How old should my domain be for cold email?

Ideally, your domain should be at least 3-6 months old before sending cold emails at scale. Domains under 30 days are high-risk and likely to trigger spam filters. If your domain is new, start with a proper warmup period.

Can I use a brand new domain for cold email?

Yes, but with extreme caution. New domains require 4-6 weeks of warmup before scaling. Start with 10-20 emails per day, gradually increasing volume while monitoring deliverability and bounce rates.

Should I use a separate domain for cold email?

Yes, using a secondary domain protects your main domain's reputation. If your cold email domain gets flagged, your primary business domain stays unaffected. Use a variation like outreach.yourdomain.com or yourdomain.co.
