The Best Day of the Week for Email Marketing (Data-Backed Insights)

Email marketing remains one of the most effective digital marketing strategies, with an impressive ROI of $$36for\; every$1 spent (Campaign Monitor, 2023). However, sending emails at the right time is crucial for maximizing open rates, click-through rates (CTR), and conversions.

What the Data Says

Multiple studies have analyzed the best days to send marketing emails. Here’s what the research shows:

1. Mid-Week (Tuesday, Wednesday, Thursday) Performs Best

• Tuesday is often ranked as the top day for email opens and engagement (HubSpot, Mailchimp).
• Wednesday follows closely, offering strong CTRs.
• Thursday is another solid choice, especially for B2B audiences.

Why?

• People are back in work mode after Monday.
• Weekends are too far away for distractions.
• Decision-makers are actively checking emails mid-week.

2. Monday & Friday Are Riskier

• Monday: Inboxes are flooded after the weekend, leading to lower open rates.
• Friday: People are winding down for the weekend, making them less likely to engage.

3. Weekends (Saturday & Sunday) Can Work for Certain Industries

• E-commerce and B2C brands sometimes see success on weekends.
• Subscribers may have more leisure time to browse deals.

Industry-Specific Best Days

• B2B: Tuesday–Thursday (Best for decision-makers)
• E-commerce: Thursday–Sunday (Weekend shoppers)
• SaaS & Tech: Wednesday (Mid-week productivity peak)
• Nonprofits: Mid-week, especially Wednesday (Higher donation intent)

Best Time to Send Emails

Along with the right day, timing matters:

• Best times: 10 AM–12 PM & 1 PM–3 PM (When people check emails between meetings).
• Avoid early mornings (before 8 AM) and late nights (after 8 PM).

Key Takeaways
