Automated emails for additional payment button

[Rabih12]

hello everyone, I need some help from experienced people.

I integrated the PayPal smart button with coding to my shopify store , for sure I have basic plan so I cannot add it to checkout page, but after placing a payment through this additional button the automated email are not sending,

and right now I am in Qatar so is a bit hard to find another payment gateway without paying tons of money for registration

any help or suggestions , even I have an us bank account with Wise , but the store is operated from Qatar
