How Stefan Judis Uses Buttondown

Stefan Judis teaches thousands of developers using Buttondown every week

Stefan's a long-time Buttondown user and longer-time frontend developer. He's scouring the web to learn more about core frontend technologies and sharing them with his subscribers at Web Weekly.

As a subscriber of Web Weekly myself, it was a blast to talk with Stefan about how his newsletter stands out from the pack and what he's learned along the way.

To kick things off, give me a sense of your background. Who you are. What your day-to-day job is. What are some of the things you're interested in now?

I'm Stefan. I was born and raised in Germany. I live in Berlin. I've been doing JavaScript stuff since — I don't know, I feel like I've lost count at this point. Maybe I'm closing 15 years with a background in frontend engineering. Seven or eight years ago I started blogging and getting involved in the community in Berlin. And because I spend a good chunk of time reading Frontend news, I thought why not start sharing the good things “officially”,

At first it was just monthly — "Stefan Judis' newsletter", kinda thing — and then I saw that the domain was free. It was like, "should I rebrand? Should I buy the domain?" At the end, I did it with the assumption that it looks more serious; it looks bigger than it maybe is, and that it looks more official than a Weekly Newsletter from a random stranger on the internet. Since then, I have done this newsletter thing on a weekly basis, and it is going well!

Many people know how to do something with React, Vue, Angular, or whatever you want to call it — but don't know anything about the underlying bits, like the DOM and HTML. I want to reach people who are interested in that.

Can you talk a bit more about the type of content you try to cover? What is your ideal subscriber? What do they look like? What information and links are you trying to curate for them?

The ideal subscriber of Web Weekly is someone who is curious to understand how things work. My incentive isn’t to know and share how to do ABC with Framework DEF, but rather, understand how the web works.

I, for example, talked to a lot of people and did some workshops, teaching, and boot camps in Berlin. There is an astonishing amount of people who are very good at frameworks. I think the web industry is on its way to the next abstraction layer. Many people know how to do something with React, Vue, Angular, or whatever you want to call it — but don't know anything about the underlying bits, like the DOM and HTML. I want to reach people who are interested in that.

If I sit in front of my computer, and I'm like, "huh, that's new" — I can’t be the only person. This is how I want to progress. So an ideal Web Weekly edition, for me, includes something I learned. And I see huge value in sharing nerdy details and fundamental web dev facts.

Going back to the shift from monthly to weekly, can you talk about why you made that shift? You mentioned it can be hard keeping up that publishing schedule.

If you run something monthly, your subscriber base will grow very slowly. Eventually, it almost felt like it’s not worth it. The impact was too low and I wanted to see results. Also, very few people wait for or expect a monthly email. 😅

I started doing it weekly with the idea to grow it faster and maybe start making some money out of it.

I think there is a misconception out there — "oh, just because I used to work in DevRel means I must get thousands of subscribers just by sneezing". It's still hard! There's no magic bullet.

Where do most of your subscribers come from these days?

Without doing anything, I can see something between two and six subscribers per day coming from my own domain at So there is organic growth. If I had the time, enough money, and energy, I probably would double down on the social thing and ads.

I think there is a misconception out there — "oh, just because I used to work in DevRel means I must get thousands of subscribers just by sneezing". It's still hard! There's no magic bullet.

But speaking of "organic growth", it can be such a loaded term. Organic growth does not equal organic growth because if a person with 100,000 Twitter followers grows their list organically, the list will grow a thousand times quicker than mine. 😅 Sometimes talking about organic growth is comparing apples and oranges.

You're not only the nicest person but also super responsive. It is incredible what you're doing.

So what brought you to Buttondown?

I started playing around with Buttondown because a person chatted on Twitter and was vouching for you and your service, which is still exceptional. You're not only the nicest person but also super responsive. It is incredible what you're doing.

I think your personal approach is super valuable. It feels great not to be a ticket number in a ZenDesk queue.

I don't know how you do it, but if I need something or if there is a problem, you're back with me in 12 hours and we figure it out. I think this is what makes Buttondown stand out.

Your use of Buttondown — with building your own archives and so much custom frontend work — is unique. How does Buttondown fit into your CMS?

First off, my setup with Buttondown is weird. I only use three things:

  1. Your subscriber management
  2. Your email sending
  3. Your editor

It's like Buttondown in 'headless mode'. I publish and write things in Contentful; from there, I publish it to my blog. Then I have a little tool that transforms my Contentful Markup (I have some custom things on the blog) to Buttondown Markdown and I simply paste it into the editor.

I've got a custom layout that you enabled for me around a year ago, just to have a custom footer and header.

But overall, I think Buttondown does the job just fine. It is out of my way. I think the default styles work. The emoji handling works. I think everything works out of the box. I don't have many customizations.

What could Buttondown do to make your life easier, either in terms of publication or sending things out?

Analytics. I wish there was a bit more power in the analytics section because there's so much data in newsletters that is fun to poke around -- I like to open up my computer and look at the user. Even if there is one person overnight, I look at their overall stuff. I do that every day. So, a bit more power there dividing by week, month, by day, or something.

Beyond that, what I would definitely appreciate is if there would be in Buttondown, a quick way for me to get the CTR in ads. If I could set an attribute on a link, I could go to the overview page and say, "the CTR on this ad was 2%." That would be tremendously valuable.

What customers say about Buttondown

I made the transition from MailerLite and I have no regrets. I also like that Buttondown focuses on the essentials by design and keeps me grounded and centered on what really matters.
Arthur Cendrier
Author, Thoughtful Inquiry
Overall, Buttondown has been terrific to work with and I recommend them for anybody who's thinking of starting a newsletter or moving over like I did.
Andy Magnusson
Customer Engineering Leader
Wanna know how good Buttondown as a product experience is? I upgraded to Basic before sending the first email, and then upgraded again two days later.
Zak El Fassi
Founder, Zaigood Labs
Mailchimp lost me due to their inferior product and the nightmarish merry-go-around experience with their overseas support team. Buttondown won me over with their superior product and second to none customer service.
Sav Tripodi
CEO, Sanico Software
Your support is amazing and I deeply appreciate how available and helpful you are. I LOVE being able to turn tracking pixels off. I didn't even realize this was an option when I signed up and am SO HAPPY to not track people.
Andrea Mignolo
Method & Matter
I'm also impressed with how responsive you are, and how you directly answer customers. Makes it really clear that signing up for your service was a good decision.
Nicole Tietz-Sokolskaya
Software engineer and writer
Very happy with Buttondown, works smoothly, it's very configurable and I love the minimalist design of the UI. It makes me focus on my writing. Plus, I'm super happy to support independent software and I should mention - the support I receive whenever I have a question is warm and quick :)
Martina Pugliese
Data scientist and storyteller
I just tested the RSS to Email feature for one of my blogs and it was incredibly easy to set up. It took me about 30 mins to figure out the same feature in Mailchimp.
Nicolas Bernadowitsch
This long weekend I fulfilled a long-standing promise to myself to switch my RSS-to-email provider from Mailchimp to Buttondown, and it’s been such a great experience. It’s cheaper, more flexible, less cluttered, and it’s run by Justin Duke who is just delightful and answered a bunch of my questions over the weekend (even though I asked him to please not!).
Rian van der Merwe
Director of Product at PagerDuty
I've been wrangling half a dozen tools to get my stuff up and running recently, almost all of which had some hiccup. Buttondown had zero. It did everything I expected and needed the first time.
Catherine Cusick

I, like almost everyone else I've seen talk about Buttondown, am IMMENSELY happy and impressed with your customer service. It turns out we can have nice things, which is really refreshing.

Email makes the world go ‘round, and Buttondown is how I manage it all for my keyboard projects.
Tim van Damme
Founder, MVKB
It's a truth, that should be more universally acknowledged, that Buttondown is the best newsletter software. Simple, does exactly what it sets out to do, and reasonably priced.
Noel Welsh
Founder, Inner Product
Buttondown is the perfect fit for my headless newsletter use case. And I contacted support with some specific requests and Justin responded within 30 minutes with great answers and a nice pinch of charm.
Sam Roberts

Hands down the easiest way to run a newsletter - and the free version is generous!

With API and Markdown support, you can build workflows that make it so easy to write.

I’ve never enjoyed writing newsletters as much as I do with Buttondown.
Kevin Lewis
You Got This!
Buttondown remains the easiest thing I use regularly, and I am grateful for that.
It's a humble app doing a common job but with end users in mind.
Si Jobling
Engineering Manager
Buttondown has been an amazing experience for me. The service is constantly being improved and customer service is the best. My newsletter with Buttondown has grown from a fairly small list to over 15,000 subscribers, and it hasn't broken a sweat yet.
Cassidy Williams
CTO, Contenda
I switched over to Buttondown from Mailchimp because of the difficulty I had with Mailchimp's campaigns, so Buttondown's easy and user-friendly system has been a genuine breath of fresh air.
Jessi Eoin

You’ve truly built a great product that I feel good about using (vs a monopoly from our tech overlords).
2030 Camp
I love how personal Buttondown feels, especially compared to Mailchimp, Convertkit, and services like that.
Simen Strøm Braaten
This product has been exactly what I’ve needed!
Nathan Bird
Podcast host, Chattanooga Civics
It's already so refreshing compared to the mega companies.
Casey Watts
Author, Debugging Your Brain
Definitely will be using for the foreseeable future. It’s a great service and I feel well cared for. Thank you!
Phoebe Sinclair
I’m a sucker for elegant UI and I really love your site, but above that I think your product has so much value for so many different people. I’m not a coder, I’m only familiar with the bare basics, but I was able to figure out and utilise Buttondown quickly.
Claudia Nathan
Founder, The Repository
The killer feature for me: Buttondown will take an RSS feed then automatically slurp up the content (in their words) and then send it to our subscribers. Job done. They seem like a good company too, so I’d say this is a winner.
Andy Bell
Founder, Set Studio
As a recent user of Buttondown, they are super on the ball. A week ago I discovered a security vulnerability and reported it on Friday afternoon. They acknowledged and fixed it in under two hours. On a Friday night! Talk about going above and beyond for your users!
Predrag Gruevski
Principal Engineer, Kensho
Well may I just say your support experience is already approximately 1 billion times better than ConvertKit. Excited to be switching!
Michael J. Metts
Author, Writing is Designing
Privacy focused sending and sign up form; lets me focus on writing - editor is "just" markdown; simple, elegant design template looks like a blog post; the founder is amazing - he's helped with every question I've had, even outside of Buttondown.
Joe Masilotti
Founder, RailsDevs
We need more nice and professional services like yours on the web.
Tobias Horvath
Designer and developer
No one is paying me to say this, but I love @buttondown so far for my lil newsletter. It’s so smart, simple, and attractive (and to my knowledge, not actively anti-trans!). Customer service is also legitimately excellent.
Julie Kliegman
Copy chief, Sports Illustrated
I love it! It lets me breathe, not compete as I write with other writers.
Devin Kate Pope
Writer and editor
It’s a pleasure working with you. Thank you! (And what a contrast with Mailchimp, where I spent two weeks and a dozen of emails trying find out why our form goes down sometimes (only sometimes), and never really got a real answer.)
Anton Sotkov
Software Engineer, IA
Buttondown exemplifies how I wish most software worked, and I hope to achieve a similar thing with the software I develop in the future.
Matt Favero
Software engineer
It feels incomparably good to be able to email just like a guy named Justin when you have a @buttondown question 15 minutes before you’re about to blast a Geistlist email. (Not a guarantee but wow this guy is human-level good.)
Jacob Ford
Designer About Town
Enter Buttondown, Justin Duke’s lovely little newsletter tool. It’s small, elegant, and integrates well. And it is also eminently affordable.
Will Buckingham
Your settings page is a joy to use and everything about Buttondown makes me happy.
Gareth Jelley
Magazine editor
have been on Buttondown for ~18 months and I can't recommend it enough.
Elizabeth Minkel

You really do make ALL other customer service look terrible by comparison.
Chris Mead
Improv teacher
There is a caring person on the other side of this software, which is one of the things I like the most about Buttondown.
Keith Calder
Film & TV Producer
I’d also like to add that @buttondown is an absolute joy to use. Hats off, Justin!
Elliot Jay Stocks

Shoutout to @buttondown and @jmduke for building an amazing bootstrapped product for newsletters, all while being very open to feedback and connecting directly with customers 🙏 Easily one of the most enjoyable product experiences I've had.
Den Delimarsky
Head of Ecosystem, Netlify
if you are looking for "newsletter tool for hackers" i tentatively believe the answer is @buttondown full api, compose in markdown, good docs for setting up domain auth, simple subscribe form HTML that you style yourself (or not)
Brian David Hall
Author, Your Website Sucks
I really like @buttondown as a blogging platform, it has the simplicity of Substack but the corporate culture is less toxic.
Chad Loder
Extremism researcher
I worked with @buttondown and asked for some new payment support beyond the supporter single tier / pay-what-you-want options. Justin was great and built it in just a couple days.
Dan Hon
Author & consultant
I write nonfiction and I use @buttondown - indie, GREAT personal customer support, very nice default styling, all the options I want including ones to protect my readers' privacy
Sumana Harihareswara
Open source maintainer
I use @buttondown because it does exactly what I need (manage subscribers and send markdown emails), not more and not less 👍 As a bonus it's made by an indie dev which I love!
Max Stober
Founder, GraphCDN
If you’re considering running an email newsletter, or if you already run one and are considering a change of provider, I highly recommend @buttondownemail. Super-easy app, very fair pricing with a generous free tier, and exemplary support. 💯
Peter Gasston
Technologist and speaker
imo @buttondown is easily one of the best-designed services i’ve used in recent years, if you have a substack you should really consider switching!
Kabir Goel
Engineer, Cal
Thanks for getting me excited about email newsletters again.
Garrick van Buren
I'm very thrilled that I can just write in Markdown without having to deal with email builders and all that crap.
Parham Doustdar
Thanks again for all the help! You’ve really turned something super complex into something super easy – sending new issues is as simple as firing off a text message.
Kartik Chaturvedi
Thanks for creating a simple way for people who want to, like, put words in a hole and have it sent to people... I am just thankful that something just nice and human exists on the internet.
Emmanuel Quartey
I tried 3 other newsletter services today and I felt like wanting to rip my hair out. They were all painfully slow. I'm so glad I found Buttondown.
Mohamed Elbadwihi
I’ve found Buttondown to be a great fit for my workflow and have been delighted by all of Justin’s thoughtful features and improvements to the product.
Michael Lee
Like seriously, so many lovely little easter eggs in one could-be-boring service.
Alexandra Muck
I just switched over from Tinyletter and I'm really excited to have found a place to host my tiny newsletter that doesn't seem like it's assuming everyone sending newsletters is an email marketer / growth hacker.
Tessa Alexanian
I'm in love with the simplicity of Buttondown.
I’ve used similar tools in the past and Buttondown is by far the simplest to use and most promising.
Fabrizio Rinaldi
Thank you for creating such a simple and brilliant tool. I’ve just signed up and the experience has been smooth and painless (the docs are great too!)
Oliver Holms
As a developer who has hated every email system I've ever used this is so nice.
Drew Hornbein
I wish I still wrote a newsletter just so I could use buttondown again. It’s like that.
