In the United Kingdom, "When I See You" returned Gray to the top forty after "Sexual Revolution" fell short by several places. It became her fifth top forty hit and her seventh top seventy-five hit there. The single was a muted success in the United States, however, reaching number twenty-three on the U.S. Hot Digital Tracks while failing to chart on the Billboard Hot 100. The single was also a modest hit in Australia, where it peaked at number-forty.
"When I See You" was released on two CD formats in the UK and contained remixes by Bugz in the Attic and Grand Style along with two unreleased B-sides, "Lie to Me" and "It's Love".
