@TiredHorse how do you know LetterMeLater won't report to the police?
I don't, with any certainty --and if you do something like title your email "My Suicide" or "By Now I'm Dead" there's a good chance it'll catch someone's attention. However, TimeCave reported me even after I had cancelled and (supposedly) deleted the email. That was for an early attempt. For later attempts I used LetterMeLater and never had the police show up.
Part of my experience was my fault:
TimeCave's user interface is confusing/crude, and so even after I "deleted" the email it looked as though it was still in the queue to be sent; I therefore contacted TimeCave to make certain the email had, indeed, been deleted --thus drawing their attention to it. It still
should have been deleted and therefore unreadable, but it clearly was recoverable and they then forwarded it to the police --which was NOT okay. But had I not made a fuss they probably wouldn't have noticed it. It doesn't change that the email hadn't actually been deleted, as it should have been, and as it was claimed it had been, but I doubt they actually go through and read every email, only the ones that catch their attention.
LetterMeLater's user interface is
much better,
much clearer, and after subsequent failures to ctb, when I had to go in and delete emails there was no question that they were no longer in the queue. Since I didn't have to contact them and make certain the email was no longer scheduled, their attention was not drawn to it. For all I know they're as sloppy as TimeCave, but their user interface makes it easier for me to compensate and avoid any nosiness.
