6 Best Mandrill Alternatives for Transactional Emails in 2022


Mailchimp Transactional Email, previously Mandrill, is a premium Mailchimp add-on specifically designed to send transactional emails.

Mandrill allows you to send messages triggered by events through an API and SMTP relay, monitor email activity, and take action. Mandrill’s API for email connects your website to the capabilities of a transactional email provider that allows you to send automated messages when a specified event occurs.

The Rules Engine offers to define steps to be taken following the sending of an email. You can determine conditions that must be met for an application to forward the event to a webhook and perform additional actions, including setting click tracking or tags, denying messages, and so on.

List of Mandrill Alternatives for Transactional Email

Mandrill is a fantastic SMTP service provider utilized by millions worldwide. But, of the millions, at most 100k users are not satisfied with its minimal limit for sending emails of 25k emails.

It also has a highly complicated pricing system that includes the idea of credits and blocks for email delivery, which could be a real issue!

1. Mailgun


Mailgun is an exclusively automated transactional service for email. It’s the ideal Mandrill alternative for users who do not require email marketing services.

The extensive set of APIs Mailgun lets developers and tech-savvy marketers develop large-scale delivery infrastructure. In addition to SMTP relay, Mailgun includes functionality for creating webhooks, inbound email routing, tracking emails and analytics, and more.

Be aware that the tool was developed for developers, and the training curve is steep for non-technical people. The inability to support exporting logs or keep them for longer than 30 days should also be considered. If you’re trying to monitor the performance of your transactional emails, Mailgun isn’t the best alternative.

2. SendinBlue SMTP


SendinBlue SMTP is a popular relay service provider typically used for sending marketing and transactional emails and SMS. Additionally, SendinBlue also lets you monitor different email campaigns and provide information on open rates, click rates, bounce, and more.

3. SendGrid

Similar to Sendinblue, SendGrid is an all-in-one platform for marketing emails. The transactional email service is just one of the features that you can access within the tool.

However, SendGrid is considered the world’s most popular marketer and transactional email service due to its robust REST API and SMTP.
