What's a good open rate for email campaigns?

The Honest Answer: Open Rate Benchmarks Are Inflated — Here's What the Numbers Really Say

Here are the numbers you came for — and the catch that makes them worth questioning before you celebrate or panic.

The benchmarks, straight up: According to Klaviyo's analysis of over 205,000 brands, the average campaign open rate sits at 31%, automated flows average 32.2%, and the top 10% of performers reach roughly 45%. MailerLite's 2025 benchmark data shows an even wider spread — from 30.10% in travel and transportation to 55.71% in religion, with a 43.46% overall average.

Industry matters enormously. Mailchimp's industry breakdown puts Non-Profits at 40.04%, Education + Training at 35.64%, Business + Finance at 31.35%, and Ecommerce at just 29.81%. A 32% open rate is crushing it in ecommerce and underperforming in nonprofit fundraising — context changes everything.

Here's the quick reference:

• Average campaign open rate: 31% (Klaviyo)
• Average automated flow open rate: 32.2% (Klaviyo)
• Top 10% performers: ~45% across both campaigns and flows
• Industry range: 30.10% to 55.71% (MailerLite 2025)

Now the contrarian punch: your dashboard is lying to you. Since 2021, Apple's Mail Privacy Protection has automatically marked emails sent to Apple Mail clients as opened — whether or not a human ever saw them. MailerLite is blunt about it: "real open rates are lower than the metrics you see in your dashboard." Salesforce goes further, declaring open rates "no longer a reliable metric" and recommending click-through rate and click-to-open rate instead.

Klaviyo's Lizzie Davey offers a middle ground: open rate "can still be a good directional metric" — useful for spotting trends, useless for precision. The inflated numbers don't just flatter you; they distort year-over-year comparisons and can trigger false alarms (or false confidence) about subject line performance.

This is why at GrowthPros we treat email as one channel in a sequence, not the scoreboard itself. Email works best as backup to faster channels — a five-minute AI voice or SMS follow-up reaches people who never open anything, and roughly 78% of buyers choose whoever responds first. An open rate can't measure that. A booked call can.

So if you're asking "is my open rate good?" — the honest answer is that the question itself is flawed. Good compared to a benchmark that's inflated by Apple's proxy opens? Good in an industry that ranges from 30% to 55%? The number is a starting point for diagnosis, never the target.

Stop Optimizing a Broken Metric: Why CTR and CTOR Reveal the Truth

Open rates look impressive on a dashboard, but Apple's Mail Privacy Protection quietly inflates them by marking emails as opened without any human action. Salesforce, MailerLite, Klaviyo, and Mailchimp all flag the same problem: the metric no longer reflects genuine interest. A reliable engagement signal has to survive privacy changes, and that means shifting to clicks.

• Click-through rate (CTR) = (unique clicks ÷ delivered emails) × 100 — 150 clicks from 1,000 delivered = 15% CTR
• Click-to-open rate (CTOR) = (unique clicks ÷ unique opens) × 100 — 20 clicks from 50 opens = 40% CTOR

Salesforce benchmarks put a "good" CTR for general marketing at 2–5% and a strong CTOR above 20%. MailerLite's Duncan Elder puts it bluntly: click rate is now the most accurate engagement indicator because it doesn't rely on tracking opens. Klaviyo's data across 205,000 brands shows automated flows deliver 3× higher click rates (5.58% vs. 1.69%) and 13× higher placed-order rates than one-off campaigns, while generating nearly 41% of revenue from just 5.3% of sends.

The same logic applies to lead follow-up. GrowthPros builds every lead delivery around a five-minute AI response window — voice, SMS, and email — because contacting a lead that fast makes contact roughly 100× more likely than waiting thirty minutes. A smaller, engaged list that gets instant, relevant follow-up outperforms a bigger list that never opens. The metric that matters isn't how many people see your subject line; it's how many take the next step.

The Data Case for Automated Follow-Up: 3x Clicks, 13x Orders From 5% of Sends

The subject line gets the open. Timing gets the revenue.

Klaviyo's analysis of over 205,000 brands reveals a striking imbalance: automated flows represent just 5.3% of total email sends yet generate nearly 41% of all email revenue. These sequences deliver 3x higher click rates (5.58% vs. 1.69%) and 13x higher placed order rates (2.11% vs. 0.16%) than one-time campaigns, despite nearly identical open rates of 32.2% and 31% respectively. The advantage isn't in getting seen — it's in showing up at the right moment with the right message.

• Automated flows drive 3x higher click rates than campaigns
• They generate 13x more orders per send
• Just 5.3% of sends produce nearly 41% of revenue

Artisan's research on cold outreach reinforces the pattern: two to three follow-ups is the ideal range, emails between 25 and 50 words perform best, and interest-based CTAs like "Would you like to learn more?" generate a 30% response rate — double the alternatives. The data converges on a simple truth: consistent, timely follow-up beats heroic subject lines every time.

This is exactly why GrowthPros builds AI-powered follow-up into every lead we deliver. Our system responds across voice, SMS, and email within five minutes — the window where contact likelihood is roughly 100x higher than at thirty minutes. Whether it's a fresh exclusive lead or a dormant contact from your own CRM, the sequence fires automatically, qualifies intent, and pushes a warm conversation into your CRM before the prospect cools off.

Why Speed Beats Craft: Instant AI Follow-Up vs. the 30-Minute Email

Even the most meticulously crafted email sequence loses to speed when it comes to lead conversion. Contacting a lead within five minutes makes contact roughly 100x more likely than at thirty minutes, and about 78% of buyers choose whoever responds first. This isn’t about polishing subject lines or perfecting copy—it’s about being first in the inbox, voice mail, and SMS thread when intent is highest.

Instant AI-powered follow-up within minutes of lead generation dramatically increases contact likelihood—making outreach roughly 100x more effective than delayed follow-up. While email open rates vary widely—from 29.81% in ecommerce to 55.71% in religion—these metrics are increasingly distorted by Apple’s Mail Privacy Protection, which automatically marks emails as opened without user interaction. As a result, even a “perfect” email with a 45.8% open rate (the top 10% for automated flows) fails if it arrives after the lead has already engaged with a competitor.

• Automated email flows generate 3x higher click rates and 13x higher placed order rates than one-time campaigns, despite representing only 5.3% of total sends.
• The top 10% of automated flows achieve a 45.8% open rate and a 10.48% click rate, far outperforming standard campaigns.
• AI-powered follow-up systems can 2–3x reply rates when combined with proper prompts and tools, turning speed into measurable engagement.

GrowthPros builds this immediacy into every lead—fresh or reactivated—by delivering AI voice, SMS, and email follow-up inside a five-minute window, 24/7. This isn’t an upsell; it’s the core of how leads are qualified and routed into your CRM. When response time dictates 78% of outcomes, slow email follow-up isn’t just ineffective—it’s where lead ROI quietly dies. The real advantage isn’t in the email’s craft. It’s in how fast it arrives.

What to Do Monday Morning: Benchmark, Automate, and Reactivate

Start your Monday with data, not guesswork. Benchmark your email performance against real industry numbers—like the 31.35% average open rate for Business + Finance or the 29.81% for Ecommerce—to set realistic goals based on your sector. Then stop chasing opens and start measuring what matters: aim for a click-through rate of 2–5% and a click-to-open rate above 20%, metrics proven more reliable than inflated open rates due to Apple’s Mail Privacy Protection according to Salesforce.

Replace static targets with action. Put automated flows on every new lead—welcome sequences, nurture series, or post-engagement triggers—since Klaviyo found automated flows generate 3x higher click rates and 13x higher placed order rates than one-time campaigns, despite being just 5.3% of total sends per their analysis of over 205,000 brands. These flows work because they’re timely, not because they get opened more often.

Finally, reactivate what you already own. Run a multi-channel AI sequence—SMS first, then voice, then email—on your dormant opted-in list. Typically, 8–15% of those contacts re-engage, and at a cost 60–80% below acquiring a new lead per GrowthPros’ reactivation model. Every lead, whether fresh or revived, gets AI voice, SMS, and email follow-up within five minutes, with consent records attached—because contacting a lead within that window makes outreach roughly 100x more likely than waiting thirty minutes as their data shows. Cap it with a 15-minute qualification call to set real numbers, not placeholders.

• Benchmark against your industry’s real open rates (e.g., 31.35% for Business + Finance)
• Replace open-rate goals with CTR (2–5%) and CTOR (>20%) targets
• Deploy automated flows on every new lead—they drive 3x higher click rates
• Reactivate dormant lists with AI—SMS, voice, email—8–15% re-engage at 60–80% below new-lead cost
• Follow up every lead in <5 minutes with AI voice, SMS, email—and book a 15-minute qualification call
