You can do this two ways: use the weekly sender for a quick setup, or use a Google Sheets formula so the spreadsheet itself drives the schedule.
Set 09:00 once
The send stays at 9:00 AM every Friday.
Pick Friday
Weekly mode keeps the schedule locked to Fridays.
Preview before send
Check the next dates before you confirm anything.
Quick setup
Open the Recurring SMS Sender.
Choose Weekly and select Friday.
Set the time to 09:00.
Pick an end date and send.
Before you start
Make sure the timezone in your account or browser matches the local Friday 9:00 AM you want. If your timezone is off, the message can fire at the wrong hour even though the weekday and time look correct.
Best simple rule
If you prefer working directly in Google Sheets, create one row for each Friday send and use the formula to register the SMS from the sheet itself.
Suggested sheet columns
A = Friday date, B = phone number, C = message, D = time, E = formula result.
This is the most spreadsheet-friendly option when your message list already lives in rows.
If you want a simpler one-time schedule instead, use SCHEDULESMS. If you want repeat sends without managing rows manually, use the recurring sender above.
Step 1
Create a row for each Friday send you want.
Step 2
Put your phone number, message, date, and time into columns.
Step 3
Use `=SCHEDULESMS(message, phone_number, date, time)` to register the send.
Step 4
Copy the row down for future Fridays so the sheet drives the schedule.
No. Once the recurring schedule is submitted, Sheet SMS handles the future sends in the cloud.
Yes. Open the recurring sender again, adjust the weekday or time, and submit the new schedule.
Use the main scheduling feature instead of the recurring sender.
Set an end date when you create it, then recreate or stop it if your plan changes.
