## Why “Unlimited Contacts” on Free Plans Actually Matters
Most “free” plans are **free tiers with hidden limits**. You signup free, your list grows to 500 or 1,000 contacts, and then you’re blindsided with a **$30-50/month bill**.
### The Hidden Traps
**1. Contact Caps**
– Mailchimp: Free for 500 contacts → $26/mo for 2,500 contacts
– MailerLite: Free for 1,000 subscribers → $15/mo for 1,001+
– Klaviyo: Free for 250 contacts → $20/mo for unlimited
**2. Sending Limits (Even if Contacts Are Unlimited)**
– Brevo: Unlimited contacts, but only 300 emails/day free
– HubSpot: Unlimited contacts, but 2,000 emails/month free
– Systeme.io: Unlimited contacts, 2,000 emails/month free
### Systeme.io’s True Freemium Model
**Systeme.io is the only platform that’s truly freemium:**
– ✅ **Unlimited contacts forever** (no cap ever)
– ✅ **2,000 emails/month free** (generous for new marketers)
– ✅ **All core features included** (no locks on basic functionality)
– ✅ **Funnels, webinars, courses** included (not just email)
– ✅ **60% LIFETIME affiliate commission** (unmatched in the industry)

– **Webinar Plan ($97/mo):** 60% × $97 = **$58.20/month per referral, forever**
**Real-World Scenarios:**

Free plan includes:
– **500 contacts** — Capped (not unlimited)
– **1,000 emails/month** — 100 sends/day limit
– **Basic templates** — 100+ designs
**Reality check:** This is **not freemium** — it’s a 500-contact trial that forces you to pay after hitting the limit.
## Migration Guide: Moving from a Free Plan to Paid (Without Losing Data)

– From MailerLite: Contacts → Export → CSV
