GoodByEmail

GoodByEmail is a privacy-first email inbox cleaner. It was made for businesses who are reluctant to provide third-party access to their emails. GoodByEmail is here to make the process of cleaning up an inbox painless, quick, and privacy-focused! To clarify, we take privacy extremely seriously. GoodByEmail was designed so that you don't have to "trust" our good intentions or privacy policy. By design we can't access your organisation's emails, even if we wanted to. Our AI engine analyses your emails locally on the user's device. We never upload any emails to our servers. That's right—No OAuth tokens, no invasive permissions. Emails never leave the user's computer. Users can even use GoodByEmail offline. But here’s the real deal—while most solutions in the market are are solely focused on unsubscribes, we dive deep, providing insights into the biggest offenders filling up inboxes, not all of which are subscriptions. This helps users know exactly what to delete, giving more control, and yes, we’ve also sprinkled in a handy unsubscribe option. GoodByEmail is a guiding light for IT decision-makers, helping businesses of all sizes overcome the challenges of email overload. With its focus on privacy, security, and scalability, GoodByEmail is a must-have for any business.

Macro

Macro is the open source workspace that replaces a patchwork of productivity apps with one AI-native tool containing email, channels, docs, tasks, calls, and CRM. Each Macro Block feeds into one shared AI memory layer, so what you see is the same context Macro's agents act on and remember. The whole product is built to be keyboard-first: opening a doc, creating a channel, filing a task, or switching to search can all be done via keyboard shortcuts. With bidirectional linking, @mention anything: people, docs, tasks, channels, and calls link together automatically through any Macro Block. -Macro Docs are markdown-native documents with real-time CRDT collaboration, live agent cursors, and version history you can time-travel through. -Macro Chat is focused, Slack-like messaging, with inline replies and a real inbox instead of an endless scroll. -Macro Tasks can be created from any message in a keystroke, bidirectionally linked to GitHub so branches and PRs move status automatically. -Macro Calls are recorded, transcribed, and diarized by default, with transcripts fed straight to the agent. -Macro CRM is a self-updating, auto-enriched sales pipeline that stays current without manual data entry. Startups and the fast moving teams of today are trusting Macro to never lose context.

MacroView Mail

MacroView Mail is an email management solution for Microsoft Outlook that helps organisations file, organise, and retrieve emails consistently within Microsoft 365 and SharePoint. It is designed for teams that rely heavily on email as a record of work and need a structured, reliable way to manage email correspondence alongside documents. MacroView Mail integrates directly into Outlook, allowing users to save emails and attachments to SharePoint locations quickly and accurately. Emails can be filed using familiar folder-style navigation, making it easier for users to select the correct location without needing to understand the underlying SharePoint structure. Key email details such as sender, recipients, subject, and sent or received date are captured and stored with the email, improving context and findability. The solution supports both manual and automated email filing scenarios, helping organisations reduce inbox overload and ensure important correspondence is stored centrally rather than remaining in personal mailboxes. By keeping emails and related documents together in SharePoint, MacroView Mail improves collaboration, continuity, and visibility across teams. Built on Microsoft 365, MacroView Mail uses existing SharePoint security, permissions, and governance controls. All content remains within the organisation’s Microsoft tenant, supporting compliance, auditability, and information retention requirements. The solution is particularly well suited to organisations in legal, financial services, government, and professional services, where email forms a critical part of the business record. MacroView Mail is developed by MacroView, an Australian-based software company with over 30 years’ experience delivering document and email management solutions for Microsoft platforms. It helps organisations improve email governance, reduce risk, and get more value from SharePoint as a central information repository.

MailCalm

MailCalm is a native macOS application that provides email round robin for Microsoft 365 team inboxes. It fairly routes new enquiries, sales leads and support requests to eligible team members, forwarding each allocation to the recipient’s normal inbox. Ordinary team members do not install MailCalm, use another dashboard or learn a new workflow. They continue working in Outlook or another chosen inbox and simply receive the emails they are responsible for. Before using round robin, MailCalm checks for existing ownership, customer replies, returning customers, specialist routing rules, individual working schedules and current availability. Managers use the macOS Control Panel to manage the team, set schedules and holidays, make someone unavailable for new work and review allocation history. MailCalm uses clear, rule-based routing rather than AI. If the Mac or internet connection is temporarily unavailable, new messages remain safely in Microsoft 365 until routing resumes.
