Just a perspective from the other side of the coin: I host various services for schools like online registration for parent - teacher conferences. When the platform is live hundreds of parents are logging in, choosing their appointments and have to confirm them via email (only one email per person not per appointment)
And Yahoo is the Single worst email service to send to. I have correctly configured sfp, dmarc, dkim, reverse dns for the Mailserver and have tested the wording with multiple mail testing services to make sure it doesn't have keywords that get automatically flagged.
And yet after like 50 emails to parents with yahoo email addresses they are giving me errors because of "unusual volume of emails from your domain"
There is no form, no human to talk to and they just block you.
Angry parents come to me or course because they never redeived the activation link so I had to put up a disclaimer stating that if they should not use a yahoo email address if they have a different one
