APIs allow two remote entities to communicate in a standardized format. There are hundreds of APIs for various categories currently available, covering everything we do with applications as well as what we program applications to do with other applications. Surprisingly, the fastest-growing category of APIs has been for data sharing and analysis across multiple applications over the last five years, with email service API emerging as one of the most important API services. So naturally, this post aims to discuss ‘why should email services be in API?’. So let’s get started.

Emails are an essential part of running a company. This method of communication is used to communicate with customers, market new products, contact potential clients, and so on. While many other forms of communication, such as social media networks, chatbots, and collaboration tools like Trello and Slack, are now available, email is here to stay. Therefore we need some way to check the vast number of emails currently present in the world.  Hence, the need for an email service API.

There are two types of emails to consider when it comes to business email: transactional emails and marketing emails:

  • Transactional emails usually contain information that the recipient requires or desires, and they usually have automated notifications triggered by user actions. Transactional emails include account creation emails, account notification emails, and purchase receipts.
  • Email marketing contains information to attract, convert, and retain customers. Marketing emails include newsletters, promotions, and advertisements, to name a few.

Why Are APIs Preferred For Email Services?

APIs can be a valuable tool for software developers. Developers don’t have to write new program code every time they try to create an application that does everything. Instead, they can outsource specific tasks by repurposing pre-made pieces that perform better. As a result, the software can communicate with one another via APIs, allowing for the creation of novel and intriguing mashups.

Furthermore, emphasizing modern B2B usage, an application programming interface can be a crucial component in integrating data flows with clients and partner systems. Moreover, companies continue to recognize the potential of extending and integrating application data flows via APIs, allowing for smoother business process integration across applications in conjunction with other types of B2B technology and improving speed, agility, Consistency, and accuracy across multiple industries. However, libraries, third-party packages, and similar tools are challenging to implement.

As a result, an API might be built up of numerous libraries to perform a certain task. On the other hand, a library is not an API in and of itself but rather a collection of helpful techniques or procedures. As a result, an API can do more than a library.

Furthermore, we know that practically all platforms require integration with some type of email provider. Therefore APIs are the ideal option.

Here are some criteria that are a requirement for good APIs:

  • Speed
  • Security
  • Deliverability
  • Ease of use
  • Price

High speed, security, deliverability, ease of use, and reasonable rates can be extremely beneficial and complementary to effective email services. Fortunately, mailboxlayer is an email API that offers all of this to users. Here is an article that helps you understand the common mistakes made by other email validation APIs.
