You don't need to have hotmail or outlook express to receive email alerts from Trulia - and those alerts should be delivered to you. The updates you see on the Trulia homepage are specific to the regions in which you search but may not be as specific as some of the home searches you've performed on our site.
I've confirmed that you are signed up to receive email alerts so if you still aren't receiving them, please contact our Customer Service Team so they can investigate further. Just access the link below and select the 'Ask a Question' option.
Thanks for your patience, and please let us know if you have any other questions or concerns.
