How to Improve Your Email Performance?

Many of our customers ask us, “What’s the best time to send out emails?” Before we dive into numbers, let’s first get technical:

There is a lot that should go into play before sending your emails:


- The quality of prospects is and should be #1. We target our audience by as many segments as possible. The industry your customers are in can be a major consideration, for example. Healthcare professionals/ doctors have different hours than a school teacher or restaurant owner.

- The subject line should stand out.

- Make sure you are sending emails in accordance with the time zone the recipients are in.

- Personalize your emails when possible.

Let’s now dive into the numbers and figure out when is the best time to send emails. In the following study, they took the results from 998,384 emails that were successfully delivered over 12 months, sent out between 8 am to 5 pm. Here are the numbers:

The first impression is that any hour of the day would be a good time to send emails, but we would be wrong to look only at the opening rate. We want our customers to respond to our emails, and so what we should really look at are the response rate numbers:

Email Responsive Rate

This data shows that sending emails early in the morning will get you the best results. From 08:00 to 11:00, the response rate was 75.77%.

You can conduct your own research by looking at the data of emails you sent out. This can show you what times work best for your customers. Check the open rate and response rate reports to discover patterns. Another popular way to find the best time is to conduct an A/B test, by sending an email to different groups at different times and comparing the results.
