Start with OfficialMail
Follow this sequence to create an address on your company domain and connect receiving, sender authentication, and AI summary relay.
Choose how to operate
First decide how you need to operate email
Primary mailbox
A solo business owner
Create a memorable primary address such as admin, contact, or cs, then test receiving immediately.
Domain connection
A team with a brand domain
Use the same domain as your website for email to strengthen trust in inquiries, quotes, and partner communication.
Team mailboxes
A company with team members
The primary administrator manages billing and the domain, while each member configures their own mailbox and AI features.
AI relay
Teams that cannot miss important mail
On the Growth plan, incoming mail is summarized per account and sent to a recovery address; replying there relays the response to the original sender.
Domain connection
Choose the address and find where DNS is managed
How to enter the primary address
Enter the part before @ separately from the domain
contact@mydomain.comTo create it, enter only contactas the primary address. The @mydomain.comis added automatically from the domain entered earlier.
Check this first
The registrar, website host, and DNS provider can be different
The registrar is where you pay for and renew the address; web hosting is where the site or app runs. The DNS provider controls where visitors and mail are routed. Enter OfficialMail records at the service currently managing DNS.
Domain registrar
Where the domain is purchased and renewed
Gabia, Whois, GoDaddy
DNS provider
Where website and mail records are entered
The provider operating the current nameservers
Web hosting
Where the website actually runs
Imweb, Firstmall, Vercel, Railway
How to find it if you are unsure
- 01Check the current nameserver addresses in your registrar dashboard.
- 02If nameservers contain gabia, cafe24, whois, or imweb, use that provider's DNS dashboard.
- 03If you only added A or CNAME records for the website, DNS usually remains with the registrar.
- 04If still unsure, ask support: “Where can I add MX and TXT records for this domain?”
Provider-specific settings
Open the DNS menu of your current provider
These paths apply when you use that provider's nameservers. If menu names changed or direct entry is unavailable, use the official guide or support.

Use this path only if the nameservers were changed to Imweb
FirstmallStore hostingFirstmall Support → 1:1 inquiry → Send the domain and MX/TXT values
If no direct entry menu exists, ask Firstmall to register the records
Once you find the DNS panel, copy the domain-specific records from OfficialMail. MX routes incoming mail; SPF, DKIM, and DMARC provide sender authentication and anti-spoofing policy.

Check connection status
DNS records
Register MX, SPF, DKIM, and DMARC exactly as shown
| Type | Host | Value | Priority | TTL |
|---|---|---|---|---|
| MX | @ | mx1.officialsite.kr.Routes incoming mail to the OfficialMail server. | 10 | 3600 |
| TXT | @ | v=spf1 include:mx1.officialsite.kr -allLets receiving servers verify that OfficialMail is authorized to send. | - | 3600 |
| TXT | dkim._domainkey | v=DKIM1; k=rsa; p=[public key shown on the domain setup screen]The public key differs by domain. Copy both host and value from the domain setup screen. | - | 3600 |
| TXT | _dmarc | v=DMARC1; p=none; rua=mailto:dmarc@officialsite.krDefines how authentication failures are handled. SPF and DMARC remain checked even when DKIM is disabled. | - | 3600 |
These are the standard formats. DKIM keys differ by domain, so use the exact host and value shown in OfficialMail. If your DNS provider does not support @, leave the host blank or enter the root domain.
Using the mailbox
After connecting, test the real receiving and sending flow
- Send a test message to the primary address and confirm receipt.
- Confirm that moves among Inbox, All Mail, Spam, and Trash appear immediately.
- Use importance, unread status, new-window view, and display options to fit your workflow.
- When forwarding or replying, the original body is loaded from the server rather than placed in the URL.
AI summary relay
Receive the key points before opening the message
AI summary relay is a Growth-plan feature configured separately by each administrator and member.
Enter the summary destination
Register a work Gmail, recovery email, or owner address for notifications.
Turn on relay
When mail arrives, AI sends the key request, concerns, and a suggested reply direction.
Open the original
Use the original-message button in the summary to open the OfficialMail body directly.
Reply relay
Replying to the AI summary relays the response to the original sender.
Team operations
Separate administrator and member permissions
Primary administrator
Manages domain connection, billing, subscriptions, and member creation or removal.
Member
Configures their own mailbox, AI relay, and scheduled sending.
Growth plan
When the domain has the Growth plan, members can use paid features as well.
Scheduled sending
Manage recurring mail in the scheduled list
Add recipients to the queue and save a subject/body set to send them sequentially at the chosen interval. Completed recipients remain in the log and can be added again as new queue items. Each Growth-plan account configures this separately. The first send starts one minute after enabling, then queued times are recalculated from the selected interval.
External integrations
Choose IMAP when connecting Outlook
Integrations are configured per account on the Growth plan. When adding OfficialMail to Outlook, choose IMAP from the provider list. In Apple Mail or Thunderbird, choose Other account or manual setup, then IMAP.
Choose the correct provider type
- 1. Enter the full OfficialMail address under Add account.
- 2. Open provider selection, Other account, or manual setup.
- 3. Choose IMAP and turn on Show more.
- 4. Enter the table values in the same top-to-bottom order shown in Outlook.
Outlook entry order
Enter the password and server details in this order, then select Continue.
| Order | Outlook field | Value to enter |
|---|---|---|
| 1 | Password | OfficialMail sign-in password |
| 2 | Show more · Use recommended settings | Turn both on |
| 3 | IMAP incoming server · port · security | mx1.officialsite.kr · 993 · SSL/TLS |
| 4 | SMTP username · password | Full email address · OfficialMail sign-in password |
| 5 | SMTP outgoing server · port · security | mx1.officialsite.kr · 587 · STARTTLS |
Sending API
For your own service, copy the API key and request example from Integrations to implement server-side mail. In AI-assisted development, provide this specification to the coding tool to shorten implementation time. AI does not configure everything for you: review generated code and store the API key in server environment variables, never in a browser or public repository.
POST https://mail.officialsite.kr/api/v1/mail/send · Bearer API key · up to 50 recipients per request
GET https://mail.officialsite.kr/api/v1/mail/messages/{messageId} · view delivery status and logs
Troubleshooting
Check the common blockers first
Should I configure DNS in Vercel or Railway?
If only the website is deployed to Vercel or Railway, DNS usually remains with the registrar. If you changed the nameservers, add OfficialMail records in the service now managing them.
DNS still shows a mismatch
Check quotation marks, spaces, and the SPF include value first. Propagation can take 10 minutes to 24 hours depending on the provider.
Mail arrives, but sending trust is low
Confirm SPF matches v=spf1 include:mx1.officialsite.kr -all and keep DKIM enabled. Mail can work without DKIM, but spam placement or rejection becomes more likely.
AI summaries arrive late
Check that relay is enabled and the summary address is correct. If summarization fails, the original is relayed with an error notice, so check whether that message arrived.
A member cannot see billing
Only the primary administrator can access billing, domain connection, and member management. Members use their own mailbox and automation settings.
Which provider should I choose in Outlook?
When adding OfficialMail to Outlook, choose IMAP from the provider list. Outlook is the app; IMAP is OfficialMail's connection type. POP is not supported.
