How Does Web Hosting Work?

Short answer: Business email gives you addresses at your own domain, such as ada@yourshop.com.ng, instead of a free Gmail address. You register a domain, add an email service, create mailboxes, and point the domain's MX records to the provider. Mail then flows to webmail, your phone or Outlook.

The four parts you need#

  1. A domain name. The part after the @.
  2. An email host. The service that stores and delivers your mail.
  3. MX and DNS records. They tell the internet where to deliver mail for your domain. SPF, DKIM and DMARC records prove your mail is genuine and keep it out of spam. Our guide to email encryption, DKIM, SPF and DMARC explains each one.
  4. A mail client. Webmail, a phone app, Outlook or Apple Mail.

How to set it up in four steps#

  1. Register or connect your domain. See what a domain costs.
  2. Choose an email plan and create mailboxes (info@, sales@, your name).
  3. Point the MX records at your provider. If your domain is with Ruachost we can configure this for you.
  4. Sign in on webmail, or add the account to your phone and laptop with IMAP.

What does it cost?#

Ruachost business email costs $2.10 (Basic), $2.80 (Professional) or $4.90 (Enterprise) per month, with 8 GB per account. A .ng domain is extra. See the business email plans.

Frequently asked questions#

Do I need web hosting to have business email?#

No. You need a domain and an email service. Hosting is only needed if you also want a website.

Can I use my phone and Outlook?#

Yes. Every Ruachost plan has Android and iOS apps and supports IMAP, POP and SMTP over SSL.

Will my emails go to spam?#

Not if SPF, DKIM and DMARC are set up. Ruachost supports custom DKIM.

Can my website or app send email too?#

Yes. The SMTP relay lets a site or app send mail from your domain.
