Integrating constant contact with Paid Membership Pro for sending autoresponders

Hello,

We have a site in wordpress. The url of the site is :
https://www.margaretmarcuson.com/leaderswholast/

In this site, we are using Paid Membership Pro plugin for selling the content in the form of pdf files.

Paid Membership Plugin provides Constant Contact as an add on which helps in email marketing or setting some automated mails/newsletters.

In our site, we have a post/product in which client has some pdf links which she want to send to her clients on weekly basis which will be an automated process.

Suppose one product/post has 8-10 pdf files/links. Client want to send the very first pdf link on the same day
when the customer has done the payment for the product/post. The rest of the successive pdfs she want to send to the customers
on weekly basis. Every coming week client want to send the next/successive pdf.

Our requirement is we need an automated process in which the constant contact itself find out the product’s purchase date and send the successive
pdf files automatically on weekly basis.

Our query is whether do you have any built in functionality that can be integrated with Paid Membership Pro for the above requirement which your
“Constant Contact” addon can provide.

Let us know in case you need any detail information from us that can help you to better reply our query.

Regards
