How do your email campaigns compare?

For the last 11 years we’ve been compiling annual reports to help you benchmark the performance of your email campaigns against your peers.

There are lots of reports out there focused on large brands and US companies, but we found a real lack of UK-specific data. These benchmarks are unique as they focus primarily on UK based small-medium sized businesses. Our email benchmarks are based on marketing emails sent by our clients – predominantly to UK based subscribers – and are broken down into 29 different industry sectors.

We’ve been compiling our annual Benchmark Reports for 11 years. Please get in contact if you’re interested in archive data from further back. We’ll be pleased to help if we can.


Let’s define some of the terms we’re using as several of these figures can be (and often are!) calculated in different ways. All figures we use are based on unique user actions – for example we only count the same recipient opening a campaign once, if they open that campaign again we don’t count that as another open.

Bounced: messages returned by the receiving mail server as undeliverable.

Delivered: messages accepted for delivery by the receiving mail server i.e. total sent – bounced.

Open Rate: the percentage of delivered emails that were opened (measured by an image load or link click); i.e. number opened / delivered.

Clicks: the percentage of delivered emails that had a link clicked; i.e. unique clicks / delivered.

Unsubscribes: the percentage of delivered emails that result in an unsubscription; i.e.unsubscribes / delivered For some of the reports we use different ratios, as these are a better way to compare some aspects of campaign performance – these are:

Click to Open: the percentage of opened emails that had a link clicked; i.e. unique clicks / opens.

Unsubscribe to Open: the percentage of opened emails that result in an unsubscription; i.e. unsubscribes / opens.

We use these ‘x to Open’ figures as ways to compare the performance of the actual campaign content because these look at what happens after the first objective of someone actually opening the campaign has been achieved.

If you are already a customer you can compare your campaign results with the averages for your industry directly in your account? Here’s how to set your industry sector and compare your results.
