Sendy is an email newsletter app that allows you to send trackable emails through Amazon’s Simple Email Service (SES).
This addon automatically subscribes customers to specific lists based on what they purchased. It also allows them to sign up for a list during the checkout process. This gives you the ability to send authenticated bulk emails, at an incredibly low price and without sacrificing deliverability.
Sendy is an addon for EDD, therefore you must have it installed on your website.
