New Subscriptions for Existing Subscribers

[LIAPG]

I'm setting up subscriptions through paypal for a yearly membership.  Some people have previously paid their membership fee prior to setting up these subscriptions.  Is there anything I can do to get them "into the system" so that a reminder email is sent when their subscription should expire and they can pay through paypal?

Also, is there a way to preview/edit the subscription reminder email before it goes out?

You may want to look into PayPal's IPN feature.  Instant Payment Notification (IPN) is a message service that notifies you of events related to PayPal transactions. You can use this service to automate back-office and administrative functions, including fulfilling orders, tracking customers, and providing status and other information related to transactions.

With IPN, PayPal sends an IPN post when a subscription is created, a payment is made, and when it expires. You can use that IPN post to trigger a script to send your buyers a custom e-mail from your server. That e-mail can include a link to your site where the button is located or a link the buyers can click to be redirected to PayPal and resubscribe from there.  Once a subscription expires there's no way to get them back to sign up again.  Sending them an e-mail with an explanation that their subscription has expired can be useful both for you and your customer.
