Difmeil

Difmeil is a Chrome extension that combines multiple Gmail accounts into a single, unified inbox. It's built for people juggling several Gmail accounts—personal, work, freelance—who lose track of emails across different browser profiles and tabs. The tool merges messages by date across accounts while still allowing individual account views, offers customizable native notifications with sender/subject rules and do-not-disturb schedules, and supports composing, replying, and forwarding directly from the correct account. Users can personalize colors, aliases, and themes. Difmeil emphasizes privacy, noting it uses no proprietary servers to store email. It's free for up to five accounts, with no credit card required to start.
