Operated by WSOR, LLC · omessage
omessage (omessage.osterman.co) sends
account-notification text messages — one-time verification codes and
new-activity alerts — only to its own registered users who ask for them. Providing a phone
number is optional and is never required to use omessage. There is no marketing list, and no third
party can opt a user in.
How a user opts in
- Sign in to your omessage account at omessage.osterman.co.
- Open Settings → Notifications → Phones.
- Enter your own mobile number and tick the consent checkbox (unchecked by default).
- Submit, then enter the one-time code omessage texts to that number to confirm it.
Only after verification do you receive notifications, governed by the settings you control.
The consent form a user sees
