## 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

## Spike

Spike reimagines email as a chat-style feed instead of a stack of threads. You can connect an existing Gmail, Microsoft, or other account and use Spike as your daily client, or create a new business email on a custom domain hosted by Spike. Conversations group by person, attachments and files appear in one place, and a unified inbox pulls every account into a single view so you stop jumping between apps.

AI is woven through the experience. Smart sorting surfaces important messages first, AI summaries give instant snapshots of unread mail and long threads, and contextual drafting helps you compose quick replies or brainstorm with AI in your own voice. Built-in translation handles messages you receive or write, and natural-language search helps you find emails and files fast.

For teams, Spike adds shared inboxes for customer email, channels and groups for discussion, collaborative docs and notes, tasks that live inside the inbox, and one-click audio or video meetings. Non-Spike recipients still receive a normal email, so external contacts need no special setup. A free tier is available alongside paid plans, and the company also promotes iGPT, an email intelligence API that powers AI agents and automations with email context.

**Pricing & Plans:** Offers a free plan plus paid tiers; exact pricing and per-seat limits for teams change over time, so check the official pricing page for current numbers.

- **AI summaries and smart sorting:** AI snapshots unread mail and long conversations so you can catch up in seconds, while priority inbox surfaces the messages that matter first.
- **Context-aware AI drafting:** Draft quick replies, contextual responses, and brainstormed messages with AI assistance directly inside the composer.
- **Conversational email and unified inbox:** Threads are grouped by person like a messenger app, and every connected account lands in one inbox with file management and powerful search.
- **Team collaboration tools:** Shared inboxes, channels and groups, collaborative docs and notes, tasks, and one-click audio and video meetings all live inside your mail workspace.
- **Works with your existing email:** Use Spike with an existing Gmail or Microsoft account, or create a business email on a custom domain with Spike's email hosting.

**Strengths:** Conversational, chat-like interface makes long email threads easier to follow; AI summaries and drafting cut time spent catching up and replying; Consolidates mail, chat, docs, tasks, and meetings into one workspace; External recipients still get standard email, so no one else has to switch

**Limitations:** Best experience requires adopting Spike as your primary mail client; Advanced team features sit behind paid tiers, so costs scale with seats; Feature breadth can feel overwhelming for users who only want a simple inbox
