+Sometimes you don't have time to check the dashboard. Therefore you might miss a certain spike of traffic. That's why we created email reports. Do you want a monthly or weekly report of your website? Just enable it in [your account settings](https://simpleanalytics.com/account).
+
+> We are thinking of a feature where you can send these reports directly to your clients.
+
+The email will look more or less like this:
+
+<img class="border" style="width: 100%;" src="../../images/email-report.png" alt="">
+
+It includes the top 5 referrers and we compare them with the previous period. This gives you a indication of where your website is getting its traffic from, and how those numbers might have changed.
+
+In the example above it shows that we got significantly more traffic from our referral website _(referral.simpleanalytics.com <span style="color: #227522;">+963%</span>)_ than last week. Time for us to find out why. Thanks email report :)
+
+We send this email at 9AM in your local time zone. You can change this time zone per website in your website settings.
