Hi @jasindsd 


How does telnyx work? Do you choose one number to send to every time or multiple numbers at a time. 

I dont see this working for several reasons. 

10,000 numbers means 10,000 tasks , is that a per day number? 

Yes i can send more than 10k sms from 1 numbers , no problem.

How i can set 📐

Hi @jasindsd 


Using Google Sheets won't be possible for this. I would suggest using Airtable instead. 


It would be very tricky to avoid throttling by Zapier (100+ tasks triggering at the same time). Keep in mind you need a paid plan that allows 500K Tasks per month (10K sms per day x 30 days = 300K) 


Are those daily or one time? The approach would be a bit different but same idea


What you would do is to first set Airtable. In Airtable you would need to create a view that would trigger less than 100 sms at a time. You can achieve that in many ways. Best way would be to add an autonumber field and create a formula that would trigger at certain times per day based on this autonumber. 


Upon sending the sms you need an Action to update Airtable to specify that the message was already sent (preferably a date field so you can filter it out of the view then by choosing a filter “Date Message Sent is not Today”). This would double the amount of tasks you need per month, i.e.: 600K tasks. In case they are one time tasks then you dont need this part AND the trigger would be New Records in Airtable View instead of New or Updated Records in Airtable view. 


You could then add the Action to send the sms in telnyx
