please don't send advertisements (e.g. for some credit cards) in the paypal notifications. This feature should be restricted to important messages about compromised accounts and unusual activities and the like, not to spam your customers.
If you send your spam there, then people won't care about the notifications anymore. It gets a bad reputation.
Thank you for your contribution to our online community.
The settings you want to receive messages can be made in your PayPal account yourself. To do this, go to the settings-notifications-marketing settings-on the blue marked what information - now you can change your advertising settings independently.
