Multi account

  1. switcherConnect several accounts across providers — Gmail, Microsoft 365, IMAP — and work them from one place

    weight 3 · round to Superhuman Mail
    Superhuman Mailpartialclaimed6/10

    Superhuman clearly supports connecting and instantly switching between multiple Gmail and Outlook/Microsoft 365 accounts from one place (docs-12, docs-19, docs-20, docs-24, docs-40, docs-53), which covers two of the three providers in the story. However, no evidence mentions generic IMAP account support, so the 'switcher from any IMAP provider' part of the story is unaddressed. Missing for 10: explicit IMAP account support/connection, independent/hands-on confirmation of multi-provider account switching beyond vendor docs.

    Evidence only touches this obliquely: contacts management explicitly 'syncs with Office 365 and Google' (missive-docs-23), and shared/team inboxes are documented (missive-docs-32, missive-docs-28), implying multi-account consolidation, but there is no explicit documentation in the pack of connecting Gmail, Microsoft 365, and generic IMAP accounts as email sources worked from one unified inbox. Missing for 10: explicit account-connection docs for Gmail/O365/IMAP email (not just contacts sync), and confirmation that all provider types can be combined in one inbox view.

Portability

  1. switcherMy mail stays reachable over open protocols and standard formats — IMAP/JMAP/SMTP access and standards-based export — so no client can lock me in

    weight 2 · round drawn
    Superhuman Mailnone0/10

    Superhuman is a proprietary client layered on top of Gmail/Outlook accounts; the evidence pack contains no mention of IMAP/JMAP/SMTP access, standards-based export, or any data-portability guarantee — only MCP integration for AI assistants and account switching between Gmail/Outlook. No documentation addresses protocol-level openness or export, so switchers have no evidence their mail stays reachable outside Superhuman's own app.

      Missivenone0/10

      The evidence pack contains no mention of IMAP, JMAP, or SMTP access for user mailboxes, nor any standards-based export functionality; all connectivity evidence is about REST API, webhooks, and MCP integrations for AI/automation, not about open mail protocol interoperability or data portability for switchers.

        Superhuman Mailnone0/10

        Superhuman Mail is a cloud SaaS client layered on top of Gmail/Outlook accounts; there is no evidence of any self-hosted deployment option, open-source server, or ability to run the mail pipeline on infrastructure the user controls. All evidence points to a hosted, proprietary service with no self-host path, so this axis is not delivered.

          Missivenone0/10

          Missive is a cloud-hosted SaaS collaboration/email platform with no documented self-hosting option; community evidence confirms mail data routes through Missive's own servers (missive-comm-1), and no docs mention on-premise or self-hosted deployment.

          The probe explicitly shows llms.txt returns 404 and no agent-oriented docs (openapi/well-known) are found; while an MCP server exists, there's no evidence of llms.txt or similar agent-discovery docs a user could point an agent at.

          Superhuman Mail is a GUI email client with an MCP server and agent triggers, but there is no evidence of a CLI, API, or documented mode to run the product headlessly or invoke it from a CI pipeline — probes for llms.txt and OpenAPI specs both returned 404. The story is plausible for an AI-native product with automation features, so it is not out of scope, but no evidence supports the specific headless/CI capability.

          Missive exposes a REST API, webhooks, and a documented MCP server that let external systems and AI agents trigger actions without using the UI, which could be scripted from CI/automation pipelines. However there is no evidence of an official CLI, headless mode, Docker/container deployment, or CI-specific documentation/examples for running Missive itself in automated pipelines.

However, hands-on community reports are split: some users call it 'blazingly fast' (comm-9), while at least one ex-user reports search taking ten seconds vs instant in Gmail, directly contradicting the 'never wait' claim (comm-7), and another calls the UI just a 'cuter UI' around Gmail features with no real speed edge (comm-12). Missing for 10: a documented exhaustive keyboard-shortcut reference beyond the command palette, and independent benchmark data resolving the conflicting speed reports.

However, there's no comprehensive shortcut list, no dedicated performance benchmarks, and community comments call the UI 'unintuitive' with 'design flaws' though also 'snappy' — mixed signal on speed/polish.

However, this is built on individually-owned mailboxes with cross-visibility signals, not a true shared/group inbox or shared account model where the whole team works one conversation queue with assignment/ownership.

However, there is no explicit mention of a 'snooze' feature to temporarily hide a conversation and resurface it later, which is a core part of the story. Missing for 10: explicit snooze/defer-conversation functionality, independent/hands-on confirmation of the follow-up reminder behavior.

                                                          Missive's docs clearly document snoozing a conversation until a specific time so it resurfaces in the Inbox, including quick access via swipe or command bar (missive-docs-supp-1, missive-docs-supp-2). However, there is no evidence of a distinct 'follow-up reminder' feature that resurfaces a thread specifically if nobody replies (as opposed to a fixed snooze time) — the story's reply-tracking trigger is unevidenced. Missing for 10: documentation of a no-reply-triggered follow-up reminder mechanism, and any independent/hands-on confirmation of snooze/reminder reliability.

                                                          Superhuman documents AI-driven Auto Archive and Auto Labels that batch-classify/archive whole categories of mail automatically, plus a command palette (Cmd+K) said to 'instantly do any action,' and split-inbox tabs to 'get through emails of the same type, at the same time' — all of which gesture at bulk triage outcomes, but none explicitly describe a manual multi-select-then-archive/label/mark-done workflow across many conversations. Missing for 10: explicit documentation or independent confirmation of manual multi-select bulk actions (checkbox/shift-click select many threads, then batch archive/label/mark-done in one keystroke).

                                                          Superhuman explicitly documents 'split inbox' functionality with custom categories like VIP, Notifications, Calendar, and Team, plus custom Auto Labels that let users organize incoming mail into tabs by type so triage happens by focus area rather than arrival order. This is a first-party documented feature with a dedicated blog post, not just a vague claim. missing for 10: independent/hands-on confirmation of the split-inbox feature specifically (community evidence covers other aspects of Superhuman but not this feature) and detail on how priority ordering interacts with arrival order within each stream.

                                                          Missive's docs mention rule automation (up to 1000 rules), team spaces, and shared/team inboxes, which could be used to organize conversations by category, but there is no explicit documentation of a dedicated 'streams' or 'focused inbox' feature that lets a user split a single inbox into priority-ordered views (important, team, newsletters, calendar invites) as described in the story. missing for 10: explicit inbox-view/stream creation feature, priority-based triage ordering, and evidence of calendar-invite handling as a distinct stream.
