Users will receive these reminder emails each time recurring period ends (so basically, 4 times a year as you said, total 12 emails)
If you just want to send one email before subscription end only, please don't configure the plan to send First, Second and Third reminder emails
Just set Send Subscription End setting to 5 days before subscription expired for example and the system will only send that one email (Subscription End Email) 5 days before the subscription ends/finishes)
One more question about the reminder emails at the end of a recurring subscription.
When I don't set a reminder email in the plan, which setting in the Configuration / Emails & Messages will be used?
Is that in Configuration / Emails & Messages / tab Reminder Messages and there the setting in "Recurring Subscription End Email"?
I was testing the subscriptionsplans with a duration of 4 days.
I set the Subscription End Message with subject and body, but I did not received that message by email.
I do receive the email about the new bought subscription.
As a user and as the admin. So the email works good.
But the reminder message which have to be send in my test one day before the subscription end is not send.
I have that issue for normal subscriptions and recurring subscriptions.
Have I missed a setting in the configuration for this?
