Btc tracking and .txt delivery using HTML

Hi, my name is Isaac and I’m looking for some more information on how I can send an email with a bitcoin wallet address inside, track the status of that payment, and deliver a .txt file when payment is completed. I don’t want to use any of the already provided services like coinbase. I would assume this wouldn’t be too hard but I’m not sure. Any help or directions would be great!

Love ya guys- Isaac
