6 min readUpdated June 2026

Before you begin

  • Phone & SMS connected with outbound SMS number
  • Recipients must have valid mobile numbers and marketing consent where required
  • Campaigns hub also lists SMS under /dashboard/campaigns

Create a broadcast

  • Bulk SMS (/dashboard/sms) or Campaigns → SMS
  • New campaign → pick from number, message body, recipients
  • Schedule now or later; max 500 recipients per send in UI

vs Messages inbox

  • Bulk SMS — one-way broadcast to a segment
  • Inbox Messages — two-way threads with replies
  • Cadences — per-lead automated sequences

Common issues

  • Send blocked — carrier or consent rules; see SMS opt-out article
  • Failed recipients — verify phone on each lead
