If I reply to an email, can I say I revert to you? Does "revert" have any meaning related to "reply( to an inquiry)"?

A contact wrote in reply to my email:"I'll revert to you, if need be." And I found the "revert" was a little off to my ear. I saw little of such uses, except another time quite a while ago and the then author seemed from the same region.

I’m learning English. If u find anywhere I can improve my composition, Pls do let me know. Bow.

Do inform me if you see any corrections needed in my written English.
