It’s never too late to admit you made a mistake. It’s more powerful to admit a mistake, than to persist when everyone else knows it’s a mistake. It’s a mistake either way, but only one way means you’re either oblivious or disingenuous.

Yesterday has been crazy, stressful, and an emotional roller coaster. The joys of being an entrepreneur 🎢 Still, I’m glad that for the most part, we’ve built a company that we enjoy working at, despite the challenges thrown at us regularly 🤗

Every schema constraint you skip becomes an if statement in six places, and one of them will be missing. Put it in the database where it cannot be forgotten. #RubyOnRails #Rails #PostgreSQL

Selling an ESP is like selling a mattress. A mattress is bulky, hard to replace, essential for your sleep. It's unlikely you'll rave about your mattress or post about it on social media. Replacing a mattress won't make you sexy/healthy/rich. It's just a mattress. It's just an ESP.

Here's exactly why consultants are paid to do their thing. Only a fraction of SaaS companies have dedication, resources, and knowledge to expand their lifecycle marketing in a systemic way. Also, who makes comments this long and awesome?

Did you know that the Split Test node isn't just for A/B tests? It's a random group generator, splitting users into up to 5 paths at whatever percentages you choose. Split testing is the obvious use: create different user journeys, then compare using email metrics or conversion goals. Classic.

As a metalhead who likes to play the drums (but is intermediate level… at best), most of the music I love and listen to is way too hard for me to play 😩 This week I stumbled upon transcription for Since U Been Gone by Kelly Clarkson, and I'm having way too much fun with it than I care to admit 🤣

This January we offered a review call to all paying customers, and most people who replied were newly added team members. They didn't know much about @userlist.com, or what's happening in their accounts. This blew our mind. So we set up a simple workflow (took me 15 minutes).

"Now that I have user onboarding in place, what else can I do?" Your best next step is: a workflow for your paying customers. It runs at a slow pace (every 1-2 weeks) and combines educational content, feature nudges, and customer loyalty interventions (asking for referrals, reviews, etc).

Software companies overthink email marketing in the same way we overthink social media. A single post won’t impact your LinkedIn account. A hundred of them might. A single email won’t impact your growth. A hundred of them might. Zero emails… Safe bet. #bdtpblurbs #emailmarketing

My co-founder @uibreakfast.com and I are "recovering perfectionists". To remind us to not chase perfection for forever, we established "Better Done Than Perfect" as our mantra. It went as far as naming our podcast after it, creating merch with the slogan on it, and her getting a "b.d.t.p." tattoo.

When writing classes in Ruby, I've always been leaning towards minimal interfaces, and exposing as little as internal state as possible 🔒 This week, for the first time in my 20+ year career of writing Ruby, I went a bit further and changed a class to freeze itself after initialization 🧊

see indie hackers make this mistake all the time. The advice is: solve your own problem, then find more people like you. The problem? You probably wouldn't pay $50/month to solve that problem, so people like you probably won't either.

On the last episode of Slow & Steady, I talked about why it's important to remind people of who you are when emailing your list after being quiet for a while. People will just forget you. Quickly. You have to be very explicit to help them remember.

Time delays in @userlist.com now support advanced calendar settings. E.g. the 10th of the month, the first Monday, or the second Tuesday in March. Now you can send messages related to billing cycles, monthly check-ins, or annual reminders landing on a specific day. Give it a try in your workflows.

Small but useful @userlist.com update from @benediktdeicke.com. You can now edit user (and company) properties manually from the profile page. Previously, this was done via integration sync. With this, Userlist can cover more of your CRM workflow, with custom fields editable on the spot. Woot 🙌

We're currently working on getting full WYSIWYG to our message editor, so it actually renders the email inside the selected theme while editing the content, not just when previewing 💅 There have been a few challenges, but we're close to getting it shipped. And it's a massive step in terms of UX 🤯

A couple of things I wish we'd have done differently in Userlist's codebase: Allow accounts to have multiple workspaces, enforcing data types on data ingestion, and partitioning a couple of our largest stables right away 🙈 I'm sure we'll get to all of them eventually, it's just a lot harder now 😬

I finally figured out what caused this 🥳 We have a test helper to temporarily change translations. It was implemented by switching the I18n backend and resetting it afterwards. Turns out the backend is cached somewhere internally, so it was leaking outside of the tests that used it.
Original Implementation

def with_translations(locale, translations)
  original_backend = I18n.backend

  I18n.backend = I18n::Backend::KeyValue.new({}, true)
  I18n.backend.store_translations locale, translations

  yield
ensure
  I18n.backend = original_backend
endNew Implementation

def with_translations(locale, translations)
  I18n.backend.eager_load!
  I18n.backend.store_translations(locale, translations)



  yield
ensure
  I18n.reload!
end
