Free Translation and Professional Translation Services from SDL
I use it whenever I want to email Jacob's foster family or when they email us.
You'll get the gist of the email. It won't be perfect - but it is quick and easy!
One tip - if you want to translate something that you are going to send to someone - translate it once from English to Spanish, then translate it BACK to English to make sure it really says what you want it to. Once I thought I was saying something like "God bless you" and instead it translated to "God drinks with you." oops!
Congrats on getting an email from your son's foster family. Isn't it GREAT!?
