"I've been getting lot of promotional emails recently which fall into my Gmail inbox (rather than spam folder) hence triggering a notification. I've never subscribed to these emails." - how do you think, where do they get your info from? why are they spamming you (in your opinion)? I would suggest you to hide your email somewhere on your site/blog. And make it look it like "name [at] gmail [dot] com". They would need to find your email before spamming you

Been using the same address for 8 years so I think maybe it's been in many email-dumps which are usually sold for email marketing campaigns.
