The fine folks at Fastmail have upgraded the quotas on their accounts, and I couldn’t be happier. As storage space gets ever cheaper, this is the thing to do. [I'm an obsessive email storer, and I still haven't run out of room.]
Not only do I use Fastmail, but my whole family does. Mom can attest to the fact that it works.
If you’re thinking that this Fastmail thing might be cool, there are special upgrade prices available now through the end of November. Seriously, if you care about email, it’s worth it. [Shameless affiliate link is here if you want to give me a kickback, eh?]
