When your email list starts going quiet, that’s not the end, it’s an opportunity. Re-engagement email templates are built to wake up dormant subscribers, spark curiosity, and remind people why they signed up in the first place. Done right, these emails can bring back up to 30% of inactive users without spending a rupee more on acquisition.
And here’s what’s changed: according to email marketing data 2025 from Litmus and Campaign Monitor, global email open rate benchmarks for reactivation campaigns climbed from 17% in 2023 to an average of 21.4% in 2025. Brands that personalize their re-engagement efforts (by name, purchase history, or behavior) consistently outperform those using generic “We miss you” blasts.
Let’s break down the numbers, examples, and insights shaping the best re-engagement email templates in 2025 and what digital marketers and CRM managers can learn from them.
Why Re-Engagement Emails Matter
Customer acquisition costs keep rising. Reactivating an existing subscriber costs roughly 5x less than acquiring a new one. That’s why re-engagement campaigns are one of the highest-ROI plays in retention marketing.
In 2025, the data is clear:
- 45% of inactive subscribers can still be reactivated with targeted messaging (HubSpot, 2025).
- Revenue from reactivated users accounts for up to 18% of total email-driven sales for top e-commerce brands.
At the same time, Apple’s Mail Privacy Protection and Gmail’s image caching have made open tracking less precise. As a result, smart marketers now define “inactive” users using behavioral triggers: no opens or clicks in 90 days, no purchases in 6 months, or abandoned carts without return visits.
What this really means is: to stay profitable and compliant, you can’t just track opens. You have to build intent-based reactivation campaigns that rely on meaningful interactions and accurate CRM segmentation.
What the Data Says: 2024–2025 Benchmarks
Based on aggregated email marketing data 2025 from Campaign Monitor, ActiveCampaign, and Klaviyo, here’s how re-engagement email templates are performing across sectors:
| Sector | Avg Open Rate | Avg Click Rate | Conversion Rate |
| SaaS | 25.6% | 4.3% | 2.1% |
| Retail / E-commerce | 22.8% | 5.7% | 3.8% |
| B2B | 19.3% | 3.4% | 1.9% |
Interestingly, segmenting inactive cohorts differently is now the norm:
- SaaS brands segment by “last login” or “last feature use.”
- E-commerce brands segment by “last purchase” or “cart abandonment.”
- B2B companies rely on CRM activity (no replies, no meetings booked, etc.).
Data from Litmus (2025) shows that reactivation campaigns using dynamic personalization tokens (name, last product viewed, plan type) lift open rates by an average of 26% versus static templates.
Top Performing Re-Engagement Email Templates (With Data Support)
1. The “We Miss You” Template
Why it works: Emotional re-connection + personalization.
Example subject line: “Hey [First Name], still thinking about you.”
- Average open rate: 30%+ when personalized
- Click rate: 4.9%
- Best for: SaaS, subscriptions, content-driven products
What the data shows: HubSpot found that adding personalized subject lines raised reactivation open rates from 18% to 31%. Including a friendly reminder of benefits (e.g., “You still have 3 unused credits”) increases clicks by another 11%.
2. Incentive-Based Offer Email
Why it works: Everyone loves a good deal, if it feels relevant.
Example subject line: “Your 15% comeback code expires tonight.”
- Average open rate: 27.4%
- Click rate: 6.2%
- Best for: E-commerce, DTC, travel, lifestyle
According to Omnisend (2025), free shipping now drives higher reactivation than discount codes, lifting open rates by 8% and conversion by 12%. The reason: price fatigue customers are more likely to engage when the value feels convenient rather than desperate.
3. Behavior-Triggered Recommendations
Why it works: Personalized nudges based on real user data.
Example subject line: “We’ve handpicked these just for you, [Name].”
- Average open rate: 33%
- Click rate: 7.1%
- Best for: SaaS, streaming, e-commerce
These reactivation campaign examples use browsing or usage history to drive curiosity. Brands using behavior-triggered templates report 1.8x higher re-engagement than batch re-sends. AI-powered segmentation tools (like Klaviyo or HubSpot) can now predict which lapsed users are most likely to return.
4. Feedback Request Reactivation
Why it works: Empathy + two-way communication.
Example subject line: “Can we ask one quick question before we say goodbye?”
- Average open rate: 29%
- Response rate: 4.5%
- Best for: SaaS, education, subscription media
When framed as genuine curiosity rather than exit prevention, these emails perform surprisingly well. ActiveCampaign’s 2024 report found that asking for simple 1-click feedback (“Still interested?”) reactivated 22% of subscribers who hadn’t opened in 6 months.
Copywriting and Design Patterns That Work in 2025
The inbox has evolved. With dark mode adoption at over 83% of mobile users, minimal and accessible design is no longer optional, it’s essential.
Here’s what’s working now:
Subject Line Trends That Improve Open Rates
| Tactic | Example | Open Rate Lift |
| Personalization | “Hey [Name], it’s been a while…” | +22% |
| Curiosity | “You won’t believe what’s new since you left.” | +18% |
| Urgency | “Your account will be deleted in 3 days.” | +30% |
| Incentive framing | “Here’s your comeback bonus. ” | +25% |
Design Practices
- Use dark-mode-friendly images and fonts. Test text contrast for accessibility.
- Keep a copy under 80 words above the fold.
- Highlight the CTA button (one only) with strong color contrast.
- Show user-specific content blocks (like recent items or plan status).
According to Campaign Monitor (2025), emails using a single CTA see 42% more clicks than those with multiple links.
Automating and Testing Re-Engagement Campaigns
Automation is where good strategy meets scale. With AI-driven predictive analytics, tools like Klaviyo, HubSpot, and ActiveCampaign can now predict “re-engagement likelihood scores.”
How Automation Boosts Performance
- Predictive send times based on when each subscriber is most likely to open = +13% open rate.
- Dynamic subject line testing automatically promotes top performers.
- Multi-step workflows that shift tone from soft to direct if users stay inactive.
Testing Open Rates Post-Privacy Changes
Since open tracking is less reliable, smart marketers and every leading email marketing agency now measure engagement using:
- Click-to-open rate (CTOR) instead of open rate alone.
- On-site activity or app logins post-email as success signals.
- Predictive engagement scoring via AI models trained on historical patterns.
In short, automation doesn’t just send the right message, it decides when and to whom that message should go.
What Defines a High-Performing Re-Engagement Email in 2025
The best re-engagement email templates share a few consistent traits:
- They use behavioral and contextual personalization instead of bulk messaging.
- They focus on empathy and relevance, not desperation.
- Their design is mobile-first, dark-mode friendly, and CTA-driven.
- They rely on updated engagement metrics that go beyond opens.
With inbox competition rising and privacy rules tightening, the brands that win will be the ones treating re-engagement as a science not guesswork.

FAQ’s
A re-engagement email is a message sent to inactive subscribers to reignite their interest in your brand. It helps you reconnect, reduce churn, and boost retention without extra ad spend.
Most brands run re-engagement campaigns every 3–6 months, depending on engagement cycles. SaaS and subscription brands tend to test shorter intervals since inactivity usually signals churn faster.
According to email marketing data 2025, average open rates range from 20% to 25% across industries, with top-performing campaigns reaching 30% or higher when personalized.
The top performers include “We Miss You” emails, incentive offers, behavior-triggered recommendations, and feedback request templates, all proven to improve open rates and conversions.
Platforms like Klaviyo, HubSpot, and ActiveCampaign use AI and predictive analytics to automate send timing, personalize content, and test templates for better engagement.
Common mistakes include vague subject lines, multiple CTAs, or irrelevant offers. Ignoring mobile optimization or dark-mode readability also hurts engagement and deliverability.
