Coming soon to Mac, Windows, Linux, iPhone, iPad and Android
Heron brings Gmail, Outlook, iCloud and every IMAP mailbox together in one calm, fast app. Add an account once and it shows up on all your devices.
Features
Everything you expect from a modern email client, with no ads and no noise.
All Inboxes
Personal, work, side projects: your messages land in “All Inboxes”, each tagged with its account’s color. Your Heron account remembers your mailboxes and settings and syncs them to every device.
Conversations
Replies in the same thread are grouped on a single line. Open the conversation: older messages fold away and the latest one is shown in full.
Snooze · Schedule · Undo
Snooze an email until tonight, tomorrow or the weekend and it comes back to the top of your inbox right on time. Schedule a send for Monday 9 AM. And if you hit Send too fast, “Undo” brings it back to the editor.
Search
Search every account at once and narrow it down with filters: sender, recipient, subject, attachments, unread, dates, folder or account. Power users can type from:, has:attachment or after: directly.
Compose
Rich formatting, per-account signatures, drag-and-drop attachments and recipients suggested from your conversations. Drafts save themselves and follow you to every device.
Privacy
No ads, no selling your data, no mining your messages for commercial purposes. Heron only does what you ask it to.
Read the privacy policyRemote images, often used to tell when you open an email, are blocked by default. Show them for one message, for a trusted sender, or always.
Mailbox passwords and tokens are encrypted with AES-256-GCM before they are stored. With Google and Microsoft, Heron never even sees your password.
Full message bodies and attachments are not kept: they are read from your mail server when you open them.
Check SPF, DKIM and DMARC, follow a message from server to server and spot a suspicious sender.
Delete your account from the settings and everything Heron keeps is erased. Your mailboxes at your provider are left untouched.

Gmail and Outlook / Hotmail / Microsoft 365 with “Sign in with Google / Microsoft”, iCloud, Fastmail and Yahoo with an app password, and any IMAP/SMTP mailbox by entering its servers.
It remembers your mailboxes and preferences so you find them on every device. It also lets Heron notify you, send your scheduled emails on time and bring snoozed emails back, even when the app is closed.
At your provider, as it is today. Heron only keeps an index to show your lists quickly (sender, subject, date, the beginning of the text). Full content and attachments are read from your mail server when you open a message.
They are encrypted (AES-256-GCM) before being stored and are only used to connect to your mailboxes. With Google and Microsoft, you sign in on their side: Heron receives a revocable authorization, never your password.
Yes, at any time from the app’s settings. All data kept by Heron is erased; your mailboxes and messages at your provider stay intact.
