Yeah, I get similar mass e-mail, and sometimes hard copy, reminders from TIAA.
"At your current savings rate you are on track to have only XX,XXX per month to spend in retirement. Doesn't sound like enough does it? Go here to increase your monthly contributions." (Not a word for word quote as I'm writing from memory.)
Nevermind that 1) I'm maxing out what I'm legally allowed to contribute and 2) XX,XXX is significantly more than I make every month right now, before any savings, so yes, it does sound like more than enough.
