Sounds like FutureMe is exactly what you're looking for.

I may be under thinking this, but couldn't you just schedule an email to be sent on that date using whichever email provider/client you use?
Thanks, but not really as the "time capsule" feature would be lost since the email would be sitting in my future-/scheduled-folder.
But in the end that might be what I end up doing if I can't find a suitable service.
Kinda what I figured. I was going to suggest a shared mailbox that could be unlocked with a password that is behind some kind of time gate, but I found this site:
I know nothing about it, but seems to do what you need
Never tried it but found this while searching for "delayed email service"
Thanks, this looks promising, I'll investigate.
But also thanks for giving me the word "delayed" to use in my searches. Sometimes it's hard to remember good synonyms.
I think my email service does something like this, though I don’t use it.
Proton's implementation isn't like a time capsule, it's meant for just scheduling emails to others, not yourself. Scheduled emails are available in their own folder, and can be edited or deleted.
Sounds like you need to write an app to do this. It seems you want to aggregate data from multiple sources, keep secret, then send.
I’m tech inclined, but not a developer, lots of low/no code solutions should let you get pretty close fairly easily.
I’ll bet you could use a jobs site to “rent a developer” and it wouldn’t be too expensive.
Or find a 3rd party to collect and schedule the email.
I mostly rely on built-in "scheduled send" features these days, but in the past (and possibly future, can't remember!) I've used Time Cave and been happy with it.
