Best way to send messages from App



I implemented a “sign with twitter” link on a website using OAuth. Now each registered user can create a watchlist, and there will be a cron job that needs to announce each user when something in his watchlist is changed.

That being said, what’s the best way to make the communication between the app and the user ?
I’m thinking direct_message but i think i’m going to have to send more than 250 per day



Twitter doesn’t have a great means for app-to-user direct broadcasting. You may want to request your users’ email addresses if you need to keep in contact with them outside of Twitter. Otherwise, you can use a conservative approach with mentions and DMs and require (& inform) that your users follow a specific account.
