Talking about sending and receiving emails, we cannot ignore how important SMTP Relay Service is. Without the relay service, it won’t be possible to track the sent emails whether they reached their destined recipients or not. The SMTP relay service helps by forwarding outgoing email messages from one server to another until it reaches their destination. 

The SMTP relay service is highly useful for businesses and organizations that need to send a large number of emails. It is not possible to keep track of your email delivery manually. And that is what an SMTP relay service can do for you. 

Apart from that, SMTP relay services include many other services, such as email authentication, spam filtering, and message tracking. 

Now coming to the API integration, the SMTP relay service can be integrated with APIs to enable automated email sending from either web applications or other software systems. The integration can be done using endpoints provided by the SMTP relay service provider. 

But how SMTP relay service can be integrated with APIs? 

How to integrate API with SMTP relay service

API integration with SMTP relay service can be done easily. Start with creating an account in any of your choice of SMTP providers and obtaining the API credentials for authenticating your API requests. Right after that, you must choose an API endpoint from the several API endpoints according to your needs and requirements. You can build an API request using your preferred programming language, including the necessary parameters, such as recipient email address, email subject, email body, etc. 

Once the personalization is complete, send it to the SMTP relay service provider’s endpoint using an HTTP client library or tool. After sending the email, you will receive a confirmation email from the SMTP service provider’s end. And if you don’t, then there will be some errors. Try to find the errors while logging off and return to the account.
