+This addon extends the unsubscription form to let you:
+
+- Choose which mailing lists are not cross-unsubscriptable when unsubscribing
+  from a different one.
+- Know why and when a contact has been subscribed or unsubscribed from a
+  mass mailing.
+- Provide proof on why you are sending mass mailings to a given contact, as
+  required by the GDPR in Europe.
+
+**Table of contents**
+
+.. contents::
+   :local:
+
+Configuration
+=============
+
+You can customize what reasons will be displayed to your unsubscriptors when
+they are going to unsubscribe. To do it:
+
+#. Go to *Mass Mailing > Configuration > Unsubscription Reasons*.
+#. Create / edit / remove / sort as usual.
+#. If *Details required* is enabled, they will have to fill a text area to
+   continue.
+
+Usage
+=====
+
+Once configured:
+
+#. Go to *Mass Mailing > Mailings > Mass Mailings > Create*.
+#. Edit your mass mailing at wish, but remember to add a snippet from
+   *Footers*, so people have an *Unsubscribe* link.
+#. Send it.
+#. If somebody gets unsubscribed, you will see logs about that under
+   *Mass Mailing > Mailings > Unsubscriptions*.
+
+Known issues / Roadmap
+======================
+
+* As version 11 has introduced a new relation type between mailing lists and
+  contacts that has multiple usability issues that are being reworked by Odoo
+  to land in version 12, this module falls back to the version 10 behaviour in
+  which one contact belonged to just one list.
+* This module replaces AJAX submission core implementation from the mailing
+  list management form, because it is impossible to extend it. When
+  https://github.com/odoo/odoo/pull/14386 gets merged (which upstreams most
+  needed changes), this addon will need a refactoring (mostly removing
+  duplicated functionality and depending on it instead of replacing it). In the
+  mean time, there is a little chance that this introduces some
+  incompatibilities with other addons that depend on ``website_mass_mailing``.
+

+<p>This addon extends the unsubscription form to let you:</p>
+<ul class="simple">
+<li>Choose which mailing lists are not cross-unsubscriptable when unsubscribing
+from a different one.</li>
+<li>Know why and when a contact has been subscribed or unsubscribed from a
+mass mailing.</li>
+<li>Provide proof on why you are sending mass mailings to a given contact, as
+required by the GDPR in Europe.</li>
+</ul>

+<p>You can customize what reasons will be displayed to your unsubscriptors when
+they are going to unsubscribe. To do it:</p>
+<ol class="arabic simple">
+<li>Go to <em>Mass Mailing &gt; Configuration &gt; Unsubscription Reasons</em>.</li>
+<li>Create / edit / remove / sort as usual.</li>
+<li>If <em>Details required</em> is enabled, they will have to fill a text area to

+<p>Once configured:</p>
+<ol class="arabic simple">
+<li>Go to <em>Mass Mailing &gt; Mailings &gt; Mass Mailings &gt; Create</em>.</li>
+<li>Edit your mass mailing at wish, but remember to add a snippet from
+<em>Footers</em>, so people have an <em>Unsubscribe</em> link.</li>
+<li>Send it.</li>
+<li>If somebody gets unsubscribed, you will see logs about that under
+<em>Mass Mailing &gt; Mailings &gt; Unsubscriptions</em>.</li>

+<ul class="simple">
+<li>As version 11 has introduced a new relation type between mailing lists and
+contacts that has multiple usability issues that are being reworked by Odoo
+to land in version 12, this module falls back to the version 10 behaviour in
+which one contact belonged to just one list.</li>
+<li>This module replaces AJAX submission core implementation from the mailing
+list management form, because it is impossible to extend it. When
+<a class="reference external" href="https://github.com/odoo/odoo/pull/14386">https://github.com/odoo/odoo/pull/14386</a> gets merged (which upstreams most
+needed changes), this addon will need a refactoring (mostly removing
+duplicated functionality and depending on it instead of replacing it). In the
+mean time, there is a little chance that this introduces some
+incompatibilities with other addons that depend on <tt class="docutils literal">website_mass_mailing</tt>.</li>
