HEY Email Alternatives That Keep Your Gmail Address

The reason people admire HEY isn't the app so much as the shape of the workflow: a Screener that catches every first-time sender before they can reach you, an Imbox that only shows the people you've said yes to, and separate stacks for newsletters (The Feed) and receipts (Paper Trail) so the mail that isn't a conversation stops behaving like one. It's a real editorial policy built into an email client.

The catch is the address. Adopting HEY natively means a new hey.com or hey-domain address, a new provider, and moving anyone who already emails you at your Gmail address. This post is for the reader who wants the workflow without any of that — Gmail keeps holding the mail, and something in front of it does the screening.

Our pick for most people is AI Emaily, because it treats sender approval, newsletter separation and receipt quarantine as the same triage problem and does it on your existing Gmail, Outlook or IMAP account under an approval-first agent rather than an autopilot. Below that: seven more options, ranked honestly, with one concession we'd make by name.

What you're actually trying to replicate#

Before ranking anything, name the four pieces of HEY's workflow — because different tools replicate different pieces, and a bad match here is where roundups usually go wrong.

• Screener — every first-time sender is held. You say yes once (they reach your Imbox forever after) or no once (they never bother you again). Nothing new ever lands in the important pile unapproved.
• Imbox — the small, focused inbox for the humans you approved. It behaves like a to-do list of conversations, not a firehose.
• The Feed — newsletters and long-form reading pulled into a scrollable, magazine-like view instead of counting toward the inbox.
• Paper Trail — receipts, order confirmations and account notifications sent to a searchable archive that never nags.

The trick to picking well is knowing which of the four matters most to you. If it's the Screener, you want a tool that actually holds unapproved senders somewhere separate rather than a folder you have to remember to check. If it's The Feed and Paper Trail, you want reliable newsletter and receipt classification, and a place for them that doesn't feel like a punishment. If it's the whole editorial policy, you want one tool that owns all four pieces — which is a shorter list than the AI-email category as a whole.

How we compared#

Every tool below connects to your existing Gmail address through Google's OAuth API or standard IMAP. Nothing gets migrated. We ranked on four dimensions the usual 'HEY alternatives' listicles skip:

• Client vs overlay vs filter — does it replace Gmail's interface, sit inside it, or run server-side and stay invisible to whichever app you use?
• How many of HEY's four pieces it actually replicates — some do the Screener well and ignore newsletters; some do newsletters well and never screen a sender.
• What happens if you stop paying — a usable free tier, a time-limited trial, or nothing at all.
• Provider reach — Gmail-only, or Gmail plus Outlook and IMAP under one triage layer.

HEY-workflow alternatives at a glance#

Type tells you where the tool sits. Screener and Feed columns tell you whether the HEY concept is genuinely built in, faked with a label, or absent.

The tools, ranked#

Each entry covers what the tool actually replaces from HEY's workflow, how it connects to your Gmail address, and the one caveat we'd want a friend to know before signing up.

1. AI Emaily — the pick, and why#

We build AI Emaily, so read this entry as advocacy, not a neutral review — that's true nowhere else on this list. It connects to your existing Gmail address through Google's OAuth API, plus Outlook and any IMAP mailbox, so a Gmail address, a work Outlook account and a personal IMAP inbox appear as one triage surface instead of three separate apps trying to do the same job.

It replicates HEY's four pieces in a way most tools don't attempt as a set. The cold-email filter holds first-contact senders in a separate queue instead of letting them touch your main inbox — the closest thing on Gmail to HEY's Screener, minus the requirement to change addresses. Auto-categorisation splits newsletters and receipts into their own streams, giving you a functional Feed and Paper Trail against Gmail without inventing folders you'll never remember to open. Rules and the Context Brain learn how you triage; the agent proposes, you approve.

Autonomy is the safety story that matters here. Copilot mode drafts replies and files mail into the right label, but nothing sends without your approval, every autonomous action lands in an audit trail, and voice comes from a Personal Context brain you set yourself plus per-client profiles — never a model trained on your sent mail. Autopilot exists for narrower, gated actions with the same undo and audit underneath.

Where we ship: a real downloadable app for Mac (Apple Silicon only, built on Electron so features land the same day as web) and Windows, a native app on the App Store for iPhone and iPad, and a PWA on Android. No native Android app yet, no Linux build, and against a native Swift client like Mimestream the Electron shell will not match on memory footprint or a fully local offline archive. Both halves of that are true; stating both is the point.

2. Shortwave#

Shortwave is a Gmail-native client built by a team of ex-Google engineers. It leans on Gmail's own category system — Primary, Social, Promotions, Updates — surfaces them as separate feeds, and layers an AI summariser and search on top. That gets you a rough equivalent of The Feed and Paper Trail with less setup than most tools.

It's weaker on the Screener piece. First-time senders can be bundled into a lower-priority feed, but there is no explicit per-sender approve-or-block prompt the way HEY makes the choice unavoidable. If the Screener is your favourite HEY feature specifically, this replicates about half of it.

As of our July 2026 check against shortwave.com/pricing, there is no permanent free plan — a trial then Business, Premier or Max, seat-priced, scaling on AI usage quota. Some review sites still describe a free tier; the vendor's live page didn't show one, so verify before you plan around it. Gmail-only, no Outlook or IMAP.

3. Superhuman Mail#

Superhuman Mail is the client half of what's now the Superhuman Suite — Grammarly acquired the email client in July 2025 and renamed the parent company Superhuman in October 2025, so the name covers two different things. This entry is about the mail client, not the writing-assistant bundle.

It gives you Split Inbox — rule-driven columns you configure by sender or label — plus an Important detection layer. You can absolutely build a HEY-shaped workflow inside it, but the pieces are opt-in rather than the default posture. The Screener specifically is not built in as a first-time-sender approval loop; you would build the rules yourself.

Connects to Gmail or Outlook by OAuth, no IMAP. Paid only, with a trial that's referral-based in most cases and Starter, Business plus custom Enterprise tiers. Check superhuman.com directly — the trial mechanics have changed more than once.

4. SaneBox — where we concede#

SaneBox has done server-side sender screening on Gmail longer than any tool on this list, and it earns a concession by name: if the single thing you want is HEY's Screener behaviour on your existing Gmail account, and you want it to keep working no matter which client or phone app you switch to next year, SaneBox is the stronger, more durable choice than we are. It runs inside your Gmail account itself via IMAP, not inside an app, so the triage layer follows the mail rather than the interface.

The workflow: unfamiliar and low-priority senders drop into a @SaneLater folder; newsletters into @SaneNews; receipts into @SaneReceipts. A one-time move-to-folder gesture trains the classifier per sender, which is the same shape as HEY's yes-once, no-once decision, done without a purpose-built UI.

What it doesn't give you is a native inbox interface — Gmail is still your reader, so if part of what you dislike about Gmail is the interface itself, SaneBox alone won't fix that. It is a filter, not a client. Packaging is a two-week free trial, then per-mailbox tiers you can check on sanebox.com. Ours is the better fit if you also want drafting, unified accounts and an agent; theirs is the better fit if you specifically want a screener that outlives whichever client you happen to be using this year.

5. Fyxer#

Fyxer is an overlay, not a client — it installs into Gmail or Outlook and adds triage labels, drafted replies and meeting notes inside the interface you already have. You never leave Gmail's own inbox; Fyxer annotates it. That is a genuinely different answer to 'I want more from Gmail without switching apps.'

For the HEY workflow specifically, it does newsletter and low-priority separation via auto-labels, and drafts replies in your voice. What it doesn't do is a formal Screener — new senders aren't held for per-sender approval the way HEY holds them; they are labelled after the fact, which is a softer version of the same idea.

Packaging is paid with a trial on request, per-seat. Check fyxer.com for current tiers. Right answer if the interface is fine and you want it smarter; wrong answer if you want a strict yes-or-no gate on every new sender.

6. Inbox Zero (open source)#

Inbox Zero is an open-source AI email assistant that connects to Gmail and adds sender approval, bulk unsubscribe, cold-email blocking and reply-tracker rules. It is the entry on this list closest in spirit to HEY's Screener because the sender-approval flow is one of its named features rather than a side effect of a bundle view.

It is Gmail-only, and you have two ways to run it: self-host the open-source repo for zero recurring cost against your own compute, or use the hosted plans on getinboxzero.com. Verify the current hosted tiers on the vendor's own page; open-source project packaging changes faster than review sites track.

Good match if you want a Screener-shaped tool you can inspect the code of, and you are already comfortable with a self-hosted deployment or willing to pay for the hosted version. Not the pick if you also need Outlook or IMAP under the same triage layer.

7. Spark Mail#

Spark connects to Gmail, Outlook, iCloud, Yahoo and IMAP by OAuth or app password, and its Smart Inbox groups mail into People, Notifications, Newsletters and Pinned automatically. That covers The Feed and Paper Trail reasonably well, without you having to configure much.

It does not hold first-time senders in a Screener-style approval queue. New humans go into People; you can archive or block after the fact, which is a lighter-touch version of HEY's gate. Packaging is free-tier-first, then Plus and Pro per-seat tiers plus a custom Enterprise plan. Check spark.email for current seat costs; they moved twice in the last year. Choose it for the familiar three-pane layout with light categorisation, not for a strict Screener.

8. Cora#

Cora sits on top of Gmail or Outlook and produces a twice-daily digest of the mail you'd otherwise skim past — a rough analogue of pulling low-value threads out of your Imbox so only the ones worth reading show up in the main view. It is the entry here most specifically shaped like The Feed, in that its output is a scheduled summary rather than a live sort.

It is not a Screener. New senders are not held for approval; they are summarised alongside everyone else, which is the opposite of HEY's gate. Packaging is paid with a trial on request; check cora.computer directly. Right answer if the piece of HEY you miss most is the low-noise digest of everything that doesn't demand a reply; wrong answer if what you actually want is the per-sender yes-or-no.

How to choose for your situation#

The right pick depends on which piece of HEY you actually miss, not on which tool lists the most features. A few honest matches:

• You miss the whole editorial policy — Screener, Imbox, Feed and Paper Trail as one system — and you also run Outlook or IMAP alongside Gmail: AI Emaily, so one triage layer covers all four pieces across all three account types.
• You care about the Screener above everything else, and you want it to keep working no matter which client you use next year: SaneBox, by our own admission above. It is a filter, not an app, and it will outlive the interface you're using today.
• You live entirely in Gmail and mainly want The Feed and Paper Trail with less setup: Shortwave, which surfaces Gmail's own category feeds with an AI summariser on top.
• You want the Screener specifically, in open source, on Gmail: Inbox Zero — either self-hosted or on the vendor's hosted plan.
• You like Gmail's interface and want triage annotations added inside it: Fyxer or a similar overlay, not a client.
• You want a scheduled digest of the noise so only real conversations stay in the main view: Cora.
• You want the fastest keyboard-first triage and are happy building the rules yourself: Superhuman Mail, accepting the paid-only and Gmail-or-Outlook-only limits.
• You want a familiar three-pane client with a Smart Inbox and a free tier: Spark Mail.

Whichever you pick, the underlying move is the same: connect the new tool to your existing Gmail address, keep Gmail's own web interface open as a fallback for as long as you want, and disconnect cleanly if it doesn't work out. Nothing on this list requires Google Takeout or a provider change — that is a different, harder problem this post isn't about.
