Who really waits to get to their desk before reading their email these days? In reality, many people start their workday while walking into the café, or on the train. Or, if you’re like 50% of folks, you begin and end your day emailing in bed.
With habits like these, it’s no surprise then that 42% of first opens are made on mobile devices. But to find out more about how we open email today, we looked at data from over 192 million opens, then asked Gary Elphick – a mobile specialist at ideas agency Tongue – for his thoughts. Read on to find out whether the time of day you send is important and whether you can improve your results by rethinking when and what you send.
When do opens occur?
First of all, knowing when to send really means knowing your recipients and their behaviours. So, do you know what time of day do people read their emails, how much time they have to do so and how exactly they spend that time? Here’s when we observed people opening their email:
% Email Opens by Hour
Based on email campaigns sent worldwide, October 2013. Time zones were factored into the analysis and are set to that of the email sender.
To make more sense of the above, we decided to have a look at what time of day emails were opened, based on the typical workday of getting up, going to work, then going home:
9am – 5pm (minus lunchtime)53%
|Hours of the day||% Emails Opened|
|Midnight – 8am (before work)||16%|
|6pm – 11pm (after work)||24%|
As can be expected, the pattern of opens increases as people begin to wake up and start their day, then subside again dwindle as they go to sleep. But it’s worth highlighting:
- Workday hours (9am – 5pm) are when over half of all email opens happen
- Peak open times are just before and after lunch
- Lunchtime opens only drop by a fraction
- Including lunch, 47% of emails are opened outside of work hours. Note is that the majority of these “non-working” opens occur on mobile devices
Talking about devices, we also looked at which environments opens over time were happening:
% Email Opens by Device by Hour
From this, it’s clear that there’s a relationship between time of day and the platform you use to open your email. Based on hour of the day, email opens on mobile and desktop environments have an inverse relationship. Before work and after hours, emails are opened on mobile phones and desktop opens decline. During work hours, desktop opens increase and mobile opens decrease. This might seem fairly obvious, given that you’re likely to read your email on the train or bus commute to work (please don’t read emails while driving!), then switch to your desktop, or laptop when you get to your destination. However, it’s interesting to see the data back this up.
How do I optimize my email campaigns?
So, while it seems that we should be planning around the 9am “email rush”, the truth is that there is really no ideal time – after all, almost half of emails are opened outside of work hours. So, how about optimizing what we send, instead of when?
we need to be thinking in the same “time windows”For insight into this, we called on Gary Elphick. As email marketers, Gary suggests we need to be thinking in the same “time windows” as our subscribers; being the different periods interacting with emails, depending on the device. These windows are:
- The 3 minute window, when you’re most likely opening email on a mobile device. For example, when waiting for coffee at your local, you have just about enough time for a quick scan of new emails, to forward on any urgent tasks and to take note of anything that needs to be revisited later when you have more time.
- The 5 minute window, when you’re most likely opening email on a mobile device. Say, in a cab between meetings, you have time for a couple of quick email responses, to action urgent items and respond to important people.
- The 10 minute window, when you could be either mobile or desktop. For example, at lunch you have just enough time to respond to not-so-urgent emails, file things you’ve done and re-read those emails scanned earlier.
To ensure email marketers make the most of their email program spend, Gary offered 4 key considerations to keep in mind, prior to sending:
- Time of day – What is the best time of day to send your email marketing messages? Can you optimize for the time of day you are sending and the device most likely to open your email?
- Brevity – How much can someone really read during the 3 minutes they have in the coffee line? Keep your copy to the point and make call-to-actions as clear as possible
- First words – The first words of your campaign in your subject line are incredibly important content, so craft them with thought.
- Mobile first – With mobile email open rates at 42% and growing, we need to optimize our email marketing for a mobile first environment. Also, remember to test your landing pages on mobile; having someone tap through, only to end up on an unusable landing page is a terrible experience.
