Yahoo also allows users to link their accounts with various other platforms like Instagram, Facebook, etc. Still, sometimes the users face some difficulties, and Yahoo mail not receiving emails from Instagram is one of them. So, to resolve this issue, check your internet connection. Check whether your receiver address is correct. Also, check your ‘Spam,’ ‘Trash,’ or ‘All Mail’ folders because sometimes the received emails are sent to these folders by default due to some incorrect filters settings.
