Missive

Are you double sending emails? Not knowing who's responding to what, or whether they've responded at all? Losing the thread when the person who owns it is out? What if your business could manage all your email accounts, including its shared inboxes like support@, sales@, info@, and accounting@, along with SMS, WhatsApp, Messenger, and Instagram—all in one place? Missive is inbox collaboration for teams that run on email. Every conversation gets an owner, so nobody replies twice and nothing sits unread for a week. Teammates discuss a thread in private comments right beside it instead of forwarding it around, and when someone's away, whoever picks it up gets the full history. Missive's AI assistant works inside the inbox. It reads a thread and drafts a reply in your voice, searches your email, contacts and calendar, and reads attachments. Through MCP it pulls context from tools like ClickUp, Todoist and Stripe—and the reverse, letting Claude, ChatGPT or Cursor act on your conversations, contacts and drafts from outside Missive. Bring your own Claude, OpenAI or Gemini key, or use Missive AI credits. You approve before anything sends. Used by over 6500 businesses, including accounting firms, manufacturers, property management companies, travel agencies, legal practices, and logistics teams. -- Key features • Team Inboxes: Shared addresses the whole team works from, with assignment so every conversation has a clear owner and coverage when someone's out. • Internal comments and @mentions: Discuss a thread in a private sidebar next to the actual email. The customer never sees it. • AI assistant: Drafts replies in your voice, searches your inbox, contacts and calendar, and reads attachments. Labels, events and sends happen only after you approve. • MCP in both directions: Missive AI connects out to tools like ClickUp, Todoist and Stripe, and Missive's MCP server lets Claude, ChatGPT or Cursor work on your inbox from outside. • Automated Workflows: Create customizable rules to automate repetitive tasks and use AI to get even more efficiency. Popular use cases include auto-categorization of emails, auto-follow-up emails, automatic forwarding of receipts, and out-of-office auto-responses. • Canned responses: Save time with pre-written replies to customer inquiries, sales pitches, or to include that PDF you always need to attach when signing up a new client. • Integrations: Pipedrive, HubSpot, Shopify, Airtable, ClickUp, Asana, Dialpad, Twilio, Aircall, Zapier, and a REST API for building your own.

Front

Front is an AI customer operations platform built for the complexity of B2B customer relationships. It connects customer conversations, teams, AI agents, and tools on one platform so organizations can coordinate customer work across support, operations, customer success, account management, and other customer-facing teams. Front brings conversations across email, SMS, WhatsApp, live chat, social channels, and other connected channels into a shared workspace. Teams can assign clear ownership, collaborate directly alongside customer conversations, automate routing and workflows, coordinate handoffs across teams, and access relevant customer context without moving work across disconnected inboxes and tools. This gives teams greater visibility into the work behind each customer interaction while helping them respond accurately and efficiently. Front is particularly suited to complex B2B customer operations, where resolving a customer request may require multiple people, teams, systems, and steps. Rather than treating every interaction as an isolated support ticket, Front keeps the conversation connected to the context, ownership, and workflows required to move the customer's request forward. Integrations and APIs connect Front with the systems teams already use, helping relevant customer and operational information stay available where the work happens. AI works within the same workflows as your team. Autopilot, Front's omnichannel AI agent, runs complex customer work from end to end, and teams can build custom Autopilot agents for their brands, teams, and processes. Customers can also bring in external AI agents to join Front as teammates and set their scope and permissions. Copilot gives teams the context, the draft, and the prep for every customer conversation. Organizations decide where AI agents take on work, where human judgment is needed, and how both operate with shared context and clear guardrails. Front combines customer conversations with workflow automation, collaboration, analytics, integrations, and AI so teams can manage complex customer work without losing visibility or control as they scale. More than 9,300 businesses, including Uber Freight, Stripe, and OpenAI use Front to coordinate customer operations and keep teams, tools, and customer conversations in sync.
