Spike

Spike is an email client that presents messages as chat-like conversations while recipients still receive normal email. It can connect existing Gmail, Microsoft and other accounts in one unified inbox with a calendar, or provide business email for a team. Built-in AI sorts the inbox, summarizes conversations and drafts replies with context, and other tools include priority inbox, snooze, scheduled sending, bulk unsubscribe and translation. Spike also adds team channels and groups, collaborative notes, docs and tasks, and secure audio and video calls, and people outside Spike can still join conversations and documents.

Spike suits individuals and small teams who want email, chat and light project work in one app across mobile, desktop and web. Connecting a mailbox gives the app broad access to email data, so teams should review the privacy policy and admin settings first. Nothing was tested for this listing.

The pricing page lists Email App plans at $6 per user per month for Pro and $12 per user per month for Ultimate, both billed annually, with yearly billing saving 25%. Pro supports up to 3 email addresses and 5 GB of storage, while Ultimate removes the address limit and adds 20 GB. Teamspace plans are priced separately.
