The Problem: Why Open Rates Are Misleading in 2026
The average email open rate for 2026 is often cited as a key performance indicator, but relying on it alone can lead to flawed decisions—especially for winback campaigns where genuine re-engagement matters more than inflated metrics. Apple's Mail Privacy Protection continues to distort open rate data by preloading content for Apple Mail users, making reported opens unreliable as a measure of actual human engagement. For service businesses using winback emails to reactivate dormant customers, this distortion risks misallocating resources toward campaigns that look successful on paper but fail to drive real-world actions like bookings or replies.
According to Klaviyo's 2026 benchmarks, the average campaign open rate across all industries is 31%, with automated flows slightly higher at 32.2%. However, these figures are acknowledged by the same source as not being "100% effective" due to Apple's MPP artificially inflating opens for users with enabled privacy settings. HubSpot's analysis confirms this impact, noting that open rates rose "18 points (to over 40%)" shortly after MPP launched and that Apple Mail represents 46% of email clients, meaning nearly half of all tracked opens may not reflect genuine user interaction. Mailerlite similarly states that "Apple Mail Privacy Protection automatically marks emails sent to Apple Mail clients as opened," reinforcing that real engagement is likely lower than reported.
For winback campaigns—where the goal is to reignite relationships with past customers—open rate becomes an even more dangerous vanity metric. A high open rate might suggest visibility, but it doesn't confirm whether the recipient read the message, considered the offer, or took action. As HubSpot's marketing lead observes, "I've seen high opens lead to zero engagement, and average numbers drive major results. The difference? Context, timing, and strategy." This is especially true for service businesses like those CallMyCustomers supports, where a winback email's success hinges on prompting a reply, call, or booking—not just an inbox appearance. Prioritizing metrics like click-through rate or reply rate offers a clearer signal of genuine interest, helping businesses avoid the trap of optimizing for opens while missing the mark on reactivation.
The Solution: Focus on What Actually Drives Winback Success
The Solution: Focus on What Actually Drives Winback Success
Chasing open rates alone won’t tell you if your winback emails are working—especially in 2026, where privacy changes have made that metric increasingly unreliable. Klaviyo’s 2026 benchmarks show an average campaign open rate of just 31%, a figure that reflects the distorting effect of Apple’s Mail Privacy Protection rather than true engagement.
What actually matters is whether recipients take action after opening. Click-through rate (CTR) and click-to-open rate (CTOR) provide a clearer picture of real interest, since they aren’t inflated by automated opens. Mailerlite confirms that click rate is currently the most accurate indicator of email newsletter engagement precisely because it doesn’t rely on tracking opens. For winback campaigns, this shift in focus helps businesses identify which messages truly resonate and drive behavior.
Automated winback flows outperform one-off campaigns across every engagement metric. Klaviyo reports that automated flows achieve a 32.2% average open rate and deliver roughly 3x higher click rates than campaigns—5.58% versus 1.69%. Even more compelling, flows generate about 13x higher placed order rates, turning re-engagement into measurable revenue. This aligns with HubSpot’s finding that automated workflows can generate up to 30x more revenue per recipient than broadcast emails.
For service businesses like those CallMyCustomers works with—HVAC, dental clinics, salons, and more—this means designing winback sequences that trigger based on inactivity, not blasting generic offers. A well-timed flow might start with a service reminder, follow up with a limited-time incentive, and end with a review request—all approved by the business owner and routed directly into their booking process.
- Use Klaviyo’s 31% benchmark as a realistic baseline for 2026 winback email campaign performance
- Prioritize click-through rate (CTR) and click-to-open rate (CTOR) over open rate as primary success metrics
- Implement automated winback flows rather than one-off campaigns for significantly higher conversion potential
By focusing on what drives actual clicks and conversions—not just opens—businesses can turn dormant customers into booked appointments with messaging that feels useful, not pushy. Every script, offer, and message is approved by the client before sending, ensuring brand consistency while automation handles the scale. This approach doesn’t just reactivate customers—it rebuilds relationships that lead to repeat work, season after season.
Implementation: How to Apply This to Your Service Business Winback Strategy
The 2026 benchmark of 31% average open rate from Klaviyo's analysis of 205,000+ brands gives service businesses a realistic baseline, but the real opportunity lies in what happens after the open. Automated flows consistently outperform one-off campaigns, delivering 32.2% average open rates and roughly 13 times higher placed-order rates. For winback outreach, that difference translates directly into booked appointments rather than vanity metrics.
- Benchmark against your industry: Hardware & home improvement campaigns average 30.9% open rates, while Health & beauty sits at 30.5% for both campaigns and flows
- Structure winback as an automated flow — not a single blast — to capture the 3x higher click rates flows generate over campaigns
- Lead with subject lines that ask a question or include a number; HubSpot data shows questions lift opens up to 50% and numbers add 17%
- Track click-through and click-to-open rates as primary KPIs; Mailerlite identifies these as the most reliable engagement signals post-MPP

Beyond the Open: Turning Benchmarks Into Booked Jobs
The 2026 average email open rate of 31% is a useful starting point, but it's a noisy signal. With Apple's Mail Privacy Protection inflating opens across nearly half of all email clients, a high open rate tells you very little about whether a dormant customer actually read your message, considered your offer, or picked up the phone. What the data consistently shows is that clicks and conversions are the metrics worth optimizing for, and that automated flows outperform one-off campaigns by wide margins — roughly 3x on click rates and 13x on placed order rates. For service businesses, the takeaway is simple: build winback outreach as a structured flow, measure actions instead of opens, and keep every message genuinely useful.
