SMS is sent through Twilio with full A2P 10DLC compliance baked in.
Setup
Settings > Integrations > Twilio. Connect your Twilio account or sign up. You'll need a registered A2P 10DLC campaign for US sending (Tormano walks you through it), or an alphanumeric sender for international.
Building a campaign
/sms-campaigns > + New Campaign. Pick template or write fresh, choose audience (saved view, tag, or list), preview cost (Twilio charges per segment, ~$0.0079 in US), and send.
Templates
Reusable like email templates. Same merge field syntax: Hi {{contact_first_name}}, your gift makes a difference!. Watch the character count — SMS messages over 160 chars split into multiple segments and cost more.
Opt-out handling
Every SMS auto-includes "Reply STOP to opt out". When a recipient replies STOP, Tormano logs the opt-out and excludes them from all future SMS — no more sends ever, no exceptions. Required by TCPA.
Click tracking
Same redirect-URL pattern as email. Track which links get clicked.
Cost
Twilio charges per segment. $10 typically buys ~1,250 messages. Tormano shows estimated cost before you confirm send.
