Open and Click Tracking Have Arrived

We’re pleased to announce the addition of open and click tracking metrics to Amazon SES. These metrics will help you measure the effectiveness of the email campaigns you send using Amazon SES.

We’re also adding the ability to publish email sending metrics to Amazon Simple Notification Service (Amazon SNS) using event publishing. This feature gives you greater control over the sending notifications you receive through Amazon SNS.

What’s new in this release?

When you send an email using Amazon SES, we now collect metrics related to opens and clicks. Opens, in this sense, refers to the number of users who successfully received your email and opened it in their email clients; clicks refers to the number of users who received an email and clicked one or more links in it.

Additionally, you can now use event publishing to push email sending notifications—including open and click notifications—using Amazon SNS. Previously, you could send account-level notifications through Amazon SNS. These notifications were pretty limited: you could only receive notifications about bounces, complaints, and deliveries, and you would receive notifications about all of these events across your entire Amazon SES account. Now you can use event publishing to send notifications about deliveries, opens, clicks, bounces, and complaints. Furthermore, you can set up event publishing so that you only receive notifications about emails sent using the configuration sets you specify in those emails.

Why should I use open and click tracking?

Whether you are sending marketing emails, transactional emails, or notifications, you need to know how effective your communications are. The email sending metrics feature of Amazon SES gives you data about entire email response funnel—the total number of emails that were sent, bounced, viewed, and clicked. You can then transform those insights into action.

For example, the open and click tracking feature can help you identify the customers who are most interested in receiving the messages you send. By narrowing down your list of recipients and focusing on your most engaged customers, you can save money (by sending fewer messages), improve the response rates of your marketing campaigns (by targeting only the customers who are most interested in what you have to say), and protect your sender reputation (by reducing the number of bounces and complaints against your sending domain).

How do I enable open and click tracking?

If you’ve set up Sending Metrics in the past, then you can easily add open and click tracking to your existing configuration sets. On the Configuration Sets page, choose the configuration set that contains your sending event destination; edit the event destination, check the boxes for Open and Click (as shown in the image below), and then choose Save.

How does open and click tracking work?

Amazon SES makes very minor changes to your emails in order to make open and click tracking work. At the bottom of each message, we insert a 1 pixel by 1 pixel transparent GIF image. Each email includes a unique link to this image file; when the image is opened, we can tell exactly which message was opened and by whom.

To track clicks, we set up a redirect for each link in the message. When a recipient clicks a link, they are sent to an Amazon SES server, and are immediately forwarded to the destination address. As with open tracking, each of these redirect links is unique, allowing us to easily determine which recipient clicked the link, when they clicked it, and the email from which they arrived at the link.

Can I disable click tracking?

You can disable click tracking by adding a special tag to the anchor tags in your HTML. For example, if you were linking to the AWS home page, a normal anchor link would look something like this:

<a href="https://aws.amazon.com/">Amazon Web Services</a>

To disable click tracking for that same link, you would modify to look like this:

<a ses:no-track href="https://aws.amazon.com/">Amazon Web Services</a>

Because the ses:no-track attribute is non-standard HTML, we automatically remove it from the version of the email that arrives in your recipients’ inboxes.

How do I use event publishing with Amazon SNS?

If you’ve set up event destinations in the past, then the process of setting up an Amazon SNS event destination will be very familiar. You can add an Amazon SNS destination to an existing configuration set, or create a new configuration set that uses Amazon SNS as its event destination. To learn more, see “Set Up an Amazon SNS Event Destination for Amazon SES Event Publishing” in our Developer Guide.

We’re excited about this release. Let us know what you think of these new features in the SES Forum, or in the comments for this post.
