Mailbox pricing. For your app.

Yes. Email plans include mailboxes. A Mailbox plan raises those limits; when you have both, the higher limit applies rather than the two adding up.

Start with the number of mailboxes, inbound and outbound messages, attachment volume and retention period.

Review the applicable plan or written proposal for its amount, currency, included capacity, renewal terms and additional-use rates.

Mailbox count, message volume, storage, retention and attachment requirements affect scope. Include domains, access requirements and support when describing the workload.

Your quote should distinguish included capacity from additional usage, implementation and support. Confirm the currency, billing period and cost of additions before starting.
