Best Time to Send Email on Sunday: Maximize Open Rates and Engagement

Email marketing is one of the most effective ways to engage your audience, but timing plays a crucial role in determining whether your email gets opened or ignored. While Sundays may seem like an unconventional day for email marketing, they offer unique opportunities to capture your audience’s attention when inbox competition is lower. However, understanding audience behavior and the best time to send emails on Sunday can significantly impact open rates, click-throughs, and conversions.

In this article, we’ll explore a Best Time to Send Email on Sunday, along with data-backed strategies and insights on optimizing your email.

Why Timing Matters

The time you send an email affects not only the open rate but also the engagement level and conversion potential. Here’s why:

1. Impact on Open Rates, Click-Throughs, and Conversions

• People tend to open emails when they are in a relaxed state and have time to read through them.
• If an email arrives at the wrong time, it may get buried under new messages by the time the user checks their inbox.
• Sending emails at the right time ensures your message is seen, read, and acted upon.

2. Weekend Inbox Competition is Lower—But Attention Span May Be Too

• Unlike weekdays when inboxes are flooded with work-related emails, Sundays usually have lower email traffic.
• This means your email has a higher chance of standing out, but since it’s a day of leisure, recipients may be less inclined to take action immediately.

3. Behavior Patterns: Users Often Check Emails During Quiet Morning Hours or Late Evening

• Many people check emails as part of their morning routine while having coee or before starting their day.
• Others check emails in the evening as they prepare for the upcoming week.
• Understanding these behaviors can help determine the optimal Sunday email send time.

Factors That Impact the Timing of Sunday Emails

Choosing the best time for your Sunday email depends on several factors:

1. Audience Behavior (B2B vs. B2C)

• B2B (Business-to-Business): Professionals may check emails on Sunday evenings while planning their week.
• B2C (Business-to-Consumer): Consumers are more likely to engage with promotional emails in the morning when they have downtime.

2. Type of Email (Promotional, Transactional, Newsletter)

• Promotional emails: Best sent when the recipient has time to browse offers (morning or evening).
• Transactional emails: These should be sent immediately upon a trigger action (e.g., order confirmation).
• Newsletters: Work well in the morning when recipients are more likely to engage with longer content.

3. Past Campaign Performance

• Reviewing past email analytics can help identify patterns in open rates and engagement on Sundays.
• A/B testing can refine timing strategies for optimal results.

4. Industry Trends and Benchmarks

• Different industries have different peak engagement times.
• For example, e-commerce brands may see higher engagement on Sunday evenings, while lifestyle blogs may perform better in the morning.

5. Mobile vs. Desktop Open Behavior on Weekends

• Mobile email open rates tend to be higher on Sundays since people check emails casually from their phones.
• Desktop engagement is lower as fewer people are at work.

What Time Zone Your Customers Are In

1. Importance of Segmenting Email Lists by Region or Time Zone

• A global audience means recipients are in different time zones.
• Scheduling emails according to their local time ensures maximum engagement.

2. Use of Tools That Auto-Adjust Send Time

• Email marketing tools like Mailchimp, Klaviyo, and HubSpot allow automated scheduling based on the recipient’s time zone.

3. Tips for Global Campaigns

• If targeting an international audience, stagger email send times based on local peak hours.
• A/B test different time zones to see which ones yield the best results.

Based on research and industry insights, here are the recommended times to send Sunday emails:

2. Evening (5 PM – 8 PM): Prep for the Coming Week

• Sunday evenings see a spike in email opens as people wind down and plan for the week ahead.
