Once a campaign email sends, every mistake in it is in every inbox on your list.
A dead link. A code that ended last week. A subject line that says 20% off when the code only gives 15%.
I built an n8n workflow that checks Klaviyo campaigns before they go out:
• Every hour it finds the campaigns scheduled for the next 24 hours, and checks each A/B version on its own.
• It tests the links and images in the email.
• Claude lists every code, discount and date it finds, with the exact words.
• Plain code checks those against a Google Sheet of your live offers and the send date. Anything Claude quotes that is not in the email is thrown out.
• Slack gets one message per email: ready, ready with notes, or what to fix. If a problem is still there close to send time, you get one reminder.
It only reads Klaviyo. It never edits, cancels or sends a campaign, so the fix stays in your hands.
If you send Klaviyo campaigns for your store or for clients, send me a message and I will set this up for you.

QuoteDesk: instant quotes for a cleaning company, and the follow-ups nobody has time to send.
A home cleaning business loses jobs in two places: quotes that take a day to come back, and open quotes nobody chases. QuoteDesk handles both for Maple & Mop, a demo company.
What runs on its own:
• Priced on the server. The client sees a live, itemized price; the saved total is recomputed from the owner's price list, never trusted from the browser, in integer cents.
• The quote is emailed the second it is saved, with a link to book or pick another slot.
• One follow-up, never two: an hourly job nudges quotes still open after 24 hours, stamps them so it can't fire twice, and skips anyone who booked.
• A day-before reminder for every booked cleaning, also sent once.
• AI reads the client's notes: "two cats, fourth-floor walk-up" becomes Pets and Stairs flags plus 30 extra minutes for the crew.
• Owner dashboard: quotes today, booking rate, expected revenue, bookings after a follow-up, a 7-day schedule and an email timeline per quote.
Owner actions require the Base44 admin login, checked on the server. Judges get a read-only demo view with masked emails: Owner login, then View the demo dashboard.
Stop writing emails and manually tracking follow-ups.
You can automate most of this with n8n and Google Sheets.
Here's how it works:
Add your leads to a Google Sheet.
Connect your Google Sheets and Gmail accounts to n8n.
Set up your email templates and follow-up rules.
Execute the workflow to create email drafts automatically.
Review each email and send it manually.
The workflow updates each lead's status, so you know who is ready for the next follow-up.
No need to create every email from scratch or track every follow-up manually.

Great automation idea! Saving time on drafting and tracking follow-ups lets you focus more on building relationships with leads. 🙌

Nice build, and good call putting a Structured Output Parser after Gemini. How do you keep the score itself stable from one run to the next? I'd split it into the reasons (company size, role, budget signal) as separate fields and compute the final number in a Code node, so the...
