We have developed a streamlined process to help you seamlessly integrate SendGrid into your application, saving you valuable time and resources.

In this blog post, we'll explore how Axon's expertise can simplify the SendGrid integration into your application, ensuring reliable email delivery, scalability, and comprehensive reporting. We'll walk you through the key steps, best practices, and potential pitfalls to avoid, empowering you to leverage the full power of SendGrid integration without the headaches of a complex integration process.

What Is SendGrid?

A global study showed 83% of people prefer receiving business communications via email. Email is one of the most cost-effective channels, yielding $42 for every $1 spent. It also provides precise engagement metrics like opens, clicks, user devices, locations, and browsers.

SendGrid is the leading cloud-based email platform, trusted by over 150,000 companies and developers worldwide. Its powerful infrastructure ensures high email deliverability, provides actionable insights, and scales seamlessly to handle any volume, eliminating infrastructure costs and complexity. Industry giants like Uber, Airbnb, Yelp, HubSpot, CBS Interactive, Spotify, and Pandora rely on SendGrid, which delivers over 200 billion emails annually.

How To Integrate SendGrid Into Your App

Before delving into the programming specifics of SendGrid integration, you'll need to register and set up your account. Please follow the next steps:

1. Create your account on SendGrid. Registration includes verification of email and phone number.

2. Create API Key (Setting -> API Keys). Don’t forget to copy it, as you won't be able to view it later.

3. Create and verify your sender (Setting -> Sender authentication).

To integrate Sengrid into the app on the backend, you need the Java client library. Here's how to set it up.

Add the following Maven dependency in your pom.xml:


<dependency>
  <groupId>com.sendgrid</groupId>
  <artifactId>sendgrid-java</artifactId>
  <version>{latest version from maven}</version>
</dependency>

Now, initialize the SendGrid client:


var sendGridClient = new SendGrid("Your API Key");

Let’s send a test message to ensure that SendGrid integration works correctly:


var sendGridRequest = new Request();
var sender = new Email("Your sender email address");
var subject = "Let's use SendGrid";
var receiver = new Email("Your receiver email address");
var content = new Content("text/plain", "Your content:)");
var mail = new Mail(sender, subject, receiver, content);
sendGridRequest.setMethod(Method.POST);
sendGridRequest.setEndpoint("mail/send");
sendGridRequest.setBody(mail.build());
sendGridClient.api(sendGridRequest);

Using SendGrid Dynamic Templates

SendGrid templates are a powerful feature that simplifies your email logic and enhances customization. Service provides a great UI to manage content including handling params from requests. By using this, you eliminate the need to build the content body on the server side. Let’s go to Email API -> Dynamic templates, and create it. Each template has its own template ID and will apply the subject and body to your email. Let’s check the building mail code example with template usage.


var sender = new Email("Your sender email address");
var receiver = new Email("Your receiver email address");
var mail = new Mail();
var personalization = new Personalization();
personalization.addTo(receiver);
personalization.addDynamicTemplateData("you_var_name", "Value");
mail.setTemplateId("template ID");
mail.setFrom(sender);
mail.addPersonalization(personalization);

Build Content on the Back-End Side or Use Dynamic Templates?

Using dynamic templates will be a better approach for simple emails without back-end related data, in cases when you want to frequently update your template and don’t have the ability to do it with a code base. This will reduce server load and enhance performance. If you don’t want to be linked to SendGrid integration or have complex business logic, prefer to use the default approach of generating content on the back-end side. A great option would also be to use a hybrid of these two methods depending on the specific email, but it requires good technical planning and implementation.

Important Tips About Working With Integration

Seamlessly integrating Sendgrid with your customer relationship management (CRM) system through Sendgrid CRM integration can streamline email communication workflows, enabling personalized and targeted messaging that enhances customer engagement and conversion rates. Here are some important tips about working with the SendGrid integration:

  1. Familiarize yourself more thoroughly and deeply with the API documentation.
  2. Use the full functionality of the service client (attaching files, setting sending time, multiple senders, custom templates) and service dashboard (logs, indicators)
  3. Handle exceptions correctly (invalid sender, wrong template, or reaching limits, etc).
  4. Secure your account and store the API Key in suitable places.
  5. Test your templates and make documentation.

By following these important tips, you can ensure a smooth and robust integration of SendGrid into your application, enabling reliable and scalable email communication for your users.

Conclusion

Integrating a powerful email delivery service like SendGrid can be a game-changer for your application, enabling reliable and scalable email communication with your users. However, the integration process itself can be complex and time-consuming if not approached correctly.
