Why are contacts unlimited?
Because storing an address isn't the product. You pay for what you send, so keeping your full history costs nothing.
- No reason to delete old contacts to stay under a limit.
- Segments stay honest because the record stays complete.
- Engagement history survives log clean-up. A contact's counts never shrink.
- Free includes unlimited contacts too.
