Bulk SMS campaigns — sending texts to a list safely
Send a text campaign through your own Twilio account: audience, consent, quiet hours, test sends, and delivery reports.
SMS campaigns send through your own Twilio account — connect it under Settings → Text messaging first. Campaigns reuse the same lists and segments as Email Marketing, but only contacts with a valid mobile number are texted.
Before a campaign can leave draft you must confirm your recipients opted in to receive texts. Anyone who replies STOP is added to your opt-out list automatically and will never be texted again by campaigns, chat, or workflows. The first message to a new number automatically ends with “Reply STOP to opt out.”
Sends are paced to your configured messages-per-second and only go out between your campaign’s quiet hours (9 am–8 pm by default, in the campaign’s timezone). Use the preview to see recipient counts, estimated message segments, and plan usage before you schedule — and send yourself a test first.
