Do you struggle with knowing when you should be sending out emails to your database of customers? The perfect time to send an email to your customers is not an exact science. However, there are a handful of findings that suggest you should be emailing at specific times during the day. The team at Hubspot has done in-depth research on the subject and we will be sharing their findings below. Continue reading for all your email marketing answers. 

The Significance of Email For Your Business  

Email marketing gives your business an advantage to increase sales conversions, perhaps as much as 14%. Sending out emails to your customers is a fantastic way to give them special offers and business updates that they can’t get anywhere else. You should be personalizing your emails to what you think your customers will be excited about reading. Once you know what you want to send, the next question is when to send your email. You will want to send it at the best time to ensure the highest opening rate possible. 

When You Should Send Your Email

GetResponse, an email marketing software company, went through a bunch of its data to create a report of email marketing benchmarks. They examined 4 billion emails from 1,000 active senders and came up with the following results. 


Overall, the highest click-to-open rates are 10 am, at 21%, 1 pm, at 22.5%, and another spike at about 6 pm. These numbers reflect when the majority of people start or end their day and therefore have more time to check their emails. 

The line that is highest on the graph shows the open rate. The purple line shows the click-to-open rate. At the very bottom, the blue line represents the click-through rate. The transparent wave is the count of the number of messages sent shown as a percentage. 

Knowing your buyer persona is key to knowing when to be sending emails to your audience. If they are a business professional with a typical nine-to-five job, think of sending your email out before their workday between 8-9:30 am. If sending out an email with a sale included, experiment sending it during their lunch break. 

Knowing daily routines is not the only factor that goes into email marketing. Other metrics such as click-through rate (CTR), click-to-open rate (CTOR), and open rate (OR) are beneficial when constructing emails. 

Click-through rate

The click-through rate indicates the number of people who open a link or a link attached to an image within an email. The CTR will always be a smaller number than the number of emails opened. Many people will open your email but click out of it before engaging. 

Click-to-open rate

The click-to-open data is established by comparing the number of people that opened your email with the number that clicked on any links. The CTOR assists you in finding out which information in your emails is interesting to your audience. The CTOR is determined by dividing CTR by the open rate and multiplying it by 100%. 

Open rate

The open rate is simply the percentage of subscribers who open your email. Typically, emails with short, compelling subject lines have great open rates. The open rate is directly related to the best day to send an email. CampaignMonitor found the following information by collecting data from millions of emails.


According to the data, it is clear that the best days for seeing a good open rate is during the workweek. People are generally opening and reading the most emails in the middle of the week. A good statistic to remember is that the lowest unsubscribe rate is at the start of the week. 

Email marketing can be a tricky business but is definitely worth using. Those who have subscribed to your email list are already interested in your business. They want to see more from you and what you can offer them. Keep your emails interesting and related to helping them and you will have a better chance at success with email marketing.
