Step-by-step: Set up email hosting on One.com
Step 1: Pick a plan
Go to One.com. Open Plans and Pricing. Choose an email plan that fits your needs, such as Email Essentials or Email Unlimited.
Step 2: Add or select your domain
Search for a new domain or use an existing one. Complete checkout and verify your account.
Step 3: Open the Email section
Log in to the One.com control panel. Click Email or Email Accounts.
Step 4: Create your first mailbox
Select Create Account or Add Email. Enter the mailbox name, for example info@yourdomain.com. Set a strong password. Save.
Step 5: Test webmail
Visit webmail.one.com. Sign in with your new address and password. Send a test email to a personal address. Reply back to confirm sending and receiving work.
Step 6: Connect to an email app
Open your preferred app, such as Gmail, Outlook, or Apple Mail. Choose Add account. Pick IMAP for full sync across devices. In the One.com control panel, copy the IMAP and SMTP server names, ports, and security settings. Paste these into your app. Save.
Step 7: Improve deliverability
In the control panel, open DNS. Add the recommended records:
- SPF: Authorizes One.com to send mail for your domain.
- DKIM: Signs messages so receivers trust them.
- DMARC: Tells receivers how to handle spoofed mail.
- Use the exact values One.com provides. Save and allow time to propagate.
Step 8: Set aliases and forwards
Create friendly addresses that forward into one inbox, like hello@, press@, or billing@. This keeps your brand clean without paying for many mailboxes.
Step 9: Organize and secure
Create folders and filters in webmail or your app. Turn on two-factor authentication if offered. Rotate passwords on a schedule.
How to connect with popular apps
Gmail
Settings > See all settings > Accounts and Import > Check mail from other accounts or Add another email address. Use the IMAP and SMTP details from One.com. Verify by code.
Outlook
File > Add Account. Enter your email. Choose IMAP. Click Advanced to enter server names, ports, and SSL. Save.
Apple Mail

Best practices for a professional setup
- Use simple, clear addresses: hello@, info@, or firstname@
- Add a plain signature with your name, title, URL, and one call to action
- Keep your inbox clean with rules for notifications and receipts
- Avoid large attachments; send a link to cloud storage instead
- Warm up new addresses by sending a few real emails each day for the first week
Troubleshooting
- Can’t log in to webmail: Reset the mailbox password in the control panel.
- App won’t connect: Recheck IMAP and SMTP settings, ports, and SSL. Confirm the password.
- Mail marked as spam: Verify SPF, DKIM, and DMARC. Avoid heavy images and spammy words.
- Bounced messages: Check error codes. Some bounces mean the recipient’s inbox is full or the address is wrong.
- No new mail in app: Make sure IMAP is selected and the sync interval is not set to manual.
