Domain and Business Email Setup Checklist

A polished website on a random free address rarely builds the same trust as yourbrand.lk with matching email like [email protected]. For Sri Lanka SMEs—shops, clinics, agencies, hotels—the domain and mailbox are part of how customers decide you are real.

This checklist walks through registering a domain, pointing it correctly, and launching business email without the usual DNS confusion. Follow it in order; most “email not working” problems come from skipped steps.

Before you start: decide ownership and naming

Pick a name you can live with

• Prefer a name that matches your brand and is easy to say on a phone call
• Check spelling variants customers might type
• Avoid names that are hard to pronounce in Sinhala, Tamil, and English conversations
• Confirm trademark/brand conflicts at a basic level before you print signage

Common extensions for local businesses include .lk and .com. Choose based on brand strategy and availability—not panic. You can often register more than one and redirect extras to the primary site.

Decide who owns the accounts

Document:

• Registrar login (where the domain is purchased)
• Hosting / DNS login
• Email admin login

Use a company-owned email for account recovery—not only one employee’s personal Gmail—so access survives staff changes. Store renewal dates on a shared calendar.

Part A: Domain registration checklist

1. Search availability for your primary name and obvious typos you may want to defend.
2. Register with accurate registrant details you can prove if needed for transfers or disputes.
3. Enable registrar lock (clientTransferProhibited or equivalent) after setup to reduce hijack risk.
4. Turn on renewal reminders and, if appropriate, auto-renew with a valid card/invoice process.
5. Note the expiry date in accounting/ops—not only in someone’s WhatsApp chat.
6. Avoid burying domains under a personal account you cannot access later.

If a reseller or agency registers the domain for you, get written confirmation of ownership and transfer credentials. The domain is a business asset.

Part B: Connect the domain to your website (DNS basics)

DNS is the map that tells the internet where your domain should go.

Typical website setup:

1. At the registrar, either use the registrar’s DNS or point nameservers to your hosting DNS.
2. Create an A record (and often AAAA if IPv6 is used) for the site IP—or follow your host’s exact instructions.
3. Add a www record (CNAME or A) so both yourdomain.lk and www.yourdomain.lk work.
4. Wait for propagation. Changes can be quick or take hours; plan launches accordingly.
5. Install SSL/HTTPS so browsers show a secure connection. Most hosts offer free certificates once DNS points correctly.

Redirects and canonical preference

Pick one preferred version (with or without www) and redirect the other. This keeps SEO signals tidy and avoids duplicate-content confusion.

Common Sri Lanka SME pitfall

Changing nameservers without copying existing email DNS records can take email offline even if the website looks fine. Before you switch DNS, export or photograph current MX/TXT records.

Part C: Business email setup checklist

You generally choose one of these paths:

• Email mailboxes bundled with hosting
• Professional suites (e.g. Microsoft 365 or Google Workspace)
• Specialist email hosting separate from the website

For a growing team, separating web hosting and email often means a website outage does not stop invoices and customer replies.

Mailbox setup steps

1. Create mailboxes you need first: info@, personal name addresses for key staff, and maybe billing@ or support@.
2. Set strong unique passwords; enable 2FA on the email admin panel when available.
3. Add the domain in the email provider’s admin and verify ownership (usually a TXT record).
4. Publish MX records exactly as the provider specifies (remove old MX records that conflict).
5. Add SPF (TXT record) so receiving servers know which systems may send mail for your domain.
6. Add DKIM keys from your provider (another TXT/CNAME set).
7. Consider DMARC (TXT) once SPF/DKIM are correct—start with a monitoring policy if you are new to it.
8. Set up devices: phone mail apps, Outlook/Thunderbird, and webmail bookmark for travel days.
9. Configure a clear From name (“Amaya at Brand” beats a raw address people do not recognise).
10. Create a simple signature with phone/WhatsApp and website—keep it lightweight for mobile.

Test before you announce the address

Send and receive tests:

• To Gmail/Outlook and another local provider if you can
• Check spam folders for your own first messages
• Send from phone data, not only office Wi-Fi
• Confirm calendar invites or attachments if your workflow needs them

If mail lands in spam, fix SPF/DKIM/DMARC and content issues before printing the address on every leaflet.

Part D: Security and operations (do not skip)

• Recoverability: store admin logins in a password manager shared with owners
• Aliases vs mailboxes: aliases can forward; not every address needs a full paid seat
• Offboarding: when staff leave, disable login and reassign mail access the same day
• Malware/spam: never install random “email booster” browser extensions on admin machines
• Website forms: if the site sends mail, align SMTP with your provider so contact forms do not fail silently
• Backups: export critical mail or keep important threads in your CRM/process—not only on one phone

Part E: Go-live day checklist (print this)

• [ ] Domain renews under a company-controlled account
• [ ] Nameservers / DNS documented
• [ ] Website opens on HTTPS for apex and www
• [ ] MX/SPF/DKIM (and DMARC if ready) verified
• [ ] Test emails sent and received on phone + desktop
• [ ] Old temporary addresses redirected or retired
• [ ] Team knows who manages renewals
• [ ] Website contact page shows the new professional addresses
