Google Inbox Alternatives in 2026
Last updated: September 13, 2026
Inbox by Gmail shut down on April 2, 2019, and people are still looking for something that replaces it. Gmail kept a few of its ideas and dropped the rest, and no single tool has recreated the whole thing. Here's what actually survived, and which of the alternatives get closest to what you used to have.
We make Email Elysium, a Chrome extension that adds nested folders to Gmail, so we have a stake in this. It isn't an Inbox clone, and we say where it fits and where it doesn't further down.
What Inbox actually did
Inbox grouped related mail into Bundles (Purchases, Travel, Finance, and others you could define yourself), let you Snooze a message until a chosen time, Pin messages you needed to come back to, and surfaced Highlights such as flight details or event info pulled out of the email body. It also shipped Nudges, reminders to reply to or follow up on a message, and an early version of Smart Reply.
Which of it Gmail kept
| Inbox feature | In Gmail today? |
|---|---|
| Snooze | Yes, hover a message and click the clock icon |
| Nudges | Yes, "Suggested" prompts to reply or follow up |
| Smart Reply / Smart Compose | Yes, expanded well beyond Inbox's version |
| Bundles | Not directly. The closest equivalent is the five fixed inbox categories (Primary, Social, Promotions, Updates, Forums), which sort by type, not by a rule you write |
| Pins | No native equivalent; starring is the nearest analog, but it doesn't group pinned items together the way Inbox did |
| Highlights | Partially, in specific cases like flight and hotel confirmations, but not as a general feature |
So the gap people feel is mostly bundles and pins: a flexible way to group mail by topic and pull the important ones aside. That gap is what most of the alternatives below are trying to fill.
The alternatives, by what they recreate
Simplify Gmail: the closest thing to Inbox's actual design
Simplify Gmail is a free Chrome extension built by Michael Leggett, who co-founded Inbox and was Gmail's lead designer from 2008 to 2012. After Inbox shut down, he built Simplify to bring a calmer look and bundled conversations back to Gmail itself, and it's still maintained. It groups same-label conversations into single collapsible rows, which is the closest thing here to Inbox's bundling, and it ships with a set of pre-built saved searches similar to Inbox's Bundles. It's a restyle of Gmail's own interface, not a separate app, and it's free.
Shortwave: a full client built by ex-Google engineers
Shortwave is a standalone email client for Gmail and Google Workspace, built by former Google engineers, with the same instinct: bundle related messages, surface what matters, and let AI handle the busywork. It has AI filters you write in plain English, AI-drafted replies, and a genuinely different interface from Gmail's. The catch is pricing: Shortwave no longer has a free tier, and it starts at $30 per seat per month after a 14-day trial.
Spark: a full client with a real free plan
Spark is another standalone client with a Smart Inbox, snooze, and scheduled send on a genuinely free plan across desktop and mobile. Its AI features (drafting, meeting notes) sit behind paid tiers starting around $10 per month. If you want a full Inbox-style app without committing to Shortwave's price, this is the more approachable option to try first.
Where Email Elysium fits, and where it doesn't
Email Elysium isn't a bundling tool and doesn't try to be. It adds a real nested folder tree and auto-sort rules directly inside Gmail's own interface, with no separate client to switch to and no OAuth permission granted at all.

FAQ
When did Google Inbox shut down?
April 2, 2019, after Google announced the retirement the previous September. It ran for a little over four years.
Did Gmail get any of Inbox's features?
Yes. Snooze, Nudges, and Smart Reply all moved into Gmail. Bundles, Pins, and Highlights did not; Gmail's fixed inbox categories are the closest equivalent to Bundles, but they group by type rather than by a rule you write.
What is the closest replacement for Google Inbox?
Simplify Gmail, built by Inbox's co-founder specifically to bring Inbox-style bundling and a calmer interface back to Gmail. It's a free Chrome extension, not a full replacement client.
Is there a paid alternative that fully replaces Google Inbox?
Shortwave is the closest full client: bundling, AI priority surfacing, and AI drafting, built by former Google engineers. It starts at $30 per seat per month with no free tier. Spark is a cheaper option with a genuine free plan, though its AI features are paid.
Does Email Elysium replace Google Inbox?
Not fully. It adds real nested folders and auto-sort rules to Gmail, which is closer to filing than to Inbox's bundle-and-snooze workflow. Simplify Gmail or Shortwave are closer matches if bundling is what you miss most.
