Problem: Sites which flood the user’s email account with messages saying:-
Thank you for buying 'x'
We are going to deliver 'x' today
Our van has left the yard
Our van is in your street
'x' has just been left on your doorstep.
Do a fair bit of online shopping and this can become most of your email traffic.
Is there any need to send any of this email traffic, if a user has already set up an account on the business's website ?
