SMA Communications is an information provider focused on connecting our clients to their audiences across multiple distribution channels via email, postal&phone There is no dedicated opt-out or deletion tool — this is a domain-sales site (the page appears on a parked/for-sale domain) whose policy only tells you to use the general 'contact us' form, phone (+1 303-893-0552), or email listed at the bottom of the privacy policy. Deletion is discretionary: the company explicitly reserves the right to keep your data for fraud, legal, contractual, or registry/ICANN reasons, and no response deadline is stated.
