Transform email into collaborative workflows for productivity
Spike is an email-first productivity platform that converts traditional email into chat-like threaded conversations, built for teams and knowledge workers who want faster collaboration and reduced inbox noise. It combines unified email, collaborative notes and Tasks inside one app with a Freemium plan and paid Teams/Business tiers, making it suitable for small teams and professionals who need structured communication without replacing core tools.
Spike is an email-centric productivity app that reimagines email as chat-style conversations, combining messaging, collaborative notes, Tasks, and calendar in one unified client. Its primary capability is turning your inbox into real-time conversational threads while preserving SMTP/IMAP compatibility, which reduces context switching. Spike's key differentiator is its conversational email UI plus shared Notes and Tasks tightly integrated into the same workspace, aimed at remote teams, freelancers, and small businesses. Spike offers a free tier with basic mail and chat features and paid Team/Business plans for advanced collaboration and admin controls, making it accessible for most users.
Spike launched as a consumer and team-focused email app that reframes email into conversational threads to speed communication and reduce inbox clutter. Founded to compete with traditional email clients, Spike positions itself as a productivity layer over existing email accounts by connecting via standard IMAP/SMTP or OAuth for Gmail and Outlook. Its core value proposition is to let teams collaborate directly inside email threads while maintaining compatibility with the broader email ecosystem, preventing lock-in yet improving day-to-day workflow efficiency.
Spike's feature set focuses on three integrated areas: conversational email, collaborative Notes, and Tasks. Conversational email replaces message lists with chat-style threads that group replies and attachments; it still sends and receives standard email so messages reach recipients outside Spike. Notes offers real-time collaborative documents that can be linked into chats or shared with teams for meeting agendas or project specs.
Tasks is a built-in to-do manager where you can assign items, set due dates, and surface tasks inside conversations. Additional capabilities include integrated calendar views, email snooze and follow-up reminders, message scheduling, priority inbox, and shared team inboxes for support or sales. Pricing starts with a Free plan that supports one email account, conversational mail, basic Notes and Tasks, and up to a limited number of shared team members.
Paid plans expand admin controls, unlimited connected accounts, shared mailboxes, and extended collaboration features. As of the latest pricing, Spike's Individual (Pro) plan is paid per user monthly and unlocks multiple accounts, priorities, and search; Team or Business plans add centralized billing, team admin tools, and shared inboxes at higher per-user rates, while Enterprise/Custom offers single sign-on and dedicated support. Exact monthly prices and seat minimums vary by region and sales channel; Spike also offers annual billing discounts.
Spike is used by freelancers converting email into quick client chats, small sales teams managing outreach from a shared inbox, and product teams coordinating specs via Notes linked to messages. Example users include a Customer Support Lead using shared inboxes to reduce first-response times, and a Product Manager using Notes and Tasks to turn meeting email into assignable work. Compared to a traditional email client, Spike trades classic folder-based workflows for conversation-first collaboration; compared with Slack it keeps SMTP/IMAP compatibility so external recipients still receive standard email.
Three capabilities that set Spike apart from its nearest competitors.

You save: Potential savings depend on adoption and review time
Caveat: ROI depends on adoption, usage limits, plan cost, output quality and whether the workflow repeats often.
The numbers that matter — context limits, quotas, and what the tool actually supports.
What you actually get — a representative prompt and response.
Choose Spike over Front if you prioritize chat-style conversational email and integrated Notes rather than complex shared-inbox routing rules.
