@chrisod @davetroy @Lxtruong Gmail gained prominence by actually offering 1 gigabyte of space when everyone else was offering 4 megabytes. I switched to Gmail then & Google later on kept sweetening the deal.
I hated ads so I paid for extra storage & I think I currently use about 200 plus gigabytes total of space (across photos, Gdrive & Gmail). I only pay $10 per month for 2 terabytes of space.
