Alert Emails stopped sending and no response from Smartsheet Support for 3 days!


We rely on Smartsheet form for order processing and past few days the automated alert emails have stopped sending to all users except mine. Have logged a ticket with Smartsheet and 3 days later still no response. My MD is instructing me to move to another platform and cancel our subscription but I like Smartsheet, however if the support is not there then I may not have any other option but to move away....
