I've just had an email from Purple Parking having used them in the past to book airport parking. However, as always I requested NOT to receive unsolicited emails from them.

I've just had a spam email through that's clearly from Purple Parking promoting a new(?) cashback site. Given I requested not to receive emails in the first place, this shouldn't have come my way and they are actually promoting something that potentially takes money away from those that promote them.

Anyone care to provide feedback on this? Unsolicited mail from a merchant promoting a cashback site - not very good at all
