The title song has the distinction of not have been released on any of Olivia's international studio albums, although it did show up on her first international hits collection, "First Impressions", and was slapped onto the end of her next studio album, "Have You Never Been Mellow", when that was released in Australia in early 1975.

[2] Both songs reached the top 10 of the US Pop, Adult Contemporary and Country charts,[2] affirming Newton-John's status as the top female country-crossover star of the day and continuing the chart hot streak begun with the Grammy-winning "Let Me Be There" the previous year.

While the artist does not have the most powerful voice in the world, she makes superb use of the range she does have and the production of John Farrar and Bruce Welch help.

"[6] AllMusic editor Joe Viglione wrote in his retrospective review that "If You Love Me Let Me Know works on many levels, and is a strong chapter in Olivia's catalog....The album is beautifully produced by John Farrar with his friend Bruce Welch of Marvin, Welch & Farrar fame helping out with the production on two of the tracks, Gerry Rafferty's "Mary Skeffington" and Olivia Newton-John's sole composition, the acoustic "Changes."

The singer is a very good songwriter, and why she didn't put more songs together, or cover some of the wonderful material her mentor was releasing elsewhere, is something to speculate.
