The Resend Receipt extension for Easy Digital Downloads allows your customers to resend their purchase receipts directly from your website without logging into their account. This is a great addition for stores that allow guest purchases, or do not want to require their users to log in, to be able to get a new copy of their receipt.

When logged out of their account, visitors can be presented with a form to enter the necessary information to have their receipt resent to the email address they used at the time purchase.
Additional Features:

• Integrates directly with the Purchase History shortcode in Easy Digital Downloads
• Optionally, site owners can also receive email notifications when a customer requests a receipt be resent.
• Built-in rate limiting, to prevent continually submitting the same request over and over.
• Supports enabling on a per-product basis.
