Hey there👋,

November's here (yep, it=E2=80=99s that time of the= year already), and we've got updates. We added search to our developer doc= s, Woorise shared how Postmark became part of their core infrastructure (th= eir words, not ours), and we found some solid reads on platform engineering= , API security (our own 🙂), and the most important API trends of 20= 25.=20

=E2=8C=98 + K

We've added search functionality to the Postmark de= veloper documentation, so you can quickly locate the exact API endpoint, co= de example, or integration guide you're looking for. Whether you're setting= up your first integration or troubleshooting a specific feature, just type= your question and get straight to the answer. Check it out at postmarkapp.com/developer= and let us know what you think.

We also added an llms.txt file

Want to know what Postmark does, fast? We created a= n llms.tx= t file that gives AI assistants a quick rundown of our product, feature= s, and how we're different from other email services. Think of it as a chea= t sheet for your favorite LLM when you're asking questions about transactio= nal email or trying to figure out if Postmark fits your project.

>Customer spotlight

You know you have to add a customer story to the ne= wsletter when someone says to you "Postmark has become part of our core= infrastructure".

Woorise, a SaaS platform that helps businesses of a= ll sizes generate leads and grow revenue, was tired of watching their custo= mers' critical emails=E2=80=94giveaway notifications, payment confirmations= , lead capture forms=E2=80=94get delayed or land in spam. For a platform se= nding thousands of emails monthly, unreliable delivery wasn't just frustrat= ing, it was breaking trust. So they made a change.

After switching to Postmark, Woorise saw results im= mediately: "Emails that used to take minutes =E2=80=94 or occasionally much= longer =E2=80=94 now land in inboxes in seconds," says Founder Christ= opher Vasiliou.

"Our support tickets about missing emails dropped t= o almost zero. We went from worrying about deliverability to trusting that = every critical email will arrive quickly and reliably." =20

Built something cool with Postmark lately?
We'd= love to feature you in our Customer Spotlight!

>Our latest, greatest finds from around the web

Here are three pieces that caught our attention thi= s month - each tackling a different aspect of how developers and infrastruc= ture are evolving:

Platform Engineering Hits the Boardroom (But Nobody Can Find Anything= ) - Platform engineering is now a C-suite priority, but here's= the irony: all those shiny Internal Developer Platforms meant to reduce co= gnitive load are actually making developers' brains hurt more thanks to too= l fragmentation. Oops.

Lock Down Your Email Inf= rastructure (Before Someone Else Does) - A practical guide on = securing your transactional email setup - from enabling two-factor authenti= cation to managing API tokens and monitoring activity logs. The best time t= o think about security is before you need to, not after. Consider this your= friendly reminder to audit those API keys sitting in your repos.

APIs Finally Get Bouncers (And They're Powered by AI) - Bro= ken authorization is still the #1 API vulnerability, so teams are outsourci= ng the headache to systems like Open Policy Agent. Meanwhile, passkeys are = finally ready to kill off passwords for good. RIP "Password123!"

Keep building amazing things,
