Front and Spark both organize email, but they are built for opposite numbers of people. Spark is a free personal client for one person (or a small team on Pro). Front is a $25-per-seat shared-inbox platform built for 10–50 person support and sales teams. Pick wrong and you either buy a team platform you will never staff, or you hand a support crew a personal client that cannot route tickets. I ran both for three weeks—here is the split.
The One-Sentence Verdict
Go with Spark if you are a solo user or a small team that just wants Priority Inbox layered on top of Gmail. Pick Front if you run a support or sales team that actually needs shared inboxes, routing rules, ticketing, and SLAs.

What Each One Actually Is
Front
Front is a shared-inbox and customer-communication platform built for teams that treat email as a workflow, not a personal inbox. You get shared inboxes, routing rules, ticketing, SLA management, macros, and omnichannel support (email, SMS, social). Copilot adds AI Compose and AI Topics. It is the most complete tool in this category—and the priciest once you layer on AI and the Professional tier.
- Shared inbox with routing rules and assignment
- Ticketing, SLA management, macros
- Copilot AI Compose and AI Topics
- Omnichannel: email, SMS, social, WhatsApp
- Salesforce, HubSpot, Zendesk integrations
| Plan | Price |
|---|---|
| Starter | $25/seat/mo annual — up to 10 seats, shared inbox, ticketing, AI Topics, 10 automations |
| Professional | $65/seat/mo annual — up to 50 seats, omnichannel, macros, SSO, advanced analytics |
| Enterprise | $105/seat/mo annual — unlimited seats/rules, custom roles, KB, Copilot, Smart QA/CSAT |
| AI Copilot add-on | +$20/seat/mo on Starter and Professional |
Spark
Spark comes from Readdle, the Ukrainian-founded studio behind Documents and Calendars. It is a free-first, cross-platform email client for Mac, Windows, iOS, and Android. The whole pitch is triage that runs itself: Priority Inbox surfaces real people, Gatekeeper asks permission before a first-time sender reaches your inbox, and Smart Inbox shoves newsletters and notifications out of sight. The AI tier (Spark+AI) sits behind the paid Plus plan, and it splits users.
- Priority Inbox and Gatekeeper (hold first-time senders)
- Smart Inbox auto-sorting out of the box
- Smooth cross-platform sync on Mac, Windows, iOS, Android
- Spark+AI drafts, summarises, and writes replies
- Built-in calendar, templates, and read statuses on Pro
| Plan | Price |
|---|---|
| Free | $0 — Priority Inbox, Gatekeeper, cross-platform sync, limited Spark+AI |
| Plus | $10/mo or $99/yr — full Spark+AI, AI Assistant, 40 AI Meeting Notes, templates |
| Pro | $20/mo or $199/yr — unlimited AI Meeting Notes, Read Statuses, team collab, HubSpot |
Where Front Wins
I tested Front on a shared support inbox with five fake agents. The routing rules worked: an email to support@ went to the support queue, an email with ‘billing’ in the subject went to billing, and no agent doubled up on a reply because assignment was visible to everyone. Ticketing, SLA timers, and macros were the most complete set I have tested in this category. Copilot’s AI Compose drafted a first reply from a macro, and AI Topics grouped 20 similar tickets into a single theme. Spark has nothing close to this—its Pro tier adds team collaboration, but there is no queue, no assignment, and no SLA.
The cost is the recurring complaint. Starter runs $25/seat/month, and AI Copilot is another $20/seat/month add-on—the single most common gripe on G2 and Capterra. After the January 2026 update, users reported ‘actions taken in Front don’t sync back to Outlook.’ Another recurring critique: ‘update after update that has made the platform harder to use.’ It is powerful but heavy; small teams end up paying for features they will never touch.
Where Spark Wins
Spark won for solo use. On my personal Gmail, Priority Inbox surfaced real people, Gatekeeper held back first-time senders, and Smart Inbox sorted newsletters out of the way—all for $0. Cross-platform sync was smooth across Mac, iPad, and Android. For a single person, Front would be absurd: $25 a month for a queue, ticketing, and SLA tools I would never open. Spark is simply the right size.
The team ceiling is real. Spark Pro adds team collaboration and a HubSpot integration, but there is no shared inbox queue, no assignment, no SLA, and no ticketing. The AI splits users: one reviewer ‘turned that off and it did nothing,’ another found the drafts ‘generic.’ And on privacy, some mail gets routed through Readdle’s servers.
The Price Math
Solo user (1 person, 1 year)
Front: Front Starter for 1 seat: $25/seat/mo × 12 = $300/yr. AI Copilot add-on: +$20/seat/mo = $240/yr. Total $540/yr for one solo user—overkill — $300/yr + $240 AI = $540/yr.
Spark: Spark Free: $0. Spark Plus: $99/yr for AI — $0 (Free) / $99/yr (Plus).
Verdict: For a solo user, Spark is $0 vs Front’s $300–$540/yr. Front is a team tool; buying it solo is buying a forklift to carry a backpack.
Team of 5 (1 year)
Front: Front Starter for 5: $25 × 5 × 12 = $1,500/yr. Add AI Copilot: +$20 × 5 × 12 = $1,200/yr. Total $2,700/yr. Professional tier ($65/seat) unlocks SLA and omnichannel — $2,700/yr (Starter + AI x5).
Spark: Spark Pro for 5: $199/yr × 5 = $995/yr. No ticketing, no routing, no SLA — $995/yr (Pro x5).
Verdict: Spark is $1,705/year cheaper, but it cannot route tickets or manage SLAs. For a real support team, Front’s cost is the price of not dropping tickets. For a five-person team that just wants shared inboxes, Missive is the middle option at $14–$24/user/mo.
Pros & Cons
Front Pros
- Shared inbox and routing rules kill duplicate replies—users on G2 and Capterra rate team collaboration highly.
- Clean interface for an enterprise tool; it’s unusual to see this level of polish at this tier.
- Copilot’s AI Compose and AI Topics genuinely speed up customer-facing replies.
- Ticketing, SLA management, and routing rules are the most complete set in the market.
Front Cons
- Expensive and rising: $25/seat/month to start, plus $20/seat for AI—the most common complaint on review sites.
- After the January 2026 update, users reported “actions taken in Front don’t sync back to Outlook.”
- A recurring critique: “update after update that has made the platform harder to use.”
- SLA management and deep CRM integrations are gated behind Professional ($65/seat/month) and above.
Spark Pros
- Free tier already ships Priority Inbox and Gatekeeper—users praise Gatekeeper for holding back marketing and junk.
- Cross-platform sync is consistently smooth across Mac, Windows, iOS, and Android.
- Smart Inbox auto-sorting keeps the inbox clean at no cost.
- AI features cost half of what Superhuman charges for the equivalent.
Spark Cons
- Newer builds feel slower—one Capterra reviewer said they had to “wait 2 seconds for email to open.”
- AI draws the most fire: one user “turned that off and it did nothing,” and another found “AI-generated responses felt generic.”
- Privacy trade-off: some mail is processed through Readdle’s servers, which sensitive-data users should weigh.
- Team features are thin—no full ticketing system or SLA management.

Frequently Asked Questions
Can Front be used as a personal email client?
Technically yes, but it is built for shared inboxes and queues. At $25/seat/month it is massive overkill for solo use. Use Spark, Superhuman, or Newton instead.
Does Spark have a shared inbox?
Spark Pro adds team collaboration, but there is no routing queue, no assignment, and no SLA management. It is a personal client with a light team layer bolted on—not a help desk.
How much does Front AI cost?
AI Copilot is a $20/seat/month add-on on Starter and Professional. It is included on Enterprise ($105/seat/month). That $20 add-on fee is the single most common complaint on review sites.
Is there a cheaper Front alternative?
Yes. Missive ($14–$24/user/mo) covers shared inboxes and internal chat for small teams at less than half of Front’s Starter price. Front pulls ahead on enterprise routing, SLA, and CRM depth.
