You may be able to get what you want with the wp_mail function built into WordPress https://developer.wordpress.org/reference/functions/wp_mail/

There could be an issue with WordPress.org rules against collecting data from the user without their consent. You may be able to get consent from some users by promising them support or some other thing of value. Just think it through clearly.

There are a bunch of email routines in my RSVPMaker plugin you can look at if you need something more elaborate than wp_mail. I've tried to enable more reliable delivery of event confirmation messages (and fewer problems with spam blockers) by having messages sent from an authenticated account. For a phone home function, might not be necessary if you just tell your own spam blocker to allow any message with the subject line provided for your own email.
