LFS = Looking For Service

TL;DR: can you recommend me a service to send myself emails at a later date that works like a time capsule so that the email can not be deleted or seen by someone else (except the service provider obviously)?

LT;MR(= Long Text; Might Read): Lately I've been trying to pay attention to the passage of time by celebrating the solar-events (summer/winter solstice and autumn/spring equinox).

For this years autumn equinox celebration I would like myself and my guests to send ourselves an email that arrives a week before next years spring equinox to our own email addresses.

The prompt will be: What would you like to do more of this coming summer?

I understand many common email clients/providers support this natively but it's my understanding those emails end up in specific folder so they are easy to find and subsequently read and/or delete which negates the idea I want to accomplish.

So, I'm looking for a service to store and send those emails to me and my guests in time for next years spring equinox.

Thank you 🥰

Hello,

Edit2:

After some time has passed since the quite scary and depressing incident that happened to my mother and that promted my original post it is quite clear that this is not something that can be fixed with more technology.

There are a couple of small and reasonable adjustments that can be made but other than that this is a human 'problem' that requires humans.

So I'll try to get my mother more services with people coming to her place to help and to check up on her. I will also go there more myself and help her cook, clean, shop, etc (and ultimately I suspect I'll have to move in with her for the end of her life).

Thanks again to everyone that got involved

Edit:

It's evident that I’m having trouble to define my needs and wants in this domain, probably because I know too little. I’m learning a lot and hopefully I will be able to ask better questions soon.

I think that what I'm looking for is a wearable basic phone to receive and make calls.

Something like https://xplora.se/product/xplora-xgo3/ (Swedish, didn't find in Englis ) or maybe even https://www.doro.com/en-gb/products/smart-devices/smartwatch/ but with less vendor lock in.

It seems that having it be a 'real' phone is less common than I thought but connecting to another mobile device with Bluetooth is more common, and I guess functionally there isn't much difference

Obviously I don't expect to find something that fits perfectly, but by aiming high I hope to find something useful

/Edit

I've just started to look into smartwatches and wonder if you could help me with your prior knowledge and experience.

I have some things on my wishlist, but it's hard to understand if they are reasonable and what to look for in all the sales copy and vendor provided specifications.

I know basically nothing in this domain.

Extra background, for context

.

• What I require:
  • phone calls and text messages by cellular tech[1] (Edit: maybe this is not as easy as I thought initially, it might be more like a wish than a requirement)
  • long battery time
• What I wish for:
  • ability to turn stuff off (either in the stock OS or with alternative OS that is easy to install), specifically health stuff[2]
  • ability to manage the watch remotely so that I can help her keep it updated.
  • budget suggestions rather than premium.
• What I'll avoid:
  • Vendor lock ins like subscriptions.
  • Apple products.

Well, I think that's it, thanks for reading and I'm looking forward to your suggestions and ideas.

[1] I'm not sure what the correct English term is for the tech... but using a SIM-card that connects to cell-towers using GSM/edge/4G/5G or similar.

[2] It's my understanding that these kinds of watches can be used to track and monitor health statuses like SpO2, heartrate, etc. I don't want her to monitor those unless there is a sure way to connect them to health and/or emergency services.
