I am an email subscriber. Lately your news letter has been coming almost every other week as apposed to every week. Why?
Nine times out of ten if you didn't get Ask Leo!'s weekly newsletter it's because it was erroneously filtered as spam.
Check your spam or junk mail folder and see if it was placed there. If you find it there and your mail service or program supports it, make sure to check "This is Not Spam" or the equivalent.
To reduce the chances that this will happen again be sure to add "firstname.lastname@example.org" and "email@example.com" to your address book, and any whitelist option that your mail service might provide.
If this happens more than 2 or 3 weeks *in a row*, drop us a line saying so, and we'll see if there's any more information we can gather. (Just use the ask a question page.)
In the mean time, remember that you can always read the most recent newsletter on-line here: http://newsletter.askleo.com.
