Yahoo Email has implemented several key guidelines in 2024 to enhance user experience and email performance. First, users should maintain less than 90% storage capacity to ensure smooth operation. Additionally, Yahoo now recommends using strong, unique passwords with at least 12 characters for enhanced security. Furthermore, the platform supports up to 25MB for email attachments, though users should compress larger files for optimal delivery. To prevent spam filtering, Yahoo suggests limiting mass emails to 100 recipients per message. Moreover, users should regularly clear their spam folders every 30 days to maintain inbox efficiency.
