If this is a joke, then I admit it made me crack a smile. If not, please don't email a marriage proposal, no matter what century we are in.
lol, her parents are in out of country so i have send mail related this i can write it from my heart but if there is any example for beginning that will helps me.
my situation is good to send mail to then instead twitter/sms ..., i didnt fail just googled some words i already sent, wait .....
Lol, however I take your problem seriously and I think if you cant write yourself then try fiverr.com to find someone to write for you
Respected Mr. & Mrs.(Insert parent's name here) I hope you are fine and enjoying your life. I am sure (insert your gf's name here) has told you about me already. I am a very successful (insert your occupation here). I make more money in a day than you would make in a month. We have been fooling around for quite some time now and we are really enjoying it. And WE have decided to spend the rest of our lives together. You see both of us are really fond of each other. I hope you understand that your daughter won't find a better guy than me. Although me and (insert GF's name) are old enough to make such decisions of our lives ourselves but still I would like your approval on this because we both need your blessings. Please let me know if you are coming on our marriage ceremony or not? Thanks (insert your name here)
Tell them you will take care of her and cherish her for the rest of your life, if you really plan to write this email.
