Newsletters: Action Reference
The WordPress Newsletter plugin will fire actions throughout it’s code and you can hook onto these actions while receiving parameters and execute your own functions accordingly.
It works exactly like the WordPress Plugin API/Action Reference by using the
do_action()function in it’s code and the action hooks are used in the same manner.
More and more action hooks are constantly added to this documentation so remember to search or request more action hooks if you are looking for something specific. Below are all the available action hooks.
wpml_subscriber_saved– Runs when a subscriber is saved (created or updated). Arguments: $subscriber_id, $data.
wpml_field_saved– Runs after a custom field has been saved. Arguments: $field_id, $data
