I am currently facing a problem where the verification email sent after registering does not get delivered to @hotmail.com email addresses, not even to the spam folder. The verification email works perfectly for @gmail.com. What causes this, and how can I solve it?
TL;DR
Verification emails are not being received by @hotmail.com email addresses, but work fine for @gmail.com. This could be due to email filtering settings on the @hotmail.com accounts. To solve this, recommend developers check their email deliverability settings, ensure the email is not marked as spam, and consider whitelisting the sending email address.
