Hi,
I wouldn't use e-mail. Instead, I'd recommend you start either a
CarePages account or a
Caring Bridge account. Your medical center might already sponsor one or the other. With these accounts, you (and/or someone else you designate) make a post, and everyone who subscribes will see it. Well, people will receive an e-mail notice whenever you create a post, then they log in to see it. They will have the opportunity to reply as well, offering words of encouragement either publicly or privately.
We used CarePages (account name: Lexi96) for our daughter and it was really a blessing to be able to keep everyone up to date with accurate day-to-day information throughout her illness.
Good Luck with whatever method you choose, and prayers of support and well wishes to you during your illness and recuperation.
