0 Scheduled Emails and SMS Stuck on Pending 1 Jad Taylor posted 9 Years Ago Scheduled Emails and SMS do not send and stay stuck at Pending after the scheduled delivery date and time. Emails and SMS sent without delay go through without trouble. We use Mandrill to send emails and Twilio for SMS. Neither Mandrill nor Twilio see the pending outbound email or SMS, leading me to believe the hang up is within Rock. The only adjustment I have made is to adjust the cron and Delay due to similar issues outlined in this question https://www.rockrms.com/Rock/Ask/Troubleshooting/Questions/561.
