   • To prevent malicious users from attacking subscription endpoints, SMN limits the number of confirmation messages that can be sent to an endpoint within a specified period. For details, see Traffic Control over Subscription Confirmation.
   • SMN does not check whether subscription endpoints exist when you add subscriptions. However, subscribers will not receive notification messages until they confirm their subscriptions.
   • After you add a subscription, SMN sends a confirmation message to your subscription endpoint. You can confirm the subscription within 48 hours through the confirmation link via your mobile phone, mailbox, or other endpoints.
   • Subscription confirmation messages will be counted as messages sent and will be billed.
