Domain Name and Business Email Setup Guide

A professional domain and business email are basic trust signals. An address like name@yourcompany.in looks more credible than a free webmail ID, keeps company communication under company control and improves deliverability when set up correctly. This guide walks through choosing a domain, setting up email and configuring the DNS records that stop your mail from landing in spam.

1. Choosing a domain name

• Keep it short and easy to spell. Avoid hyphens and numbers that are hard to say on the phone.
• Pick the right extension. .in or .co.in signals an Indian business; .com is widely recognised. Many businesses register both and redirect one to the other.
• Check trademarks and existing businesses to avoid confusion or disputes.
• Register in the company’s name with a company-controlled email address as the owner contact, never an employee’s personal ID.
• Turn on auto-renewal and registrar lock so the domain cannot lapse or be transferred without authorisation.

2. Choosing an email platform

Most businesses use Google Workspace, Microsoft 365 or the email included with their hosting. Cloud suites offer reliable delivery, large mailboxes, mobile apps, calendars and admin controls; hosting email can be economical for small teams. Our comparison of Google Workspace and Microsoft 365 covers the trade-offs.

3. DNS records you must get right

• MX records tell the internet which servers receive mail for your domain.
• SPF (a TXT record) lists the servers allowed to send mail for your domain. Include every service that sends on your behalf — your mail provider, website forms, CRM or newsletter tool — in a single SPF record.
• DKIM adds a cryptographic signature so receivers can verify that mail was not altered and really came from your domain.
• DMARC tells receivers what to do with mail that fails SPF or DKIM checks and sends you reports. Start with a monitoring policy (p=none), review reports, then tighten to quarantine or reject.

Major mailbox providers such as Gmail and Yahoo now require proper authentication, and bulk senders must have SPF, DKIM and DMARC in place. Without them, even genuine invoices and quotations may go to spam.

4. Mailbox and security settings

• Enable two-factor authentication for every user.
• Create shared addresses (sales@, support@, accounts@) as groups or shared mailboxes rather than sharing passwords.
• Set retention and backup policies so mail of employees who leave is preserved.
• Train staff to recognise phishing and payment-change frauds. See the cybersecurity checklist.

5. Connecting the website and forms

Website enquiry forms should send through an authenticated SMTP service or your mail provider, not the server’s default mail function, so that messages pass SPF and DKIM. Test forms after any DNS change.

6. Moving from free email to business email

1. Create the new mailboxes and verify the domain.
2. Update MX, SPF, DKIM and DMARC records.
3. Migrate old mail and contacts using the provider’s migration tools.
4. Update email addresses on the website, invoices, visiting cards and online listings.
5. Keep the old address forwarding for a transition period.

Frequently asked questions

Should I choose .in or .com?

Both work. Choose the one that suits your audience, and consider registering both to protect your brand.

Why are my business emails going to spam?

Missing or incorrect SPF, DKIM or DMARC records are common causes, along with sending from website forms without authentication.

Who should be the owner of the domain?

The business, with a company-controlled contact email and access shared only as needed.
