Unique Open Rates Click to Tweet me

This chart displays the total number of unique emails opened for the first time (as opposed to being opened multiple times by the same recipient) as a percentage of the total number of emails sent.

The average email open rate is 21.96%

A contact is deemed to have opened an email when either: images within the email are viewed or downloaded (even within the preview pane of the email client, eg Outlook); or when a link within the email is clicked on.

Findings Unique Open Rates for Jan - Jul 2012 were slightly higher than the second half of 2011.

Tips Use a “from name” that your recipients will know and trust such as your company name. Write a compelling subject line that entices recipients to open your email. Your subject line should be intriguing – you could ask a question or state a benefit.

GET YOUR EMAIL OPENED

Unique Open Rates by Send Volumes Click to Tweet me

To remove any bias associated with large sends we have broken the Send Volumes into five categories based on the number of contacts: 5,000 - 9,999 5 - 499 10,000+ 500 - 999 1,000 - 4,999

Send relevant email content to smaller database segments for best results

Findings Unique open rates have improved across the board, with only slight variations. Email sends to smaller recipient lists continue to out perform those sent to larger lists.

Tips If you have a large list try sending targeted emails to smaller segments so that readers receive highly relevant email content.

Findings Unique CTR’s across all industries, domains and send volumes were higher than the second half of 2011 by 0.02%. This figure only takes into account the first time an individual clicks on a link.

Tips The best way to increase your CTR is to make sure that your content is highly relevant and interesting. Include a strong call to action within the top 300 pixels of your email. Be clear on what action you want people to take from your email. A simple call to action with a text or image link can increase CTR’s.

Unique Click Through Rates by Send Volumes Click to Tweet me

This chart displays unique link clicks as a percentage of the total number of emails sent, whereby send volumes are broken into five categories based on the number of contacts: 5 - 499 5,000 - 9,999 500 - 999 10,000+ 1,000 - 4,999

Your email is almost twice as likely to get opened if it’s sent to a smaller database

Findings Unique CTR’s across all database sizes are approximately the same as 2011 with only sight increases and decreases.

Tips Jul - Dec 2011 5 - 499: 500 - 999: 1,000-4,999: 5,000-9,999: 10,000+:

The first step to improving click rates is to provide valuable content which readers want to learn more about. You can create links to pages on your website, web forms, social media pages, shopping carts or videos. Using links to landing pages is also an effective way to shorten your email as it moves a lot of content out of the body of your message. To ensure that your content, information and offers are relevant to your audience use conditional content to control what subscribers see based on their profile. For example, only show a drink special to people over 18.

Click Through Rate Relative to Open Rate This chart displays average unique CTR as a percentage of the total number of unique opened emails. This indicates how responsive the recipients who have opened an email are, giving a direct measure of the effectiveness of the email’s links and calls to action.

Findings CTR Relative to Open Rate has shown a decrease of 0.06% from the the second half of 2011 to the first half of 2012.

Tips Use your click through rates to gauge what your audience is most interested in. This information can be used to improve subject lines and consequently your open rates.

Jul - Dec 2011:

19.35%

Jan - Jun 2012:

19.29%

For example if the majority of your recipients click on competitions and not articles maybe your subject line should change from “10 ways to avoid hipsters” to “WIN great prizes & learn how to avoid hipsters.”

12

Bounce Rates This chart displays the total number of bounced emails as a percentage of the total number of emails sent. Bounce rates are often used as a key measure of deliverability and include permanent and temporary bounces. Permanent Bounces (AKA hard bounce) usually means the email address is incorrect or is no longer in operation. Temporary Bounces (AKA soft bounce) usually means the email address is temporarily unavailable, often because ‘server time expired’ or ‘mailbox full.’

Findings There has been a consistent trend of bounce rates gradually decreasing since the beginning of these reports in 2006 when the average bounce rate was 12.29%. In this half the bounce rates have continued to decrease and currently sit at 5.24%.

Jul - Dec 2011:

5.45%

Jan - Jun 2012:

5.24%

Tips Permanent bounces should be updated with a new email address or removed from your list. If your bounce rate is regularly 6% or higher it’s time for a data cleanse. You may be able to contact them using another method (such as phone or point of sale) to update contact details.
