A custom email address helps you create a professional image and boosts your business credibility.
Another important reason for setting up customized email addresses for your business is the flexibility it gives you. For instance, when selecting your custom email address, you can select email aliases for various departments such as firstname.lastname@example.org or email@example.com. This provides more clarity to your customers when they communicate with you as opposed to routing all communications to one free email address. Email aliases will also direct to one inbox so that you can read and reply to all emails through the appropriate alias as well as categories inquiries.
When you have your own custom email addresses you also have full control over them. For instance, you can easily create new ones or remove inactive ones. When a new employee joins your company, you can easily set up one for him or her and create more custom addresses as you hire more staff.
Lastly, getting a custom email address for your business is important because it makes you and your business more memorable in your customers’ inbox. It helps to build a brand. Imagine your customers getting an email from firstname.lastname@example.org instead of email@example.com. Which email do you think they are most likely to open and respond to? With firstname.lastname@example.org, they instantly remember you and your business and can decide quickly whether they want to engage with you or not. Today’s customers are always on the go and are usually pressed for time. Therefore, making the best impression whenever you send email communications to their inbox can really give your business a competitive advantage.
