Not long ago I published my official resignation letter to The Church of Jesus Christ of Latter Day Saints. Yesterday I received my reply from the Church's Office of Confidential Records and today I responded back. You are more than welcome to read the entire discussion and I hope that my efforts will be of some use to you.
Just so we're clear, I have actually been able to use e-mail for almost this entire process. If anyone wants to resign their membership with the LDS Church but doesn't want to use a stamp you can use this e-mail address: msr-confrec@ldschurch.org
I received the response to my resignation letter via postal mail though so if you want to keep digital records of everything you'll probably need to use an app like Tiny Scanner to take a photo of the letter and turn into a PDF which you can then e-mail to yourself and anyone else.
If you're playing catch up with me or just haven't read my official resignation letter you can read it HERE.
