BACKGROUND NOTES

1. The data on this page is compiled from publicly available information and has not been audited or independently verified in any way.
2. User counts are VERY slippery. One provider may count only active users, another may count anyone who ever signed up for an email address, even if they only logged in once five years ago! Also, the definition of "active" can vary wildly, so the above figures are best treated as order-of-magnitude estimates
