Buying the right domains is the first step in building a cold email infrastructure. Here is exactly how to do it in 2026. Step 1: Choose domain names Your cold email domains should be variations of your primary brand name. If your company is Acme Software at acmesoftware.com, good secondary domains include: getacmesoftware.com, acmesoftware.co, tryacmesoftware.com, acmesw.com, hiacmesoftware.com. The domain should look legitimate if a prospect glances at it. Avoid random words, numbers, or hyphens that look suspicious. Step 2: Choose the TLD .COM is the gold standard. It carries the most trust with both email filters and human recipients. If .COM is not available, .co, .io, and .dev are acceptable alternatives for tech companies. Avoid unusual TLDs like .xyz, .info, or .biz — they are heavily associated with spam. Step 3: Choose a registrar Namecheap, Cloudflare, and GoDaddy are the most popular domain registrars for cold email. Cloudflare offers at-cost domain pricing. Namecheap is straightforward and affordable. GoDaddy has the widest selection but tends to be pricier. Step 4: Purchase the domains Buy two to five domains to start. At $10 to $15 per domain per year on .COM, this is a minimal investment. Register them for at least one year — very short registration periods are a negative signal. Step 5: Set up a landing page Every cold email domain should have a live website. Even a simple one-page site with your company name, a brief description, and contact information is sufficient. This establishes legitimacy for both email filters and any prospect who checks your domain. Step 6: Configure email hosting Set up Google Workspace or Microsoft 365 on each domain. Create two to three email accounts per domain using real-sounding names. Step 7: Configure authentication Set up SPF, DKIM, and DMARC DNS records for every domain. Verify with the SPF Checker and DMARC Checker. Step 8: Warm up Start warmup on every account. Wait at least 14 days before sending any cold emails.
