What’s A Good Email Open Rate?

What's a good open rate

Let’s demystify what “good” stats mean. All too often people expect unrealistic open and click rates and are disappointed when they only achieve one third of that.

How our delivery, open and click rates are calculated

Our rates are calculated on a per subscriber basis, rather than total values. This is called unique and it means that if one subscriber opens the email 5 times, then it only counts once, so you could never have more than 100%. This is a much more accurate way of calculating how many people have enjoyed your newsletter.

Delivery rate % = (Emails Delivered ÷ Emails Sent) x 100

Open rate % = (Opens ÷ Emails Delivered) x 100

Click rate % = (Clicks ÷ Opens) x 100

How do we record email stats?

Delivered emails are all emails where we don’t receive a notification from the end email server that says the email couldn’t be delivered to the recipient. There’s no other way to do it. This doesn’t mean that all delivered emails are delivered; some email services have spam filters that remove the emails (before they even get as far as the recipient’s inbox) but don’t report back to tell us so.

The way that opens are recorded is by embedding a tiny invisible image in your email. When the image is downloaded with the email, the open is recorded. Some email clients don’t have images displayed by default, so if the recipient chooses not to turn images on, then the open won’t be recorded. This is also likely to happen if your email goes into the spam folder and is opened there, since images for spam emails are normally blocked in all email clients.

Additionally, if the recipient reads the plaintext version of the email (which we automatically generate for you) then the open won’t be recorded either, since plaintext is just text, not HTML, so there will be no formatting, no images, and so on.

Clicks are recorded by replacing the links in your email with special links, which when clicked, records that you’ve clicked on it. Then, they seamlessly direct you to the original link. You won’t even notice!

Why aren’t more people opening my emails?

There are a number of reasons why people either aren’t opening your emails or that opens aren’t being recorded properly.

Be honest: do you read every single email you receive? Probably not. If I leave my inbox for a day, I’ll be flooded with offers, “things I might like” recommendations based on my online activity and order confirmation emails. I don’t have the time or the inclination to read them all, so I select all and mark as read.

Another thing to consider is that your emails might not be delivered to the inbox. There is no way of telling to which email the folder went (apart from one very expensive service but even that isn’t 100% accurate), so if it didn’t go to the inbox, there’s a much lower chance of the recipient opening it.

When people get so many emails, you need to make sure that yours stand out, with a catchy subject line and relevant content people will want to read (so they’ll want to open based on previous experience). It might also make a difference when you send your emails, too.

What’s a good open rate then?

There are a lot of factors which contribute to open rate, as I’ve mentioned above. But, above all, the biggest one is list size.

For instance, if I have a list size of only 2, then if just one person opens that email, I’ve already got an open rate of 50%. Give me a list of 50,000 recipients and getting 25,000 people to open that email seems pretty unrealistic. Getting one extra person to perform an action on a small list will make a huge difference to the results making them more statistically sensitive.

Although we refuse to be nailed down to specific percentages, we would say that if you’re getting less than 15% opens, something is wrong. This could be that you’re using an old contact list or bought list (in which case you’re probably getting lower than expected delivery rates as well), your email server is set up wrong or is blacklisted, or that your subscribers are marking your messages as spam if they didn’t give you permission to email them.

Conversely, if you’re consistently achieving 100% opens, there might be something affecting the results too.

If you use MailPoet and you are having any the problems described above, please get in touch with our support team.

Just to reassure you, we’re sharing our Top Newsletters (available in the stats page of our Premium plugin) so you can see how our top 5 email newsletters have performed (ranked by open rate). When we sent 80 people an email about MailPoet stats, we had over 50% opens, compared to our normal fortnightly newsletter which tops out at about 30% on a good week.

It takes time to learn…

You cannot base failure or success of a newsletter on just one isolated result. Once you’ve sent a few emails, it’ll become much clearer what kind of results you can realistically achieve. Sending regularly and over a long period of time will give you the ability to compare all the newsletters you send, reviewing every factor that might have gone into attaining a certain result.

Working out how you can repeat the successes and learn from the failures is part of sending newsletters!
