# Add people to a blast's audience

Appends the addresses a draft blast will reach: `recipients` as `[{address, displayName, sourceRowId}]`, at most 500 a call. Answers 200 with a result per address — `ok` and `changed` for each, and a sentence for any one refused — never a 4xx because a single address was wrong. An address whose shape does not fit the blast's kind (an email in a text blast) is refused there and then instead of failing quietly at send time. Append-only: nobody can be taken out, and nothing can be added once `post_blasts_id_schedule` has frozen the audience, so a mis-built list is fixed by cancelling the draft and building another.

Access class: `workspace`.
