Corporate Email for SMEs: Complete Professional Setup Guide

Email remains the main communication channel in the business world. A corporate email with your own domain (name@yourcompany.com) conveys professionalism and trust compared to a Gmail or Hotmail account. However, configuring it correctly goes far beyond creating the account: it requires adjusting DNS records, choosing the right client and understanding how to prevent your messages from ending up in the recipient's spam folder.

DNS Configuration: SPF, DKIM and DMARC

If your emails end up in the recipient's spam folder, it is almost certainly because these three DNS records are missing or misconfigured. They tell mail servers worldwide that you are the legitimate sender of messages from your domain.

IMAP vs POP3

When setting up a desktop mail client, you will be asked to choose between IMAP and POP3. IMAP (recommended) synchronises messages between the server and all your devices. POP3 downloads messages to the computer and deletes them from the server.

Summary: Steps for a Well-Configured Corporate Email

1. Choose provider (Microsoft 365, Google Workspace or own hosting)
2. Create the necessary user accounts
3. Configure SPF, DKIM and DMARC records in the domain DNS
4. Configure the email client with IMAP (Outlook, Thunderbird or webmail)
5. Create necessary aliases (info@, contact@, etc.)
6. Check that test emails arrive in the inbox, not spam
