Hi there @jasindsd - let me try to help you out here. I am Rachael, on the Community team- and I’m going to break down your question a little bit!

You want to have timed SMS messages sent to contacts you are updating in batches each day. Currently you are using Twilio to send these out. 

One suggestion I would have in running your Zap is exploring the Delay step, this allows you only to run the Zap at certain times, and pause so you aren’t sending all 20k messages at once. 

But to back up a bit, for building we talk about two parts of your Zap; A trigger and an action , you have your action chosen (sending a text) but your trigger could be any number of things. It could be using Twilio as well (like “every time a new phone number is added”) but it also could be something like Google Sheets. Where are you collecting these number and names? My suggestion would be to add them to a google sheet and have the Zap run off that, but if you send us some printscreens we can troubleshoot with you more.

Welcome again to the Community and we hope we can get you to the right spot!

Hi again @jasindsd - I saw you posted similar questions twice, I went ahead and removed the other one and am merging replies here :] 


In short, you can do this with Twilio, and I saw you also contacted our friends in support, which is great! I am pasting their advice below too: 

You can space out the time these SMSs are sent in many different ways. Either with Delay steps, or by using Schedule by Zapier as your trigger.


Let us know how you get along in your progress and we look forward to following along!
