Help With Oldies song

A woman sings the song. I think it goes something like this.
I'm sending you my love or I send you all my love. I heard it in a movie and I can't remember which one. Maybe a wartime goodbye. Could be WW1 or WW2.
Pls. Help. Would be satisfied with singer and title.

not sure if this is the right title or not, but there are both male and female versions of it.

sealed with a kiss.

it says:

though we've got to say goodbye for the summer
darling i promise you this
I'LL SEND YOU ALL MY LOVE
every day in a letter
sealed with a kiss

if that is the song, then you can probably find a version by bobby vinton, the original artist.

GOOD LUCK
