In solidus_subscriptions, I’m unable to find any mailers or email templates. What is the best way to send email to customers on installments, cancellations, upcoming orders, etc?

The gem itself publishes a few built-in events on the lifecycle of the subscription. You can take a look at the calls to

create_and_emit_event

here (this is just one example) to get a feeling of what events you can subscribe to with the Solidus Event Bus.

thanks! I’m also using solidus_tracking, does that help?
