Slow spinning

I have a few questions:

1. I am testing this lucky wheel plugin on my woocommerce site, how do I reuse several emails over and over again and not being marked as spam? I have deleted the emails from the email section and also in my mailchimp list, but still being marked as spam.

2. I have created several coupon code that I created on woocommerce. For the email notification, how do I put the coupon value explanation that will be linked automaticaly to the coupon code? is there any short code for this?… for example after the spin, visitor won coupon code 100OFF500, this mean they will get $100 discount with minimum purchase $500. If visitor won coupon code 10OFF100 this means $10 discount with $100 minimum purchase.

3. When I tested using mobile devices, after I submit email, the wheel spins endlessly (never end) and very slow, how do I configure this? I am using these parameter:

times spinning per email: 5
delay between each spin: 1 seconds.

is that the correct parameter? but that didnt work, the wheel spins never end and very slow
