Send email after a customer change address in address book

Question

I need to send an email after a customer try to save a new address in his address book

Answer 1

You can use below events for customer address.

<event name="customer_address_save_after">
    <observer name="customer_addres_after_save_event_observer" instance="Vendor\Extension\Observer\AfterAddressSaveObserver" />
</event>

OR

<event name="customer_address_save_before">
    <observer name="customer_address_before_save_event_observer" instance="Vendor\Extension\Observer\BeforeAddressSaveObserver" />
</event>

Answer 2

You should create etc/frontend/events.xml file in your module and post there event from Dhiren Vasoya comment. Then create the class Vendor\Extension\Observer\BeforeAddressSaveObserver OR Vendor\Extension\Observer\BeforeAddressSaveObserver depending on your event name and send email inside the class. You can google a little and find the way how to send email with custom template and parameters.
