For me email is the best, and only, solution for anything important. What would be better, a text message? a phone call? smoke signals? If you send me a physical letter and require that I'm home to receive it, not lose it in my piles of unopened mail, and reply eventually (with a physical mail? lol) it's already a lost cause. Most likely I won't be able to take any note during a phone call, if by the most unbelievable chance I am able to pick up when you decide to call impromptu. Text message, seriously? It's just for spam at this point. It's just the worst 'technical' solution. Unsecure, not travel-proof, etc... An email leaves precise traces (when, who) can be archived, searched, muted or prioritized as I see fit. You can put text picture & urls inside & whatever else, that I can lookup on my own time. If it's at all important : Send an email, then send follow-ups when it looks like the matter's urgency needs it (because as you said, obviously you can't assume I'll read it immediately and then remember it). If it's important -to you- the onus is on you to pick the best technical way to deliver information, and then insist until you get your answer.
