Mailbutler News
Mailbutler is here to stay with the macOS Sonoma release!
Your trusted Apple Mail extension, Mailbutler, will continue to work with the macOS Sonoma release.
After his studies in industrial engineering at RWTH Aachen University, Tobias co-founded Mailbutler GmbH together with Fabian in 2015. In his free time, he spends most of his time in the garden and with his son Timo.
We've got some news to share. Your trusted Apple Mail extension, Mailbutler, will continue to work with macOS Sonoma.
With the recent release of macOS Sonoma, Apple introduced several fundamental changes to Apple Mail that significantly impacted third-party extensions. Especially the decision of Apple to cease support for Mail Plug-ins as we knew them. This meant that we had to go back to the drawing board and rethink how Mailbutler integrates with Apple Mail. We've been working tirelessly over the past four months and now we've got good news to share: all 11 Mailbutler features are up and running again.
We’ve had to relocate some features to our Sidebar though and are aware that the change in Mailbutler’s user interface may not be the most convenient adjustment for your existing workflow. Believe us, we share your sentiments. If it were up to us, our design would have remained as you’ve grown accustomed to. However, the modifications implemented by Apple in macOS Sonoma restricted our ability to do so.
The good news? The current design is not set in stone. We're proactively exploring solutions to reincorporate our features back into the native Apple Mail UI, and we already have some promising ideas that we're excited to test and implement. You can find all of them on our roadmap, where you also have the opportunity to upvote existing ideas or propose entirely new ones. Whether it's feature ideas, UI improvements, or any other enhancement you can envision—your feedback directly shapes our development priorities.
Bottom line: The current version of Mailbutler for macOS Sonoma is working and ready to use. The UI however, is not final and constantly being improved with the help of your feedback.
Our advice - wait on Sonoma
While Mailbutler is fully compatible with macOS Sonoma, we recommend exercising patience before making the leap to this new operating system. macOS updates typically bring substantial enhancements and features, but they can also bring unforeseen compatibility challenges with existing software applications.
By postponing your update for a few weeks or even months, you provide a buffer period during which initial bugs or compatibility issues can be identified and resolved by both Apple and third-party developers.
Mailbutler on Sonoma - what has changed
We want to assure you that we've worked diligently to ensure the changes to your Mailbutler experience are as minimal as possible. While the transition has necessitated some very minor changes to our features, we've ensured that the essence of what makes Mailbutler so valuable remains intact. Read on for additional details regarding the changes.
Floating Sidebar
One necessary change that you might have noticed after updating to macOS Sonoma is the relocation of Mailbutler's Sidebar. Apple's recent updates no longer allow us to use the embedded sidebar in Apple Mail. But fear not, because we've come up with a solution – the Floating Sidebar.
The Floating Sidebar is all about giving you control. You can now decide where it best serves your workflow. Do you prefer it right next to your Apple Mail inbox, or would you rather move it around, perhaps even to a second screen? The choice is entirely yours.
To keep the Sidebar firmly attached to your Apple Mail window, like it was in the old Mailbutler version, simply click on the button at the top of the sidebar. It's that easy!
We're eager to hear your thoughts on our new Floating Sidebar. Since this is the first version, we're committed to making it even better based on your feedback.

New location of Smart Send Later, Snooze, Tracking and Message Templates
Due to the changes by Apple to the Mail application, we can no longer show the feature buttons of Tracking, Smart Send Later, Message Template, and Snooze directly in Apple Mail. For this reason, we had to move the feature buttons and they are now available in the sidebar. Only the location has changed; the functionality remains consistent with what you've come to expect. We appreciate your understanding and support during this transition period.
New location of Smart Send Later, Snooze, Tracking and Message Templates
Message-ID
You may have noticed something different in your Apple Mail: a seemingly strange and technical string of characters appearing in each email. This is known as the "Message-ID," a unique identifier generated for every email message. While it may look intimidating at first, it's important to note that only you can see it, and is not part of the email body that gets sent out.
The Message ID is key for Mailbutler's sidebar features like tracking info, notes, and tasks. It links each email to these functionalities.
Message-ID in Mailbutler
Tracking Info
With the changes to macOS Sonoma, we can no longer display tracking check marks in the message list. The email tracking information is now accessible in the Mailbutler Sidebar, right next to your email. We're totally aware that having this information in the Mailbutler sidebar isn't where you'd like it to be. That's why we're currently investigating to find ways to bring the tracking info right back into the Apple Mail app.
Tracking details in Mailbutler Sidebar
The old way of seeing tracking checkmarks right in your message list isn't gone—it's just moved. You can find a similar view in your Mailbutler dashboard, which you can easily access straight from the sidebar. It enables you to see at a glance the status of your emails—indicating which have been opened and which have not. Additionally, the Dashboard offers robust filtering options, allowing you to pinpoint the exact emails you're searching for. While the location of the tracking information may have changed, our unwavering commitment to providing accurate and reliable tracking data remains constant.

Mailbutler Authorization
Apple's new macOS Sonoma introduced some updates that required us to tweak how our extension functions. To address these new requirements, we've developed a feature we call internally "Mail Bridge." Think of it as a bridge that helps Mailbutler to make our features work.
Privacy is very important, especially when it comes to your emails. That's why we it with a "privacy-first" approach. We never read, store, or analyze your emails.
We know that email accounts and configurations can differ wildly, and we've made sure that the authorization process is flexible enough to support nearly all of them. If, in the unlikely event, you encounter an issue during the setup, don't hesitate to reach out to us (support@mailbutler.io). We're committed to making it work for your specific email account.
How to set it up?
The setup process is designed to be a hassle-free experience. The first time you try to send an email using any of Mailbutler's features after the macOS Sonoma update, you'll notice a small window popping up on your screen. Simply follow the on-screen instructions to complete the setup. Don't worry; there's nothing technical or complicated involved. Just a few clicks and you're done!
Once it's up and running, you never have to do it again.
Setting up Mailbutler Authorization
Once you've followed all the steps, you'll see a little button at the top of your Mailbutler sidebar (in the compose window) indicating that the Mailbutler is active. From here, you can deactivate or reactivate Mailbutler at any time. If, in the unlikely event, you encounter an issue during the setup, don't hesitate to reach out to us (support@mailbutler.io).
Sidebar enable/disable Mailbutler
If you're curious to know more about how Mail Bridge works, we've got just the resource for you. Our CTO, Fabian, wrote a comprehensive blog post that goes into the details of what exactly happens when you use Mailbutler.
Discontinue of Undo Send
As Apple is now providing a built-in Undo Send feature, we decided to stop the support for our Undo Send feature on macOS Sonoma. As this feature was already a free extension, which had to be installed as a separate plug-in and wasn’t part of the Mailbutler feature suite anymore, you are not losing any functionality from your paid plan.
To start using Apple Mail’s Undo Send feature, simply launch the Apple Mail application and go to the "Mail" menu in the top-left corner of your screen. From the dropdown list, select "Preferences." Navigate to the "Composing" tab and look for the "Undo Send" option. Check the box next to it to enable the feature. From there you can select from three options: 10 seconds, 20 seconds, or 30 seconds. This is the time window you'll have to cancel the email after hitting "send." You should now see a small "Undo Send" button at the bottom left of your Apple Mail interface after sending an email.
Undo Send in Apple Mail
Summary
First and foremost, thank you for your unwavering support and patience as we navigate through the complexities introduced by macOS Sonoma. While we've had to adapt to new guidelines, our mission hasn't changed: to make your email experience as efficient and hassle-free as possible.
Your feedback has always been the cornerstone of our development process. That's why we encourage you to visit our Roadmap page to upvote features and propose new ideas. With your help, we're not just responding to changes; we're setting the stage for new, user-driven innovations.

we tested the demo and were in the process of purchasing the software but now we don’t know what to do because we would have to upgrade our macs to the new operating system soon anyway. We are just waiting for the first MACOS update to fix the major problems and then we will install it. A public release estimate would be helpful to assess things well.

Hello Tobias – I’m not sure this is the best message “we kindly suggest postponing your update to macOS Sonoma.” Mac users will upgrade, and I have a sense there are many users in my position – upgraded and patiently waiting for Mailbulter. Don’t make us wait too long.

To ensure a smooth experience, we kindly suggest postponing your update to macOS Sonoma for a short period. This will allow us to finalize our adjustments and ensure optimal compatibility.
But getting this info after the automatic update to the neu system is helpless? How long does is due, till the new version is ready? This would help indeed!

Can we at least get an estimate of the timing? If it’s a few days I’ll hold. if it’s weeks out I’ll forgo the Mailbutler features for a bit. You have to have some estimate or target that you’re working towards. ASAP doesn’t really inform or answer the question.

Is there a possibility to mention a timeframe since you mention that you are very close to make mailbutler fully compatible with MacOS Sonoma. Are we talking days, weeks or months.
This could be important for some users because they have to make decisions what to do if they need to upgrade to Sonoma because of other apps they use that need this upgrade.

What I do not understand is that the Sonoma Beta version has been available to software developers like you Mailbutler since the 5th June 2023 (more than 4 months ago).
1. Why has this incompatibility info only been communicated when the Sonoma public release was announced?
2. I never received an email about it – it was just by chance that I saw a message on the Mailbutler interface (which is not there anymore)?
3. Also, you must at this time (October 12 2023), after more than 4 months of development, have a timeline as to when you will resolve the Mailbutler features compatibility issue with the Sonoma OS?

Developer preview is awful. Send later & tracking does not work for 3 of the 5 accounts I’m using. All the features are removed out of the Apple Mail interface (so the tracking icons, contact posters, send later and snooze buttons) and need to be done through the separate popup, which is very cluttered and inconvenient. I’m going to cancel my subscription.

Hi Bas, I’m very sorry that you are having issues using Mailbutler on macOS Sonoma. Please note that currently Mailbutler for macOS Sonoma is still in its beta stages and we are still constantly working on improving the experience. As to your issues with Tracking and Send Later: This is most likely a bug and we would like to further investigate it. Please send an email to support@mailbutler.io and we will look into it. As to the “separate popup”: The pop up can actually be pinned to your Apple Mail window, so that it’s always glued to it, just like the old built-in sidebar. Thanks and get in touch if you have any other problems.

I need to be able to click on the notification I get that shows up on my iMac desktop when someone clicks on an email I sent them, and have THAT sent email open, like it USED TO. When will that be happening? If it’s already happening for others, it certainly is not happening for me.

It would be useful to have a sound message when an email is opened by the recipient.

Hi Enrico, you can receive desktop notifications from Mailbutler to notify you that your emails has been opened by your recipient. For a sound to be played when you receive a Mailbutler notification, you would need to go to System Settings > Notifications > Mailbutler and activate “Play sound for notification”.
