Messenger allows unlimited, free-flowing conversations between members, all for 1 credit per conversation.
This means you can message back and forth with one member for as long as you want and only use up one credit, and unlike some other dating sites your conversations do not expire.
The number of messages you can send depends on your Premium membership level.
Silver members start 4 new conversations per day
Gold members start 12 new conversations per day
Platinum members start 25 new conversations per day
NOTE: You can only send a maximum of 3 messages to a member when starting a new conversation before they reply to you. Once they reply there is no limit to the number of messages you can send to each other.
