1/ 🧵 Do bots inflate email click-through rates? Yes. But not nearly as much as they inflate open rates. In a prior analysis, we found roughly two-thirds of reported email opens were not generated by actual humans. Apple MPP, proxies, and security tools have made open rates wildly misleading.

2/ 🧵 Clicks are not nearly as broken. We reviewed several campaigns: Campaign 1 Reported CTR: 4.4% Likely real CTR: 3.9% Campaign 2 Reported CTR: 1.5% Likely real CTR: 1.3% So yes, about 11% of reported clicks looked like bots or security tools.

3/ 🧵 The annoying part: Klaviyo already has bot click filters, but they are turned off by default. We did this analysis using Klaviyo’s own bot click filters. Takeaways: Open rate: mostly broken CTR: imperfect, but still useful Revenue per recipient: best metric Don’t diagnose campaign performance from opens alone.

AI blew me away this weekend. My 2nd grader drew a book in page order, but we needed it rearranged for double-sided printing so normal letter paper could fold into a booklet. My wife took photocopies and manually put the pages in a booklet format. I took photos, gave them to ChatGPT, and asked: crop out the pages, straighten it out, read the story to figure out the correct order, and format it as a double sided print-ready PDF for saddle stitching. 11 minutes later, it worked.

Pity the billionaires. Thousands roaming the Earth, all looking like financial peasants compared to Elon’s net worth. With the gap only widening every day. 😂

Your 50% email open rate is likely closer to 18%. 💩 We analyzed Klaviyo campaign data and found roughly two-thirds of "opens" were Apple Mail Privacy Protection, proxies, or security tools: not actual people opening your email. 🧵

The numbers are stark. Campaign A: Klaviyo reported 34.36% open rate. Real human open rate after filtering bots: 11.68%. Campaign B: reported 48.44%. Real rate: 17.62%. Both nearly 3x inflated. And Klaviyo's bot filter exists, it's just turned off by default.

Important nuance: a fake open ≠ a fake contact. The person is real, they just didn't open it. A proxy or security tool did it on their behalf. If open rates look great but revenue per recipient is flat, don't trust the open rate. Watch CTR and more importantly, revenue/recipient instead.

🧵 Most DTC brands are still using AI as a copywriting tool. The leaders are using agents, MCPs, Skills, and Connectors to automate reporting, audience building, creative production, and full-funnel execution. That gap is getting wider.

1/ Most Klaviyo agencies don’t need more AI content prompts. They need a way to turn their best strategist’s workflow into something the whole team can run. That’s the real problem when you’re managing 10, 20, or 50 Klaviyo clients.

3/ So we published the Claude Klaviyo Deliverability Guide for agencies. It includes 14 copy-paste prompts for: → Engagement segmentation → List hygiene → Re-engagement flows → Deliverability diagnostics → Campaign send strategy → Client-ready analysis

4/ These are not “write me a subject line” prompts. They are the workflows your senior email strategist runs in their head, written down so your whole team can run them. For agencies managing Klaviyo for 10 clients, this helps scale deliverability work without adding headcount. Read the full guide grab all 14 prompts here → customers.ai/guides/claude-k…

Elon's post is a nod to the South Park "Underpants Gnomes" meme, where their plan is: 1. Collect underpants, 2. ?, 3. Profit. Here, it's about AI: Buy tons of GPUs (for training models), skip the details, and profit. Likely poking fun at xAI's ambitious goals!

The Spencer Pratt campaign offers an explosive template for any outsider or change candidate running for elected office: Challenge the status quo. Stay on message. Relentlessly speak truth to power. Good luck, Angelenos. I wish we had a common-sense candidate like this in my home town of Cambridge, Massachusetts where murderous shooters run amok in the streets.
To my fellow Angelenos who want change, and are considering voting for Nithya Raman, I can assure you, she is not fit for the job, and she has no path to victory. A vote for Nithya is a vote for Karen Bass. I am ready to earn your vote and make LA feel safe for all.

1/ I bought Klaviyo stock on May 7 when it was crashing. Not because I think every SaaS company is magically going back to 2021 valuations. But because I don’t buy the “SaaSpocalypse” narrative either.

7/ My view: SaaS is not dead. Bad SaaS is dead. Efficient, embedded, revenue-driving SaaS still has a lot of room to run.
