SendGrid vs. Nodemailer: Which is Better? (+ Differences)

This is an unbiased SendGrid vs. Nodemailer comparison guide. You’ll discover why I switched to GetResponse, which is a much better alternative tool that’s easier to use.

SendGrid is a managed email service that is a good choice if you’re looking for cost-effective email hosting for a small team. 

However, you can also use a free open-source alternative, Nodemailer. 

Although both are inexpensive, Nodemailer is free to get started (but a bit complicated) while SendGrid is easy to use but costs some money. 

Truly, Nodemailer is a very versatile tool. It supports a large range of transports and can be extended with plugins. 

The main transport is SMTP, but it can also be extended to use SendGrid, Mailgun, Postmark, and Amazon SES.

Verdict: SendGrid offers a ton of advantages for advanced email marketers. Unfortunately, it’s not ideal for beginners. The major drawbacks are slow customer service, and automation tools that are quite complex to use.

I use GetResponse and recommend it to my audience. Start a 30-Day Free Trial of GetResponse here.

SendGrid Email Service Review

SendGrid email service

SendGrid is an email marketing service. If you’re looking for a simple email marketing tool to deliver exceptional email experiences, SendGrid might be an excellent choice. 

This tool’s drag-and-drop email editor makes it easy to create a campaign in just minutes.

It also provides detailed email performance data and audience insights. Besides allowing you to compare mailbox providers, it also allows you to create custom reports and export data as CSV files.

There are a few drawbacks, though. Although the SendGrid Free plan is great for getting started, it comes with limitations.

You can only store up to 2,000 subscribers and send 6,000 emails per month. Also, the Free plan offers limited signup forms and three email testing credits.

Other than that, it offers all the basic email marketing features. However, if you’re looking for advanced automation, you may have to upgrade to the paid plan.

SendGrid also offers comprehensive reporting features. This dashboard shows key data metrics. You can export data for sharing with collaborators.

Furthermore, you can access metrics and reports related to your email campaigns. 

These metrics can be useful when comparing different mailbox providers. 

The reporting system allows you to analyze your prospects with detailed audience information.

How SendGrid Started

SendGrid is a customer communication platform headquartered in Denver, Colorado. It provides transactional and marketing email services. 

The company was founded by Isaac Saldana, Jose Lopez, and Tim Jenkins in 2009, and was incubated as part of the Techstars accelerator program. 

The three men teamed up to develop a product that helps businesses send email messages to their customers.

Saldana and Lopez both worked at other companies before settling on SendGrid. 

During this time, they hired James Franklin as CEO. While Franklin now oversees the day-to-day operation, Saldana continues to work on product development. 

That means doing things like tinkering with the SendGrid product and seeking out new product avenues.

To build a successful product, it’s important to create a good team. The company’s founders must have a passion for solving a problem. 

The goal of SendGrid should be to provide a solution to that problem. After identifying the problem, they need to find the right team to build it.

SendGrid was acquired by Twilio, a global platform for innovation. Its stock jumped 17% after the announcement.

What is Nodemailer (An In-depth Review)?


Nodemailer is an open-source email service that allows you to send and receive emails from your server. The core module has zero dependencies and is extensible through plugins.

In addition, it has DKIM support, which is useful for encrypting email messages. This allows you to keep your email addresses secure by signing them with a unique DKIM key.

In order to use the service, you must first install the Nodemailer package from npm.

Once installed, you must specify the transport method, such as POP3, SMTP, or SMTP. Once this has been done, you can send emails and get notifications of errors.

Nodemailer also supports attachments. When an email contains a link to an image, the attached image is automatically fetched.

It will then replace the image’s URL in the HTML message with the appropriate cid string. You can also set optional properties for your content, such as a filename or CID.

Nodemailer provides a simple yet powerful email client. It has many options and settings, including HTTPS and DKIM.

It is safe to use and maintain, and you can add plugins to add new features or extend existing functionality. The NodeJS implementation of many APIs makes Nodemailer extremely flexible and secure.

Who is Nodemailer For?

Nodemailer is for anyone who wants to send and receive emails from their server through Node.JS applications.

It can be used by online marketers, entrepreneurs, eCommerce companies, and anyone who’s on a budget — but desires to deliver emails to customers’ inboxes.

Key Features of Nodemailer

  • Sign messages with DKIM
  • A single reliable module with zero dependencies. It comes with easily auditable code and no dark corners.
  • Primary focus on security, no need to deal with RCE vulnerabilities.
  • Easy to use HTML content and plain text alternative
  • Intuitively add attachments to messages
  • Unicode support to utilize many characters, including emojis.
  • Windows support. Installable via npm with Windows just as you would any other module, with zero compiled dependencies.
  • Embedded image attachments for HTML content — prevent your design from being blocked.
  • Proxies for SMTP connections.
  • Secure email delivery via TLS/STARTTLS.
  • Sane OAuth2 authentication

SendGrid vs. Nodemailer: FAQs

Here are answers to some of the frequently asked questions (FAQs) about SendGrid and Nodemailer:

SendGrid vs. Nodemailer: Which is Better?

SendGrid and Nodemailer work with SMTTP, the Internet standard for email. 

This technology has been used extensively for email marketing campaigns and is considered the backbone of email flow on the Internet. The process of delivering emails is very similar to traditional mail delivery.

SendGrid requires you to authenticate with your username and password before you can send emails. 

Once you’ve done this, you’ll be taken to your SendGrid dashboard. From here, you’ll need to set up an API key. This API key is used for sending emails through SendGrid.

Both services support the use of attachments and Unicode. The content type can be a string, buffer, stream, or data URI. 

You can also specify optional properties for the content. For example, you can specify that inline images can be stored, or that attachments are inline.

If you want an easier-to-use email software that functions like SendGrid, then GetResponse should be your next consideration. Start a free 30-day trial today.
