Is .info or .com Better for Cold Email Domains?

Short answer

Prefer .com. Use .info when budget matters more than speed, and give it more time.

Why the extension matters at all

Filters judge a domain by its own history first. Spamhaus describes its Domain Blocklist as "a list of domain names with poor reputation," calculated "from a wide range of observed domain behaviors." The extension is not a verdict by itself, but in practice cheap extensions warm up slower and react more to risky content than .com. We have not seen the extension decide placement on its own.

Where it matters most

Outlook with financial content. In our tests, the extension made a large difference only together with risky copy. With finance and lending offers, .info reached the Outlook inbox far less often than .co. With neutral copy, both did the same. If your audience is on Outlook and your offer is financial, the extension is worth the extra money.

Google. Google's sender guidelines don't mention domain extensions; they cover authentication, the reputation of the sending IPs and domain, and spam complaints. See Gmail sending cold email to spam.

If you choose .info

1. Warm it up longer. Plan at least 14 days plus a couple of extra weeks before cold email. See how long to warm up.

2. Start with neutral copy. Test your offer against a neutral email before you scale, especially for Outlook-heavy lists.

3. Split by provider. Measure Outlook and Google recipients separately so you can see whether the extension is costing you.

4. Check the renewal price. Some registrars sell cheap extensions at a promotional first-year price and charge much more on renewal. Know the second-year cost before you buy many.

Other extensions

The same logic applies to other cheap extensions: lower price, slower start. Whatever you pick, check new domains against public blocklists and Google Safe Browsing before use; Google's sender guidelines recommend checking "that your domain isn't listed as unsafe with Google Safe Browsing."

What we recommend

.com for cold email domains, up to 5 mailboxes per domain and warm-up on every mailbox. Use .info when cost matters, with a couple of extra weeks of warm-up. Domains you buy in the app are registered for one year in your name. See pricing.
