You can customize all the emails and landing pages that your payees see while redeeming their reward through Ethnio. There are multiple emails, depending on the method they choose, and a few different web pages they go through to choose their methods. Feel free to leave our defaults if you don't want to hassle with this at all.
One important note: be careful changing the reply-to email address to anything besides [email protected]. We help payees 24/7 with any issues they have choosing methods or getting their rewards, whether it's Amazon China or PayPal. The main way they ask questions is by replying to their reward emails, so keep that in mind.
