Until now, bots from brands assisted you in making purchases on Facebook Messenger, but from now on these bots can directly send you advertisments and subscription messages. If you’re worried about spam, Facebook has emphasised that the user is in control. Also, no promotional content is allowed, Engadget.com reported on Thursday. “All conversations between businesses and people must be initiated by the person receiving the messages, who can then mute or block the business at any time,” Facebook Manager Seth Rosenberg said. Subscribers to any brand’s Messenger feed will get messages unprompted and more regularly.
