On Popcall, you can send unlimited-length messages, but longer messages will be priced higher based on the number of characters you send (depending on the creator's settings). This helps make sure creators are incentivized to read and respond to long messages, as well as short ones.

For instance, if a creator has a price of $2.00 per message and a soft limit of 250 characters, your message will be priced as:

• Up to 250 characters = $2.00
• 251-500 characters = $4.00
• 501-750 characters = $6.00
• And so on

This only applies to the length of your sent message. You won’t be charged extra if creators send a long reply.
