> "How are my emails doing?"
>
> "Is anyone engaging with my CTA?"
>
> "How many users saw my announcement?"

These are the questions that come when you start sending emails at scale.

Today, Resend helps you not just answer, but take action on those questions.

## More than curiosity

We believe open and click tracking offers practical and actionable insights to better engage with your users.

Ultimately, opens and clicks show you which customers are the most interested in receiving the messages you send.

By knowing this you can:

- Measure results of your emails
- Have a better understanding of your audience
- Transform these insights into action by refining your email templates

## How open tracking works

When open tracking is enabled, we insert a 1 pixel by 1 pixel transparent GIF image at the bottom of each message.

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 which user.

<blockquote>
  "If you're a developer or working on a startup, you're going to love Resend's
  approach to emailing."

    <div class="quote-avatars">
      <div class="quote-avatar">

          height="40"
        />
      </div>
      <div class="quote-avatar quote-avatar-author">

          src="/static/avatars/joe-demaria.jpg"
          width="40"
          height="40"
        />
      </div>
    </div>
    <span class="quote-author">
      <span class="quote-author-name">Joe DeMaria</span>
      <span class="quote-author-job">Co-founder & CEO of SpecCheck</span>
    </span>
  </div>
</blockquote>

## How click tracking works

When click tracking is enabled, we set up a redirect for each link in the message. When your user clicks a link, they are routed to a Resend server and then immediately forwarded to the address you provided. This handoff is imperceivable to the recipient in normal circumstances.

As with open tracking, each of these redirect links is unique, allowing you to easily determine which person clicked which link at what time.

  "We were up and running with Resend in no time. It was seamless to integrate
  into our existing workflow and gave us a tremendous amount of visibility into
  our email capabilities. Simple to say, it was a no-brainer."

## Perfectly paired with Webhooks

[We announced Webhooks](https://resend.com/blog/webhooks) earlier this week, perfect timing for open and click tracking.

Creating a webhook stream of your tracking events gives you a live pulse of your contact list so you can take action immediately.

You can also feed these data points into an external storage system to provide more context alongside your other user events.

## How to enable tracking

Tracking is configured on the domain level.

You can enable tracking today by navigating to Domains, selecting the domain you want to enable and looking for the "Configuration" section.
