Opt-out rate is the share of recipients who reply STOP or otherwise unsubscribe after a send. It's one of the most useful numbers in texting, not because you want it at zero, but because it's your earliest warning that something's off. Watching opt-out rate per send tells you when you're over-texting, off-target, or texting people who never really opted in. Here's how to read it.
What does opt-out rate measure?
It measures how many people leave your list in response to a message, as a percentage of those who received it. Some opt-outs are normal and healthy, people's interests change, and a clean opt-out is far better than a complaint. What matters is the pattern: a low, steady opt-out rate is the cost of doing business, while a spike signals a problem with that specific send or the list it went to. Track it per send, not just in aggregate, so a single bad blast doesn't hide in the average.
What's a normal opt-out rate?
There's no universal number, and it varies by list, message, and audience, but the useful frame is relative, not absolute. Know your own baseline, and treat deviations from it as the signal. A send that opts out people at your normal rate is fine; one that spikes well above it is telling you something. Chasing a specific "good" percentage matters less than watching for changes against your own history.
What does a spike mean, and why does it matter?
A spike usually means one of a few things: you texted too often, the message was irrelevant or off-tone, or you texted people who never genuinely opted in. Diagnose which before the next send rather than pushing through. It matters beyond list size because a high opt-out or complaint rate is a deliverability signal to the carriers, sustained high opt-outs tell them your traffic is unwanted, and they respond by filtering. So opt-out rate is both a list-health gauge and a protector of your ability to deliver at all. See the benchmarks.

Why does opt-out rate matter for deliverability?
Because a high opt-out or complaint rate tells the carriers your traffic is unwanted, and they respond by filtering. So opt-out rate protects your ability to deliver, not just your list size.
