In the fast-paced world of digital marketing, timing isn’t just important—it’s everything. You can craft the most compelling email copy, offer unbeatable discounts, and have a sleek, mobile-optimized design. But if your email lands in your audience’s inbox at the wrong time, it risks being ignored, archived, or worse—deleted. Understanding when to send your marketing emails is a game-changer for improving open rates, click-throughs, and conversions.
This comprehensive guide explores the best days and times to send marketing emails, backed by data from leading industry reports, tools like Mailchimp and HubSpot, and behavioral trends in 2025. We’ll also break down timing strategies by industry, audience type, and email intent so you can tailor your approach for maximum effectiveness.
Why Timing Matters in Email Marketing
Marketing emails live in a highly competitive space: the average person receives over 100 emails per day. To cut through the noise, the when becomes just as important as the what. Here’s how timing impacts your email campaign performance:
-
Open Rates: Recipients are more likely to open emails when they aren’t overwhelmed with messages.
-
Click-Through Rates (CTR): Engagement is higher when emails are sent during peak productivity or browsing windows.
-
Conversions: The right timing aligns with user behavior—whether shopping, planning, or exploring services.
If you send your email at the wrong time, you risk it being buried under more urgent or recent emails, making your message invisible no matter how relevant or personalized it is.
General Data-Backed Findings on the Best Days to Send Emails
Multiple studies from tools like Campaign Monitor, Mailchimp, GetResponse, and HubSpot have highlighted consistent patterns in email engagement over the years.
🔹 Best Days (General B2B and B2C Data):
| Rank | Day | Why It Works |
|---|---|---|
| 1 | Tuesday | Highest open rates and CTR. People are settled into the week and checking emails more carefully. |
| 2 | Thursday | Performs nearly as well as Tuesday, especially for B2B. Good for follow-ups and promotional offers. |
| 3 | Wednesday | A solid mid-week performer, especially effective for newsletters or educational content. |
🚫 Worst Days to Send:
-
Monday: Overloaded inboxes from the weekend can drown out your message.
-
Friday: People mentally check out and prepare for the weekend.
-
Saturday & Sunday: Low open and engagement rates—unless targeting weekend shoppers or hospitality sectors.
Best Times of Day to Send Marketing Emails
Your audience’s daily routine is just as important as the day itself. Here’s when your email is most likely to get noticed:
🔸 Optimal Send Times:
| Time Slot | Why It Works |
|---|---|
| 6 AM – 9 AM | Early risers check their inbox before starting the day. High open rates. |
| 10 AM – 11 AM | Mid-morning peak—recipients are active and alert, perfect for B2B messages. |
| 1 PM – 2 PM | Post-lunch browsing period; people catch up on messages before diving into afternoon work. |
| 4 PM – 6 PM | Slight spike in engagement as people wrap up their day or plan their evenings. |
| 8 PM – 10 PM | Night owls and mobile users check email before bed, ideal for B2C offers. |
🕒 Times to Avoid:
-
12 PM – 1 PM: People are usually at lunch or away from their desk.
-
3 PM – 4 PM: Afternoon slump = lower attention span.
-
After 10 PM: Email fatigue kicks in. Messages are likely to be ignored or deleted.
