While I appreciate removal of Mrs. R's name from your mailing list, additional thought leads to realization of deception in your organization’s fundraising.
Your literature states Mrs. R was “nominated” to the George Bush Leadership Honor Roll. However, your email reply states her name “was purchased on a list from other similar organizations.”
How does “purchased” equate with “nominated”? While your organization’s action might be in keeping with fundraising activities, the action is deceptive.
