From the site of the CSCA — the group that grants and administers the shortcodes used in SMS messaging.
From their “Best Practices” page:
Get Permission
- It is vital to respect a wireless subscriber’s right to privacy. ALWAYS gain permission from the people you plan to engage by employing an opt-in procedure.
- Gaining permission saves money. Each message sent costs money. Ensuring the customer wants to receive messages avoids any waste of your marketing budget.
- Sending unsolicited messages creates a negative impression and erodes brand recognition; prompting subscribers to avoid the service and file complaints.
- Avoid purchasing lists of numbers; always have customers opt-in and subscribe to receive content. For applications that require payment, create double opt-in process for subscribers that ensure willing participation.
Sounds like pretty good advice. Makes you wonder if it might be kind of a dick move to SMS people without their explicit prior permission.
