Domain registration was one of the most common reasons people never got cold email off the ground. Before ListKit Bundles, it was one of the first walls you hit: figure out how many domains you need, go to a registrar, buy them all upfront, configure DNS records, connect them to your sending tool, and hope nothing broke along the way.
​

For most business owners, that process was either too technical, too expensive, or both. An upfront domain cost of $300 to $3,000 per year, depending on your sending volume, before you have sent a single email, is a real barrier. A lot of people paid it, got something wrong in the setup, and ended up in spam anyway.
​

ListKit removes that wall entirely. Domains are included. You pick the names you want, ListKit handles everything else, and you move on.
​

To send cold email safely at volume, you need sending domains that are separate from your main business domain. This protects your primary domain and company email reputation from being flagged by inbox providers.
​

Here is what those domains cost if you source them anywhere else:
​

These are typical annual registration costs (about $15 per .com domain), paid upfront before a single email goes out. With ListKit Bundles, every one of these is covered for as long as you are subscribed.
​

The domain cost was never just about money. It was about the entire process that came with it, the research, the registrar accounts, the DNS setup, the troubleshooting. Every step was a decision point where something could go wrong, and most people did not have the cold email expertise to know if they got it right.

By including domains in the subscription, ListKit eliminates that entire layer. There is no separate purchase, no technical configuration to figure out. You focus on who you want to reach and what you want to say, ListKit handles the infrastructure.
​

This is the same philosophy behind everything in Bundles. The cold email industry has historically made things as complex as possible because complexity creates dependency on more tools. ListKit is built to do the opposite, collapse the entire stack into one subscription, remove every unnecessary decision point, and make cold email accessible to any business owner regardless of their technical background.
​

When domains are described as free, that covers more than just the registration fee. Everything below is handled for you at no additional charge:

The only decision you make is what you want your domain names to be.
​

Some platforms have offered free domains as a promotional bonus, capped at one or ten domains, for a limited time. ListKit includes 20 domains for every 1,000 emails per day (200 domains at 10,000 per day), covered for as long as you are subscribed.
​

This is not a promotion. It is part of how Bundles is structured, one subscription, everything included. The domain registration cost is built into the model because removing it is part of what makes cold email actually accessible. So as long as you're subscribed to ListKit, you won't need to worry about the domains' cost.
​

From the moment your domains are registered, you are saving money you would have otherwise paid upfront, and more importantly, you are skipping an entire layer of setup that has stopped a lot of people from ever getting started. Your domains are configured correctly from day one, and you never have to think about them again.
​

Can I choose my own domain names?
Yes. If you choose Generate new domains during setup, enter your main domain and ListKit generates .com variations to pick from. These need 14 days of warmup, plus up to 72 hours to register domains and start warmup (about 2 to 3 weeks from signup). If you choose pre-warmed domains (recommended), ListKit assigns already-warmed domains and you can send within minutes.
​

What happens to my domains if I cancel?
Domains and inboxes are part of your ListKit service. Cancelling does not give you an automatic right to keep or transfer them, and any transfer is at ListKit's discretion. See What is ListKit's refund and cancellation policy?
​

Do I pay anything annually for my domains?
No. Domain costs are fully covered by ListKit for as long as you are subscribed. There are no renewal fees passed to you. See How does ListKit billing work?
​

Can I use domains I already own?

​

Why do I need separate domains at all?
Sending cold email at volume from your main business domain puts it at risk of being flagged by inbox providers. Separate sending domains protect your primary domain and company email reputation.
