We sought to solve the issue with Gmail retiring POP3 fetching and have created a full email system that checks any accounts you have and aggregates it into one online inbox that is accessible from anywhere. It also supports IMAP, and is great for people who have many email addresses or clients and they want to be able to manage many identities from one web-based location. Have you used Gmail's fetching system? And what are you looking to do now that it is retiring?
Pop3.io brings the power of a desktop client to your browser. Connect your IMAP/POP3/SMTP accounts and manage all your identities from one secure, unified web inbox. Perfect for freelancers, agencies, and privacy-focused power users.
