Mailbird Next unifies Windows and Mac email apps
Mailbird, Inc. has launched Mailbird Next, a ground-up rebuild of its email client for Windows and Mac on a single codebase, bringing feature parity and simultaneous updates. The free app includes a unified inbox, local mail storage, and a Privacy Hub that blocks tracking pixels and remote images. Integrations include WhatsApp, Slack, Dropbox, Google Calendar, and Asana. AI features are optional and off by default: an MCP server lets users connect their own AI, and Wingman, an on-device assistant in closed beta, summarizes emails and drafts responses. An Android app is in public beta, with an iPhone app coming soon. The company, founded in 2012 and still founder-owned, reports over 3.3 million registered users.
Mailbird Next is a meaningful product update for a niche email client, but it does not have broad impact on the AdTech/MarTech industry as a whole.

Avec launches Tinder-style mobile email app
Avec launched an iOS mobile email app that presents emails as Tinder-style swipeable cards and supports voice-based replies that transcribe to editable draft text. By default, left swipes send messages to a later pile and right swipes archive them; swiping down marks messages as unimportant and the app can group those for bulk review. Avec says having full email context enables better name recognition and tone-aware edits compared with keyboard-based tools constrained by Apple’s APIs. The app is available in the U.S. and is free for Gmail users; Outlook support is planned. Avec has raised $8.4 million to date from investors including Lightspeed and Haystack. The company was founded by Jonathan Unikowksi, formerly a product engineer at Replit.
Former Pinterest Team Launches Extra Email App
Extra is a new email app from BuildForever, founded by former Pinterest designers and engineers, that reorganizes Gmail inboxes around a real‑time "Today" view instead of traditional subject lines, folders and tags. The app uses background AI to surface actionable items, summarize important messages, and provide an assistant for finding emails, unsubscribing and voice replies. Other dedicated tabs include News, Events and Shop, which surfaces product images from shopping emails. Extra is launching on iOS and web to waitlist users (invite codes) and currently works with Gmail only. BuildForever raised $9.5 million in seed funding led by Abstract, A* (Kevin Hartz), Felicis and Elad Gil; notable angels include Pinterest co‑founders Ben Silbermann and Evan Sharp, Gmail creator Paul Buchheit, Fidji Simo and Shishir Mehrotra. Extra is free for now with monetization planned later. Publication date: 2026-04-21.
Mailfo v2.0: Local-First Disposable Email Android App
A developer published Mailfo v2.0, a privacy-focused disposable email client for Android engineered around a local-first architecture to minimize network latency and preserve ephemeral data. The app uses Jetpack Compose for a single-activity reactive UI, a Room (SQLite) local caching layer for inbox summaries and message details, and an identity state management system that stores previously generated addresses in a profile tab for quick reactivation. Features include custom vs. random addresses, real-time incoming mail operations (read/unread, starring, sharing), global localization across multiple languages, and a direct settings option to wipe local data. The project is available via a web portal and on Google Play. Publication date on the page is 2026-06-08.
