The Mailbox contains items and frogs that have been either purchased, found in the pond or received as a gift. These include the following:
- Frogs purchased from the FrogMart.
- Frogs cloned with the Froggydex.
- Habitats purchased from the Supply Shop.
- Scenery purchased from the Supply Shop.
- Frogs, habitats, and scenery discovered in daily gifts.
- Frogs, habitats, and scenery discovered on The Pond.
- Gifts (including frogs or scenery) from other players.
- Frogs obtained via a Special Event.
The Mailbox can hold up to 8 items at one time. The time an item or frog takes to be delivered varies with the level of rarity. When an item is first shipped, it shows in the mailbox with a delivery time which counts down in real time. Stamps can be used to instantly deliver an item. The cost is 1 stamp per each 4 hours of delivery time remaining. Once an item has arrived it remains in the mailbox until it is either placed in a habitat or removed.
Mailbox with VIP Package[]
The VIP Package, in addition to several other features, affects the mailbox in two ways. It grants Express Mail which doubles the delivery speed of items in the Mailbox. It also increased the number of items a player can have in the Mailbox from 8 to 32.
Express Mailbox[]
The Express Mailbox was an in-app purchase that reduced all future delivery times by half. It was sold in the Pro Shop for $4.99. It is now part of the VIP package and no longer available by itself.
