you first need create method in bookmailer if it's not there, parameters want send user:

class bookmailer < activemailer::base   def booklist_email(email, title)     mail(from: 'me@me.com', to: email, subject: title)   end

then deliver mail:

bookmailer.booklist_email(@user.email, 'hello customer!').deliver
