SMS vs email for sales outreach — when to use each
Email scales and carries detail; SMS gets near-instant open rates but demands consent and brevity. Use email for cold reach and SMS for warm, opted-in follow-up. Here's the breakdown.
Short answer: email is the workhorse for cold outreach — it scales, carries detail and links, and (cold) needs no prior consent beyond compliance basics. SMS has near-instant open rates but demands prior consent (TCPA/10DLC), brevity, and respect for quiet hours — so it's best for warm, opted-in follow-up (reminders, replies, booked-call nudges), not cold prospecting. Use them together: email to reach, SMS to convert the warm ones.
- Use for: cold reach, detailed value, scale.
- Watch: deliverability, reply rate.
SMS
- Use for: warm follow-up, reminders, fast yes/no.
- Watch: consent (10DLC + opt-in), quiet hours, 160-char brevity, opt-out.
The combined play
Reach broadly on email; once someone opts in or engages, a timely SMS converts faster than another email. Autocloz runs both as steps in one sequence with the compliance gate on the SMS side (consent + quiet-hours + STOP).
