Klaviyo Review: AI-Powered Email Marketing Platform for Online Stores

When a Shopify store outgrows basic Mailchimp campaigns and starts losing money on unconverted customers — the owner usually googles “email marketing for ecommerce.” And Klaviyo will be the first link recommended by peers in the industry. Here’s why.

Klaviyo isn’t just a newsletter service. It’s a B2C CRM platform built specifically for online stores. It collects customer data, analyzes their behavior, and launches personalized campaigns through email, SMS, WhatsApp, RCS, and push notifications to mobile apps.

Mailchimp Review: Email Marketing & Automation — Features, Pricing & Affiliate Program

Sat, 01 Aug 2026 00:00:00 +0000

Mailchimp’s story is a story of evolution. First, a tiny email newsletter service with a monkey logo. Then — a $12B exit to Intuit. And in 2026 — a full-fledged marketing platform sending 600+ million emails daily. But has the monkey kept its soul? And is Mailchimp worth the money when dozens of cheaper competitors surround it? Here’s the honest take.

Website: mailchimp.com

Where It All Started

In 2001, Ben Chestnut and Mark Armstrong launched an email newsletter service as a side project of their web agency. The name Mailchimp — a play on “Chimp,” with the famous monkey logo named Freddie von Chimpenheimer III drawn for $30. In 2021, Intuit acquired the company for $12B — the largest deal in marketing SaaS history. Today Mailchimp is 14M+ users, an AI campaign optimization engine, and deep integration with the Intuit ecosystem (QuickBooks, TurboTax).

Mon, 06 Jul 2026 00:00:00 +0000

Brevo is the rebranded Sendinblue. The name change happened in 2023 and caused some head-scratching at first, but the product didn’t suffer from the rebrand. It’s a platform for email campaigns, SMS marketing, chat, and CRM. A direct competitor to Mailchimp, but with more sensible pricing.

The Affiliate Program

Brevo offers two formats:

Refer a Friend — a one-time €10 payment per sign-up. The user must verify their email and send their first campaign. Nothing to write home about, but fine for high-volume traffic.

Three questions about money

How much do they pay? Two options. Either $100 fixed per sale, or 33% recurring commission — every month as long as the client pays. At an average plan of $49/month, recurring brings ~$16/month per client. After six months, recurring overtakes fixed.

ConvertKit Affiliate: Honest Money Talk

ConvertKit is an email service built for creators, bloggers, and info-businesses. Their affiliate program is simple and straightforward: 30% recurring commission for two years on every referred client.

What this means in practice: you refer someone on a $25/month plan — you get $7.50 every month. Referred 100 people? That’s $750 monthly. For 24 months straight.

Payouts through PartnerStack, threshold — $25. A small but nice touch — you don’t need to accumulate $100 like in many other programs.
