Email Open Rate Statistics

Open rates measure the percentage of delivered emails that are opened by recipients. While Apple’s Mail Privacy Protection has impacted the accuracy of open rate tracking since 2021, it remains a widely used directional metric.

Industry Average Open Rate (2026)
Education 30.2%
Government & Non-Profit 29.8%
Healthcare 28.1%
Real Estate 27.4%
Financial Services 26.8%
Professional Services 26.3%
Retail / E-Commerce 24.5%
Technology / SaaS 24.1%
Travel & Hospitality 23.8%
Media & Entertainment 23.2%
F&B / Restaurants 25.6%
All Industries Average 25.8%

The all-industry average open rate for 2026 is 25.8%, up slightly from previous years due to improvements in list hygiene practices and sender authentication protocols (DMARC, DKIM, SPF). Education leads with a 30.2% open rate, while media and entertainment sits at the lower end at 23.2%.

Key open rate statistics:

Statistic Value
Average open rate (Asia-Pacific region) 25.4%
Average open rate (Singapore) 25.8%
Emails with personalised subject lines +26% higher open rate
Emails with emojis in subject lines +15% higher open rate (consumer), -5% (B2B)
Optimal subject line length 30-50 characters
Impact of preview text optimisation +10-15% open rate lift
Re-engagement email open rate 12-14%

Personalised subject lines boost open rates by 26% on average, making personalisation one of the highest-impact optimisation tactics available. Subject lines between 30-50 characters perform best, as they display fully on both desktop and mobile email clients. Preview text (the snippet visible below the subject line) provides an often-overlooked opportunity for a 10-15% open rate lift when optimised.

Click-Through Rate Benchmarks

Click-through rate (CTR) measures the percentage of email recipients who click at least one link within the email. It is a more actionable metric than open rate because it indicates genuine engagement with your content.

Industry Average CTR (2026) Average CTOR (2026)
Education 4.1% 13.6%
Government & Non-Profit 3.8% 12.8%
Healthcare 3.5% 12.5%
Real Estate 3.1% 11.3%
Financial Services 3.3% 12.3%
Professional Services 3.2% 12.2%
Retail / E-Commerce 2.8% 11.4%
Technology / SaaS 3.0% 12.4%
Travel & Hospitality 2.6% 10.9%
F&B / Restaurants 2.9% 11.3%
All Industries Average 3.2% 12.1%

The all-industry average CTR is 3.2%, while the click-to-open rate (CTOR), which measures clicks as a percentage of opens rather than total deliveries, averages 12.1%. CTOR is considered a more accurate measure of content engagement because it removes the variable of whether the email was opened.

Additional CTR statistics:

Statistic Value
Emails with a single CTA vs multiple CTAs +28% higher CTR for single CTA
Emails with personalised content +41% higher CTR
Segmented campaigns vs non-segmented +50% higher CTR
Emails with video thumbnail +65% higher CTR
Plain text vs HTML emails (B2B) Plain text: +18% higher CTR
Button CTA vs text link CTA Button: +32% higher CTR

Segmented campaigns deliver 50% higher CTR than non-segmented broadcasts, making segmentation one of the most impactful email optimisation strategies. Emails with a single, clear CTA achieve 28% higher CTR than those with multiple competing calls to action, reinforcing the importance of focused messaging. Video thumbnails in emails boost CTR by an impressive 65%, highlighting the power of multimedia content in email.

Conversion Rates by Industry

Conversion rate measures the percentage of email recipients who complete a desired action after clicking through, such as making a purchase, signing up, or submitting a form.

Industry Average Email Conversion Rate (2026)
E-Commerce (Promotional) 1.8%
E-Commerce (Abandoned Cart) 4.9%
SaaS / Software (Trial Sign-up) 2.4%
Financial Services 1.6%
Professional Services (Lead Gen) 2.1%
Education (Enrolment) 2.8%
Healthcare (Appointment) 3.2%
Travel (Booking) 1.4%
F&B (Reservation/Order) 2.6%
All Industries Average 1.9%

The all-industry average email conversion rate is 1.9%, though this varies dramatically based on the conversion action and email type. Abandoned cart emails achieve the highest conversion rates at 4.9%, making them one of the most effective email types for e-commerce businesses. Healthcare appointment booking emails also perform strongly at 3.2%, driven by the high intent of recipients already engaged with a healthcare provider.

Conversion rate benchmarks by email type:

Email Type Average Conversion Rate
Abandoned cart recovery 4.9%
Welcome series (email 1) 3.8%
Post-purchase follow-up 3.1%
Browse abandonment 2.7%
Re-engagement / win-back 1.2%
Newsletter (promotional) 1.1%
Product launch announcement 2.3%
Seasonal promotion 2.0%

Automated, behaviour-triggered emails consistently outperform manual broadcast campaigns. Welcome emails convert at 3.8%, post-purchase follow-ups at 3.1%, and browse abandonment at 2.7%. These figures underscore the importance of investing in email automation as part of a comprehensive email marketing strategy.

Best Send Times and Frequency

Send time and frequency significantly impact email performance. While optimal timing varies by audience, industry data provides useful starting points.

Metric Optimal Value (2026)
Best day for open rates (B2C) Tuesday and Thursday
Best day for open rates (B2B) Tuesday and Wednesday
Best time for open rates (Singapore) 10:00 AM – 11:00 AM SGT
Secondary peak time (Singapore) 8:00 PM – 9:00 PM SGT
Worst day for email performance Saturday
Optimal email frequency (B2C) 2-4 emails per week
Optimal email frequency (B2B) 1-2 emails per week
Frequency at which unsubscribes increase 5+ emails per week
Brands sending personalised send-time optimisation 18%

In Singapore, the optimal email send time is between 10:00 AM and 11:00 AM SGT, when recipients have settled into their workday and are actively checking emails. A secondary peak occurs at 8:00 PM – 9:00 PM SGT, when consumers check personal emails during evening leisure time.

Tuesday and Thursday are the best-performing days for B2C emails, while Tuesday and Wednesday work best for B2B. Saturday consistently shows the weakest performance across both segments.

Email frequency is a balancing act. B2C businesses achieve the best results with 2-4 emails per week, while B2B companies perform optimally at 1-2 emails per week. Sending more than 5 emails per week significantly increases unsubscribe rates and spam complaints, regardless of content quality. Only 18% of brands currently use personalised send-time optimisation, which adjusts delivery timing based on each recipient’s historical open patterns, representing a significant opportunity for early adopters.

Mobile vs Desktop Email Opens

The device on which emails are read has significant implications for design, content length, and call-to-action placement.

Device Share of Email Opens (Global) Share of Email Opens (Singapore)
Mobile 61% 64%
Desktop 28% 26%
Tablet 8% 7%
Webmail 3% 3%
Mobile Email Statistic Value
Emails deleted if not mobile-optimised 70%
Users checking email on mobile first thing in the morning 58%
Optimal email width for mobile 320-480 pixels
Mobile users who prefer shorter emails 73%
Impact of mobile-responsive design on clicks +15%
Top mobile email clients (Singapore) Apple Mail (48%), Gmail (38%)

In Singapore, 64% of emails are opened on mobile devices, above the global average of 61%. This mobile-first reading behaviour means email design must prioritise mobile responsiveness. A staggering 70% of users delete emails that do not display well on mobile, making responsive design a non-negotiable requirement.

Apple Mail is the dominant mobile email client in Singapore at 48%, followed by Gmail at 38%. The prevalence of Apple Mail is significant because Apple’s Mail Privacy Protection pre-loads tracking pixels, which inflates reported open rates. This is why click-through rate and conversion rate are increasingly more reliable performance indicators than open rate for Singapore audiences.

Mobile-responsive email design delivers 15% more clicks than non-responsive templates. Key mobile optimisation practices include single-column layouts, large touch-friendly buttons (minimum 44×44 pixels), concise copy, and images that load quickly on mobile connections.

Email Automation Statistics

Automated email campaigns triggered by user behaviour consistently outperform manually sent broadcasts, making automation a cornerstone of effective email marketing.

Automation Statistic Value (2026)
Automated email revenue share 31% of total email revenue
Automated email open rate vs manual 70% higher
Automated email CTR vs manual 152% higher
Businesses using email automation 68%
Welcome email open rate 58%
Abandoned cart email recovery rate 8.3% of abandoned carts recovered
Abandoned cart email revenue per email SGD 5.81
Post-purchase email repeat purchase rate 12%
Re-engagement win-back success rate 14%
Average number of automated flows per business 5.2

Automated emails generate 31% of total email revenue despite comprising a much smaller share of total email volume. Compared to manual broadcasts, automated emails achieve 70% higher open rates and 152% higher click-through rates. These dramatic performance differences are driven by the timeliness and relevance of triggered messages.

Welcome emails achieve an exceptional 58% open rate, making them the highest-performing email type. Abandoned cart emails recover 8.3% of abandoned carts, generating an average of SGD 5.81 in revenue per email sent. Post-purchase follow-up emails drive a 12% repeat purchase rate, demonstrating the revenue impact of timely, relevant automation.

Despite these compelling statistics, only 68% of businesses use email automation, and the average business operates just 5.2 automated flows. This represents a significant opportunity for businesses willing to invest in comprehensive automation strategies through their email marketing programme.

Personalisation Impact

Personalisation — tailoring email content to individual recipients based on their data, behaviour, and preferences — dramatically improves email performance across all metrics.

Personalisation Tactic Impact on Performance
Personalised subject lines +26% open rate
Personalised email body content +41% click-through rate
Dynamic product recommendations +35% revenue per email
Segmented campaigns (vs non-segmented) +50% CTR, +760% revenue
Behaviour-triggered personalisation +73% conversion rate
Location-based personalisation +29% open rate
Send-time personalisation +22% open rate
Consumers expecting personalised experiences 72%
Consumers frustrated by non-personalised content 63%

The statistics on personalisation are compelling. Segmented campaigns deliver 760% more revenue than non-segmented broadcasts. Dynamic product recommendations increase revenue per email by 35%. Behaviour-triggered personalisation boosts conversion rates by 73%.

Consumer expectations have shifted decisively toward personalisation: 72% of consumers expect brands to deliver personalised experiences, and 63% are frustrated by generic, one-size-fits-all content. In Singapore’s competitive market, where consumers have abundant choices, personalisation is no longer a differentiator but a baseline expectation.

The most impactful personalisation approaches combine multiple data points: purchase history, browsing behaviour, demographic information, and engagement patterns. This level of personalisation requires robust data infrastructure and marketing automation tools, but the ROI consistently justifies the investment.

Email Marketing ROI

Email marketing delivers the highest ROI of any digital marketing channel, making it one of the most cost-effective tools available to Singapore businesses.

ROI Statistic Value (2026)
Average email marketing ROI SGD 38 per SGD 1 spent
E-commerce email marketing ROI SGD 42 per SGD 1 spent
B2B email marketing ROI SGD 35 per SGD 1 spent
Email share of total digital marketing revenue 23%
Average cost per email sent SGD 0.008 – 0.025
Businesses rating email as their top ROI channel 41%
Email marketing budget as % of total marketing 8-12%

Email marketing delivers an average ROI of SGD 38 for every SGD 1 spent, far exceeding any other digital channel. E-commerce businesses achieve even higher returns at SGD 42 per SGD 1, driven by automated flows like abandoned cart recovery and post-purchase upselling.

Despite generating 23% of total digital marketing revenue, email marketing typically receives only 8-12% of the total marketing budget. This disconnect suggests that most businesses are under-investing in email relative to its revenue contribution. Increasing email investment, particularly in automation and personalisation, represents one of the highest-ROI moves a Singapore business can make.

The cost efficiency is remarkable: the average cost per email sent ranges from just SGD 0.008 to SGD 0.025, depending on the platform, list size, and features used. Compared to CPCs of SGD 1-8 on advertising platforms, email’s unit economics are dramatically favourable for businesses with established subscriber lists.

Unsubscribe and Deliverability Benchmarks

Maintaining list health through low unsubscribe rates and high deliverability is essential for long-term email marketing success.

Metric Benchmark (2026)
Average unsubscribe rate 0.18%
Acceptable unsubscribe rate Below 0.5%
Average spam complaint rate 0.02%
Maximum spam complaint rate (before deliverability impact) 0.1%
Average email deliverability rate 95.7%
Average bounce rate (hard bounces) 0.4%
Average bounce rate (soft bounces) 0.9%
List decay rate (annual) 22-25%
Businesses with DMARC authentication 62%

The average unsubscribe rate across all industries is 0.18%, with anything below 0.5% per campaign considered healthy. Unsubscribe rates above this threshold may indicate issues with email frequency, relevance, or list quality.

Spam complaint rates must be kept below 0.1% to avoid deliverability penalties from major inbox providers. The industry average of 0.02% shows that most businesses maintain acceptable levels, but a single poorly targeted or overly frequent campaign can spike this rate and damage sender reputation.

Email lists naturally decay at a rate of 22-25% annually as subscribers change email addresses, lose interest, or mark emails as spam. This means you need to continuously grow your list just to maintain its current size. List-building strategies through content marketing, lead magnets, and website opt-in forms are essential for offsetting this natural attrition.

Deliverability is a growing concern, with only 62% of businesses having fully implemented DMARC email authentication. Google and Yahoo’s stricter sender requirements, introduced in 2024 and expanded in 2025-2026, make proper authentication (SPF, DKIM, DMARC) mandatory for reliable inbox placement.

Frequently Asked Questions

What is a good email open rate in 2026?

The all-industry average open rate is 25.8%. A “good” open rate depends on your industry: education and non-profit see rates above 29%, while retail and technology average around 24%. Any open rate above your industry benchmark is performing well. Keep in mind that Apple Mail Privacy Protection inflates open rates, so use click-through rate as a more reliable engagement measure.

How often should I send marketing emails?

For B2C businesses, 2-4 emails per week is optimal. For B2B, 1-2 emails per week works best. Sending more than 5 emails per week significantly increases unsubscribe rates. The key is delivering consistent value with each email rather than simply increasing frequency. Test different frequencies with your specific audience and monitor unsubscribe rates as your guide.

What is the ROI of email marketing?

Email marketing delivers an average ROI of SGD 38 for every SGD 1 spent, the highest of any digital marketing channel. E-commerce businesses see even higher returns at SGD 42 per SGD 1. This ROI is driven by the low cost per email (SGD 0.008-0.025) and the high engagement rates of properly segmented, personalised campaigns.

Are automated emails really more effective than manual campaigns?

Yes, dramatically so. Automated emails achieve 70% higher open rates and 152% higher click-through rates than manual broadcasts. They generate 31% of total email revenue despite representing a smaller share of total volume. Welcome emails, abandoned cart reminders, and post-purchase follow-ups are the most impactful automated sequences to implement.

What is the best time to send emails in Singapore?

The primary optimal window is 10:00 AM to 11:00 AM SGT, when professionals are actively checking emails during the workday. A secondary peak occurs at 8:00 PM to 9:00 PM SGT for consumer audiences. Tuesday and Thursday are the best-performing days for B2C, while Tuesday and Wednesday work best for B2B. Saturday generally shows the weakest performance.
