It's masculine form, Mael, is pronounced "MAYL", the feminine equivalent, Maelle is pronounced "May-LUH", and Maelys, as stated above, is "mayl-EESE" - two syllables.

I don't know who the heck that anonymous user is, but he/she is completely ignoring the fact that there is a diaeresis/umlaut (two-dotted accent) over the 'e', thus it is pronounced separately and there is no diphthong between the 'a' and the 'e'.
The masculine name MAËL is pronounced MAH-el. The feminine name MAËLLE is pronounced mah-EL, with greater emphasis on the second syllable. The variant MAËLYS is pronounced mah-el-EES.
