amtm I want to leverage the email function within amtm

[Ripshod]

I'm adapting a little script to notify me when a file changes (comparing md5 checksums) but it was originally written to use sendmail (built into asuswrt/busybox). Needless to say it fails. What I'd like to do is use the email functionality in amtm to handle emails, but I just don't know where to start (my sending email is already set up and working in amtm).
Any pointers?

Look at the code of other 3rd-party scripts such as MerlinAU or BACKUPMON that have incorporated this functionality.

Like to see a clear answer on this myself. In the meantime here is a snippet of what I came up with that works.

[email protected]

      NEW_ADDR=`cat /opt/ipchange/last_ip`
        {
         echo From: rt-be88u.dbonenet.com
         echo To: [email protected]
         echo Subject: External IP Address Change
         echo
         echo -n New IP ADDRESS:
         echo ' [ '$NEW_ADDR' ] '
        } | /usr/sbin/sendmail  -H 'exec openssl s_client -quiet -verify_quiet -tls1_3 -CAfile /opt/etc/ssl/cert.pem -connect mail.dbonenet.com:465' $M_ADDR 2>/dev/null

MerlinAU actually has all the email code integrated directly into the add-on, which may be a bit trickier to digest, but removes any dependencies on external code for MerlinAU.
However @Viktor Jaep 's BACKUPMON uses the Shared Email Library from @Martinski , which is what I would recommend as a starting point and is the simplest implementation.

The library is specifically designed to be a detached "all-in-one" solution other scripts/add-ons can call on to leverage email functionality:
