Email Send Time: How to Optimize for Higher Conversions

Email send time is one of the most underrated yet powerful levers in an email marketing strategy. Even the most beautifully designed email marketing templates or compelling campaigns can underperform if sent at the wrong moment.

Choosing the best time of day to send marketing emails for conversions can mean the difference between being noticed or ignored. Let’s explore why timing matters, the factors that influence it, and how tools like cmercury, one of the best email marketing software platforms, can make send time optimization a predictable science instead of guesswork.

Why Send Time Matters in Email Marketing

At its heart, email marketing is the strategic art of reaching the right subscriber with the right content exactly when it matters most. Studies from email service providers like cmercury reveal that perfectly timed emails can:

• Increase open rates by over 20%
• Improve click-through rates
• Drive significantly higher conversions

When emails land in inboxes exactly when subscribers are most active, they’re more likely to engage, whether it’s for a flash sale, newsletter, or product update. This is one of the most important email marketing benefits for brands aiming for maximum ROI.

Factors That Influence the Best Send Time

1. Understand Your Audience Behavior

B2B email engagement peaks during weekday office hours, but B2C engagement often rises in the evenings and on weekends. For eCommerce conversions, knowing when your target audience shops online is crucial.

💡 Pro Tip: Use email marketing templates to quickly test different send times with minimal content edits.

2. Use A/B Testing for Send Times

A/B testing helps marketers evaluate two email versions and choose the one that generates better response rates. Majority of email marketing platforms come with built-in A/B testing tools, making campaign optimization effortless.

3. Leverage Industry Benchmarks (But verify)

While many email marketing companies publish benchmark studies, these should only be a starting point. Your data will always be more accurate for your audience.

4. Use Automation and AI for Precision

Modern email automation platforms, like cmercury, use AI to analyze historical engagement and predict the best send time for each subscriber. Email personalization plays a key role in boosting engagement levels and optimizing conversion performance.
