What Is a Business Email Address?

Every business address has a local part before the @, which names a person or a role, and your domain after it. The domain is shared by all your addresses; each local part is a separate mailbox, alias or forwarder.

• Person addresses: priya@, priya.sharma@ or psharma@. Pick one pattern and use it for every employee.
• Role addresses: sales@, accounts@, support@, hr@. They survive staff changes and can be redirected to whoever handles that job.
• Standard addresses: postmaster@ is expected on any domain that receives mail, and abuse@ is the conventional contact for spam complaints. Point both at a monitored mailbox.
• Avoid: numbers, underscores and long names that are hard to read out over the phone.

You need a registered domain, a mailbox plan on that domain, and DNS records: MX to receive mail, plus SPF, DKIM and DMARC so receiving servers trust what you send.

1. Register the domain, or use the one your website already runs on; a .in domain is ₹1,000 a year at WebJi® before 18% GST.
2. Choose a mailbox host and create the mailboxes and aliases.
3. Publish the DNS records your host gives you. They look like this:

sharmatraders.in.          MX   10 mail.sharmatraders.in.
sharmatraders.in.          TXT  "v=spf1 mx include:spf.your-mail-host.example ~all"
selector._domainkey        TXT  "v=DKIM1; k=rsa; p=...key from your host..."
_dmarc.sharmatraders.in.   TXT  "v=DMARC1; p=none; rua=mailto:postmaster@sharmatraders.in"

4. Send a message to an outside Gmail or Outlook inbox, reply to it, and check the headers show SPF, DKIM and DMARC as “pass”.

The include, selector and key values come from your mail host; never copy them from an example. Google's sender guidelines require every sender to Gmail to pass SPF or DKIM, and bulk senders to use all three. Step-by-step setup is in the business email setup guide, the records are explained in SPF and DMARC setup and what DKIM is, and you can check your domain with the email authentication checker.

Not fully: the domain always costs money, and free mailbox tiers come with tight limits on users, storage or features. Some hosting plans include mailboxes on your domain, which can be the cheapest route when you already pay for hosting.

What you should avoid is receiving business mail on a domain address but replying from a personal Gmail account. Customers then see two different senders, and your domain's DMARC policy cannot protect replies sent from Gmail. The genuinely free and low-cost routes are listed in how to get a free email domain.
