Every mailbox you create on your sending domains takes up one mailbox slot, for as long as it exists. To buy slots, open Email Infrastructure and click the plus on the Mailbox slots card. First pick the type: dedicated IP, shared IP, or Google and Microsoft. Each type has its own price per slot. Then choose a billing period: every three months, or yearly, which gets you two months free. The big number is what you'll pay each month, and the breakdown underneath shows the price per slot and the total. Set how many slots you need.
