With Matomo (Piwik) you can add a small image beacon (pixel) in your newsletter emails, so you can track how many people actually read and open the newsletter email.
To track how many people open and read your newsletters, you can add the following HTML image code in your newsletter:
<img src="https://piwik.example.com/piwik.php?idsite=YOUR_PIWIK_WEBSITE_ID&rec=1&bots=1&url=https%3A%2F%2Fexample.com%2Femail-opened%2Fnewsletter_XYZ&action_name=Email%20opened&_rcn=internal%20email%20name&_rck=newsletter_XYZ" style="border:0;” alt="" />
Once you add this code in your newsletters, when your users open and read the newsletter, it will add a new “Page title” entry for “Email opened” in your Actions> Page titles report.
You will also be able to see this information in the Visitor Log.
In this example, replace:
https://piwik.example.com/by your Matomo URL
YOUR_PIWIK_WEBSITE_IDby your Website ID (learn more)
When you use the HTML code above, the following information will also be recorded in Matomo:
&url=%2Femail-opened%2Fnewsletter_XYZrecords a pageview with the URL set to to “/email-opened/newsletter_XYZ” in Actions > Page URLs report.
&action_name=Email%20openedrecords a Page Title set to “Email opened” in Actions > Page titles report.
&_rcn=internal%20email%20namerecords a visit from a Campaign and sets the campaign name to “internal email name” in Referrers > Campaigns report.
&_rck=newsletter_XYZwill also set the campaign keyword to “newsletter_XYZ” (set it to the name of this particular email newsletter for example “Summer-deals-2017-August”) in Referrers > Campaigns report.
