Need Help With Newsletter Subscription on a WordPress Website

Hello,

I have a WooCommerce website where my previous developer had created a newsletter subscription box using optinmonster which was connected with constant contact.

As soon as someone subscribe for our newsletter they automatically receive a 20% discount code at their registered email. For the past couple of weeks this is not working correctly. Customers are not receiving email which contain discount coupon.

I am looking for a proficient wordpress developer who can look into this and fix the issue. You also need to check if optinmonster and constant contact are connected.

I have several small jobs like this for the right candidate
