A Direct Message Card is an ad format with a video or image, and customizable buttons (i.e. call-to-actions). It's the best way to promote your brand’s chatbot in Direct Messages to a broad audience on Twitter.
Currently, Direct Message Cards can be used in Promoted Tweet and video views objectives.
A Direct Message Card can have up to 4 buttons, each of which directs users to a different part of your chatbot via different welcome messages. A welcome message is an entry point into a Direct Message conversation with a pre-set message that people see and can respond to, even when you may not have the ability to send a Direct Message to that person. This first message should greet them and guide them to the best ways to interact with the chatbot. Your chatbot developer will create the welcome messages for your chatbot.
Direct Message Cards are currently unavailable for self-serve advertisers. Please follow @TwitterBusiness for updates when this feature is available.
