Hello Robert,

Auth.Net: The best way to test with Auth.net is to sign up for a developer account. Once you can see the recurring Payment in your Auth.net Test Terminal, Auth.net will continue that recurring payment unless it runs out or is canceled.

Settling Credit Cards: Credit Card Payments will automatically be settled unless you have selected the "Authorize Only" Check box, in which case you will need to settle each payment manually.

Emails: Once you have configured your SMTP settings, entered a email for Store To and From E-mails, Configured E-Mail Templates ( Ex: for testing make the user email template subject "user", body test) complete checkout and see if the if the e-mails are received.

Please let me know if this helps or how I may be of further assistance. Thank you!
