We sell B2B e-commerce infrastructure to mid-market retailers — the kind of companies running 5-50 store locations plus an online presence. Our buyer is usually the head of operations or the owner-operator.

These people don't check email all day. They live on their phones, mostly answering supplier calls and managing store ops.

## The SMS experiment

About six weeks into our engagement, SmarterOutbound suggested testing SMS to merchant phones. I was uncomfortable about it — felt invasive, felt like we'd get reported. Their compliance angle was that we'd source numbers via legitimate channels, identify ourselves clearly, and honor opt-outs immediately. We tested with a list of 200 contacts.

The results from the SMS test:

- 11% reply rate (industry average for cold SMS is under 3%).
- Most replies were polite "not interested" or "send me an email" — both of which gave us useful data.
- 6 booked discovery calls from the 200 sends.
- Zero complaints, zero spam reports.

## Why this matters

For comparison, the same 200 contacts had been emailed twice and LinkedIn-DMed once before the SMS went out. Email had produced 1.9% reply rate and LinkedIn 4.2%. SMS was almost three times the next-best channel.

We've now scaled SMS to about 600 messages per week. It's our highest-converting channel and the meetings from SMS are the highest-intent (the people who reply to SMS are the people who actually wanted to talk).

## Four stars because

The volume is lower than the other channels. SMS isn't a high-throughput play. If you're trying to fill an entire sales team's calendar from cold outbound, SMS alone will not do it.

Also: the compliance side was complicated. We had a 30-minute call with our lawyer about TCPA implications. SmarterOutbound's compliance docs were thorough but this isn't a "set it and forget it" channel — you need to actively manage it.

## Recommendation

If you sell to a buyer who lives on their phone — retailers, restaurant operators, healthcare providers, real estate, anyone who isn't deskbound — SMS deserves to be in your channel mix. Just do it through someone who handles the compliance side correctly.
