I recommend that you create one email account per domain.
Other people in the cold email community say you can create more than one email account per domain.
However, in this article, I will explain why I think you should only create one email address per domain, and what could happen if you try to create more.
The reason why you should only create one email account per domain is because it is safer.
The more email accounts that you create on a single domain, the more overall email volume you will be sending on that domain, and the more likely you are to be blacklisted by email service providers such as Gmail and Outlook.
In my opinion, it’s best to view your email accounts as long term assets.
You can play it safe and have an email account that always delivers to the primary inbox, year after year. Or, you can get greedy, and add multiple email accounts to each domain, eventually leading to your domains being blacklisted and your emails being sent to spam.
On a related note, I recommend that you send 40 cold emails max per day per email address; this ensures that you stay in the safe zone, and don’t get blacklisted. You can learn more about this in my article How Many Cold Emails Can You Send Per Day Before Going To Spam?
You can then scale your cold email outreach by buying additional secondary domains.
If you create multiple email accounts on a single domain, then your domain is more likely to be blacklisted, and your emails will go to spam.
This is due to the fact that you would be sending a higher overall volume of emails if you have multiple email accounts on a single domain.
If you don’t know what multiple email accounts on a single domain looks like, then check out the below example:
It’s safer to create just one email account per domain, and then scale by buying additional secondary domains.

Most people don’t want to spend a lot of money on their cold email campaigns.
They opt for the cheap route, which is why they create multiple email accounts on each domain. This allows them to buy less domains, since each domain costs money to register each year.
This might work for a short period of time, but eventually, their domains get “burned” (blacklisted) by email service providers, and they are back at step one.
It’s the same reason that some people don’t want to set up their email accounts via Google Workspace, because all they care about is price.
Google Workspace is slightly more expensive than other options, but Google has the best (most trusted) email servers, meaning that your deliverability will be better if you send cold emails from email accounts that were created via Google Workspace.
There is no correct answer to this question. It depends on what your goals are.
If you are doing a highly targetted cold email outreach campaign, to a small number of companies, then you are probably fine using just one domain.
The below tweet from Brex's Ex-Chief Revenue Officer describes their most successful outbound sales campaign ever. In this example, they only reached out to 300 companies, and they were able to close 169 of them as paying customers. In this scenario, they would only need to use one domain for their cold email outreach.

Brex launched in 2018 as the first corporate card for startups. After launch, when we were still ~30 employees and near 0 rev, we ran the most successful outbound campaign I've ever seen.
There are people who think that volume is what matters. If you want to send a high volume of cold emails, then you will need to buy multiple secondary domains to create additional sender email accounts.
The reason why you need to do this if you want to scale is because each email account can only send about 40 cold emails per day (before risking poor deliverability). So if you wanted to send 400 emails per day, then you should buy 10 domains.

A final thing that I will mention is that if you are selling something that no one wants, then it doesn't matter how many emails you send, you won't make any sales. The below tweet highlights this reality well:

You can email the entire planet and you're still not going to get calls if you're selling something NOBODY WANTS TO BUY
You should create only one email account per domain. If you create multiple email accounts on a single domain, then your domain could be blacklisted.
Yes, it is more risky to have multiple email accounts set up on a single domain. The higher your email sending volume is, the more likely you are to be blacklisted. If you have multiple email accounts on a single domain, then your overall volume will be higher.
I recommend that you only create one email account per domain.
Some people say that you can create more, but this is risky, and will most likely result in your domains being “burned” (blacklisted) by email service providers.
On a related note, you should not send cold emails from your company’s primary domain. You can learn more about this in my article Should You Send Cold Emails From Your Primary Domain?
