Spike
AI-first email app that turns your inbox into a chat-style hub for email, docs, tasks, and calls
Pick Spike if your team lives in email and you want shared inboxes, docs, tasks, and calls in the same window — at $4 per member per month billed annually on Team, it's cheaper than stitching together a mail client plus a per-seat chat tool. The AI priority sorting and thread summaries are the parts that actually save time day to day. Two things to weigh: SAML-SSO and video call recording are still marked "SOON" on the Business tier, so security-led organisations shouldn't count on them yet, and the free Starter tier stops at 3 members and 1 teamspace, which you'll outgrow quickly. If you need a mature connector ecosystem or on-premises mail, look at Google Workspace with Slack instead.

Skip Spike if you need SAML-SSO available today or on-premises mail storage, or if you rely on deep native connectors into other business systems.
Choosing month-to-month instead of annual billing raises Team from $4 to $5 per member per month and Business from $8 to $10 per member per month.
Team at $4 per member per month billed annually ($5 month-to-month) undercuts most per-seat collaboration suites, and the free Starter tier at up to 3 members is a genuine entry point for a solo founder or a two-person consultancy. Business at $8 per member per month billed annually ($10 monthly) targets teams that need 1 TB per member and 500 MB uploads. Compare against paying separately for a mail client plus a chat tool per seat.

About Spike
Spike runs your existing email — Gmail, Microsoft, or other accounts — inside an interface that reads like a messaging app: threads collapse by person, and outside recipients still get a normal-looking email. Alongside the unified inbox you get team chat through Groups and Channels, collaborative notes and docs, tasks, a calendar, shared inboxes for customer email, and one-click audio and video calls, so most of the day happens without leaving the app. Spike AI sits on top of that: it sorts incoming mail by priority, summarizes unread threads, and drafts replies with conversational context. You can either upgrade an existing address or create a business address on a custom domain inside a teamspace, where every member gets a @spike.team or custom-domain mailbox. Apps exist for Windows, Mac, iOS, and Android plus a web client. It suits founders, consultants, freelancers, sales and support teams, and remote teams that want one hub instead of email plus a separate chat tool. The free Starter tier covers up to 3 members, 1 teamspace, 60 days of search history, and 15 GB of storage per member; Team adds a free custom domain, unlimited search history, 100 GB per member, and Shared Inbox; Business adds 1 TB per member, 500 MB file uploads, and VIP support.
Behind the Verdict
Spike's real bet is that the inbox is already the most-used collaboration surface, so it turns email into chat rather than asking you to move conversations elsewhere. Practically, that means a unified inbox across your accounts, conversations grouped by person, and team features — Groups, Channels, Shared Inbox, collaborative docs, tasks, calendar, video meetings — layered on top. Non-Spike recipients still receive a conventional email, which removes the usual network-effect objection.\n\nThe AI layer is narrower than the marketing implies but useful: priority sorting that pushes important mail up, summaries of unread threads so you can catch up on a long chain in seconds, and drafting help that responds with context from the thread. It is an assistant inside the inbox, not an autonomous agent.\n\nStrengths: consolidating multiple accounts into one place; shared inboxes that let a support or sales team work the same customer thread; docs and tasks that live next to the conversation instead of in a separate tab; and pricing that starts free for up to 3 members and sits at $4 per member per month billed annually for Team ($5 billed monthly) and $8 per member per month billed annually for Business ($10 billed monthly). App coverage across Windows, Mac, iOS, Android, and web means most people can work where they already do.\n\nWeaknesses to plan around: the free tier's 60-day search history and 3-member cap, and the 15 GB per member storage ceiling, bite quickly for anyone with years of mail. Business-tier SAML-SSO and video call recording are still labelled SOON, so identity and compliance teams can't standardise on them today. Spike is cloud-hosted, storing mail on its servers, which rules it out where data residency is a hard requirement, and there's no on-premises option. Teams that treat email as a read-only archive with heavy archiving and eDiscovery needs are better served by a conventional provider.\n\nWhere it fits best: a founder or consultant juggling three client accounts, a support pod that needs a shared inbox without buying a helpdesk, or a remote team under a few dozen people that wants to drop one app from its stack. Where it doesn't: regulated enterprises needing SSO today, and anyone whose workflow depends on deep connectors into other business systems.

Real-world workflow fit
Concrete scenarios for the personas Spike actually fits — and what changes day-one when you adopt it.
Connect Gmail and two client Microsoft accounts to the unified inbox, let the AI Priority Inbox push urgent client mail to the top, and use AI drafting to answer routine questions in the thread.
Outcome: One inbox instead of three tabs, with replies sent from the free Starter tier in minutes rather than a longer setup.
Create a teamspace with a free custom domain on Team, route inbound support mail into a Shared Inbox so two agents can work the same customer thread, and track follow-ups as tasks inside the conversation.
Outcome: Support email stops living in one person's mailbox and becomes a shared queue with visible ownership.
Use Channels for standing team discussions and Groups for client or partner threads, drop notes and docs next to the conversation, and start a one-click call when a thread needs a live decision.
Outcome: Team chat, documents, and calls happen inside the inbox rather than in a separate app, cutting the number of tools to check daily.
Use Cases
- Consolidate Gmail, Microsoft, and other accounts into a single unified inbox
- Run a support or sales shared inbox so several people work the same customer thread
- Draft replies and summarize long threads with AI instead of reading everything
- Hold team calls and share docs without leaving the inbox
- Host a business email domain for a small team with a free custom domain on Team
- Track tasks and deadlines from inside email threads
- Keep client conversations in Groups and Channels instead of a separate chat app
Models Under the Hood
as of 2026-09-23
Limitations
- The free Starter tier caps you at 3 members, 1 teamspace, 60 days of search history, and 15 GB of storage per member, so it is a trial-sized tier rather than a long-term home.
- Team and Business prices of $4 and $8 per member per month require annual billing; month-to-month runs $5 and $10 per member.
- Business-tier video call recording and SAML-SSO across devices are listed as SOON on the pricing page, so identity and compliance teams cannot standardise on them yet.
- Spike is cloud-hosted and stores your mail on its servers with no on-premises deployment, which may conflict with data-residency rules.
- The published pricing page does not document third-party connectors, so plan on treating Spike as the place work happens rather than a hub that pipes into other systems.

Plans compared
For each published Spike tier: who it actually fits, and what it adds vs. the previous tier. Cross-reference the cost calculator above for projected annual outlay.
Starter
$0/mo
Ideal for
A solo founder or a team of up to 3 people testing whether a chat-style inbox fits how they work.
What this tier adds
Free entry point: up to 3 members, 1 teamspace, free @spike.team addresses, 60 days of search history, 15 GB per member, and Spike AI.
Team
$4/member/mo billed annually
Ideal for
A growing team of roughly 4 to 30 people that wants a shared inbox and its own domain without buying a separate chat tool.
What this tier adds
Adds a free custom email domain on a yearly plan, unlimited search history, 100 GB per member, and Shared Inbox, at $4 per member per month billed annually.
Business
$8/member/mo billed annually
Ideal for
A larger team or business handling heavy attachments and wanting priority vendor support.
What this tier adds
Adds 1 TB storage per member, 500 MB file uploads, and VIP support — with video call recording and SAML-SSO listed as SOON — at $8 per member per month billed annually.
Where the pricing makes sense
The company stage and team size where Spike's pricing actually pencils out — and where peers do it cheaper.
Team at $4 per member per month billed annually ($5 month-to-month) undercuts most per-seat collaboration suites, and the free Starter tier at up to 3 members is a genuine entry point for a solo founder or a two-person consultancy. Business at $8 per member per month billed annually ($10 monthly) targets teams that need 1 TB per member and 500 MB uploads. Compare against paying separately for a mail client plus a chat tool per seat.
Setup time & first value
How long it actually takes to get something useful out of Spike — broken out by persona, not the marketing-page minute.
If you already have Gmail or Microsoft mail, connecting an account and reaching a working unified inbox takes minutes. Adding a teamspace with a free custom domain on Team takes a little longer because domain verification is involved. Because SAML-SSO is still labelled SOON, larger teams should plan on manual member provisioning rather than an identity-provider rollout.
Switching to or from Spike
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From Gmail: upgrade your existing Google account inside Spike and your mail and threads appear in the conversational inbox.
- →From Microsoft Outlook or Microsoft 365: connect the account the same way and manage it in the unified inbox alongside other addresses.
- →From a standalone mail client: connect your existing IMAP-style account and keep the same address while changing the interface.
- →From a separate team chat tool: move standing discussions into Channels and client threads into Groups so the conversation sits next to the email it relates to.
- ↗To Google Workspace: keep your custom domain, repoint MX records, and export mail from Spike's servers to Google's.
- ↗To Microsoft 365: the same domain repointing and mailbox export path applies when moving back to a conventional provider.
- ↗To a conventional client with a separate chat tool: extract mail and re-establish team chat in the chat product, accepting that docs and tasks leave the inbox.
