The development of Twitter’s ad product takes another step today with the launch of Scheduled Tweets.

This gives advertisers of all sizes the chance to time their tweets to specific events or related ad campaigns up to a year in advance. And this is quite interesting: Scheduled Tweets can be either paid (i.e., a Promoted Tweet) or organic.

There’s also a new “Creatives” tab in Twitter’s ad management dashboard that advertisers can use to manage these Scheduled Tweets (and manage their Twitter Cards, too). That’s where the advertiser can schedule future tweets via the blue “Compose Tweet” button. That leads to a new interface with controls for Delivery, Promotion and Scheduling — like this:

I get the sense that brands are increasingly using automation to manage their Twitter (and other social network) accounts, so it’s wise for Twitter to give them the opportunity to automate ad launches, too. That’s how Twitter is touting the new feature:

With scheduled Tweets, you can publish content at any time without having staff on-call to Tweet on evenings, weekends, holidays, or other inconvenient times. Advertisers also gain the flexibility to plan content in advance for events like premieres and product releases.

Scheduled Tweets are available to Twitter advertisers in all supported languages.
