Spike

Spike is an email and collaboration app that turns conventional email into a conversation view. Threads are grouped by person, much like a messaging app, while outside recipients still receive ordinary email. It works with existing Gmail, Microsoft and other accounts, or with a business email address and domain set up through Spike. The AI features are built into the inbox. Smart sorting puts important messages first, AI summaries condense unread mail and long conversations, and a writing assistant called Magic Message drafts messages and replies with context. Beyond email, Spike combines team channels and groups, shared inboxes, collaborative notes and docs, tasks, video and audio calls, file management, unified search, reminders and the ability to connect several accounts in one inbox. People outside Spike can take part in groups and shared documents. The vendor also offers an email intelligence API, called iGPT, for feeding email context to AI agents and automations. Teamspace pricing has three tiers. Starter is free for up to three members and includes 15 GB of storage, 60 days of search history and Spike AI. Team costs $4 per member per month billed annually, or $5 billed monthly, and adds a custom email domain, unlimited search history, 100 GB of storage and shared inbox. Business costs $8 per member per month billed annually, or $10 billed monthly, and adds 1 TB of storage, 500 MB file uploads and VIP support. Individual plans also include a free tier.
