Twilert is a web app that allows users to track keywords in tweets and have email digests sent at selected intervals.

Features:

• register for free Twilert account (unique password created and validation required)
• select keyword(s) or phrase(s) to track and monitor on Twitter
• select intervals at which email digest(s) are delivered

The Good:

With Twilert it is easy to set up alerts (“Twilerts”) to track and monitor any keyword or phrase the user chooses. Twilert does the work of crawling through Twitter to find occurrences of those words and phrases and then emails you a digest of those tweets. Twilert is especially useful for those interested in tracking brand or corporate references (or anything like that). Advanced filtering is also possible, including for tweets from or to certain people, near a location, with positive or negative attitude, asking a question or containing links.

The Not-so-Good:

The only thing we think Twilert could improve on is the mechanism for selecting the intervals at which email digests are sent to users. No problem with the daily, weekly or monthly choice, but it only allows you to select on the hour (rather than hour and minute). Not a huge deal, but it would be nice to have that extra level of choice available.
