## Replyless

Replyless takes a different angle from the usual "AI sidecar bolted onto Gmail." It is an AI-native email app in its own right, but it still sits on top of the mailbox you already use. Gmail, Outlook, and Zoho Mail accounts are connected and merged into one list, with actions syncing back to the provider so your mail is never locked in.

The core idea is forced clarity. Focus mode turns a single noisy inbox into two tabs: Primary for people and threads that need a reply, and Everything else for receipts, newsletters, and promotions. You can also create named views such as Clients, Newsletter, or Payments. Sorting corrects itself as you move things, and urgent emails are pushed to the top of each view. Pressing Command-K opens a command centre for jumping to a view, drafting a reply, or setting a reminder.

AI does the writing and the routine work. Replyless reads the entire thread before drafting an answer in your voice, learns from your edits, and keeps saved snippets ready in the compose toolbar. Beyond that, agents can run background jobs you describe in plain language - a morning digest of unread mail, calendar, and open loops, or pushing invoices to Slack or Notion. Replyless is available on web, macOS, iOS, and Android, keeps each account's data scoped to its own connection, and states that it is GDPR compliant. It is an independent product and is not endorsed by OpenAI, Anthropic, or Google.

**Pricing & Plans:** 7-day free trial of the full Basics plan, plus a free Cleaner tier. Basics is $15 per user/month (5,000 AI credits, unlimited connections and workflow runs) or $10.50/month billed yearly at 30% off. Pro is $30 per user/month for unlimited AI usage. A $299 one-time Lifetime plan and custom Enterprise pricing are also available.

- **Focus mode with two clear tabs:** Focus mode separates people and anything needing a reply into Primary, while receipts, updates, newsletters, and promotions wait in Everything else.
- **Drafts written from the whole thread:** Replyless reads the full conversation and writes a ready-to-send reply in your tone, which you can make warmer, shorter, or firmer with one tap.
- **Auto-labeling on arrival:** Every incoming email is read and labeled on arrival - leads, invoices, and support requests route themselves, and it remembers your corrections.
- **Named inbox categories:** Create custom tabs like Clients, Finance, or Payments with sender, domain, or subject-keyword rules, and urgent mail surfaces at the top.
- **Background agents and automations:** Describe a routine job in plain language - a morning brief, sending invoices to Slack - and an agent runs it in the background with your connected tools.

**Strengths:** Works on top of Gmail, Outlook, and Zoho Mail without moving your mail; Focus mode and custom views make triage fast; Draft replies are generated from the full thread and match your tone; Background agents automate recurring work

**Limitations:** Priced per user, which adds up quickly for larger teams; Basics tier caps AI usage at 5,000 credits per month; Email-centric workflow is a big change for people deeply attached to their native client; Zoho support exists but Gmail and Outlook have the richest feature coverage

## Zero Inbox

Zero Inbox's founding principle is that an email cleaner should not be a black box. Instead of granting a tool permission to delete at will, you connect a mailbox and Zero AI prepares suggested groups — spam, promotions, newsletters, important — for you to review. Nothing is deleted, moved or unsubscribed until you approve it, and you can leave any suggested group untouched. The company pairs that with provider-based sign-in via Google or Microsoft, so you never hand over a mailbox password and can revoke access from your provider's own settings.

Beyond one-off cleanup, the product is built around recurring clutter. One-click unsubscribe handles the senders that keep coming back, with permanent blocking and a tracked history of every unsubscribe action. Inbox insights show how many messages were handled, which categories they fell into, and how inbox health moves over time — useful for spotting the newsletters and promotions that reliably refill an inbox after each sweep. Reviews quoted on the site emphasise speed and the approval step: users describe clearing tens of thousands of emails, and specifically appreciate being asked first.

Zero Inbox works across Gmail, Google Workspace, Outlook and Hotmail, and is aimed well beyond power users — business professionals, freelancers, students, remote workers juggling multiple accounts, and anyone sitting on five or six figures of unread mail. For teams and companies, the company runs a deliberately cautious engagement: start with one authorized source, one measurable email problem and one named operator, build a review queue, record exceptions, and only expand after a written closeout. The site claims more than 30,000 people have used the product, and its privacy documentation is written in plain language deliberately, so the data-handling scope is clear before you connect an account.

**Pricing & Plans:** Freemium. There is a free tier to get started, with paid plans available as usage and controls grow. For businesses, engagement begins with a bounded paid proof — one authorized source, one measurable email problem, one named operator — before any wider rollout, arranged by contacting the team.

- **Approval before every action:** Every cleanup action is proposed first. Review suggested groups, keep any group unchanged, and only then approve the delete, move or unsubscribe — the tool never touches your mailbox unasked.
- **Provider sign-in, no stored password:** Sign in with Google or Microsoft instead of handing over a mailbox password. Access can be revoked from your provider at any time.
- **AI inbox categorization:** Zero AI sorts your inbox into spam, promotions, newsletters and important, so bulk delete and keep decisions can be made in groups rather than message by message.
- **One-click unsubscribe with tracking:** Unsubscribe from any sender with one click, permanently block unwanted newsletters, and keep a record of every unsubscribe action taken.
- **Inbox insights and cleanup history:** See how many emails were cleaned, which categories they fell into, and how your inbox health changes over time.

**Strengths:** Approval step before any message-changing action, so cleanup is reviewable; One-click unsubscribe with permanent blocking and action tracking; Signs in via Google or Microsoft, so no mailbox password is shared; Access can be revoked through your email provider at any time
