Example
Inputs
Choose exactly one scope:{ all: true }, { contactEmail }, or paired { startDate, endDate } values in YYYY-MM-DD form. The second argument can select { account }.
Output
Returns nothing. This deletes bounce history; it does not guarantee future delivery. Use{ all: true } only when you intend an account-wide deletion.
