Subscriber Discounts for Easy Digital Downloads

MailChimp Key: This is a random string of letters and numbers that you need to enter in order to create a webhook in MailChimp. You can type anything you want here - it doesn't have to make sense. Something like e6uyUjSzNt9XTU51M1r5 is perfect. If this field is not filled in, your MailChimp subscribers won't receive a discount code. If you are not using MailChimp, leave this blank.
ActiveCampaign Key: This is a random string of letters and numbers that you need to enter in order to create a webhook in ActiveCampaign. You can type anything you want here - it doesn't have to make sense. Something like e6uyUjSzNt9XTU51M1r5 is perfect. If this field is not filled in, your ActiveCampaign subscribers won't receive a discount code. If you are not using ActiveCampaign, leave this blank.
Discount Name: Enter a label to identify discount codes in EDD as having been generated by this plugin. For example, enter "Email subscriber discount". Regardless of what you enter here the subscriber's email address will be added to the end of the discount name.
Discount Amount: Enter how much the discount should be for. Do not enter any symbols like $ or % just the number (i.e. 20)
Discount Type: Enter the type of discount you are offering - either a percentage or a flat rate.
Use once per customer: If the discount should expire after it has been used check this box.
Max Uses: If you want to make the discount available to customers to use multiple times enter how many times here.
Email Subject: This is the subject line used in the email sent to your subscribers. Something like "Thanks for subscribing to Acme Co. Newsletter" would work.
From Email Address: Enter the address the discount code should be sent from. If you have a customer support or sales address, this would be a good email to enter. Try to make it an @yourdomain.com address, as some recipients may have trouble receiving from a Gmail, Hotmail, Yahoo, etc. address.
From Display Name: Enter your name or the company name that the email should come from.
Customer Placeholder Name: Enter a generic greeting name if you are using the {firstname} placeholder tag provided. This will allow you to have a greeting to the customer if they do not enter a name in their signup.
Message: Enter the message your customers should receive in the email. Be sure to include the {code} placeholder tag, otherwise they will not receive the discount code.
