MyColdInbox
MyColdInbox is a web-based shared inbox and email management platform for teams handling cold-outreach replies across multiple sending accounts. It connects Gmail and Google Workspace, Outlook and Microsoft 365, and compatible IMAP/SMTP mailboxes, bringing incoming messages into a unified workspace with each message linked to its source mailbox. Teams can filter and search conversations, label replies, assign threads to teammates, add internal notes, and reply from the original sending account. Role-based workspaces support agencies managing client inboxes, as well as sales development, lead-generation, recruiting, and founder-led outreach teams. MyColdInbox manages replies rather than sending campaigns, allowing teams to keep using their existing campaign tools. It also includes thread status tracking and shared or personal inbox visibility settings.

SEDNA
Cut down email volume by up to 95% and get one source of truth for all conversations, data, and documentation through shared team inboxes. Unlike siloed email accounts, SEDNA gives team members controlled transparency of all correspondence, attachments, and actions taken within a project or message thread—along with quick composition and sharing capabilities—for more efficient communication and effortless collaboration. Each email within a team inbox has its own activity panel to host internal conversations, contextual data, and time-stamped activity that enables team members to work with—and around—one message in place of forwards, reply-alls, and cc’s that bloat email volume. The Activity Panel lets you see automatically generated or manually applied message details like category tags, job references, and people involved, as well as who viewed the message, who replied, and how so. And collaboration is easy with the ability to tag others and add comments for real-time discussion.

Inbox Works
Inbox Works is a browser-based shared inbox in development for teams that answer a shared address such as support@ or hello@. It keeps conversations visible until they are handled, shows which teammate is composing a reply, and warns before a second response is sent. Teammates can discuss messages privately beside the email, hand conversations to an owner, and use keyboard shortcuts to move through the inbox. Follow-up tools bring a message back on a chosen date or when a reply is overdue; a promised date remains even if the recipient replies first. Optional add-ons include snoozing, signatures, and rules that move selected messages to Done. It is designed for teams using Google Workspace or Microsoft 365, without a ticketing portal. The next email and reply open in under a tenth of a second. Teams can request free early access by approval, and a no-sign-up browser demo uses sample email.
