I wish The Economist was so careful when emailing me. I frequently get spam from them about 'exclusive subscriber only events' with no unsubscribe link because 'This service email [sic] contains important information about your subscription.'

Reminds me of my bank. Whenever they change their terms of service or do anything that could affect my account they send an automated notification email that pretends to have been sent by an actual employee, and always with a subject line like "XYZ sent you an important message regarding your account".

As any UI designer knows, if everything is important nothing is important, and so I just treat those as the spam they are. Which lead to a legitimately important mail getting lost, but it only caused problems for them so ironically they shot themselves in the foot with their dark patterns.
