About
Duobox is hosted business email for small teams that want to use addresses on their own domain. It provides personal and shared inboxes such as sales@, support@ and billing@, with shared message history and access for multiple team members. Users can connect a domain they already own or register one through Duobox, then create inboxes, aliases and forwarding rules. The service includes up to 10 inboxes of 50 GB each per person and supports additional domains. Teams can access mail in a web browser or configure a phone's mail app. Duobox also offers an MCP connection for clients such as ChatGPT, Claude and Cursor, using OAuth and configurable permissions to read mail, save drafts, send messages, or manage the team, plan and inboxes. A free tier includes one person, one inbox, one domain and 10 GB; additional people cost $2 per month each.

About
OnMail has been engineered to solve the core areas of email that are broken today. Control has been taken away from you, ad targeting has grown into an invasive norm, most email addresses that actually represent your digital identity are unavailable, and simplicity has given way to overly complicated actions in the inbox. OnMail offers a first-of-its-kind permission-based inbox, along with cool new abilities like superior search based on natural language recognition and a unique import account system that modernizes your existing email accounts in OnMail. You can send large attachments, save time with AI-based suggestions to unsubscribe, follow up on email, and perform automated inbox cleanup. OnMail’s premium service plans even uniquely allow you to acquire and integrate your own custom domain into a personalized email address. OnMail’s creators at Edison provide ecommerce research to businesses in the form of Edison Trends.
