5 Best SendGrid Alternatives for Transactional Email (2024)

Reading time about 12 min

If you’re looking for a SendGrid alternative, you’re probably in the market for a transactional email service. Although it offers other core email features as well, that’s what it’s best known for. 

Transactional emails are very different from marketing ones. Not only can any website or application make use of them, but they also need to be personalized with dynamic contact information to deliver registration info, order details, and password resets. That’s why speed, deliverability, and security are top priorities when choosing an email service provider. 

Let’s look at the SendGrid offering and how SendGrid competitors stack up. 

What SendGrid offers

SendGrid is a large-scale email solution, providing email automation, signup forms, and list management. It’s used by big name clients like Uber and Airbnb. However, it’s best known as a leading transactional email platform offering email Rest API and SMTP (Simple Mail Transfer Protocol). 

SendGrid is developer-oriented and usually integrated into stand-alone applications, rather than used as a SaaS.


  • Email templates with conditional formatting available 
  • Advanced testing options (inbox look, links, spam filter risk)
  • Email validation API available to check email addresses before emails are sent and bounce.
  • Good email delivery rates
  • Monitoring and tools for sender reputation management 
  • Paying customers get chat, ticket, or phone (on higher plans) support
  • Scalable for large-volume operations 


  • They sign you up for ISP feedback so you can remove contacts who complain about your emails from your list. Other solutions save time by automatically removing them for you.
  • Only 3 days of transactional messages history included, 30-day email activity history is a paid add-on.
  • You need other Twilio add-ons for chat, SMS, and push notifications.
  • You need a separate email marketing plan to be able to send other kinds of emails apart from transactional ones. Charges are based on contact list size.
  • You also need this other plan to use a drag-and-drop email editor if you don’t want to code your emails.
  • SendGrid is not a customer relationship management (CRM) platform.

SendGrid pricing

There’s a forever free plan with 100 transactional emails a day. Paid plans start at $19.95/month. Dedicated IPs are available on Pro plan or higher, starting at $89.95/month. Marketing Campaigns plans also offer a free plan (2,000 contacts, 6,000 emails/month) and start from there at $15/month.

Here’s an overview of the prices and main features SendGrid competitors offer as transactional email solutions.

1. Brevo – The best SendGrid alternative

Brevo vs SendGrid

Brevo is the most cost-effective SendGrid alternative. The free plan allows a daily email sending limit of 300 emails, making it the best free SendGrid alternative as well. Now let’s dive into what Brevo offers.

  • All email marketing needs taken care of in one place: bulk email, newsletters, marketing emails, automated campaigns, and every other email marketing use case
  • Not just 2, but 4 options for sending transactional emails
  • Ready-to-use ecommerce plugins for quick and easy integration

  • User-friendly email design tool and templates for marketers who don’t have coding skills
  • Easy use of dynamic content for personalization
  • Preview on different email clients and devices
  • Customer support in English, French, German, Italian, Spanish, and Portuguese

Overall, Brevo is a SendGrid alternative for small businesses that prefer an intuitive way to send transactional emails and want to send all communications from one platform.

API, SMTP, and webhooks

As a SendGrid competitor, Brevo, formerly Sendinblue, offers transactional emails via email marketing API, and SMTP relay. But that’s not all! You can also connect it to all major ecommerce platforms (Shopify, WooCommerce, Magento, PrestaShop) via plugins. Set up automations to trigger transactional emails when certain events occur. Our SMTP server lets you easily set up webhooks and track events.

We understand performance is essential for this type of communication. That’s why Brevo offers detailed email analytics on all key metrics. Plus, it offers the advantage over other email delivery services of keeping unlimited logs (i.e. the history of individual emails sent to each recipient).

Premium deliverability

With over 10 years as a transactional email provider, Brevo maintains 99% email deliverability.

We have a dedicated team of email deliverability experts who monitor sender reputations on our shared IPs to make sure your emails reach the inbox. We also have a strict vetting process to keep spammers out and protect your sending and open rates.

All-in-one marketing platform and CRM

Brevo’s more than a SendGrid alternative for transactional emails. As a CRM suite, it offers a full range of email marketing services and sales tools on one platform. Each service can be used for free (with limited features) from its respective platform; Marketing Platform, Sales Platform, Conversations, and Transactional Email. You can upgrade for advanced tools at any time, allowing you to only pay for the features you need, when you need them.

The Marketing Platform lets you run email, SMS, and WhatsApp campaigns. Need more credits? Brevo’s pay-as-you-go option lets you add credits to any plan.

Grow your list first with signup forms and start sending a newsletter. Then, run a promotional campaign. Confirm each individual order that comes in. After that, automate engagement with tailored offers based on the products purchased. And maybe send a mass email to announce a new product range. Send all your transactional, marketing, and automated emails from one place. 

Brevo also works as a bulk email service. You can use the email API or SMTP to send high-volume marketing campaigns faster and with better results.


Brevo is one SendGrid alternative that takes GDPR very seriously. 

It offers signup forms that make collecting consent legal and managing subscribers’ preferences easy. If someone accepts transactional but not promotional emails, you won’t be able to email them by mistake and annoy them. This protects your sender reputation as you won’t get marked as spam for unwanted communications.

Also, the API syncs contact activity with the contact database in real time. So hard bounces, unsubscribes, and spam complainers from transactional emails are automatically blacklisted so promotional emails are not sent to those addresses either. And unsubscribe links are automatically inserted in all email templates to take one more thing off your plate to remember.

For developers and marketers alike

Brevo as a SendGrid alternative makes transactional email (and not only) accessible to users who are not as tech savvy as a developer. Here are our developer resources but if you’re not one, you can still make full use of the marketing platform. 

First, you don’t have to code your transactional emails. The user-friendly drag and drop email builder lets you create any type of email you want from scratch or customize one of the ready templates available. This way, your transactional emails can be branded and look just as good as the marketing ones. 

With Brevo, customizing your transactional emails with individual information like order status is also easy. Ready-made elements for dynamic content personalization are available in the email editor. 

There’s no need to code your marketing automations either. Just add the steps you want in the visual workflow builder. You can even add transactional SMS or rules to manage the contact based on their behavior, too.

Brevo Pricing

You can activate API or SMTP service even on Brevo’s free account (300 free emails/day). For small business, that means Brevo’s essentially a free bulk email sender.

The Transactional Email paid plan begins at $15/month/10,000 emails. For marketing emails and features the starting paid plan is $25/month/20,000 emails with automation, signup forms, templates, A/B testing, SMS, and no daily sending limit. Note, the Marketing Platform plan email sending credits can also be used to send transactional emails, giving users ultimate flexibility.

2. Mailchimp Transactional Email (formerly Mandrill)

Mailchimp Transactional Email (formerly Mandrill) is another SendGrid alternative for transactional email. It offers a full range of features: dynamic content (merge tags), conditional rules and webhooks to react to specific behaviors, click tracking, and A/B testing. 

However, transactional email is only available as an add-on to Mailchimp’s paid plans.

Mailchimp Pricing

Sign up for the Mailchimp Transactional Email Demo to get 500 emails to test for free. After that, you need a Mailchimp Standard or Premium plan (from $13 for 500 contacts) and add blocks of 25,000 emails starting at $20/month. Price per block goes down as volume goes up but unused email quota doesn’t roll over to the next month. Dedicated IP add-on is $29.95/month.

3. Mailgun

Mailgun is a close SendGrid competitor. It’s an API-first solution for developers or B2B and is often white labeled by other applications. It offers additional email deliverability services, inbox placement, email verification, and transactional SMS as well.

If you’re a marketer, though, Mailgun can be intimidating. 

You’ll probably need developer’s help for sending any email because it’s not done directly from the platform as with email marketing software. At least you have an alternative to creating the emails in HTML. Mailgun acquired Mailjet for email marketing (promotional emails, newsletters, drip campaigns). Now, you can use Mailjet’s drag and drop email builder to create transactional emails as well.

Email log retention is capped at 5 days on the Foundation plan and 30 days on the Scale plan.

Mailgun Pricing

Mailgun offers a trial period of 1 month with a free email sending limit of 5,000 emails. Then, it’s $1/1,000 emails. Paid plans starting at $35/mo.

Dedicated IPs are available on the Foundation 100k plan and up. Validations are an add-on, from $1.20 / 100.

4. Postmark

Postmark is another SendGrid competitor on the transactional side. It’s built as a transactional email service provider for applications so it’s perfect for SaaS, apps, etc. It’s a robust solution for the tech savvy with detailed reporting and 45 days log retention, boasting superior customer support.

But it lacks campaign building capabilities such as list management, contact segmentation, or a user-friendly design tool needed for ecommerce marketing, for example. Only pre-built transactional email templates are available or alternatively you can use their open-source toolset MailMaison with CSS.

Postmark Pricing

Postmark’s pricing starts at $15 per 10,000 emails a month, and you can top up with additional blocks of 1,000 for $1.80 each. Dedicated IP addresses cost $50/month.

Custom log retention can be added to any paid plan to create log periods that are not 45 days. The pricing depends on the monthly email plan you are using.

5. Amazon SES

Amazon SES can be counted as a SendGrid alternative as it’s the most basic solution for service emails. The name literally stands for Simple Email Service. It offers APIs and SMTP, core metrics, and a focus on the tech side as it’s a part of the AWS suite for enterprise. Prominent users are Reddit, Netflix, and Duolingo.

It’s a developer tool, usually integrated into stand-alone applications. And so you can’t log in and simply send your emails from its platform. It doesn’t offer a user-friendly interface or email marketing functionality. It works best if you’re hosted on Amazon too.

Amazon SES Pricing

Amazon SES is often cited as the cheapest SendGrid alternative. This can be true, but keep in mind that price depends on your location, your setup, and hosting. There are no set fees, it’s $0.10 / 1000 emails charged on a pay-as-you-go basis. Dedicated IPs are $24.95/ month.

Choosing a SendGrid alternative

All of the listed SendGrid competitors offer the basic functionality for sending transactional emails. From there, your decision depends on what additional features you need in one email service provider. It’s a good idea for small businesses to try a few SendGrid alternatives for free and see which one’s easiest to use.
