Send SMS from Sheets — Telesign

Send bulk personalized SMS via your own Telesign account from a sheet

smstelesignbulk textmail mergemessagingpersonalized
Send personalized bulk SMS straight from Google Sheets through YOUR OWN Telesign
account. Map a phone-number column and write a message template with {{merge
fields}}; one click sends the whole list and writes each Telesign reference id
(or the error) beside the row.

WHAT IT DOES
• Bulk SMS from a sheet — one SMS per non-empty phone row, sent in a single click.
• Merge fields — {{Header}} placeholders pull values from other columns by header
  name (or A1 column letter), so every message is personalized.
• Header-row toggle — treat the first row as headers (on by default) to reference
  columns by name.
• Status column — the Telesign reference_id on success, or "error: …" on failure,
  is written beside each row.
• Resilient batch — a row that fails is marked and the batch keeps going; it never
  aborts on one bad number.

GREAT FOR
• Verification codes, alerts, and account notifications.
• Reminders and announcements to a contact list.
• Anyone who keeps their recipients in a spreadsheet.

REQUIRES YOUR OWN TELESIGN ACCOUNT
This is a connector: you bring your own Telesign Customer ID and API key. We do
not resell, proxy, or hold a master account — messages are sent directly from
your authorized session, and Telesign bills your account directly at your own
rates. Credentials are stored privately in your Google account.

FREE & PRO
• Free: 25 SMS/month.
• Pro: unlimited sending. 14-day full trial.

Privacy-first: works only on your ACTIVE spreadsheet (current-file-only scope) —
never all of your files. Minimal, non-restricted scopes. Responsive support and
regular updates.
