Meta quietly added 2-5% "location fees" to ad delivery in the UK, France, Italy, Spain, Austria and Türkiye this month.

Billed outside your budget, as a separate invoice line.

Check July's invoice before you blame the creative.

Remember folks, new free-tier Supabase projects can no longer customize auth email templates.

Anti-phishing move. Fair enough.

But if your onboarding emails suddenly look default and ugly, that's why.

Upgrade the project or route auth mail through your own SMTP.

In case you didn't know: Google published its own guide on ranking in AI search.

The short version? It's just SEO. Same ranking systems, same best practices..

And that llms.txt file everyone tells you to add? Google says they don't even read it.

Save your money before some "GEO expert" charges you $2k for a markdown file.

Half of this week's Product Hunt leaderboard is tools FOR agents, not AI tools for humans.

Structured search for agents. Social listening for agents. An iPhone remote for your coding agent.

We spent 20 years building software for humans, then 2 years teaching agents to use it. Now we're skipping the humans entirely.

What's the first tool you'd build for an audience of agents? 🧙‍♂️

43 cold emails. 17 replies. 1 customer.

A founder posted these numbers and everyone dunked on the 1.

Wrong takeaway. A 40% reply rate means the list and the message work, the offer doesn't. That is the cheapest fix in the whole funnel.

What reply rate do you get on cold outreach?

Meta is quietly removing the setting that let users disconnect their off-platform activity from their ad profile. Rolling out in the US now.

What it means for you:
- retargeting pools get bigger without you lifting a finger - attribution signal improves
- lookalikes get stronger

Refresh your 30/60/90 day audiences and watch August CPMs. Free upgrade if you catch it early.

Running two products solo means every week one of them thinks you abandoned it.!

This week Younger app got the love:

We shipped animations for exercise mode, activation checklist, warm up feature and many small UI fixes plus we tested 4 hypothesis on Meta ads.

@NavoHQ is staring at me from the other monitor...

How do you split your week when you run more than one thing?

[Chris @BuiltWithChris]

An open model called Kimi K3 pulled 1,600+ points on Hacker News today. Same week, LM Studio shipped an agent runner for open models.

The local agent stack is assembling itself in real time.

Serious question: is anyone running production agent workloads on open models, or are we all still on API credits like me?

In case you didn't know: Google Play quietly stopped eating chargeback costs.

Developers pay for most chargeback losses now. A Review Refund API launched July 1 so you can contest fraud with delivery and consumption evidence.

For a small app, a few chargebacks is the difference between a green day and a red one.

Google calls this "industry standard".

@tinkerersanky World of Warcraft 😅

How marketing targets low confidence:

Invents a flaw 🔍
Triggers FOMO 📉
Sells the "magic fix" 🪄

This toxic trio turns your insecurity into their profit. First they make you doubt yourself, then they isolate you, and finally they make you pay to feel better. Spot the loop.

We closed month one of sales with almost $300 MRR, but the knowledge we gained is worth much more. Month two, here we come!

When starting work on a new feature, always begin with a Feature Requirements Document. This document should clearly define:

- What the feature is about
- How the feature improves the user experience
- Edge cases that should be considered
- Any additional context, assumptions, risks, or implementation notes that are valuable

Only after the Feature Requirements Document is completed and reviewed should development begin.

In case you didn't know: In order to contact users that use Apple’s private email relay service, you must register email sources that your organization will use for communication.

if useris using apple's option hide my email when signing up for your app, and you didn't do this, your marketing emails are not reaching that user

Our Younger Fitness App for Midlife is getting some traction 🙌

[Chris @BuiltWithChris]

Marking the milestone where we rebranded Younger into a premium midlife companion helping women 45+ get unstuck and synchronized our official launch across Meta and Google Ads

Let the games begin
