What’s the best time to send email?

Whenever there’s less competition.

According to Yesware’s analysis of over 500,000 sales emails, email open and reply rates are higher on the weekends. Why? It could be because there’s significantly less email being sent on weekends.

Think of it as the Late Night Infomercial Effect

Have you ever watched an infomercial at 3am?

It’s the time period known as the “Graveyard Slot” – when TV networks sign off and give up. But for certain companies (think Snuggie and ShamWow), the Graveyard is prime time and highly lucrative. That’s because when there’s nothing else on, night owls are more likely to watch an infomercial.

Similarly, the best time to send email is when there’s less competition. If there’s a lull in your contact’s inbox, your messages are more likely to stand out and get noticed. This in turn could lead to greater open and reply rates.

We see this same line of thinking when we look at email reply rates over 24 hours.

The best time to send email is the early morning or evening

The best time to send email

Emails sent in the early morning (between 6 and 7 am) and evening (around 8 pm) were the most effective at getting a response, with reply rates hovering around 45%. The graph above also reveals that much fewer emails were sent during these time slots.

Here are 9 more tactics to make people open and reply to your emails.

Last but not least: There is no “best day” to send email

If you’re saving Friday emails for Monday, you’re doing it wrong.

We ran the numbers and found that open and reply rates were pretty similar no matter what weekday an email was sent. Despite the bad rap, Fridays are no better or worse for sending emails than any other day of the work week.


The best time to send email is when send volume is the lowest – weekends, early mornings, and evenings. Remember that:

  • Email open and reply rates are highest on the weekends, when inbox competition is low.
  • People are most responsive in the early morning or later in the evening. If you’re having a hard time getting in touch with someone, try sending follow up emails between 6 and 7 AM, or around 8 PM.
  • All weekdays are equal. Instead of pitting Monday against Friday, focus on reaching out at effective times of day, crafting better subject lines, and harnessing the power of social proof to get more replies.
