Reply Rate

Reply rate is the percentage of outbound messages — emails, LinkedIn messages, or other touchpoints — that generate a response from the prospect. It is calculated by dividing the number of replies by the number of messages delivered, then multiplying by 100.

Reply rate is one of the most actionable metrics in outbound sales because it sits at the intersection of targeting and messaging. A low reply rate means either you are reaching the wrong people, saying the wrong things, or both. Unlike open rates (which are increasingly unreliable due to email privacy features), replies represent genuine engagement.

Benchmarks vary by channel and audience, but for cold email outreach in B2B, a 5-10% reply rate is typical for a well-targeted campaign. Top performers consistently hit 15-20%. LinkedIn InMail tends to run higher, often 10-25%, though volume capacity is more limited.

To improve reply rates, start with targeting. No message — no matter how well written — will get replies if it is sent to people who do not have the problem you solve. Once targeting is solid, test messaging variables: subject lines, opening lines, the specificity of your value proposition, and the call to action. Shorter emails almost always outperform longer ones in cold outreach.

Track reply rates by sequence, by step within the sequence, and by persona. You will often find that your third email in a sequence outperforms the first, or that directors reply at twice the rate of VPs. These patterns inform how you structure your SDR operations and where to focus optimization efforts.
