If you've unblocked a sender but their messages still aren't appearing, consider these common causes: Emails are not received in Yahoo Mail
Here is the detailed text guide for both scenarios.

Under you can add or remove entire domains (e.g., @example.com) by tapping the X or Remove button. Troubleshooting: Still Not Receiving Emails?
You’ll see a list of blocked emails or domains. Find the one you need to unblock — maybe that colleague whose reply kept bouncing, or a store you actually do want to hear from.
In Settings, look under “Managing your account” or “Advanced” — on most recent versions, tap Blocked addresses . (On some older layouts, it might be under “Security and Privacy.”)
