Mailspring Changelog

What's new in Mailspring 1.13.3

Jan 8, 2024
  • On macOS, long-pressing a key to show it's available subtitutions (eg: e to see é, ê, etc.) now works properly in the email composer. Sorry for the delay fixing this issue, for many non-english speakers on macOS we know it's a core part of your email workflow.
  • We now escape subject and participant names in the print modal, ensuring that they render properly for printing.
  • We now use DOMPurify to sanitize the content of HTML emails for display. DOMPurify is maintained by a team of security-oriented web engineers and will ensure Mailspring protects you from the widest possible range of XSS attacks and exploits.

New in Mailspring 1.13.2 (Dec 11, 2023)

  • This is a patch release that fixes several issues:
  • Composition events in Mailspring's composer should work as expected. (Typing modifier keys, such as Option-E followed by E to create É)
  • The composer warn about several more invalid recipient errors correctly (thanks @Phylu!)
  • Dark-mode tray support on Windows has been improved with new icons (thanks @Phylu!)
  • The Linux Snap build no longer requests extraneous permissions (thanks @3v1n0!)

New in Mailspring 1.13.1 (Nov 22, 2023)

  • Mailspring 1.13 now runs on Electron 22, completing a migration process we started in 1.12.0!
  • If you are upgrading from an old version of Mailspring, download and run 1.12.0 first before installing this version. We've moved from keytar to Electron's safeStorage API for securely storing your email passwords, and version 1.12.0 will perform a migration ensuring your passwords are transitioned.
  • If you're using the snap version of Mailspring, you may find that Mailspring forgets your passwords when you upgrade. I'm very sorry for the hassle this causes - issues with snap containment in version 1.12.0 caused Mailspring to lose many user's passwords during the upgrade process. If this applies to you, you may see password errors and need to:
  • Visit Preferences > Subscription and click Setup Mailspring ID and sign back in to your Mailspring account. (You should see an alert at launch that will remind you which email address you'd used for your Mailspring ID)
  • Visit Preferences > Accounts and re-authenticate any accounts shown in red that are having connection difficulty.

New in Mailspring 1.12.0 (Nov 15, 2023)

New in Mailspring 1.11.0 (Jul 30, 2023)

  • Features:

  • "Sync Mail Now" is displayed in Preferences > Shortcuts so it's easier to map it to a custom shortcut.

New in Mailspring 1.7.7 (May 21, 2020)

  • Fixes:
  • Mailspring now ships with OpenSSL-1.1.0f on Windows and Linux, which resolves connection issues with Yahoo and other IMAP providers that recently began requiring newer SSL / TLS features. #1974

  • On Windows, pasting CRLF delimited plain text does not result in newlines being lost. #1756
  • Mailspring no longer fails to connect to SMTP servers on older Linux distros (Ubuntu 14, etc.) that do not have realpath installed. #1974
  • Groups of more than 999 contacts no longer cause “sqlite too many variables” errors during contact sync. #1951

  • Fixes an occasional issue that could cause the people sidebar to become blank if the user's LinkedIn handle was malformed. #1909

  • Mailspring uses relative URLs for it's own assets, so the filesystem path to the application can safely contain characters like # and ? safely. #1366

New in Mailspring 1.7.5 (Apr 17, 2020)

  • Disabling image autoloading now works consistently and also prevents requests for external stylesheets and web fonts that could be used for tracking.
  • Mailspring no longer gets "stuck" creating all drafts and replies in plaintext in some cases. #1894
  • Localizations have been improved for Simplified Chinese and Russian (Thanks @anthonywong, @raven-kg), and @dvomaks added a Ukranian translation! All three have been added to the "verified localizations" list so they're easier to find in the language dropdown.
  • If your machine's hostname contains spaces, Mailspring will strip them when identifying itself to SMTP servers to avoid being rejected in some cases. If it cannot determine your hostname it will fall back to your IP address similar to how Thunderbird works. #1808

  • Mailspring now supports plaintext mail display and composition! It can be enabled via a new setting, or for a single draft by holding Alt/Option when creating it. Most composer features are disabled in ths mode - for more information, check out #52 (comment).
  • Fixes:
  • Mailspring now prompts you to confirm that you'd like to delete folders and labels. #1785

Free users can translate up to 50 messages a week - Mailspring Pro removes the limit and allows you to "Automatically Translate" all messages in particular languages.
  • Note: We're waiting on Google to approve Mailspring for access to the "Read-write Contacts" Oauth scope, so Gmail accounts will be read-only until ~December 2019.
  • Contact Management: Mailspring now includes a full-featured address book available from the Window menu! You can create, update, and delete contacts and contact groups in connected Google and CardDAV-compatible accounts (iCloud, FastMail and others.)

When composing an email, you can now type the name of a group to insert all of the contacts in that group as recipients.

New in Mailspring 1.6.3 (Jul 2, 2019)

  • Drag and drop of files into the composer and drag and drop of threads into folders / labels in the left sidebar now works as expected in all cases. #1533, #1534
  • When typing in Japanese or another language that uses composition events / IME, the composer now always commits your text when the composition dropdown is dismissed. #1531
  • A small "download" icon on the event header displayed in calendar emails allows you to download the underlying ICS file. #1547
  • Resolves top issues reported via our automated error collection, including several problems causing instability in the updated composer.
  • Right clicking an image or file attachment now gives you contextual menu options to save, open or preview the file. #1548
  • You can no longer select a Label as your Gmail "Trash" folder. This was the root cause of several crashes and is not really conceptually supported by Gmail.
  • Mailspring now warns when loading plugins that have not been compiled to JavaScript ahead of time. (We no longer ship TypeScript + Babel because relying on a specific version is problematic and they are 30+ MB)

New in Mailspring 1.6.2 (Jun 18, 2019)

  • Highlights:
  • Mailspring now allows you to RSVP to calendar events directly from your inbox. Messages with .ics attachments or text/calendar mime-parts are displayed in a nice expanded format. The Calendar preview is back and more features are coming soon!
  • A new menu option, "Copy Mailbox Permalink", allows you to generate a mailspring:// URL for a thread. Clicking this link from another application opens the thread in Mailspring. Note: this is separate from thread sharing (public links) and only works on computers with the account synced.
  • The composer is faster, more reliable, and uses significantly less RAM over time thanks to a new version of the SlateJS text editor. You can also drag and drop selected text and drag/copy/paste inline images.
  • Improvements:
  • The message viewer and the composer now stretch the full width of their panels by default. To get the old behavior back, enable "Restrict width of messages to maximize readability." in Preferences > General.
  • Mailspring now supports snapcraft on Wayland properly.
  • In dark themes, copy-pasting text out of an email into the composer will no longer transfer the text color if it's the theme default.
  • The "Attach File" button has moved from the right to the left side of the composer's bottom bar, making it less likely that you'll tap the "Delete Draft" icon by accident.
  • Open tracking now correctly filters out your own tracking pixels so viewing emails doesn't trigger notifications. (This was a regression in a recent release.)
  • The "has: attachment" query now works when combined with other queries and search strings.
  • Sender name validation ("Are you sure you want to send addressed to 'Ben'?") now supports hyphenated names correctly.
  • On Linux, Mailspring handles icon themes without context keys properly. #1467
  • The Dutch and Czech translations have been improved!
  • Mailspring displays a confirmation dialog before resetting accounts and settings.
  • Mailspring now warns if a permission error prevents it from updating it's macOS launch-on-start settings.
  • Incoming attachments without names are now given default names with file extensions inferred from their content type.
  • Mailspring no longer displays some HTML messages with specific styles at a height of 0px.
  • The color picker in the composer now includes a thin border so it's easier to see in all themes.
  • When copy-pasting out of the composer into a plain text destination, newlines and whitespace are preserved in your text and composer copy paste is generally more reliable.

  • On Windows, the font dropdowns in the composer no longer appear white-on-white in dark themes.
  • Select-all and copy paste of email message contents now works reliably in all cases.
  • Development:
  • Mailspring now uses Electron 4.2.4, which includes several security patches and minor bug fixes.

New in Mailspring 1.6.1 (Apr 5, 2019)

  • Fixes:
  • Sync Mail Now now has a keyboard shortcut (F5). Thanks @StarScape!
  • Swipe-to-archive on a macOS trackpad is less "touchy" and ignores interactions that are primarily vertical. #690
  • Mail Rules run on every incoming message and always run after the message body has been fetched, fixing issues with some mail rules not being executed properly. #605, #513
  • The "Check for Updates" menu item no longer causes the app to crash when no update is available.
  • Fixes a regression in removing quoted text via the small "X" that appears over the quoted text marker. #1434
  • Update snapcraft.yml to include gtk-3-themes #1435
  • Spellcheck on large emails with more than 500 distinct words is much more performant thanks to a larger cache.
  • In the composer, you can delete a text selection that includes the first character in the email. (More composer fixes are coming soon - we've been unblocked upstream in SlateJS!)
  • The Japanese translation has been improved. Thanks @kometchtech!
  • The Russian translation has been improved. Thanks @ivan-nginx!
  • Mailspring now uses Electron 4.1.4, which fixes several crashes and an issue on KDE where tray icons would be displayed incorrectly as a 22x22 square cropped from the center.

New in Mailspring 1.6.0 (Mar 18, 2019)

  • The German translation has been improved (Thanks @ahahn94!) and Japanese is now listed as a fully reviewed language!
  • The Linux system tray icon is now larger and brighter when unread, which looks better on most Linux distros. (#1386)
  • Mailspring now shows it's icon in notifications and correctly resolves the icon from your current theme is only supported for Gnome, Mate and Budgie. (Thanks @arkraft!)
  • When clicking the track of a scrollbar, the view is scrolled by one page up or down rather than scrolling to the clicked position.
  • When switching between a mailbox and "Drafts" or "Activity" the left sidebar no longer scrolls back to the top.
  • Preferences styling has been slightly improved.
  • Mailspring now uses Electron 4.0.8 which includes a recent security patch and is recommended for all users.
  • Window controls are no longer “squished” in the darkside theme on Linux #1104
  • Double-clicking the window toolbar on macOS correctly maximizes / unmaximizes the window. #1388
  • When using the Outlook keybindings, Ctrl-F is no longer tied to both "Forward" and "Find in thread". "Find in thread" has been changed to Ctrl-Shift-F for consistency with Outlook.
  • Mailspring strips surrounding quotes from displayed contact namess. #1397

New in Mailspring 1.5.7 (Feb 27, 2019)

  • Fixes:
  • Emails in Gmail accounts no longer "flicker" in the thread list occasionally if you mark them as read and archive them in quick succession.
  • Duplicate sent emails (your copy + the recipient's copy) no longer appear in Gmail when open/link tracking are enabled. Gmail IMAP changed handling of IMAP Delete + Expunge in Sent Mail earlier this month causing this bug. This also resolves issues where viewing a message you sent would trigger read receipts. #1279 #1086 #937 #1162 #1049
  • Mailspring no longer erases all your account passwords when signing out of your Mailspring ID on macOS due to a race condition.
  • Cut/copy/paste and undo/redo now work in the "Create a Mailspring ID" and "Upgrade to Pro" webviews within the app. #15219
  • Mailspring now requests the "internal / received" date of emails to handle providers (including home.pl) which do not return message dates when asked for mailbox headers. This fixes an important issue where all emails could appear to be from 1969.
  • Mailspring now renders inline images attachments within the body of the email even if they're missing an "inline" content-disposition. Previously these images would appear as attachments at the bottom of the message.
  • Mailspring now supports home.pl accounts which advertised support for the IMAP XLIST extension but did not appear to implement it properly.
  • The contact sidebar now opens LinkedIn person profiles correctly - the "/in/" segment of the URL was previously missing.
  • The signature editor now allows you to add a link to your LinkedIn profile.
  • Mailspring shows the "Snoozed" folder name correctly in cases where it's called "Mailspring.Snoozed".
  • Mailspring is now less aggressive about wrapping wide emails and prefers horizontal scrolling for large tables, etc.
  • French translations have been improved (thanks to @Gaspacchio!)
  • Performance:
  • Mailspring now uses DOM ResizeObservers to implement scroll bars and properly size emails as they render which is a huge performance win, especially on slower machines.
  • Mailspring refreshes the data backing the conversation view asynchronously when threads are removed, eliminating jank that was especially noticable if you'd scrolled down in the list and were viewing a unified mailbox.
  • Development:
  • Mailspring now uses Electron 4.0.5.

New in Mailspring 1.5.6 (Feb 12, 2019)

  • Features:
  • Mailspring now generates quick attachment previews of common "code" file types using Prism, including .html, .json, .txt, .log.
  • Italian, Japanese and French translations have been improved (Thanks to @kometchtech, @ecavicc and @gooodmorningopenstack!)
  • Fixes:
  • Mailspring now configures Yandex email accounts on custom domains correctly. #1337
  • Emails that use <style> tags and class attributes without any inline styles are now rendered correctly.
  • Selecting several lines of pasted text and enabling "Code Block" formatting now works correctly. #1346
  • Maispring now plays the "New Mail" sound correctly even if you haven't interacted with the window since the app was launched. (This was broken due to a recent new feature in Chromium blocking web pages from playing audio.)
  • Development:
  • Mailspring now uses Electron 4.0.4 which fixes several memory leaks.
  • A preview of Mailspring's upcoming Calendar feature is available under the Developer menu. Right now, it only supports Google Calendar and the data shown on the calendar is read-only. Stay tuned! The UI was originally developed for Nylas Mail before it was shuttered and we'll be re-launching it this summer.

New in Mailspring 1.5.5 (Jan 4, 2019)

  • Features:
  • Mailspring now shows visual previews of PDF, DOCX, XLSX, XLS, CSV, and Markdown attachments on Windows and Linux as well as macOS. Selecting an attachment in the message view and pressing the space bar or clicking the small "eye" icon shows a preview of the contents in a new window, so you can finally view PDFs, etc. without leaving your Mailbox!
  • Fixes:
  • Mailspring no longer crashes with a fatal error on CentOS, Red Hat Enterprise Linux (RHEL) 7.6 with a "CXXABI_1.3.9" message. When we upgraded to Electron 4, using GCC++5 to build parts of Mailspring resulted in libraries too new for some linux platforms.
  • In dark mode, text in message bodies is no longer black.
  • The copy and cut context menu items are disabled when right-clicking a password field.
  • The Brazillian Portuguese translation has been improved (Thanks @leoescarpellin!)
  • You can now view Mailspring's open source license and all of it's dependencies' licenses and copyright notices from the menu.

New in Mailspring 1.5.3 (Nov 26, 2018)

  • Improvements:
  • Mailspring now defaults to English for languages whose translations have not been manually reviewed by a contributor. You can customize the interface language via a new setting in Preferences > General.

  • Fixes:
  • Mailspring no longer aggressively autocompletes :10 to the :100 emoji, or :12 to the :1234 emoji, to avoid conflicts with typing times. #1148
  • On macOS, Mailspring's spellchecker correctly transitions to the language you're typing in consistent with Linux and Windows.
  • The Emoji picker now works correctly when using Mailspring in a language other than English. #1189
  • Shrinking Mailspring's UI using the "inteface zoom" setting no longer causes spellchecking "squiggles" to become invisible.
  • The "Does Not Contain" mail rule now requires that every item in the field not contain the text as expected, rather than just requiring that any one of the items (senders, recipients, etc.) not contain the text. #1110
  • Mailspring's "Upgrade to Pro" modal no longer appears badly clipped when using a custom interface zoom level.
  • The fixed size "Add an Account" window now ignores custom zoom levels so that fields and forms are not clipped.
  • Development:
  • Mailspring now uses React 16.6 (up from 16.2), which fixes a few critical bugs including a problem where the interface could "lock" indefinitely if too many re-renders were backlogged.

New in Mailspring 1.5.2 (Nov 6, 2018)

  • Improvements:
  • Mailspring now defaults to English for languages whose translations have not been manually reviewed by a contributor. You can customize the interface language via a new setting in Preferences > General.

  • Improvements:
  • Thousands of translations have been improved or manually reviewed. Thanks to @odie2 @pamo @SimonVanacco @louim @DarkSmile92 @phylophyl and @renfliu for contributions across 6 languages!
  • Mailspring now ships Linux appdata files (Thanks @kirbyfan64!)
  • Fixes:
  • Reverts a change to IMAP message parsing that was designed to extend support for Proton Mail Bridge, which caused many emails from some IMAP servers to appear to be from "NIL".

New in Mailspring 1.5.0 (Oct 23, 2018)

  • Features:
  • Mailspring now supports localization! The app detects your system locale and all text, menus, buttons, etc. in the app appear in your language. Mailspring's core strings has been manually localized in 38 languages and the rest (mostly error messages and text describing features) have been automatically translated.
  • We'd love your help improving these localizations! A new "Developer > Toggle Localizer Tools" menu option in Mailspring allows you to submit better translations right within the app. You can also edit the translation files directly and submit a pull request. See the new localizer guide here.
  • If you use a RTL language, Mailspring's entire UI now appears right-justified, including the sidebar, preference panels, scrollbars, and more. If you use Mailspring in Arabic or Hebrew and notice issues in the right-to-left presentation, please file issues or submit pull requests.
  • Fixes:
  • The "contact profiles" feature of Mailspring Pro is much more robust and reliable thanks to a new profile discovery mechanism.
  • The "contact profile" sidebar shows the Gravatar associated with the email address before falling back to the "empty box with initials".

  • On Linux, Mailspring now uses the pixmaps dir to show an icon in the corner of each window. #1135
  • On Linux, Mailspring uses circular icons rather than square ones. #1098

  • Fixes:
  • Mailspring no longer attempts CRAM-MD5 SMTP auth instead of PLAIN or LOGIN when both are supported.

  • The IMAP/SMTP port dropdowns no longer "stick" the first time you change them during setup.
  • Mailspring now lets you know if your SMTP server refused to relay a test message during setup.

  • Open and link tracking now work correctly for accounts using Courier IMAP (where sent messages
  • do not appear until re-selecting the folder via IMAP.)
  • Debugging:
  • Mailspring now prints descriptive SMTP error strings instead of SMTP error codes in logs.

New in Mailspring 1.4.1 (Aug 14, 2018)

  • Don’t allow shift-U, shift-I, etc. to be menu accelerators that override composer bubbling. This fixes a bug where, with the Gmail shortcuts enabled, typing Shift-U or Shift-I in the composer would mark the message as read.

New in Mailspring 1.4.0 (Aug 9, 2018)

  • Mailspring now connects to SMTP servers that only support GSSAPI or Kerberos and PLAIN using the PLAIN method rather than trying to use Kerberos and failing. #341
  • The "undo send" toast in Mailspring now has a countdown timer, and the undo button has been visually differentiated from the background. #872
  • Emails no longer get "stuck" when using undo send in some scenarios. #336
  • Undoing a send of an inline reply during the undo-send time window no longer leaves the composer "locked" or re-sends the original draft. #596, #390
  • Mailspring no longer throws an exception when parsing quoted text for some emails.
  • Removing the last account from Mailspring no longer causes it to return to the "Connect an Account" screen with errors that prevent you from moving forward without restarting the app.

New in Mailspring 1.3.0 (Jul 17, 2018)

  • Mailspring 1.3 brings an overhauled search bar with powerful autocomplete that makes it easier to create advanced search queries:
  • In addition to searching for freeform text and using the Gmail query language (subject:, in:, is:, from:, to:), Mailspring now allows you to search by date using natural language terms like since: "last week" and before: "february 5th". Try combining them with other terms to search a specific time window!

  • The Print window no longer contains an incorrect menu bar on Windows. #958
  • Signatures with Facebook and Twitter profiles now display the service favicons reliably when viewed in Gmail and Outlook. #968

  • The composer cursor no longer gets "stuck" occasionally when typing diatric or multi-key composition characters. #718, #578

  • Clicking to collapse a message with expanded headers now works as expected. #636
  • Mailspring never shows images by default when you're viewing your spam folder. #784
  • Development:
  • The "Download attachments when..." option, which was never implemented in the new sync engine, has been removed from Preferences > General.

  • In the Taiga theme, the selected item in dropdown menus is visible. #674

New in Mailspring 1.1.3 (Feb 6, 2018)

  • Improvements:
  • When adding an IMAP account, Mailspring now uses the domain's MX records to identify if it can use settings for a common email service to skip the full, complicated IMAP settings screen.
  • When adding a Gmail account, Mailspring now uses two-legged OAuth instead of three-legged OAuth which allows it to renew it's access token more rapidly. (Re-authenticate Gmail accounts for this to take effect.)

  • Mailspring no longer becomes "blocked" when ingesting a large number of deletions in a mailbox and will no longer attempt to retrieve many, many new messages all at once.

  • Memory and Performance:
  • Creating a draft is now ~16x faster in scenarios where lots of quoted text is present.
  • The undo history of the composer is cleared when you navigate away from a draft, reclaiming memory.
  • Completed tasks are purged from the app's task queue more rapidly so performing many, many actions on your mailbox does not cause the application to use more memory.

New in Mailspring 1.1.2 (Jan 29, 2018)

  • Fixes:
