Email change on account w. middleman

[Gus_G.]

Hello epicnpc team,

just a question concerning the sale of an online account. When the buyer wants to change the email of the account, whats the best way to do this with a middleman?
Looking at an MTGA account you have to write the customer support these information

So how can you combine this the best way with a middleman?

Best regards

The MM will created a new email for the transaction. Once payment is completed, the MM will then give the buyer this new email account along with the MTGA account. The buyer can then change the email again if they wish.
