- Web app 0.27.0
Spell check, Send feedback, sidebar counts and provider logos
Spell check in English and Greek, feedback from the app, the counts you choose beside each sidebar item, providers' logos on their mail, Analytics in tabs, and Mine now includes your own mailboxes.
New· 17
- Spell check
  In English and Greek as you write, with careful auto-correct, all on your device.
- Send feedback
  Report a problem or suggest an idea from the account menu, with screenshots if you like.
- Sidebar counts
  Right-click any sidebar item to show its unread count, its total, or both.
- Provider logos
  Mail from Gmail, Outlook, Yahoo, iCloud, Zoho and other providers shows their logo.
- Spelling, step by step
  Misspelt words get a dotted underline in messages, team chat, notes, templates and signatures. Click one for suggestions, or add it to your dictionary. Administrators keep a list of the organisation's own words, such as product and client names. On a computer, common typos are corrected as you type, and Backspace undoes it. Nothing you type leaves your device to be checked. Settings › Writing › Spelling.
- Help and support
  In the account menu, our support page with the docs and how to reach us.
- Problems and ideas, step by step
  Choose a problem, an idea or anything else, write what happened or what you would like, and add up to three screenshots. Technical details help us find a problem and never include your mail, contacts or files. Written offline, it is sent once you are back online. We reply by email.
- Unread, total or both
  Right-click a view, a label, a team, a mailbox or a view inside a mailbox, or long-press it on a phone, and tick Unread count, Total count or both. "24 / 186" shows both, and hovering says what each number is. Your choice follows you to every device, and Reset to default in Customize sidebar clears it.
- Mark all as read
  In the same menu, mark everything in a view or a whole mailbox as read, with Undo.
- Logos you can trust
  A provider's logo shows only on mail that proved it came from that provider, so a forged @gmail.com address keeps its initials. Colleagues keep their own faces.
- Contacts first when you write
  In To, Cc and Bcc, your contacts come first, with their company, before the people you have written to and your colleagues.
- Merge two contacts
  Merge with… on a contact's page makes two contacts one, keeping every address, phone and note, and asks you which value to keep where they differ.
- The contact card
  Administrators choose which two custom fields the contact card shows, in Settings › Contacts › Fields.
- Company from the signature
  Add to contacts fills in the company from the sender's signature when it is clear, and leaves it empty when it is not.
- Template values you can see
  In a message from a saved reply, the values filled from a contact are underlined until you edit them, and an empty contact detail is pointed out before you send.
- Analytics in tabs
  Settings › Analytics now has Overview, Speed, Workload, Mailboxes and People, each opening with one plain sentence about your numbers. Filter by a mailbox or by a person; members see everyone's totals or their own.
- Mailbox icons on mail they sent
  Mail a shared mailbox sent shows that mailbox's icon, round like every other face, in the list, the conversation and drafts.
Improved· 7
- Mine includes your own mailboxes: in Inbox, Open, All mail, Closed, Sent, Drafts and a label's or a team's view, Mine now shows everything in your private mailboxes as well as what is assigned to you.
- Reply times in your opening hours: once your organisation has saved its business hours, every reply time counts open hours only, so mail that arrives on Friday evening and is answered on Monday morning is not counted as two days late.
- Company icons for more senders: many more companies now show their icon, including sites with large home pages that were missed before. Senders already in your mail are checked again over the next hours.
- Nobody taken off silently: when merging conversations takes someone off a conversation, they are told, and Activity names them. Undo takes both back.
- The Inbox's empty message now says what lands there: mail to your own mailbox and conversations assigned to you. A shared mailbox's new mail waits in its own Inbox until someone is assigned.
- What's new no longer grows taller than the window, and scrolls inside.
- Settings › Appearance › Message counts now covers only the small badge on a conversation with more than one message. The sidebar's counts are chosen by right-clicking an item.

- Windows 0.3.0
DMU Mail for Windows 0.3.0
Sign in with Google, Microsoft or Apple through your browser, and a message in its own window closes once it is sent.
New
- Sign in with Google, Microsoft or Apple
  The Windows app opens your browser to sign in, and DMU Mail comes back by itself.
Improved
- A message you write in its own window closes once you press Send.
25 Oct 2026
- Web app 0.26.0
Automations, contacts, filters and the details panel
Automations with business hours, contacts, a details panel, filters and saved views, merging, permissions, large files as links, and a What's new window after each update.
New· 48
- Automations
  Rules that sort, assign and answer mail as it arrives, in Settings › Automations.
- Business hours
  Your opening hours, time zone and holidays, for automations and automatic replies.
- Contacts
  Shared contacts for the whole organisation and personal ones of your own, in Settings › Contacts, ready for your saved replies.
- Details panel
  Press i to see the person you are writing with: their contact, your other conversations with them and the files you have exchanged.
- Filters and saved views
  Filter and sort any list, combine conditions, and keep what you use as a view in your sidebar.
- Merge conversations
  Drag one conversation onto another to make them one, with Undo.
- Rules, step by step
  When / if / then rules for your mailboxes: assign new mail to a person or take turns in a team, add labels, close, snooze, move, send an automatic reply, or remind the team when a customer has waited too long. Test a rule on recent mail before you switch it on.
- Opening hours and holidays
  In Settings › Details, set your opening hours, time zone and closed days, with Greek public holidays added in one click. Automations use them for "outside business hours" and for waits in working hours.
- Your contacts
  Everyone in the organisation sees and edits the shared contacts; personal ones are yours alone, and administrators cannot see them either. Search by name, company or address, and the sender's card on a message offers Open contact or Add to contacts.
- Custom fields
  Administrators add fields such as Account number. Use them in saved replies as {{contact.key}}, and they fill in from the first person in To who is a contact.
- Import contacts
  From a CSV, vCard, JSON or XML file, with column matching, or from the people you have written to. Contacts that already exist are updated, never duplicated.
- Opening the details panel
  The (i) button beside a conversation's labels, or the i key, opens it. Someone who is not a contact yet can be added from there.
- Conversations and files with them
  In the details panel, your other conversations with the person, in this mailbox or every mailbox you can see, and the files you have exchanged, each with a search. Click a file to preview it. A part with nothing in it starts folded.
- New conversation
  The chevron beside New message, or Shift C, starts a conversation with nothing sent yet. Give it a title, assign it, mention people and talk it over in team chat; only you and the people you bring in can see it. When you are ready, choose its mailbox and write a draft, or press D. The first one you send makes it an ordinary conversation.
- Filters
  The Filters button beside the search box filters any list by Unread, Has attachments, Important, Mentions me in team chat, mailbox and assignee. Each filter shows as a chip you can remove. Shift F opens it.
- Sort
  Newest, oldest, unread first, largest, smallest, date received, or waiting longest for our reply.
- Advanced filters
  Combine up to 16 conditions with all or any, sort by up to three levels, and see how many conversations match as you go.
- Saved views
  Save a set of filters as a view in your sidebar, then rename it, move it or delete it.
- Everyone / Mine on every list
  Inbox, Open, All mail, Closed, a label's or a team's view, and a shared mailbox's own lists can show only the conversations assigned to you. In Sent, Mine shows what you sent; in Drafts, your own drafts. Each list remembers your choice, and a saved view keeps it too.
- Merging, step by step
  Drag a conversation onto another in the same mailbox, or use Merge with… in the right-click menu, and choose which subject, assignee and status to keep. Messages, notes and team chat combine by date, labels come along, and later replies land in the merged conversation. Undo for a few seconds, or split a message back out later from its ⋯ menu.
- Move and merge
  Drop a conversation onto one in another mailbox to move it there and merge, with a clear note of who gains and who loses access.
- Who can see a mailbox
  Share a mailbox with everyone, or tick any number of teams and individual people. Administrators always see shared mailboxes, and a summary says who can see it. If someone would lose a mailbox where they have conversations assigned, DMU Mail asks first and then unassigns them.
- Mailbox icons
  In a mailbox's settings, choose an icon, an emoji, the organisation's logo or an uploaded picture, on grey or one of nine colours. It shows in the sidebar, the mailbox's page, the Move menu, the conversation's mailbox chip and Settings. Administrators change shared mailboxes, and you change your own private ones.
- Preview more kinds of files
  IPhone photos (HEIC), SVG pictures, videos and audio, Excel and OpenDocument spreadsheets, attached emails, ZIP archives, Markdown, HTML, text, CSV and code all open in the preview. Office documents still download.
- Inside archives and emails
  Open a file inside a ZIP or an attached email without downloading it, and come back with one click.
- Formatted or source
  Markdown and HTML files open formatted, with a switch to see the source. DMU Mail remembers your choice.
- Block a sender
  From the Spam menu, block the sender or everyone at their domain. Their mail never reaches DMU Mail, not even Spam, and is moved to the Trash at your provider so nothing is lost. Nobody is ever sent a bounce.
- Pinned conversations
  Pin up to 10 conversations to a new Pinned group in the sidebar, from a conversation, the right-click menu or P.
- Trackers blocked
  Tracking pixels are removed from every message, even when you show images, and a small icon on the message lists what was removed.
- Labels inside labels
  Put a label inside another, up to three levels. A group shows everything inside it, its count covers all of them, and a search for label:"Clients/Kyma Logistics" finds one by its path. Drag labels in Settings to nest them.
- Pull to sync
  On a phone or tablet, pull any list down to check all your mailboxes now. It says when everything was last up to date, and works offline without errors.
- Sync from the account menu
  Sync checks every mailbox you can see, shows the time of the last sync, and tells you if a mailbox could not be reached, with a link to its connection page.
- Import queue
  Imports of old mail run on their own now, so they never hold up new mail. An import that has to wait shows its place in line and roughly when it will start, and you hear when it begins.
- Many attachments
  A message with many files shows two rows of them, with the count, the total size and Download all. Show all opens the rest.
- Assign, at any size
  Search people, see who in the mailbox's team can already see the conversation, and who would be able to once you assign them.
- Mark as important from the top bar
  A star in the conversation's top bar, filled when it is important.
- Group alerts
  Each mailbox can choose whether automated alerts with the same subject join one conversation.
- Contacts API
  Read and write contacts, add or update one by email, send up to 1,000 in one call, and get webhooks when contacts change. An API key reaches your personal contacts only if you turn that on for it.
- Large files as links
  A file that would take a message past 25 MB, up to 2 GB, is sent as a download link instead. Choose how long it lasts and add a password if you like; the person you write to downloads it from a simple page in English or Greek. You can turn a link off at any time, and it then stops working.
- File links in the details panel
  The details panel lists the files you have sent the person as download links, with how long each lasts and whether it was downloaded, and turns one off in a click.
- Large files settings
  In Settings › Storage, administrators choose whether large files go as links, the longest a link may last, and whether every link needs a password.
- Permissions
  Settings › Permissions lets administrators choose who can do each thing, such as assigning others, moving shared mail to Trash or Spam, managing labels, shared contacts and saved replies, trusting senders, editing signatures, inviting people and sending large files as links. Each can be for everyone, administrators only, or chosen teams and people.
- A page for each person
  In Settings › People, open someone to see their details, their teams and what they can do.
- What's new
  After an update, a short window shows what changed, on phones as a sheet from the bottom. Open it again any time from What's new in the account menu, where a dot marks a new release.
- Sign in with Google, Microsoft or Apple in the Windows app
  Finish signing in in your browser and DMU Mail comes back by itself. It needs the Windows app's next update, which arrives on its own.
- Moving shared mail into a private mailbox
  Now a permission in Settings › Permissions, for administrators by default. Each such move is recorded in Activity.
- Contacts change feed
  The API's contacts:read can follow every change to contacts and fields, deletions included, without missing one; and administrators' API keys can add, change and remove custom contact fields.
- Snooze from the right-click menu now offers In… and Pick date & time….
Improved· 26
- Every feature during the beta: while DMU Mail is in beta, every organisation can use every feature, Analytics included, whatever its plan.
- Mailbox settings in tabs: General, Access and Connection, each with its own link, with the mailbox's name and status on every tab. Members see the same tabs, read only.
- Leaving a team: taking someone out of a team, or deleting a team, now says whose assigned conversations are affected and lets you choose to unassign them or keep them on those conversations.
- The conversation's actions stay pinned on the right, so they never move when someone is assigned, with Trash right beside Close and Snooze next to it. On narrow screens the less used ones fold into the More menu; on a phone Unread, Move, Important and Spam are in the ⋯ menu, and the back arrow does what the × did.
- Spam is a menu in the top bar, on the outside mail notice and in the right-click menu.
- The conversation's top bar shows one group of faces: who is here now, then who can see it. Its popover has a search and says why each person can see the conversation.
- With more than ten shared mailboxes, the sidebar groups them by team, with your teams open first and the others folded with their unread counts. You can turn this off in Settings › Appearance.
- Move groups mailboxes by team, @mentions say whether each person can already see the conversation, and Settings › People has a search and a team filter.
- The preview shows that a file is opening instead of a blank page, with progress for large files, and you can download while you wait.
- Pictures in a conversation can be paged through, zoomed and rotated, and the strip lists every attachment in the conversation.
- A draft's attachments fold after one row, and a meter shows how close the message is to 25 MB.
- In Trash, Delete permanently now sits right beside Restore.
- Alerts and notifications start their own conversation instead of joining an older one with the same subject, and they no longer reopen a closed conversation.
- A new reply from outside brings a conversation back from Trash.
- A conversation you start and leave untouched is discarded when you leave it.
- People who leave a team, or whose team is deleted, stop getting notifications for mailboxes they can no longer see.
- Blocks made automatically from spam reports, and blocks for everyone that members made before, send mail to Spam as they did. Only administrators can block a sender for everyone.
- Block is not offered on a message that failed its sender check, so a forged message can never get a real sender blocked.
- Signatures in Settings work properly on phones.
- The bar of a message that is still in its undo seconds says Undo.
- Esc closes only the menu or popover that is open, not the whole conversation.
- The right-click menu stays inside the window on narrow screens.
- Shared mail stays where the team can see it: a conversation that was ever in a shared mailbox needs the Trash or Spam permission to be removed, wherever it is now, and someone who was only brought into a conversation cannot move it out of its mailbox.
- For developers: GET /api/v1/contacts now returns your contacts. The list of people you have exchanged mail with, which that address used to return, is now at GET /api/v1/correspondents.
- In a Windows browser, the account menu offers the Windows app, which does more than installing the website as an app.
- When you select several conversations, the faces under the count show each sender's company icon, as the list does.
Fixed· 6
- Assigned to me could show a number while its list was empty, because it counted a snoozed conversation. Snoozed conversations are no longer counted there, or in a team's number, until they come back.
- Folding a date in the list no longer loads that date's conversations. The list carries on with the ones after it, and the date shows how many it holds.
- Message bodies on phones no longer stay blank in the cases we could find.
- Date headings in the list draw a single line.
- The details arrow beside "to" sits on its line.
- Sending from a message opened in its own window shows the Sent toast, with Undo, in the main window, instead of losing it as the window closed.

Company icons, tidier messages, and joining with Google or Microsoft
Mail from companies shows their icon, messages start with one line before your signature, and invitations can be accepted with Google or Microsoft.
New· 7
- Company icons
  Mail from a company writing from its own domain shows the company's icon instead of initials, once the mail proves it really came from that domain. Companies that wrote to you in the last six months get theirs too. Gmail and other free mail, colleagues and companies without an icon keep today's look.
- Join with Google or Microsoft
  An invitation link you were sent can be accepted by signing in with Google or Microsoft as the invited address, instead of typing the emailed code.
- No-reply heads-up
  Writing to an address nobody reads, such as noreply@, shows a gentle note under the recipients.
- Drop files to reply
  Drag files onto an open conversation to start a reply with them attached.
- A message waiting out its undo seconds now shows in Scheduled, with Send now and Undo.
- Click a notice about a conversation, such as Sent or Moved to Spam, to open it.
- Invitation emails and the join page follow the language of the person who invited you.
Improved· 6
- A new message or reply opens with one line for you to write on, then your signature, instead of several empty lines.
- Messages you send no longer start with empty lines.
- Every menu, from the account menu to Label, Move and Snooze, now has the roomier spacing of the message menu.
- Organisation logos and people's photos are kept by your browser, so the organisation switcher and avatars no longer load again each time you open them.
- The address in "Starts new messages and replies on" in Signatures is shown in full.
- Initials on mailboxes and people use letters only, so "Development | DMU" shows DD.
Fixed· 4
- Collapsed messages you sent show the start of what you wrote again.
- The Moved to Spam notice goes away once you choose Not spam.
- A team's view moves on to the next conversation when the last team member is taken off it.
- The nightly clean-up of old mail is recorded in Activity with what it deleted.

Assign to me, and spam kept apart
Take a conversation in one click, and spam stays out of your other views.
New· 3
- Assign to me
  The assign button in a conversation takes it for you in one click, and its arrow lists everyone else.
- Team counts
  A team in the sidebar shows how many open conversations it has, and a search in a team’s view stays in that team.
- Webhooks
  A webhook can listen to chosen mailboxes only, and hears about renames, snoozes, moves and access changes too.
Improved· 4
- Spam stays out of Important, Sent, the Assigned views and All mail.
- A change to your sidebar shows on your other devices at once.
- Deleting old mail keeps a conversation with recent team chat or notes, and a snoozed one until it wakes.
- Show original on a message you sent includes its Bcc.
Fixed· 2
- Mail with a wrong or very old date is placed by when it arrived.
- The To field stays beside its label while suggestions are open.
17 Oct 2026
- Web app 0.6.0
Replies bring conversations back
A reply to a closed conversation opens it again, and what needs you comes to the top.
New· 2
- Reopened by a reply
  A reply to a closed conversation opens it again, and so does a bounce of your reply. Out-of-office replies don’t.
- After you reply
  A conversation nobody has is assigned to you, and your reply closes it once it has gone. Both are on by default. Change them in Settings › Writing, or for one reply with Close after sending.
Improved· 4
- Being assigned, a new team chat message, reopening and a snooze waking bring a conversation to the top of the list.
- A reply you send brings its conversation to the top once it has gone.
- The list stays in order as mail arrives and conversations leave it.
- On phones and tablets a message appears at once, without fading in.
Fixed
- Lines in a conversation’s history sit among the messages, in time order.

Invite links, teams and signatures
Copy an invite link to send yourself, give each team a page, and fill signatures from people’s details.
New· 4
- Invite links
  Administrators can copy an invitation’s link and send it themselves. The invited person confirms their address with a code.
- Teams
  A list of your teams, and a page for each one with its members and what’s filed under it.
- Signatures
  Your organisation chooses the details signatures use, each person fills in their own, and every signature fills in the right ones, in Greek or English.
- Attachment size
  A warning when your attachments are too big for most mail providers to accept.
Improved· 2
- DMU Mail starts faster, and a conversation opens in a single request.
- A message is prepared for reading once, when it arrives, so it opens at once.
Fixed
- An invitation expires after a week, also for someone who already has an account.
