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.

What Klaviyo Actually Is

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. By early 2026, the platform serves over 196,000 brands across 100+ countries, processes 2.5 billion events daily, and stores 7.3 billion customer profiles.

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).

Mailchimp vs Beehiiv: Two Generations of Email Platforms

Mailchimp is a veteran (2001) that evolved into a marketing ecosystem. Beehiiv is a newcomer (2021) that reinvented email newsletters for creators.

Let’s analyze from an entrepreneur’s perspective — someone who wants to send emails and earn money.

Mailgun vs SendGrid: Email API for Developers in 2026

Sun, 12 Jul 2026 00:00:00 +0000

Mailgun and SendGrid are the two titans of the email API market. Both send billions of emails per month. Both are used by GitHub, Uber, and tens of thousands of developers. But when it comes time to choose, the nuances start to matter.

Websites: mailgun.com and sendgrid.com

Pricing: Which Is Cheaper

No need to do the math — here’s the table for 50,000 emails/month:

Mailgun Foundation: $35/mo, dedicated IP included, email validation — 5,000 checks
SendGrid Essentials: $19.95/mo, dedicated IP — separate ($29.95/mo), email validation — separate

SendGrid is cheaper at entry ($20 vs $35), but as soon as you need a dedicated IP (and you do for proper deliverability), the price jumps to $50/mo. Mailgun includes the IP in the base plan.

Mailgun: Sending Email from Code Without the Pain

Sun, 12 Jul 2026 00:00:00 +0000

Mailgun is the granddaddy of email APIs. Launched in 2010, bought by Rackspace, then sold to Sinch. GitHub, Slack, Stripe, and Udemy send email through it. Nearly two decades on the market and billions of emails — they know everything there is to know about deliverability.

What It Can Do

The main thing — sending transactional emails: registration confirmations, password resets, payment notifications, alerts. Everything that must arrive instantly and reliably.

Brevo (Sendinblue): An Honest Look at the Email Service Affiliate Program

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.

ConvertKit vs AWeber: Affiliate Programs for Creators

Sun, 05 Jul 2026 00:00:00 +0000

ConvertKit and AWeber — two email services with similar rates but completely different audiences. For an affiliate, the choice between them matters more than it may seem.

The Money

Both programs pay a 30% recurring commission. On paper — identical. In practice — the difference lies in the client’s bill. The average ConvertKit client pays $29–79/month; AWeber, $19–49/month. So you will earn more per client with ConvertKit.

But AWeber compensates with a lower barrier to entry for the user — the click-to-trial conversion rate is often higher with AWeber.

GetResponse vs ActiveCampaign: Which One Should an Affiliate Choose in 2026

Sun, 05 Jul 2026 00:00:00 +0000

Both platforms are heavyweights in email marketing. Both have affiliate programs. But for an affiliate, there are differences between them — and they go beyond the numbers.

Commissions

GetResponse pays 33% recurring. Or $100 per sale as a one-time flat rate. Pick the model that suits you best. Recurring gives you passive income; flat rate means fast cash right here and now.

ActiveCampaign offers 20–30% recurring. The starting rate is lower, but the ceiling for top partners is comparable. There is no flat-rate option.

GetResponse Affiliate Program: Review

Fri, 03 Jul 2026 00:00:00 +0000

GetResponse: Affiliate Program with Recurring Commissions

GetResponse is a platform for email marketing, webinars, landing pages, and automation. Operating since 1998, serving 350,000+ clients in 183 countries.

Affiliate program sign-up: getresponse.com.

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

Thu, 02 Jul 2026 00:00:00 +0000

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.
