. The comma maintains the flow of the sentence, preventing an abrupt stop.

Adding “new” piques curiosity and signals low risk. Subscribers know they won’t be subjected to a sales push alone.

When to Use

Use this email subject line for inactive subscribers after a major feature release or content refresh.

Tips

• Preview text: “A two‑minute read on the feature everyone asked for.”
• Include a quick video or GIF demo to lower learning barriers.

Type: Re-engagement, E‑commerce, Incentive

Tone: Urgent, value‑packed, direct

Why It Works

You identify the problem as “silence” and deliver the solution of an “exclusive offer.”

The overall email open rate is 39%, but re-engagement emails linked to discounts can outperform when the sense of urgency is clear.

Words like “exclusive” and “comeback” tap FOMO without sounding desperate, and “claim” frames the offer as already theirs.

When to Use

This subject line is perferct for carts abandoned 30+ days or when seasonal stock rotates.

Tips

• Set a 48‑hour expiry in the email to encourage swift action.
• Cite how many users redeemed similar offers last month to show social proof.

Type: Re-engagement, Discount, Personalization

Tone: Warm, incentive‑led, personal

Why It Works

“Reconnect” is a subtle request, while “save 10%” quantifies the benefit.

Discounts that match user preferences can increase the rate, especially when paired with “Favorites.”

The line keeps things personal without oversharing data by promising relevance—favorites.

When to Use

Fire this during an annual sale or anniversary event to make the 10% feel special, not generic.

Tips

• Show two recommended products in the email preview to spark recognition.
• Include a countdown timer GIF for urgency, but keep the aesthetic uncluttered.

This one taps into that post-Thanksgiving regret. It speaks to people who didn’t shop on Friday but still want a win.

“Missed Black Friday?” makes the email feel like a second chance. Then I anchor the present-tense offer with “just dropped.”

Timing this line Monday morning works best. Make sure to reinforce the message with a “still time” tone in your hero header.

Type

Cyber Monday, Re-engagement, Broad Appeal

Tone

Encouraging, opportunistic

This subject line can also be

• You skipped Friday. But Cyber Monday’s here
• Cyber Monday: your second chance at 60% off
