The channel sequence
- Email — pattern interrupt with specific research
- LinkedIn — social proof + a lighter ask
- SMS — only after opt-in or reply
- Voice — reserved for warm signals or opt-in inbound
What the agent coordinates
Suppression, timing gaps, message continuity, and reply routing so the buyer never gets the same pitch twice.
What to skip
Cold SMS to purchased lists. Illegal in most geographies, brand-damaging everywhere else.
