Business email address

Learn what a business email address is, how it builds trust in your brand, and what features to look for when choosing a business email solution.

What is a business email address?

A business email address is an email address that includes your company’s domain name (for example, Using a branded business email address helps to establish credibility, build trust, and promote your brand.

  • Establish credibility

    What does your business email address say about you? Does it set the right tone for potential customers? Using an email address like may sound like a good way to save money and get your name out there, but it lacks professionalism. Plus, messaging from this type of email for business may be misconstrued as spam and get deleted without being read. Establish credibility and help to ensure deliverability with a custom business email address that conveys authenticity and trustworthiness.

  • Try email marketing

    Chances are that there are more people in your audience with an email address than a social media account. A digital marketing strategy includes email marketing campaigns, but they won’t deliver the results you desire unless they come from a business email address. A relevant and personalized message from a recognized brand that matches up with an established domain leads to a higher return on your investment.

  • Build trust

    Customers trust recognizable businesses. Compare a company that answers the phone with “Hello?” with a company that answers, “Thank you for calling ABC Company, this is Jane. How can I help you?” With which one will you share your personal information and credit card number? It’s the same with a domain-based email for business. Whether it’s sales@, hr@, or, business email addresses tell customers and potential customers that you are legitimate and trustworthy, which brings value to your brand.

  • Use alias email addresses

    Show your customers and potential customers that you are professional and organized—use alias email addresses for various departments like sales, support, and HR. In addition to portraying yourself as a larger, well-established business, email aliases help you determine what the correspondence pertains to, even before you open it. Email services for business email accounts typically allow several alias email addresses per user.

  • Promote your brand

    A custom, domain-based business email address means that you are promoting your business’s name—not the name of your free email provider—and it reinforces brand awareness. Easier than printing and handing out your business card to everyone you come in contact with, communicating through a business email address keeps your name in front of potential and current customers and reinforces your brand messaging. A business email account makes a greater impact and is more memorable when promoting your brand.

  • Get website visits

    A business email address will be seen on social media and your business cards and in presentations and marketing materials. Your domain name lets people know you have a website and encourages them to visit for more information. A business email address that correlates with a website reinforces their impression that you are a professional who is serious about your brand.

  • Choosing a business email service

    There are several factors to consider when searching for an email service for your business. Make these a high priority.

  • Security

    Protecting your email accounts and content is more important than ever and trusting a free service for your business email address can put you and your data at risk. Seek an email service for business that scans for incoming malware and phishing attempts and provides information about potential threats.

  • Spam filtering and malware protection

    Insist on built-in tools that detect spam and automatically send it to your spam or junk folder to avoid cluttering your inbox. More importantly, you want a service that protects your business from malicious software (malware) that can create havoc on your computers and mobile devices.

  • Cross device compatibility

    Find a business email account that synchronizes your work—like meetings, emails, and calendars—across desktop and mobile devices. The convenience of picking up where you left off in any application on any device contributes to a flexible working style for you and your employees.

  • Platform migration

    Know ahead of time that you can easily and completely migrate the data from your free email service to a business email service. It is imperative that your email history, contacts, and other important information are safe and accessible when you are ready to work from your business email domain.

  • Business applications

    Ensure that the business email service you choose supports the applications that you use all day, every day. For example, you need the convenience of scheduling a meeting via email and adding it to your calendar with the click of a button, and the ability to call or video chat from your connected apps.

  • Backup and storage

    What good is an email service for your business if you don’t have enough storage space for your emails, recorded meetings, and electronic files? Find a provider that offers plenty of storage space with a secure data-backup plan.
