Custom Newsletter Addresses

by Ben Ubois

There’s a few new features for your newsletter address.

  1. Create unlimited addresses. First up, you can now create newsletter addresses. There’s a couple reasons you might want to do this:
    • Automatic categorization with a different default tag.
    • To prevent spam. More on this later.

    If you’re familiar with Apple’s Hide My Email or Fastmail’s Masked Email, then it’s like that, but for your newsletters.

  2. Customizable addresses. You can now choose a custom prefix for your address. This can help with making something more memorable or as a note to yourself what the address was created for.

  3. A new domain. All Feedbin newsletter addresses now use an domain. This was changed because it’s much shorter and nicer looking. Newsletters addressed to will continue to work too.

There is an unfortunate reality of email newsletters. Since running a fairly large inbound email service, it’s come to my attention that newsletter addresses accidentally leak (or get sold?) to spammers. To combat this, you can now deactivate an address entirely. I consider it good email hygiene to use a unique address for every newsletter you sign up for.

There’s a couple ways to do this:

  1. Generate a custom (or random address) on the website.
  2. Use a “plus hack”. Say you have the email address You can also receive newsletters at or This way you don’t have to create a new address ahead of time. If this address ever gets out, you can disable it entirely.

Airshow Updates

by Ben Ubois

There’s an Airshow update available now. It includes a number of powerful new features, upgrades, and polish.

  • Interactive widget: Playback controls right on your Home Screen. The design is richer and now includes more useful information.
  • Download filters: Download just the episodes you want with keyword filters.
  • Skippable chapters: In the chapters view you can preselect chapters you want to skip.
  • Chapter filters: The only thing better than skippable chapters is being able to automatically skip chapters that match keywords you specify.
  • App icon: A beautiful and fun new concept designed by Matthew Skiles.
  • Polish: There’s a simplified scrubber in addition to multiple layout fixes and improvements especially on iOS 17.

Finally, Airshow now has its own website.

Fixable Feeds

by Ben Ubois

There’s a new set of features available on Feedbin with the goal of helping you find and fix broken feeds.

A fairly common reason for a feed breaking is when a publisher moves their feed, but does not redirect the old one to the new location.

Feedbin continuously monitors feed health and is now able to use this data to see if a healthy alternative exists.

For example a feed I subscribe to moved. Visiting the old one results in a “404 Not Found” error. Feedbin was able to detect that they still advertise feeds on their website and offers the option of replacing the broken one.

Visit your subscriptions page to get started. There will be a notice at the top of the page if Feedbin has detected any broken feeds it can help with.

This same feature can also help with OPML imports. For example if your OPML file includes an outdated link, Feedbin will automatically check for working alternatives.

Airshow 2.0

by Ben Ubois

Airshow 2.0, Feedbin’s podcast app for iPhone and iPad, is out now.

This release aims to address all the most common feature requests and some surprises. This includes:

  • Playlists: Airshow takes a streamlined approach to playlists. Most podcast players make playlist management in the same style as a music playlist. You subscribe to some shows, then you create a playlist separately.

    However podcasts are different. You typically only listen to an episode one time, so there’s no need to manage playlists separately. Instead, Airshow lets you choose or create a playlist when subscribing to the show, making it a one step process to add a new show to a playlist.

  • Speed Controls: People really like listening to podcasts faster than real-time.

  • Sleep Timers: Another common request, now available right on the player screen.

  • Download Manager: See and manage your downloads in one place. This is also helpful for surfacing download errors.

  • Mini Player: This makes it possible to see what’s playing and control playback from anywhere in the app.

  • More Chapter Art: Chapter specific artwork is now displayed on the lock screen during playback.

Twitter Access Revoked

by Ben Ubois

Feedbin’s Twitter access was revoked because “this App has violated Twitter Rules and policies.” Which is the same message many Twitter clients received in January when Twitter first started turning off API access.

Twitter does not want any kind of third-party client accessing its data. While it looked like there might be a path forward at one time, it’s now clear that there is not.

This means the end of Twitter support in Feedbin. Feedbin will no longer be able to fetch any new content from Twitter, but anything that you have already subscribed to will stay put.

I could tell you about the benefits of using open alternatives like RSS or Mastodon instead, but if you’re reading this, you already know.

Push Notifications for All Browsers

by Ben Ubois

Feedbin has long supported sending yourself a push notification from an Action. Previously this was available in Safari only. However as of Safari 16, most browsers support the standard Push API, so Feedbin now uses this for notifications. This makes the feature more widely available.

Push notifications can be intrusive, so why support them at all? I think Feedbin is in a unique position to get you exactly the notifications you want. A website that offers notifications will likely send you a notification for everything that is published, but with Feedbin you can narrow this down to a single source or search.

It also enables notifications for any website with an RSS feed, not just the sites that implement notifications.

Here’s how to set it up:

  • Create an Action.
  • Switch on the option to “Send a Push Notification.”
  • Click the link to “Enable push notifications” below the switch.

The Plan for Twitter

by Ben Ubois

A lot of customers have asked about the future of Twitter support in Feedbin. Even with today’s update there’s still not enough information to make a decision.

Feedbin’s priority is to keep the stuff that you subscribe to up-to-date, so the plan is to continue to use the API. However, it also depends on what the price ends up being:

  • If it’s cheap, Feedbin will just pay the fee and everything will continue as usual.
  • If it’s expensive, Twitter support could be available as a paid feature.
  • If it’s very expensive, say to the point where the paid upgrade price would cost more than a Feedbin subscription, Twitter support will likely be removed.

Finally, it’s unclear to me if Feedbin is even a valid product category according to the new rules. All this does not matter if they decide to revoke Feedbin’s access.

As I write this, Feedbin can’t connect to Twitter’s API. It returns a “Too many requests” error for every attempt. It looks more like a bug based on the other wide-spread Twitter issues from the last few days.


Follow Feedbin on Mastodon

by Ben Ubois

Feedbin now has a Mastodon account, you can find it here: You can also subscribe right in Feedbin using the new integration.

I was impressed with the set-up experience using the official image in the Digital Ocean Marketplace. Much like a website or email address, you get the most flexibility when you use your own domain for any web presence, and the Mastodon team has made that easy.

Search Upgrades

by Ben Ubois

Search has been improved at every level, with new features, software, and hardware. Oh, and it’s about 10 times faster.


There’s a nice new way to search within a feed or tag. When you start typing in the search field, Feedbin will suggest sources to search within. Choosing one of these sources will filter the search to only find results within your selection.

When you already have a feed or tag selected in the source column, the search field will be automatically scoped to the selected source.

There’s also a few new fields that you can use to find exactly what you’re looking for.

You’ve long been able to search by the published date, but this field has a new feature: relative dates.

For example, if you want to set up a saved search to see all your unread articles that were published in the last 24 hours, you could use the query: published:>now-1d is:unread. You can also search for a range. For example if you want all unread articles that were published yesterday, this is how: published:[now-2d TO now-1d] is:unread

Next up, link. Link can be used to search for the presence of links to specific domains. To find an article that links the the New York Times you could search for Link is also fully subdomain aware so you could search for This field supports the ability to search for multiple values, like link:( OR

Feedbin has become omnivorous in terms of the types of content it ingests. To reflect this direction, search has gained the ability to filter by type. These are the types you can search for:

  • feed
  • newsletter
  • podcast
  • twitter
  • youtube

For the podcast and youtube types, there’s another new field: media_duration.

Say you’re as old as I am, and you never want to see a “short” in your YouTube subscriptions. You could create an Action that marks matches to this query as read:

type:youtube media_duration:<120

Check the Search Syntax help page for the full documentation.


To power all of this, the search infrastructure was upgraded as well. Feedbin had been using an ancient version of elasticsearch. This was showing its age with poor performance and flaky reliability. Upgrading to elasticsearch 8 fixed the reliability, but the performance still wasn’t great. The 95th percentile response time for a search was hovering around 1.5 - 3 seconds.

To remedy this, a hardware upgrade was needed. These are the specs for the new search server configuration:

  • AMD Ryzen 5950x (16 3.4GHz cores)
  • 128GB RAM (DDR4-3200)
  • 4TB storage (PCIe 4 NVMe)
  • Mellanox 10Gb NIC

Feedbin’s application servers were upgraded to use Ryzen 5000 series CPUs back in 2021 and I’ve been happy with the performance. They’re clocked higher than most EPYC or Xeon parts and don’t come with the premium price tag or high power requirements. The 5950x comes with 16 cores and 32 threads, so it’s actually great for highly concurrent server configurations, as you’re not giving much up in terms of core count.

Once this new configuration was installed at Feedbin’s datacenter, search performance improved dramatically.

The response time is now consistently under 200 milliseconds.
