Why Your Cold Email Domain Matters
The domain you use for cold outreach directly impacts deliverability, trust, and response rates. A professional sending domain is essential for successful cold email campaigns.
Protect Your Main Domain
Never send cold emails from your primary business domain. If your sending domain gets flagged or blacklisted, your main domain stays protected.
Improve Deliverability
A properly warmed sending domain with correct DNS settings (SPF, DKIM, DMARC) dramatically increases your chances of landing in the inbox.
Build Trust & Credibility
A professional-sounding domain instantly builds credibility. Prospects are more likely to respond to emails from trustworthy-looking domains.
Cold Email Domain Best Practices
Domain Selection Tips
- Use variations of your main domain (e.g., getacme.com if your main is acme.com)
- Keep it short, memorable, and professional
- Avoid numbers, hyphens, and unusual TLDs
- Match your company name or service offering
Setup Requirements
- Configure SPF, DKIM, and DMARC records
- Warm up new domains for 2-4 weeks before heavy sending
- Create a simple landing page on the domain
- Set up professional email signatures
Volume Guidelines
- Start with 10-20 emails/day per domain during warmup
- Max 50-100 emails/day per domain for cold outreach
- Use multiple domains to scale volume safely
- Monitor bounce rates and spam complaints
TLD Recommendations
- .com - Most trusted, highest deliverability
- .io / .co - Good for tech/startup outreach
- .net - Solid alternative to .com

Frequently Asked Questions
How many cold email domains do I need?
Plan for 1 domain per 50-100 emails/day you want to send. If you need to send 500 emails daily, you should have 5-10 warmed domains rotating. This protects deliverability and spreads risk.
Should the domain match my company name?
Ideally yes, but variations work too. If your company is "Acme Inc", domains like getacme.com, tryacme.io, or acmehq.com are all good options. The key is that it looks professional and related to your business.
How long does domain warmup take?
Proper warmup takes 2-4 weeks. Start by sending 5-10 emails/day to engaged contacts who will open and reply. Gradually increase volume by 5-10 emails every few days. Use a warmup service to accelerate this process.
What if my domain gets blacklisted?
This is why you use separate domains for cold email. If a domain gets blacklisted, stop using it immediately, request removal from blacklists, and switch to another warmed domain. Your main business domain stays safe.
Do I need a website on my cold email domain?
Yes, at minimum. A simple landing page with your company info, logo, and contact details makes your domain look legitimate. Email providers check if domains have websites when evaluating sender reputation.
