Despite the growing popularity of instant messaging services, Email continues to be an important mode of communication, especially in the business scenario.  In 2023, 4.37 billion people around the globe sent 347.3 billion emails every day. The working of email is fairly simple – when an email is sent, it is initially directed to the Simple Mail Transfer Protocol (SMTP) for verification and storage. If the recipient has a different domain, SMTP communicates with the recipient’s domain name server (DNS) for delivery, handling network issues by queuing or returning undelivered messages.  

SendGrid is a cloud-based SMTP service that helps businesses handle multiple, large and bulk emails.

Let us learn more about SendGrid and its features in this article.


What is SMTP?

SMTP, or Simple Mail Transfer Protocol, is like a digital postman for emails. When you send an email, SMTP helps in directing it to the right place (like Gmail or Outlook) and ensures it gets delivered to the recipient’s email server. It’s the behind-the-scenes system that makes sure your emails find their way to the correct inbox. 

Using a generic or random SMTP service is associated with certain risks, especially for businesses that need to send out marketing mails to potential and existing cusotmers. In such cases, marketing emails can become flagged as spam and end up in our customers’ junk folders. This can be avoided by using a reliable third-party SMTP SaaS. SendGrid is one such application in the transactional email sector, which ensures effective email delivery.

Benefits of SendGrid 

The benefits of using SendGrid for email automation are manifold, driving loyalty through personalized onboarding, improving retention by fostering valued customer relationships, boosting revenue through timely prompts, and prompting desired actions from users already engaged with the brand. 


  1. Lower Cost Outsourcing email to a cloud-based mail server is a more cost-effective solution than maintaining an in-house infrastructure. Considerations include staffing, hardware, software, maintenance, storage, and additional channels like mobile, with outsourcing offering significant savings, especially as the business expands.
  2. Easy Updates: Centralized software updates and configurations streamline the process, eliminating the complexities associated with managing updates across multiple systems. This centralized control saves time and resources, allowing for efficient and hassle-free system-wide upgrades.
  3. Easy and fast implementation: Adding users is easy with cloud-based mail servers such as those of SendGrid. This feature is particularly advantageous for companies experiencing continuous growth and regularly adding large volumes of users.
  4. Resource allocation: By outsourcing email to SendGrid, businesses benefit from the expertise of a dedicated team.

IT professionals can concentrate on product delivery while SendGrid takes care of the email communication.
  5. Scalability: SendGrid offers scalable solutions, allowing businesses to adjust their email infrastructure in response to changing requirements. This scalability is driven by the capability of the email system to adapt to increased workloads and demands.
  6. Flexible payment options: Instead of facing upfront expenses for hardware and software, outsourcing to SendGrid enables a pay-as-you-go model. Companies can pay for the services they need in the present, with the flexibility to scale up based on actual demand rather than projected needs, resulting in immediate cost savings.


Drawbacks of SendGrid

Most users appear to point out two drawbacks in the use of SendGrid. Firstly, the Free and Basic plans, though cost-effective, lack essential features such as marketing automation for over 6,000 emails per month and multiple-user access, requiring businesses to opt for the more advanced, potentially less affordable plans. Secondly, the interface proves non-intuitive for newcomers, with certain crucial features not immediately visible, necessitating navigation through various menus. This lack of user-friendliness can lead to additional time and effort in email management, diverting resources from more critical tasks for users unfamiliar with the platform.


How to setup SendGrid

Here’s a brief guide to setting up and using SendGrid.  For more details, refer to the documentation and guides provided by the developer.


To set up SendGrid, begin by creating an account on the SendGrid website, opting for the free level initially. As your email list grows, you might consider higher subscription tiers for additional features. Once logged in, access the default dashboard view and proceed to “Settings,” then choose “Sender Authentication.” Here, you specify email accounts allowed to send emails. For a custom domain, set up Domain Authentication; for personal addresses like Gmail, use Single Sender Authentication.


To send emails through SendGrid’s API, generate an API key by selecting “Settings” and then “API Keys.” Create a key, define its permissions, and save it securely. Use this key to set up the code for the /mail/send endpoint, either manually or with SendGrid’s Node.js package.

For dynamic content, SendGrid offers Dynamic Templates. Access “Email API” and then “Dynamic Templates” from the dashboard. Create a template, add versions, and use placeholders like {{name}} in the content. Test data can be added in the “Test Data” tab.


Monitoring undeliverable emails is crucial. Track blocks, bounces, and spams through SendGrid’s API or dashboard views. Blocks occur when emails are rejected due to recipient email provider policies. Bounces happen when the email server receives but returns the email. Monitoring spam reports is vital to maintaining sender reputation and ensuring emails aren’t marked as spam by recipients.


Take away

 SendGrid helps businesses effortlessly maintain and expand their customer base. With its user-friendly interface, dynamic templates, and robust campaign management features, SendGrid empowers businesses to craft personalized and engaging email campaigns.  SendGrid can help businesses foster lasting connections with their audience, providing timely and relevant information that strengthens customer loyalty.
