About Setting up a New Domain
Last updated: June 12, 2026
Most companies create separate domains for sales activities to ensure that their emails reach the right inboxes for their prospects. The primary benefit of using dedicated domains for sales is to safeguard the deliverability and overall reputation of your main company domain. Additionally, by adding new domains, you can create extra mailboxes, increasing your daily email output.
While alternative domains are great for scaling, launching high-volume outbound campaigns on a new domain too quickly is the primary cause of immediate deliverability failure.
Our recommendation is for new customers to start sending email volume from their main domain. This provides an immediate, healthy sender reputation. You can absolutely set up and warm up alternative domains in parallel.
Ideally, you should segment domain email activity based on specific functions. Here are a few examples:
You should use a specific domain for marketing purposes.
Marketing emails can negatively affect domain reputation and they will impair the deliverability of all users on that domain.
We recommend that your sales team uses a minimum of 2 domains.
Having multiple domains will allow you to avoid spikes in email activity, which will contribute to better deliverability and higher open rates. Multiple domains also act as “deliverability insurance.” If the sales team has a deliverability problem with one domain, they can pause activity on that domain and switch it to a different one without ever facing quota attainment problems.
This approach helps prevent an unhealthy outreach domain from negatively impacting your sales team’s ability to successfully engage with opportunities.
Consider what that domain should be
Be a .com email - There's more recognition and trust around a .com. Many tech companies utilize others (e.g. .io) with no problems. But if you are in doubt, we recommend .com.
Be short and simple, append/prepend words like “get”, “app” to your main domain
(e.g. getamplemarket.com vs. amplemarketoutboundsalestool.com)
Be an alias domain (or parked domain):
This is just a complex way of saying it's a new URL that redirects to your primary website
It's important to note that this alias should not be attached to your existing G-Suite for your primary domain, as this would cause the same effects as a subdomain (due to shared IP)
Not be a subdomain of your current domain (e.g. blog.amplemarket.com)
This is too attached to your current domain and thus directly affects your primary domain’s health
Be similar to your current domain (e.g. ample-market.com vs. amplemarket.com)
This is for branding so your emails do not seem to come from a third party.
Verify a domain is available and not owned by someone else
We love using domains.squarespace.com. If available, you can even purchase your shiny new domain right through Google which makes setting up G-Suite easier!
If you use Microsoft and not Google, we recommend using GoDaddy Domain Search which will also facilitate setting up Microsoft 365.
Almost every domain hosting website will give you instructions on how to redirect your domain if it was purchased from that particular website. You can find more information on redirecting GoDaddy domains here and Google domains here.

Final warnings and advice (for Outlook email addresses)
Please note that during the trial period of your new Microsoft 365 mailboxes, the IP reputation might be kept low which can lead to emails bouncing.
You can contact Outlook support to request an exception for the low-reputation IP address until you’re able to purchase licenses.
