This could be due to one of a few reasons. To determine why your SMS reminders didn't send, go through this quick checklist:
1. Check SMS Reminders are Enabled for clients
If you've recently turned off your SMS Reminders, you may have also disabled your client's from receiving reminders. Click here for more information on enabling your client for reminders.
NOTE: SMS Reminder Campaigns are sent at the same time each day, generally around 12-1pm. As such, if you enable your reminders too late in the day—you will miss the cut off. Your reminders will send normally from the next day onwards.
2. Check the "Error" message in Campaign Report
Go to Marketing > Campaign Report > change dates to the day when the reminders didn't send > click Recipients for the SMS Reminder Campaign.
If your SMSs attempted to send but were unsuccessful, it will say Error in the Status column. Click the "Error" link and read the error message.
It might tell you that the client had no mobile, or that you have no credits left. If the message is easy for you to understand, you'll need to go ahead and fix the issue i.e. enter a mobile number into the client's details or buy credits etc.
If the error message reads: "SMS PROVIDER ERROR: ERROR: error parsing response"—
This means there was a possible momentary server/internet connection issue at the time of sending, so all you need to is click the Back To Main Report link and click Re-Send to re-send the SMS reminder campaign then and there.
3. Check that you have your Appointment Reminders enabled
Go to Admin > SMS & Email > you should have ticks next to either (or both if it's your preference) 1st Appointment Reminder and/or 2nd Appointment Reminder.
4. Check that you are connected to Simple Salon Messaging
Go to Admin > SMS & Email > in the SMS Account Setup section, check that you are connected and that your credit balance is displaying.
5. Check that you have enough credits
Go to Admin > SMS & Email > in the SMS Account Setup section, check that you have enough SMS credits. If you don't, you'll need to click Buy Credits and follow the prompts to purchase some more.
6. Check that you haven't put a number in the 'Dedicated Number' Section
If you've recently put in a number or word in the Dedicated Number section in SMS Account setup, (Admin > SMS & Email) you'll want to remove it as this turns off 2-Way Communication. Client's will be receiving the message, however you will not be able to receive the response. To purchase a unique number correctly, please click here for more information.
