In addition to Mayer himself creating a TikTok account, Columbia Records also pushed a marketing campaign revolving around a 1980s advertising aesthetic. Two months before the album released or was even formally announced, posters appeared in various locations in cities around the world. They all described the sound of
Sob Rock but never explicitly confirmed ties with Mayer releasing an album. A site called sobrock.net went up around the same time, with a newsletter sign up and a copyright for "John Mayer Enterprises". On June 1, 2021, Mayer finally confirmed that his new album was indeed called
Sob Rock, and additionally gave the release date and cover. From there, Columbia went public and posted 1980s themed billboards and posters to promote the album and single, "Last Train Home". Those who had previously signed up for the website newsletter received a zine focused around the album in the mail. After "Last Train Home" was released, Mayer released a music video for the single and then performed the song on
Jimmy Kimmel Live! on June 7, 2021. When the album was officially released, Mayer went on
The Tonight Show Starring Jimmy Fallon and performed the songs "Shouldn't Matter but It Does" and "Last Train Home". The day after this he confirmed numerous tour dates across America for a Sob Rock Tour in 2022. The cover art of the album varies between streaming platforms. In the upper right corner, below the "SOB ROCK" text, a sticker unique to the platform the album is being streamed on is displayed. Spotify, Apple Music, Amazon Music, Deezer, and YouTube each have unique stickers, while SoundCloud, Pandora, Tidal, other services, and physical copies of the album have no sticker at all. Mayer further went on to release "Wild Blue" as a single, which received an accompanying music video on August 18, 2021. ==Critical reception==
