No matter what people say and how many new communications are developed, email continues to be the main mode of communication, especially in the business world. Almost everyone has an email, but they may not have a common chat application. It unifies us and connects with people across the world with just a click. According to Statista, around 306 billion were exchanged every day globally in 2020, and this figure is expected to reach 376 billion by 2025. This clearly shows that email is not going anywhere soon, and the reasons justify its existence clearly (which we will cover in the next section).
Why Do Businesses Need to Send Emails?
Emails have transformed the business world by eliminating communication barriers between customers. As a result, they can easily share information with stakeholders and clients effectively and instantly irrespective of their location on the global map. From small and medium-scale businesses to enterprises, all use emails even if they incorporate other channels like messaging apps, chats, Slack, etc. It has become a notion that every business must be using an email address. Hence, when someone wants to reach out to a company, they prefer communicating with them via email at first. It’s a common mode of communication and probably the easiest one. This is why every business such as eCommerce, SaaS, forums, healthcare, etc., uses a valid, active email address to execute smooth business communication.
Emails look professional, and they are great conversation starters They are cost-efficient. Even if you use a business email, the cost incurred is relatively lower than call charges, especially for international calls It works instantly provided both sides have a stable internet connection Emails can be an efficient way to market new products/services, newsletters, send a notification when a user’s subscription plan is about to end, and much more
Talking about business emails, two types of them exist – marketing emails and transactional emails. Transactional emails usually incorporate the data the receiver wants, and they are typically automated notifications. These transactional emails are sent to a recipient in response to a trigger such as user signups, purchase receipts, ‘thank you’ or ‘welcome’ emails, password changes, notifications, and so on. Sending transactional emails is possible by using your server via an SMTP protocol (Simple Mail Transfer Protocol). However, it’s not that ‘simple.’ You need to struggle a lot with formatting the emails while complying with a set of email delivery guidelines, failing to which your email may end up in the user’s spam folder. Using an email API can solve this problem. It does all the heavy lifting by managing those email formatting nuisances and delivery compliance. This is why it makes sense to leverage a managed Email API solution compared to a self-hosted solution to achieve better delivery and reliability.
