EDIT: Thanks y’all! I got this working by installing mutt and configuring it with my Gmail info. Please note the warning from u/jherazob below–if this were something mission critical I would not want to rely on this solution.
================
Noob question incoming, thanks in advance for any help with this!
I have a specific use case in which I want to send an automated email or text to myself once a day (the message is different each time–otherwise I would just set an alarm, lol!). I’m running Pop_OS on an old desktop computer. Where I’m stuck is getting an email to successfully send from the command line. I’m looking for easy-to-follow instructions that would help me do that, and none of the articles or videos I’ve come across thus far have helped.
I’m aware of Twilio and other services that send SMS messages, but I’m looking for something free. Especially since I only need to text one person (myself), and infrequently at that.
Below is my attempt to send an email with the telnet command. Nothing ever came through…
XXXXXXXX@pop-os:~$ telnet localhost smtp
Trying ::1...
Connected to localhost.
Escape character is '^]'.

You could probably do something with tasker to create these daily notifications
You’re going to have to use an external service for email perhaps connected to something like Postfix or just using the email provider’s API - something else to think of if you just need something on your phone as a message / reminder is to use KDE Connect like in this tutorial https://doronbehar.com/articles/using-kdeconnect-to-comfortably-send-sms-messages-from-the-shell/
Standard tool to send email is mailx, it is also often aliased as mail.
Lots of valid suggestions already here. But I’ll throw one more to the pile. You could use the Pushbullet free plan (100 notifications per month). And then either use a python library or Google for a bash script to help with getting the notifications out. Then have Pushbullet installed on your phone.
Implementing a telegram or discord bot might be easier
