Professional Email Addresses
Why funding institutions require an owned domain, and the short version of how to have one.
On a funded transaction, the principal, the principal’s attorneys and accountants, and the EPC contractor engaged under the funding package correspond from addresses on domains they own. That is a condition. For every other party — intermediaries, subcontractors, suppliers and consultants — it is not a condition, but it is how the party’s professionalism is first read. This page explains why, and how to have one.
If you already correspond from your own domain, this page does not apply to you.
Why ownership is the requirement
It comes down to ownership. A credible applicant can prove it owns the domain its address runs on.
Funding banks require email domains owned by the applicant. Google owns gmail.com. Microsoft owns outlook.com. A party writing from one of those addresses owns nothing in it — only permission, granted at will and revocable at will. Anyone can open one in any name, in a minute, verified by no one, and abandon it the same day.
Consider someone could register the email address donaldduck@aol.com and say that they are Donald Duck. Does that make the party authentically Donald Duck? No, but they can say they're Donald Duck. Right?
On the other hand, Magister Operis can prove on what date, at what exact time, and with what exact credit card Magister Operis has registered over 100 domains since 1997. That's the definition of accountability to a compliance officer and the funding banks.
Owning a domain produces the accountability banks require. The registrar records the exact date, time and payment instrument. Every renewal extends it. That record is held by a third party, it is checkable, and it cannot be created retroactively.
- If you already own a domain, there is nothing to do here. Use an address on it for the transaction and its documents. If you do not, the whole requirement is three steps: register a domain, add mail to it, and put that address on the paperwork.
- A paid business plan on any provider, carrying your own domain, satisfies the requirement in full. Encrypted providers — Proton, Tuta, Hushmail and others — run your own domain on their encrypted servers. The mail is encrypted; the domain stays yours. Encryption is encouraged, and is a separate matter from ownership.
- A website is not required, though it adds credibility to an applicant. What is required is owning the domain name of the email address being used within professional transactions. A site on the same domain provides professional consistency across an organization. A small correct site — who the entity is, what it does, who runs it, how it is reached — is a few hours of work with tools now commonly available. It does not need to be elaborate. It needs to be accurate and to agree with the documents in every particular: a site that contradicts the file is worse than no site at all.
- Cost to correct: about ten minutes and often less than ten dollars. A domain registration runs roughly ten to fifteen dollars a year at any of a number of established registrars, and first-year promotions below a dollar are common. Maintaining an email account on that domain is a few dollars a month, depending on the plan. The figures are stated because they remove the explanation. A party presenting a hundred-million-dollar transaction from a free address was not prevented by cost or by time,.
- Owning the domain is only half of it. The address then has to appear on the documents — letterhead, signature blocks, engagement letters, contact schedules and every party’s details throughout the file. Find and Replace in Microsoft Word will often do it in seconds.
Registrar, mail host and web host
Three different services are involved. They can be bought from one company or from three.
- Registrar — registers the domain name and renews it. The registration record — date, time and payment instrument — is held here. Required.
- Mail host — stores and delivers mail for addresses on the domain. Required.
- Web host — serves a website on the domain. Not required for mail.
The domain should be registered in the name of the entity that will use it, in an account that entity controls. Mail is added to a domain in one of three ways:
- Mail from the registrar. Many registrars sell mailboxes for the domains they register, set up in the same account.
- A separate mail provider. A business plan from a dedicated provider — Microsoft 365, Google Workspace, or an encrypted provider — connected by entering the provider's DNS records at the registrar.
- Mail included with web hosting. Most hosting plans include mailboxes, created in the hosting control panel at no extra charge once the domain points to the host.
Whichever route is used, the provider supplies the DNS records to enter. They include SPF, DKIM and DMARC, which let receiving mail servers confirm that mail from the domain is genuine.
Getting it done
There are three ways to get an email address in your own business name. Choose the one that suits you.

1Do it yourself
About $10 to $15 to start
If you can buy something online, you can do this.
- Buy a name for your business on the internet. This is called a domain — for example yourcompany.com. Companies such as IONOS and GoDaddy sell them. First-year prices are often very low: on 25 September 2026 GoDaddy was advertising a .com name for $2.99 for the first year (new customers, with a promotional code). This is not an endorsement of any company. Shop around and compare, and expect the price to go up from the second year.
- Add email to it on the same website. Look for a button that says Email or Professional Email. Choose a name such as yourname@yourcompany.com.
- Use the new address everywhere. Put it on your letterhead, your signature and your documents.
If your business already has a website, you may be able to make email addresses on it at no extra cost. Ask whoever looks after your website.
