About This Site
How Many Cold Emails Per Day is a free resource built to give cold emailers a straight, data-backed answer to the most common question in outbound sales: "How many cold emails should I send per day?"
The answer — 50–100 per mailbox per day, across 3–5 domains — comes from real-world data across millions of cold emails. But the nuances matter: warm-up schedules, domain reputation, provider-specific limits, and infrastructure setup all affect your optimal sending volume.
This site is maintained by the team at Sales.co, an AI-first cold email platform that has helped 271+ sales teams send over 2 million cold emails. We built this resource because we've seen too many teams burn domains and tank deliverability by sending too much, too fast.
Why Trust This Data?
The benchmarks and recommendations on this site come from aggregate, anonymized data across the Sales.co platform. We track deliverability metrics across thousands of domains and millions of sends to identify the sending volumes that maximize reply rates without triggering spam filters.
