See what's working in cold email right now

It's a score where 100 is average. If a provider scores 110, it's performing 10% better than the average across all providers. If it scores 90, it's 10% worse. We calculate it by dividing each provider's reply rate by the overall average, then multiplying by 100.

We're two cold email agency owners. We've been in the space for about a year and a half, do a collective $150k+ in MRR, manage 30+ clients, and send roughly a million emails per month. We built this because we wanted to know which infrastructure actually works best, and figured everyone else does too.

Every Sunday we sit down, pull the numbers from our campaigns, normalize everything, and publish it. The data is lagged by 7 days so all replies have time to come in before we count them.

Because reply rates depend heavily on the offer, the list, and the copy, not just the infrastructure. If we showed raw rates, people would draw the wrong conclusions. The normalized score strips out everything except the infrastructure difference, which is what actually matters here.

Email testing@infrabenchmark.com. We read every request and prioritize based on what the community wants to see.

It's simple: if Google is the leader and Azure shows +125, that means for every reply you get on Google, you'd need to send 125 more emails on Azure to get that same reply. The lower the number, the closer the performance.

We run 30+ campaigns across our agencies. For this benchmark, we picked the ones from our longest-running, highest-volume clients, accounts that have been active for 6+ months. That way the data is meaningful, not based on one-off tests.
