FILLED EXAMPLE (fictional)
Fictional package uses two approved files of 2 and 1 MiB. Encoded model about 4.11 MiB plus 0.25 MiB allowance yields about 4.36 MiB. A fictional 5 MiB budget is independently checked against actual sender and recipient requirements. Final prepared-message size and content still require verification.

BEFORE USE
Replace every bracketed field. Examples are illustrative. Confirm your agreement, local invoice requirements, and applicable tax treatment separately. This download does not send an invoice or update a billing record.
