Professional email

A mailbox using the company’s own domain, such as [email protected], instead of a generic provider’s address.

What it means in practice

Professional email is a mailbox linked to your company’s own domain rather than a generic address. It builds trust in proposals, contracts and business communications, and depends on correct DNS configuration (MX, SPF, DKIM and DMARC) for reliable delivery rather than landing in spam.

An everyday example

A real estate agent sends proposals from [email protected]. After switching to [email protected], proposals arrive with the agency’s name in the address, customers recognize the sender and, if João leaves, the mailbox and history stay with the company rather than with him.

Signs this already matters to your company

• Proposals and payment slips come from a free address
• Every employee uses personal email to talk to customers
• Company email lands in the recipient’s spam folder
• When someone leaves, conversation history leaves too

Frequently asked questions about professional email

Is professional email the same as email with your own domain?

Yes. It is an address ending in the company’s domain, such as [email protected], rather than a free provider’s name.

Why does my professional email go to spam?

Almost always because authentication is missing. The domain needs SPF, DKIM and DMARC configured in DNS, which are the records Gmail and Outlook check before accepting messages.

Can I read professional email on my phone?

Yes. The mailbox can be configured in iPhone and Android email apps, Outlook and the browser using server details supplied by the email hosting provider.
