# Mailbox

> Understand mailbox as a shared delivery concept across Forge products.

A mailbox is the sending and receiving identity used for outbound execution and reply handling.

Across Forge products, mailbox setup and health directly affect delivery quality and campaign stability.

## Why mailbox matters

* Mailboxes are tied to sender identity and reputation.
* Sequence execution depends on valid mailbox assignment.
* Warmup and placement behavior affect inbox outcomes.

## Mailbox across Forge products

| Product area             | Typical mailbox usage                                     |
| ------------------------ | --------------------------------------------------------- |
| Salesforge               | Use mailboxes for sequence sending and reply workflows    |
| Primeforge               | Provision and manage deliverability-focused mailboxes     |
| Mailforge and Infraforge | Manage mailbox infrastructure with domain and DNS context |
| Warmforge                | Track warmup and placement metrics for mailbox health     |

## Operational checklist

1. Confirm mailbox is configured before enrollment and launch flows.
2. Assign the right mailbox to the right workspace and sender context.
3. Monitor warmup and placement performance continuously.
4. Reduce or rebalance sending when mailbox health drops.
