Custom event not sending notification email I'm creating a plugin called "Membership" to handle user subscriptions through Stripe. I want to use SproutEmail to handle notification.

I've created a custom event as per the Sprout instructions:

&lt;?php
namespace Craft;

class SproutEmail_SubscribeEvent extends SproutEmailBaseEvent
{
    /**
     * Returns the qualified event name to use when registering with craft()-&gt;on
     *
     * @return string
     */
    public function getName()
    {
        return 'membership.onSubscribe';
    }

    /**
     * Returns the event title to use when displaying a label or similar use case
     *
     * @return string
     */
    public function getTitle()
    {
        return Craft::t('When a user subscribes to a membership plan.');
    }

    /**
     * Returns a short description of this event
     *
     * @return string
     */
    public function getDescription()
    {
        return Craft::t('Triggers after a user has subscribed.');
    }

    /**
     * Returns the data passed in by the triggered event
     *
     * @param Event $event
     *
     * @return mixed
     */
    public function prepareParams(Event $event)
    {
        return [
            'value' =&gt; $event-&gt;params['user']
        ];
    }
}


SproutEmail is picking this up and I can select it as a rule:



I added a listener to my plugin for membership.onSubscribe to ensure it's working properly:

craft()-&gt;on('membership.onSubscribe', function(Event $event) {
    MembershipPlugin::log('membership.onSubscribe was triggered.');
});


And it appears to be:

2017/02/16 15:07:33 [info] [plugin] membership.onSubscribe was triggered.
in /home/vagrant/Code/sbl.loc/craft/app/etc/plugins/BasePlugin.php (65)
in /home/vagrant/Code/sbl.loc/craft/plugins/membership/MembershipPlugin.php (56)
in /home/vagrant/Code/sbl.loc/craft/plugins/membership/services/MembershipService.php (15)

However SproutEmail doesn't sent out any notification email and when I check the logs for the plugin there is no mention that my custom event was triggered.

Does anyone have any idea what the issue might be?
We got to the bottom of this issue and it turned out to be that the SproutEmail_SubscribeEvent::validateOptions() method was returning false. Updating this to ensure the options were being validated properly fixed the issue:

public function validateOptions()
{
  return true;
}


We've updated the docs and will also more clearly document this in the SproutEmailBaseEvent class in the next release.
