Features That Matter For Affiliates
- Affiliate-link tolerance — won't flag your account
- Tagging + segmentation — for email sequence triggering
- Landing page builder — saves needing a separate tool
- Deliverability reputation — gets emails into the inbox, not spam
- Automation rules — trigger sequences based on behavior
My Recommendation
Start with AWeber free tier if you'll promote OLSP — it's the platform OLSP integrates with and uses on its own optin forms. If you're brand-agnostic, ConvertKit free has the cleanest UX. Beehiiv is the dark horse for content + email combo.

Frequently Asked Questions

Best free email tool?
AWeber or ConvertKit free tier. Both handle affiliate links fine up to ~500-1000 subs.
When should I upgrade to paid?
When you hit the free tier subscriber limit AND your list is generating revenue.
Do I need landing pages too?
Most email tools include simple landing pages. If you need advanced, look at Systeme.io or ClickFunnels.
What about deliverability?
