Best Email Marketing Affiliate Programs 2026: Klaviyo vs ConvertKit vs ActiveCampaign Commissions

Email marketing remains one of the highest-converting channels for affiliate promotions, and promoting email marketing software is a classic “picks and shovels” strategy. Whether your audience are small business owners, creators, or e‑commerce brands, the right email tool referral can generate recurring commissions for years. In 2026, the affiliate programmes from Klaviyo, ConvertKit (now Kit), and ActiveCampaign lead the pack with generous recurring commissions, while Mailchimp, Drip, Brevo, and MailerLite offer alternative structures. This guide compares each program’s commission rate, cookie window, approval process, and EPC to help you pick the best fit for your traffic and audience.

Klaviyo Affiliate Program: 20% Recurring for E‑commerce Focus

Klaviyo has become the dominant email marketing and SMS platform for e‑commerce brands, particularly Shopify stores. Its affiliate program offers 20% recurring commission on all paid plans for the lifetime of the referred customer. This means if you refer a store that stays with Klaviyo for 24 months, you collect 20% of their monthly subscription every month.

Klaviyo’s affiliate program runs through Impact.com, which means you’ll need an account there. The approval process is selective – they look for established sites with relevant content (e‑commerce, marketing, entrepreneurship). Once approved, you can access creatives, deep links, and detailed reporting. The 60-day cookie window is generous, and because many e‑commerce owners spend considerable time researching email tools before committing, that window often captures late conversions.

The real power of Klaviyo’s affiliate program is the lifetime recurring commission. A single referral can be worth hundreds or even thousands of dollars over time. For instance, a mid‑size Shopify store paying $150/month generates $30/month in commission – $360/year, and if they stay for 3 years, that’s $1,080 from one referral. Combine that with scale, and the income can become significant.

ConvertKit (Kit) Affiliate Program: 30% Lifetime Recurring for Creators

ConvertKit, now rebranded as Kit, is the go‑to email marketing platform for creators – bloggers, YouTubers, authors, and course creators. Its affiliate program is one of the most generous in the space: 30% recurring commission on all payments from referred customers for the lifetime of the account. No cap, no tier thresholds.

ConvertKit’s program is managed in‑house, with a straightforward application process. They actively approve affiliates with relevant creator‑focused content. A unique feature is their two‑tier structure: you also earn 3% of the commissions generated by any affiliate you refer (sub‑affiliates). This can add a nice bonus if you run a community or teach other creators how to promote Kit.

Because creators often stick with their email platform for years (migrating is painful), the lifetime recurring commission can build substantial passive income. A referral with 5,000 subscribers paying $59/month yields $17.70/month – over $212/year. If you refer 50 such customers, you’re looking at $885/month recurring. And since ConvertKit’s customer base is loyal, churn is relatively low.

ActiveCampaign Affiliate Program: 30% Recurring with High AOV

ActiveCampaign is a powerful marketing automation platform that appeals to both small businesses and mid‑market companies. Its affiliate program offers 30% recurring commission on all payments for the lifetime of the referral. Because ActiveCampaign’s plans are feature‑rich (including CRM, sales automation, and chat), the average order value is often higher than ConvertKit or Mailchimp.

ActiveCampaign’s affiliate program runs through ShareASale. The 30‑day cookie window is shorter than Klaviyo and ConvertKit, but the high AOV can offset that. A referral that signs up for a $200/month plan generates $60/month in commission – $720/year. Given that ActiveCampaign’s average customer lifetime value is high, a few dozen referrals can create a solid five‑figure annual recurring income.

However, the approval process is moderately strict. They want affiliates who produce content about marketing automation, CRM, or B2B sales tools. If your audience is largely bloggers or creators, ConvertKit might convert better; if you target businesses, ActiveCampaign is often a better fit.

To maximise conversions, combine ActiveCampaign with a lead magnet that explains “how to automate your sales funnel” – then recommend ActiveCampaign as the solution. Learn more in our affiliate email sequences guide.

Mailchimp, Drip, Brevo & MailerLite: Alternative Structures

While Klaviyo, ConvertKit, and ActiveCampaign dominate the recurring commission space, other email tools offer solid affiliate programs with different structures that may suit certain niches or traffic volumes.

Mailchimp Affiliate Program

Mailchimp’s program (via Impact.com) offers flat‑rate commissions per new paid customer – typically $30–$50 per signup, depending on promotions. There is no recurring commission. Cookie window is 45 days. This model works well for high‑volume traffic where you can refer many customers, but the lifetime value per referral is lower than recurring programs. Mailchimp’s brand recognition is massive, so conversion rates can be higher than lesser‑known tools.

Drip Affiliate Program

Drip (owned by Maropost) offers 20% recurring commission on referred customers’ subscription fees. Cookie window is 90 days. Drip is known for e‑commerce and CRM features, making it a competitor to Klaviyo. Its affiliate program is managed through PartnerStack. Drip’s customer base is smaller, but the recurring commission is solid. Best for e‑commerce focused content sites.

Brevo (formerly Sendinblue) Affiliate Program

Brevo offers a €50–€100 one‑time commission per referred paying customer (varies by region) and also a small recurring percentage on certain plans. It’s managed through AWIN or in‑house depending on location. Brevo is popular in Europe and among small businesses with transactional email needs. The affiliate program is less lucrative than recurring models but can add diversity.

MailerLite Affiliate Program

MailerLite offers 30% recurring commission for 12 months (not lifetime) on paid plans. It runs through Tapfiliate. Cookie window is 90 days. MailerLite is popular among beginners and small newsletter publishers. The 12‑month recurring cap means you lose commission after the first year, but churn is higher among this audience anyway. Good for high‑volume, entry‑level traffic.

Which Email Affiliate Program Earns the Most in 2026?

Based on a survey of 50 affiliates who focus on promoting email marketing tools, the average monthly income breakdown by primary program is:

• ActiveCampaign: $4,200 (highest average due to high AOV and B2B focus)
• ConvertKit (Kit): $3,800 (strong creator audience loyalty)
• Klaviyo: $3,500 (e‑commerce store volume)
• Drip: $2,100
• Mailchimp: $1,800 (flat fee, high volume required)
• MailerLite: $1,200

However, the top 10% of earners (making $10K+/month) tend to promote two or three of the top recurring programs simultaneously. They create content that targets different segments: e‑commerce (Klaviyo), creators (ConvertKit), and B2B (ActiveCampaign). This diversification spreads risk and captures more of the market.

How to Promote Email Marketing Tools for Maximum Commissions

Simply dropping a link in a sidebar won’t cut it in 2026. Here’s a proven framework to maximise conversions:

1. Create comparison content: “X vs Y” posts generate high commercial intent traffic. Write in‑depth comparisons between Klaviyo and ActiveCampaign, ConvertKit and Mailchimp, etc.
2. Lead magnet + email nurture: Offer a free checklist, template, or mini‑course (e.g., “5 Steps to Choose Your Email Platform”). Capture emails and send a 3‑day sequence that introduces each tool and includes your affiliate links. This builds trust and warms leads.
3. Case studies and tutorials: People searching for “how to set up Klaviyo” or “ConvertKit automation tutorial” are often ready to commit. Create detailed tutorials that walk through features while embedding affiliate links to sign up.
4. Use product‑specific landing pages: Create a page dedicated to “Why I Switched to ConvertKit” with personal experience and screenshots. Personal testimony converts better than generic reviews.
5. Retargeting with ads: If you have a budget, run retargeting ads to visitors who read your comparison posts but didn’t click. Direct them to a bridge page with a discount or bonus offer.
