+Work with Mailing Lists
+=======================
+Mailing lists could be a goldmine for your company’s marketing department as they can provide leads
+for sales, focus groups for testing new products, and consumers to provide feedback on satisfaction,
+for example.
+
+Create Mailing lists
+=====================
+Go to :menuselection:`Mailing lists --> Mailing lists --> Create`. Enable the option *Is Public* to
+make the list visible for users when unsubscribing.

+
+Once your mailing list is created, you can manually add contacts clicking on *Create*. *Import* a
+list of contacts if you have it from a previous tool.
+
+
+Linking a mailing list to my website
+-------------------------------------
+| Create a mailing list called Newsletter, as you use this strategy to advertise and communicate new
+  ideas to subscribers interested in listening.
+| Go to your *Website*, add a *Newsletter* block and choose the respective mailing list.

+====================================
+Manage Unsubscriptions and Blacklist
+====================================
+It is best practice, and legally required, to allow recipients to unsubscribe from mailing lists
+as you do not want your audience to think that your company is using any tactics that are dishonest
+or spammy.
+
+Enable the Blacklist feature
+============================
+Go to :menuselection:`Configuration --> Settings` and enable the option *Blacklist Option when
+unsubscribing*.
+
+
+.. image:: media/manage1.png
+   :align: center
+   :alt: Blacklist in Odoo Email Marketing
+
+
+Now, once the user clicks on the *Unsubscribe* link on your email, he will be redirected to the
+following page:

+
+
+In addition to having the option of unsubscribing from specific mailing lists, the user can also
+blacklist himself, meaning that he will not receive *any* more emails from you.
+
+
+.. note::
+   The mailing list has to be configured as *Public* in order to be visible for users.
+
+
+| Under :menuselection:`Configuration --> Blacklist`, blacklisted email addresses will be shown.
+| When opening the record, as a *Log note*, a description-history is kept.

+  just certain contacts, filtering your target.

+   Platform the limit is 200. There is a possibility to increase these numbers by contacting Odoo
+   Support. To contact Support, `click here <https://www.odoo.com/help>`_.
+

+  be you. To do so, change the email address used as the sender (*Send From*).
+
+| With the *Reply To* radio button, you can also choose to gather answers either on the respective
+  recipients’ records or on a specific email address. Note that this option is not available if you

+| *Save*: the work will be allocated in the *draft* column in the kanban view. Modifications can be
+  made while being in this stage. The option *Discard* will delete the email.
+
+| Click on *Test* and send your message to one, or even multiple, test contacts to avoid errors.
+
+| *Send* will trigger the email with the next run and put the work on the *queue* column in the
+  kanban view.

+  the kanban view.

+   clicking on *Retry*.

+| The campaign option is effective as it allows you to organize your marketing efforts and have a
+  centralized view of its metrics.
