I just use canaries. somename@mydomain.tld and if the business allows itself to be compromised they are notified and nullified. I've recent had to make the canaries less obvious as some companies are getting annoyed and marking any email address with their name in it as fraudulent despite knowing full well the intended use case. As for providers, half of my domains are just pointed at a tiny VM and the other half are on fastmail for family members to use provided they continue to maintain their customers best interests.
