If you do this in a loop you all ADD headers with every loop cycle.

Better do this:

$headers = [
    'MIME-Version: 1.0',
    'Content-type: text/html; charset=iso-8859-1',
    'From: michigan@xxxxx.org',
];

Don't you see that the second mail has every header twice?

This is because of the reason I explained above.

Don't get me wrong - but at this experience level you should not create
scripts which send e-mails at all. By sending a lot of e-mails this way
your provider or hoster will soon be blocked because of outgoing spam
from his network. You also need to check how many e-mails per hour are
acceptable for your hoster/provider and you also need to add certain
headers to indicate that the e-mails are either transactional or
originate from a subscriber list.

Maybe using a service like Mailjet, Sendinblue, smtp2go etc. and the
respective API of these services is the better choice for you.
