Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Lago

Free tier limited to 10,000 entities per month with 5M event cap
No specific pricing published for Pro annual plan or Scale plan
Self-hosted and on-premise deployments require engineering resources
Community support only on free tier
Scale plan requires annual contracts and sales engagement

Mailchimp

The free plan allows 250 contacts and 500 sends a month, with a 250 daily cap
Price is driven by contact count, so the list growing raises the bill regardless of how much you send
Send allowances are a multiple of contacts, 10x on Essentials and 12x on Standard, so a large list with heavy sending forces a tier change
Essentials allows 3 seats and Standard 5; unlimited seats need Premium at $350 a month
The headline $13 and $20 prices are for 500 contacts, not a flat rate
