Does mail expire in borderlands 3

In Borderlands 3, mail does not expire. Once you receive a piece of mail, it will remain in your inventory until you choose to delete it or it is automatically removed due to storage space constraints.

However, it's worth noting that some types of mail may have specific requirements or deadlines to complete certain tasks or quests. For example, some mail may require you to complete a specific task within a certain time frame, and if you don't complete it before the deadline, the mail may become invalid or expire.

But in general, regular mail in Borderlands 3 does not have an expiration date and can be kept in your inventory indefinitely.
