If you're evaluating email marketing affiliate programs, the Sender.net Affiliate Program vs ConvertKit comparison is one of the most common decisions publishers face. Both platforms serve entrepreneurs, creators, and small businesses, but they approach affiliate compensation and program structure differently.
This guide breaks down the key differences to help you choose the right program for your audience and revenue goals.
Commission Comparison: 35% vs 30% Recurring
Both programs offer recurring commissions, meaning you earn every month a referred customer stays subscribed. This is more valuable than one-time payouts.
Head-to-Head Breakdown
| Metric | Sender.net | ConvertKit |
|---|---|---|
| Commission Rate | 35% recurring | 30% recurring |
| Cookie Window | 90 days | 60 days |
| Payment Frequency | Monthly | Monthly |
| Minimum Payout | ~$50 (varies) | $25 |
Real-World Earnings Example
Scenario: You send 1,000 clicks/month with a 5% conversion rate (50 customers).
Sender.net:
- Assume average customer pays $20/month
- 50 referrals × $20 × 35% = $350/month
- After 12 months of customer retention: $4,200 cumulative earnings
ConvertKit:
- Same 50 referrals at $20/month average
- 50 × $20 × 30% = $300/month
- After 12 months: $3,600 cumulative earnings
Difference: $50/month (+16.7%) in favor of Sender.net.
This gap widens as your referral volume increases and as referred customers stay subscribed longer.

Cookie Window: 90 Days vs 60 Days
A cookie window is how long after someone clicks your link they can still be attributed to you if they convert.
Sender.net: 90-Day Window
- Advantage: Captures browsers who take 2–3 months to research and decide
- Real impact: Many small business owners evaluate email platforms over 6–8 weeks before committing
- Your benefit: Higher conversion attribution, more recurring revenue
ConvertKit: 60-Day Window
- Still solid: Captures most purchase decisions made within 2 months
- Disadvantage: Misses conversions from users who bookmark your link and return after 60+ days
- Practical impact: ~10–15% fewer attributed conversions for slower-decision audiences
Winner: Sender.net, especially if you target B2B audiences or cost-conscious publishers who deliberate longer.

FAQ
1. Can I promote both programs simultaneously?
Yes. Nothing prevents you from promoting both Sender.net and ConvertKit. In fact, many publishers do this to:
- Diversify revenue (reduce platform dependency)
- Recommend the best tool for each audience segment
- A/B test messaging and conversion rates
However, avoid confusing audiences. Be transparent about why you recommend each tool for different use cases.
2. Which program pays out faster?
Both pay monthly, typically between the 1st and 15th of the following month. ConvertKit has a $25 minimum payout threshold; Sender.net's varies. Neither offers weekly payouts. Factor in 3–5 business days for bank transfers.
3. Do I need disclosure when promoting these affiliate programs?
Yes. Both Sender.net and ConvertKit require clear, conspicuous affiliate disclosures per FTC guidelines. This means:
- Adding "Affiliate Link" or "I earn a commission if you purchase via this link" near your recommendation
- Placing disclosures before people click, not buried at the end
Failure to disclose damages trust and violates regulations.
