When customers purchase or refund your offer, they will receive transactional emails from CartMango such as an access & receipt email or refund notification email.
On CartMango, we will send the transactional emails from our address ([email protected]), but use the seller's name so the buyer won’t be confused.
Here’s how it looks like in the customer mailbox:

The reason why we use [email protected] as the "from email address" is for email deliverability purposes.
Even though the "from email address" for the transactional emails is from [email protected], when your customers click “reply” to reply the email message, they will receive an email from whatever is configured as your customer support email address:

If you don’t set up the customer support email address, then the ‘reply-to’ will be set from the email address you use to register for a CartMango account.
