1/ Choosing a domain name for business email

To be able to create an email under your company domain name, you first need to have domain name (domain). (In case you don't know, domain-specific email is made up of two parts: the domain name, and the email addresses belonging to that domain.).

Notes when choosing a domain name for your company:

  • Brand matching: You can take the company name or the name of the service or product that you provide to make a domain name, or you can also combine both. However, when reading it, it should be relevant and directly reminiscent of your business. 
  • Easy to read, easy to remember: Since this domain name will be used as both the website address as well as the email address, they should be short and concise, otherwise it will be difficult for customers who need to find you on the internet. If your company has a long brand and product name (or a foreign name) then you may want to consider just choosing the initials (abbreviations). 
  • Should not contain special characters: Domain names containing characters such as dashes, underscores, etc. not only make it difficult for you to communicate to the other party, but also reduce the quality of the domain name. For example, an email with a domain name containing the "-" sign may be more susceptible to spam.
  • Domain name “.com” / “.vn” / “ ….: These are the most popular domain extensions in Vietnam today. If you want your address to be easily searched from other countries because the product is aimed at foreign markets, you can choose the domain name ".com". Otherwise, country-level domains (like “.vn”) are fine and help you rank higher in search in those countries.

Once you have a domain name, the next important thing is to choose the right email solution. Currently on the market there are many email solutions by domain name, diverse in terms of cost, quality and features. However, for ease of visualization and selection, these solutions can be divided into two groups:

  • Traditional email hosting (On-premise): Email hosting is an online email hosting service usually provided by hosting service providers.

You can easily find service plans that allow you to create 50 emails with a total capacity of 50GB for less than 200,000/month. 

However, with this price, users also face many limitations:

    • Capacity: Because of using hosting, the storage capacity of email is also limited because the capacity is not high. With 50GB divided among 10 people, each person can only store up to 5GB. This number is too little for daily email storage, not to mention storing email attachments.
    • Send/receive success rate: This is an extremely important factor that you should consult and consult in many places if you don't want to fall into the situation of ... crying or laughing because email doesn't "go there, get there". There are many factors that affect whether an email reaches the recipient's inbox or is marked as spam.

For example IP address. If the email provider that lets you share an IP address with another business that is regularly reported as spam on the same physical server of the provider, then you will certainly be affected. The probability of traditional emails sent to customers is very high if the administrator does not control well – This is the opposite of Google.

Finally, after choosing the right solution, you need to carefully consider the provider of that solution. Some of the important factors you need to include in your assessment list include:

  • Credibility: This is especially important if you choose solutions provided by foreign units. Large companies like Google or Microsoft often have an authorized partner to provide the service. Instead of buying directly with the company but not receiving an invoice, its partners in Vietnam will stand out to directly support and issue a financial invoice for you. If you choose G Suite (Email Google Workspace) of Google, you can check its list of authorized partners in Vietnam.
  • Service: Good service will ensure a smooth user experience for the whole business. You should carefully study the service reviews of each provider before deciding to sign the contract.

Already have an email system but have a need to switch to a new solution/provider, this factor is even more important.
