When is the best time to send an email?

While it’s tempting to seek a one-size-fits all solution, there’s no single best time to send an email. Reviewing your email marketing analytics can help you understand what has worked for your customers, but the more useful question is when their behavior creates a relevant opportunity to connect.

A product view, an abandoned cart, or a return visit can signal interest in the moment. Being able to act on those signals in real time helps marketers deliver messages that reflect what customers are doing now. Let’s unpack some common email timing assumptions to discover what strategies may be hiding in plain sight.

Key takeaways

• There is no universal best time to send an email; customer behavior and message relevance should guide timing.
• Tuesday mornings, overnight sends, and weekends are opportunities to test rather than guaranteed performance windows.
• Recent customer actions can create timely opportunities that a fixed campaign schedule may miss.
• Responding in real time means evaluating current behavior and choosing an appropriate next step, not emailing after every action.
• Measure clicks and conversions alongside unsubscribe and complaint rates rather than relying on opens alone.

Email timing best practices: Is it black-and-white or a gray area?

Common sending windows can provide starting points for testing, but they don’t reveal when an individual customer is actively interested in your brand. Consider these recommendations in the context of your audience’s behavior.

Sending at 8am on Tuesday

This is a time that is often recommended because it falls in the middle of the week, right before working hours begin. But just because there is general guidance that this time will work well, doesn’t mean it’s the right fit for your audience. The only way to know if this is true for your brand is to test and see what works best.

Sometimes these peak time slots will mean you have increased competition with other brands that are pushing messages to customers around the same time, resulting in your message getting lost in the mix.

Sending an email in the middle of the night

Sending emails in the middle of the night does have some advantages. Your brand may not have to compete for inbox attention at those hours, and early risers often check emails when they wake up. That would mean your brand's emails would be very near the top of their inbox allowing for good visibility and the potential for high engagement. You may also catch customers who can't sleep or are on their phone at 2am.

The effectiveness of this time slot truly depends on your customer base, so as always, testing can help you determine if your emails get better engagement after midnight and before 8am.

Sending an email on the weekend 

This one may surprise you because many brands make the assumption that people are busy on the weekends and aren’t checking emails. However, the odds of someone spotting your newsletter or email in a crowded inbox during the week are significantly lower than sending it to a deserted inbox on a quiet Saturday.

A weekend day could be an amazing opportunity to stand out – as long as you don’t wind up annoying customers along the way.

How audience and industry influence email timing

Different industries will experience varying levels of engagement on weekends. For example, retail and leisure sectors may see higher open rates and repeat purchases due to customers planning their shopping or recreational activities. Your brand’s audience plays a big part in engagement, so treat these patterns as possibilities to test.

FAQs about the best time to send an email

How can marketers tell whether customer activity warrants an email?

Consider the strength and context of the signal. Repeated product views or an abandoned cart may suggest more interest than a single page visit. Check whether the proposed message would help the customer take a relevant next step, rather than treating every interaction as a reason to send.

What should happen if customer behavior changes after an email journey begins?

The next message should reflect the customer’s latest activity. A purchase may end an abandonment journey, while a change in product interest may call for different content. Review how your journeys update eligibility, message selection, and timing after customers enter.

Should time-sensitive emails wait for an optimized sending window?

Messages customers need immediately, such as password resets and purchase confirmations, should follow the action that triggered them. For promotional emails with a deadline, ensure any optimized sending window leaves recipients enough time to act.

How can overlapping campaigns affect email timing decisions?

A relevant message can still arrive at an inconvenient moment if the customer has already received several other emails. Review scheduled campaigns alongside automated journeys to understand total message frequency and determine whether the next email should be sent, delayed, or suppressed.
