Make the next email matter.
Marketer Tips turns Chase Dimond’s email marketing experience into lessons you can use before the next send. Its real subject is what happens after someone gives you their attention.
CustomersAI and the expensive art of recognizing a stranger
Larry Kim built a business around finding customers. Its most revealing turn came when he started asking whether the names it found belonged to the right people.
The Checkbox That Became a Business
Dataships began with a privacy tool that customers barely noticed. It found its market when the founders asked a more pointed question: what happens to a paying customer after the checkout box is ticked - or missed?
The Boston Agency That Spent 27 Years Building Trust - Then Bought Five Companies in Two Years
For 27 years Verndale sold one thing: the platform build nobody else wanted to own. Then a Dallas buyout firm handed it a checkbook - and a Boston services shop turned into a roll-up.
The Agency That Named Itself BAD - and Made Good Brands Go Bad
A Georgia agency built a brand around a word every marketer is trained to avoid. Behind the joke is a 150-person shop managing a quarter-billion dollars in ad spend.
Revamp (YC S23)
Revamp is a San Francisco startup (YC Summer 2023) that builds AI agents for eCommerce retention marketing. It plugs into Klaviyo and Shopify to turn scattered customer data into smart segments and then writes genuinely 1:1 personalized emails - drawing on signals like location, weather, purchase history and browsing behavior - so D2C brands can lift email revenue without hiring an army of copywriters.
Polar Analytics
Polar Analytics is a multichannel AI analytics platform for ecommerce and direct-to-consumer brands, built to unify scattered marketing, sales and CRM data into one dashboard on top of a warehouse-native data stack. Founded in 2021 by David Dokes and Charbel Seif, it centralizes 45+ data sources, tracks metrics like CAC, ROAS, MER and LTV, and layers AI agents and a Model Context Protocol connector so merchants can query live data and act on it. Polar serves 4,000+ brands across 45 countries and has raised roughly $28.5M, including an $18M Series A led by Chalfen Ventures in November 2024.
Maverick
Maverick is a San Francisco AI startup that generates personalized videos at scale for ecommerce brands. A merchant records one short base video, and Maverick's generative AI clones the voice and reshapes it to greet each customer by name across email flows - welcome, post-purchase, abandoned cart and more. The platform layers on inbox-placement optimization and automatic subject-line A/B testing, and plugs natively into Klaviyo. Founded in 2021 by Eitan Winer and Debarshi Chaudhuri, Maverick sells the idea that online shopping should feel a little more like being recognized by name at your neighborhood store.
Zaymo
Zaymo is a YC W24-backed B2B SaaS company based in Lehi, Utah that turns static marketing emails into interactive mini-apps. Built on AMP for Email technology and deeply integrated with Klaviyo and Shopify, Zaymo lets ecommerce brands embed one-click purchasing, subscription management, review collection, and gamified elements directly inside the inbox — no redirect required. Customers report 12–15X ROI, 24–52% reductions in subscription churn, and conversion lifts that static email simply cannot match.
