Whenever you get an error like below, it can mean a few different things.
1. DND is Enabled
When DND is enabled for a contact on the SMS channel or overall, our CRM doesn't send the SMS and will display 'Unsuccessful' in the conversation screen.
DND can be enabled from multiple reasons. Sometimes they will reply with 'STOP' or Unsubscribe via email and in order to comply with privacy legislation, we will stop the automations to prevent you from being flagged as spam.
2. Number is a landline number (Number validation)
When number validation is enabled, Elite Realty CRM checks if the contact's phone number is SMS-capable before attempting to send the SMS. If the number is not SMS-capable, Elite Realty CRM skips sending the SMS and shows an error in the conversations screen.
3. Sub-Account is new and undergoing ramped sending
For newly created sub-accounts, HighLevel gradually increases the sending limits to prevent spamming or phishing. You can choose to remove these restrictions if desired though it is not reccomended.
4.SMS sending privileges have been suspended due to a high error rate, opt-out rate, or carrier complaint rate
Elite Realty CRM monitors error rates, opt-out rates, and carrier complaint rates for all sub-accounts to prevent spamming and phishing. If any of these thresholds are exceeded, SMS sending privileges for the sub-account are suspended for a certain period. Any attempted SMS sending during this time will be skipped, and an error message will be displayed on the conversation screen.
