What the Google Sheets SMS add-on is for

An SMS add-on connects spreadsheet rows to text messaging. Sheet SMS supports immediate messages, scheduled SMS, recurring workflows, bulk sending, custom sender IDs where supported, and inbound reply workflows.

Permissions and account safety

Review the permissions shown by Google before installation. Use the add-on only in spreadsheets containing contacts you are authorized to message, and keep consent and opt-out records with the campaign data.

After installation

If the Sheet SMS menu does not appear, refresh the spreadsheet and reopen Extensions. If a formula returns an error, check the setup and troubleshooting guides before re-entering the formula multiple times.
