> * I have to constantly check my mails to prove I'm not dead

It nag mails you so you don't forget. Otherwise, add a reminder with a link to click on on the first of every month.

> * The other person's mail will without any doubt change if I die in 10+ years

You'll be clicking on this thing every month, I'm pretty certain if your SO's email changes you'll update it at that time.

> * Can this service live up to 50+ years? I'm really doubting that as well.

It only needs to be up when you die, again, you're clicking on this thing every month, if the service dies and you find utility in the concept, you'll find a different service to use.

> you're clicking on this thing every month

That's a huge problem. You tell me I have to click on a link at least once a month for the rest of my life.

First, I don't know if I'll have the same email for the rest of my life, if I change I'll have to think about changing that notification, that will have become spam in my mind.

Second, There surely will be a month in my life where I won't check my mails.

I can't think further, the thing has become a "hassle" that I have to constantly check and correct if someone change its mail, or in case it would think I'm dead, and this, for the rest of my life.

IMO there are better solutions for this type of problem, we just haven't found them yet.

> That's a huge problem. You tell me I have to click on a link at least once a month for the rest of my life.

shrug from the point of view of someone who has opted in, this isn't a big deal. People don't change email addresses that often, and if you're the type who doesn't check email for longer than a month, then yeah, this isn't for you.

The bigger problem is that this service is hard to test. When you really want it to work there really isn't a second chance. Which means you shouldn't be relying on this thing 100%. It's best to put something in your will and instructions in a safe place.

Maybe you're not familiar with that kind of thing. Give it time, it will become a hassle to your mind and you will opt out at some point if the service hasn't shut down yet.

> People don't change email addresses that often

Did you have the same email address 10 years ago? If so woah, I don't know a lot of people who do.

> if you're the type who doesn't check email for longer than a month

I said at one point in life. I can see myself taking the transiberian for example, travelling through Australia, etc... for a month in a big adventure without internet.

It's hard to predict what's going to happen in your life. Being sure that you'll have internet at least once a month for the rest of your life is a ... extraordinary prediction.

At least the time limit is too long to use for Suicide-note-as-a-Service. If it were shorter, I would worry about that being the primary use case for something like this.
