+
+In order to properly understand the success or failure of an email marketing campaign, it is
+necessary to monitor several key metrics. The insights gained from these metrics can then be used to
+optimize future campaigns. Odoo's *Email Marketing* application tracks several :ref:`key metrics
+<email-marketing/key-metrics>`, that can be interpreted to improve future campaigns.
+
+View metrics
+============
+
+After a mass mail has been sent, the results for that particular mailing are displayed in multiple
+locations.
+
+To access the metrics for an individual mailing, navigate to :menuselection:`Email Marketing app
+--> Mailings`. Locate the specific mailing in the list view, and use the column headings to view the
+results for that mailing. Click on one of the mailings in the list to open the record. At the top of
+the record, detailed metrics are displayed as smart buttons.

+
+.. _email-marketing/key-metrics:
+
+Opened rate
+-----------
+
+The *Opened* rate measures the percentage of emails opened by recipients against the total number of
+sent emails.
+
+A high open rate may indicate that the subject line was timely, compelling, and successfully
+prompted the recipients to view the message.
+
+A low open rate may indicate the subject line failed to capture the recipients' interest. It could
+also indicate the email ended up in a spam or junk folder due to having a poor sender reputation or
+failing to :doc:`configure the proper DNS records <../../general/email_communication/email_domain>`.
+
+Replied rate
+------------
+
+The *Replied* rate measures the percentage of recipients who responded to the email directly against
+the total number of sent emails.
+
+A high replied rate may indicate the email resonated with recipients, prompting them to take action
+or provide feedback.
+
+A low replied rate may suggest that the message lacked relevance or did not contain a clear call to
+action.
+
+Clicked rate
+------------
+
+The *Clicked* through rate (CTR), measures the percentage of recipients who clicked on a link within
+the email against the total number of sent emails.
+
+A high |CTR| may indicate the email content was relevant and appropriately targeted. Recipients were
+motivated to click the links provided, and likely found the content engaging.
+
+A low |CTR| may indicate issues with either the targeting, or the content itself. Recipients may
+have been unmotivated by the calls to action, if there were any, or the message itself may have been
+directed toward the wrong audience.
+
+Received rate
+-------------
+
+The *Received* rate measures the percentage of emails that were successfully delivered against the
+total number of sent emails.
+
+A high received rate can indicate that the mailing list used is up to date and the sender
+authentication is trusted by email providers.
+
+A low received rate may indicate issues either with the mailing list used for the mailing or with
+the sender authentication. View the :ref:`email-marketing/deliverability-issues` section for more
+information.
+
+Bounced rate
+------------
+
+The *Bounced* rate measures the percentage of emails that were unsuccessfully delivered, against the
+total number of sent emails.
+
+A high bounce rate could indicate issues either with the mailing list used for the mailing or with
+the sender authentication.
+
+A low bounce rate may indicate that the mailing list used is up to date and the sender
+authentication is trusted by email providers. View the :ref:`email-marketing/deliverability-issues`
+section for more information.
+
+.. _email-marketing/deliverability-issues:
+
+Deliverability issues
+=====================
+
+The following define possible reasons for a high bounce rate or low received rate:
+
+- Using a mailing list that contains outdated contact information, or malformed email addresses are
+  likely to result in a high bounce rate and/or a low received rate.
+- Mailings sent using a *From* email address that differs from the sender's domain are likely to
+  bounce with certain email providers due to failing :ref:`DMARC authentication
+  <email_communication/DMARC_compliant>`.
+- Failing to :doc:`configure the proper DNS records
+  <../../general/email_communication/email_domain>` can also result in a high bounce rate.
