FAQ
Is 50 cold emails per day too much?
For a warmed domain with clean lists, 50/day is often fine. For a new domain, start at 10-20. Scale up slowly and watch deliverability.
What happens if I send too many?
Your domain can get throttled or blocked. Emails may land in spam. It takes time to recover. Better to send fewer with higher quality.
Should I use multiple domains?
Some do for scale, but it adds complexity. Warm each domain separately. See how to warm up cold email domain for the process.
