Coupon Email:WooCommerce Photo Reviews – Review Reminders – Review for Discounts

Hi Support Team,
Hope you are doing well

I have purchased plugin “WooCommerce Photo Reviews – Review Reminders – Review for Discounts”. In this plugin when user gives review on site, then coupon email goes to user email. But in my case size of site logo in email is too much lengthy and expiry date of coupon not sending in email. Please see screenshot bellow:

Please help me for sending coupon expiry date and size of logo will be customize. Its very important for me.

Thanks
