Jesse James' Ex -- Get Sandra Back!

Jesse James' ex-wife sent him an email, telling him how their daughter aches to be back with baby Louis, and that she hopes Jesse gets Sandra Bullock back.

TMZ has obtained a copy of the email, sent by Janine Lindemulder to Jesse last month.  In the email, Janine says, "I believe you are a good man and with all that has happened you are now much wiser and if given the chance with your wife again, you would not screw it up."

Janine not only gives Jesse permission to move with their daughter to Austin, she says she'll follow along.

And, Janine says, "Sunny talked about 'Louie' [sic] yesterday, she told me he doesn't like baths.  She loves and misses her baby brother."

The email was submitted by Jesse as evidence in their custody war.
