The album has received generally positive reviews from music critics. Allmusic refers to the albums as "unapologetic mainstream pop that's not heard too much at the tail-end of the 2000s" and points out that "OK Now illustrates that Jon McLaughlin has a greater gift for a big, bright hook than most of his pop singer/songwriter peers."ARTISTdirect states that McLaughlin's new style "makes much of OK Now one of those albums that could soundtrack any number of life's heartfelt moments."Jesusfreakhideout gave the album a 4 of out 5 rating, and praised the album by complimenting it on a risk that worked out well and his new style that "comes off as a clear winner and will unquestionably captivate fans until the next time around." It does pity the fact "Smack Into You" was not included on the album, by describing it as a song that "literally defines Jon's entire musical substance". The song was re-recorded as "Smash Into You" by R&B/Pop singer Beyoncé and was included on the deluxe edition of her 2008 album, I Am… Sasha Fierce.
Stereo Subversion was less enthusiastic though, stating "the album suffers from a serious case of disorganization and drag" being "heavy on cheesy diary-entry balladry" and finally stating that "the album shows little of what makes Jon McLaughlin such an interesting songwriter, and it’s sad to think that the first introduction much of America will get to his music is this mediocre mess."
OK Now debuted within the top 50 of the Billboard 200, at number forty-nine (#49), marking his highest debut to date, selling over 10,700. The next week though, it dropped to number 188, selling over 3,000 in its second week, to come at a total of nearly 14,000.
