Acquired by Twilio in 2018, SendGrid has been on a mission to revolutionize customer engagement and marketing automation. But what makes it stand out from the crowd?

SendGrid’s email editor is one of its standout features. Whether you’re customizing a template or building a newsletter, SendGrid makes it a breeze. Plus, its analytics provide insights into customer behavior, tracking everything from basic metrics to message opens by location.

Simple triggers allow you to create high-impact email automations, helping you automate recurring emails and create time-based drip series. This means more personalized, timely emails with less effort.

The signup forms offered by SendGrid are a great way to grow your subscriber list. By capturing new signups, confirming opt-ins, and adding them directly to your email marketing campaigns, you can ensure a steady stream of new prospects for your business.

Lastly, SendGrid’s integration with Twilio Products and APIs allows you to extend your customer communications across multiple channels, providing a unified platform for all your communication needs. This means more ways to reach your audience and more opportunities to engage.

However, no tool is perfect, and SendGrid is no exception. Its contact management, segmentation, and autoresponder features could use some beefing up. While it does offer some automation and segmentation capabilities, they might not be sufficient for marketers looking to create highly tailored and complex campaigns.

Usability also needs to improve. Finding that feature can feel a bit like a treasure hunt, with most functionality tucked away under the “marketing” menu.

SendGrid’s Pricing

SendGrid offers three pricing tiers:

  • Free Plan: Allows up to 6,000 emails per month to a maximum of 2,000 contacts. Includes basic features like automation and segmentation, but lacks live chat or phone support.

  • Basic Plan: Priced at $15/month, it permits up to 15,000 emails per month for up to 5,000 contacts. This plan does not include automation features.

  • Advanced Plan: Starting at $60/month, it enables sending up to 50,000 emails per month to a maximum of 10,000 contacts.



Postmark is a robust transactional email service platform that has carved a niche for itself in the email marketing industry.

The first thing that strikes you about Postmark is its email analytics. It starts with the activity feed, a comprehensive log of delivery events, bounces, opens, and clicks. Stored for 45 days, this data can be extended with a Retention Add-on, ensuring you never lose sight of your campaign’s history.

Dive deeper, and you’ll find detailed reports on every email, recipient, and message event. It tracks when an email was read, by whom, and from where. And if you need to investigate a specific email address, Postmark compiles all its history and activity for effortless access to the full narrative.

For the big picture, Postmark offers high-level reports, allowing you to spot trends and make proactive improvements. If you want to improve open rates for your welcome emails or decrease bounces across the board, Postmark gives you the data to make it happen.

The email delivery services platform also offers a robust email delivery service. It ensures that your transactional emails, which often contain vital details that customers expect to receive promptly, are delivered as fast as possible. This is crucial in maintaining a positive customer experience and avoiding any potential confusion or frustration.

Postmark’s user interface is another strong point. It’s intuitive and easy to navigate, making it simple to manage your email campaigns. Its easy integration feature allows you to start sending emails in minutes, whether you prefer API or SMTP. This means less time fiddling with settings and more time focusing on what matters – your email content.

In terms of scalability, Postmark is more than capable of growing with your business. Whether you’re sending a few hundred emails or hundreds of thousands, Postmark can handle it. Users have reported that the email service provider has helped them scale their email-sending processes effectively, which is a testament to its robustness and reliability.

The platform’s responsive templates are another huge selling point. These pre-made, customizable templates can save you time when putting together transactional emails like password resets and welcome emails. They ensure your emails look professional and engaging, enhancing your brand image.

However, while the alternative to MailGun is a powerful tool for sending and managing transactional emails, it does have some limitations. It lacks some essential email marketing features like personalization of bulk emails, email scheduling, automated follow-ups, and A/B testing. Its pricing structure is also a bit on the higher side compared to some other providers.

Postmark Pricing

Postmark’s pricing is based on the volume of emails sent per month:

  • For sending up to 10,000 emails, the cost is $15/month.

  • For sending up to 300,000 emails, the cost is $245/month.

  • For sending up to 1 million emails, the cost is $695/month.



MessageBird, formerly known as SparkPost, is a powerful email deliverability platform that promises to optimize your emails and ensure they reach their intended recipients.

It provides a unified platform for transactional and marketing emails, allowing you to streamline your email operations and maintain consistency across all their email communications.

Its scheduling and personalization features help optimize email strategies, delivering content that truly resonates with your audience. Advanced analytics and A/B testing tools offer valuable insights into email performance, enabling you to refine your strategies effectively.

Despite its impressive features, MessageBird does have a few drawbacks. It’s not as cost-effective as some other transactional email services, and its sending volume numbers are limited. It also lacks pre-built integrations, which could be a deal-breaker for some businesses.

MessageBird’s Pricing

MessageBird’s pricing is structured around three tiers:

  • Starter Plan: For $20/month, you can send up to 10,000 emails.

  • Premier Plan: For $205/month, you can send up to 300,000 emails. Any additional emails sent beyond this limit will incur overage fees.
