Review reminder email css

Hello,

We have just started using your plugin.

We have issues with the email:
1. Is it possible to use {site_title} and {order_id} in the email subject (just like in Woo standard emails)?
2. Please help us with formatting issues mentioned on the screenshot:
2.1. Paragraph spacing.
2.2. Overlapping price and Review now button.
2.3. Review now button text color.

Thank you,
