Questions
- What's the best email tool for an early-stage startup?
- If you mainly email users about product changes — not run automation — day3 keeps costs flat as the list grows. Subscribers are unlimited on every plan.
- Will day3 get more expensive as we grow?
- Only if you send more. Adding subscribers never raises the bill — day3 prices by sends, not list size.
