Letterhead Gotchas & Operational Limits
These are documented constraints or practical friction points that may matter before you adopt the product.
Pricing depends on newsletter count and audience size.
A team cannot determine its subscription cost from a public price list alone.
Evidence source ↗The public G2 review set is small and older than the current product pages.
