Why Promote CMDK?

Industry-Leading Commission Structure

Earn 20% recurring commission for life on every paying customer you refer. Unlike most affiliate programs that cap commissions after 12-24 months, CMDK pays you for the entire customer lifetime.

What you earn:

  • Monthly plan ($9/month): $1.80/month per customer, every month they stay subscribed

  • Yearly plan ($79/year): $15.80/year per customer, recurring annually

  • Lifetime plan ($169 one-time): $33.80 one-time commission

Average affiliate earnings: Top affiliates earn approximately $250/month, with growth potential as your referrals compound over time.

Better Than Competitor Affiliate Programs

CMDK’s affiliate terms are significantly more attractive than other email productivity tools:

Tool Commission Duration Cookie Pricing
CMDK 20% recurring Lifetime 60 days $9-169
Superhuman No public program N/A N/A $30/month

Frequently Asked Questions

Do I need to be a CMDK user to promote it?
No, but we highly recommend using CMDK yourself so you can create authentic, experience-based content. We offer affiliate partners a free lifetime account.

Most conversions happen within 7-14 days of initial click, but the 60-day cookie window gives your referrals plenty of time to decide.

Can I promote CMDK via paid ads?
Yes! Google Ads, Facebook Ads, and other PPC platforms are allowed. However, you cannot bid on “CMDK” branded keywords.

If a customer requests a refund within their trial period or first 30 days, the commission will not be credited. This is standard across all affiliate programs.

Can I promote CMDK internationally?
Absolutely. CMDK works globally wherever Gmail is available. We pay affiliates worldwide via PayPal and Wise.
