I know this might be a topic for WooThemes, but I wanted to know if you have any insight on how to prevent WooCommerce from sending two e-mails when an order comes through. I think it might be a SMPT issue. Please let me know if you have any suggestions!
Unfortunately I don’t have any good suggestions besides checking with your host to make sure your servers mail settings are set up correctly. If you do find a solution, I would like to know what it is as well :)
