InfraBenchmark

An index where 100 equals the average reply rate across all providers. A score above 100 means the provider is outperforming the average. Calculated as: provider's raw reply rate / average reply rate across all providers x 100.

Two independent agency owners who aggregate campaign data weekly. Combined, they manage 30+ clients and send approximately 1,000,000 emails per month. They remain anonymous to protect client relationships.

Every Sunday, campaign data is aggregated, normalized, and published. Data is lagged by 7 days to ensure complete reply attribution.

Reply rates are heavily dependent on campaign type, offer, and targeting. Showing raw rates would misrepresent infrastructure performance. The normalized index isolates the infrastructure variable.

We do not disclose specific infrastructure providers as it would compromise the neutrality of this benchmark. If demand is high enough, we may share this in the future.

If Provider A is the leader and the metric says "send 38 more per 1,000" for Provider B, it means you need to send 1,038 emails on Provider B to get the same number of replies as 1,000 emails on Provider A.
