John Douglass, owner of the "jacksfilms" YouTube account, was invited to the world premiere of this movie by Sony because he praised it sarcastically since its announcement.

Sony promoted the latter release of the trailer by hosting a press conference in Cannes, the day before the 2017 Cannes Film Festival, which featured T.J. Miller parasailing in. Variety called the event "slightly awkward" and The Hollywood Reporter described it as "promotional ridiculousness."

According to T.J. Miller, this is the fastest produced animated film in history.

The film was shown alongside Puppy, a short film based on the Hotel Transylvania films.

Tony Leondis, the director of the movie, does not take emoji's seriously. He sees them as "the toys of the 21st century" and said he needed to rush the movie because "who even knows if people are going to like emoji's in [six years]".

A week before the film was released, Sony tweeted a controversial promotional picture parodying the Hulu series The Handmaid's Tale (2017). It was immediately met with criticism for being tasteless, considering the content and themes of the Hulu series. Following the backlash, the tweet was deleted.
