Mandrill MailChimp Merger – Hybrid Emails are Future

by | Feb 20, 2023 | Blog, Email Marketing, Mandrill | 25 comments

Email marketing provider MailChimp has recently made a move that Mandrill will become an add-on for monthly paid MailChimp accounts. Mandrill is transactional email delivery API used to send emails to developers and marketers.

As per Mandrill MailChimp Merger, Mandrill was developed for the specific requirement of sending one-to-one transactional emails to customers, especially by small and medium enterprises and developers.

Mandrill was launched in 2012 and in three years, is being used by more than 800,000 users and has delivered more than 88 billion emails till now.

Transactional emails have evolved in two separate branches:

  • Users who want a service to provide transactional emails as a utility that only delivers emails and that too in an efficient manner
  • Users who want a service to provide smart emails (read personalized and value-added emails) to their customers/subscribers

For transactional email delivery as a cheap and reliable utility service ( the first point mentioned above), there are better services available in the market like Amazon SES, MailGun, nd SendGrid.

Transactional email services are simple and utilitarian providers innovate focusing mostly on increasing efficiency and reducing cost.

On the other hand, personalized emails ( the second point mentioned above) requires expertise in design, a lot more data and is more sophisticated and complex to build. MailChimp has decided to take this second route as they do not want to compete with the process but would rather compete on features.

Moreover, the mechanism to send emails is fundamentally different for MailChimp and Mandrill. Mandrill is a distributed service in which smaller number of one-to-one emails are sent to customers quickly requiring a distributed infrastructure.

On the other hand, MailChimp is an aggregated service in which a set/template of email is loaded on the server and copies of the same email template is sent to a huge number of customers, requiring a centralization of infrastructure to make things more efficient.

In short, this decision of merging Mandrill services with MailChimp is a strategic move to weed out bad accounts and to improve the revenues for MailChimp. There were users who used the Mandrill free service for felonious activities like sending spams.

Also, this strategic decision of Mandrill MailChimp Merger was taken consciously to make sure that small businesses and users who could not afford to pay for a high-end service would move away from MailChimp.

How Developers are adopting with this Mandrill MailChimp Merger

As the email marketplace continues to evolve and in the light of the recent Mandrill Mailchimp merger, several competing entities have pitched in with their support to help Mandrill users migrate to their platforms.

SendGrid is one such product which is a pioneer in the transactional email services category since 2009.

Sendgrid continue to be the market leader in email infrastructure, sending over 23 billion emails a month (3 times the volume of Mandrill).

They offer world-class deliverability, SMTP server, and API integration options in the transactional email services category. They have scale, expertise, and resources to help the users migrate from Mandrill to their platform and be successful in the long run.

SparkPost is another transactional email service provider with great email inbox deliveries. It has also extended their support with 100,000 free emails and wanted to match the price of Mandrill. It claims, world 25% legitimate emails are delivers through their platform. Some of the well know customers include, PayPal, SalesForce, Groupon, Linkedin, Oracle, Comcast, Twitter and many more. SparkPost detail about this announcement is available here.

As a comparison on the new pricing structure, through Mandrill, 25,000 emails can be sent at $20 per month. Now for free, SparkPost allows their customers to send 100,000 emails.

      Yes Bobby; Mandill was available at quite affordable cost and so was used by many for not good reasons. Now Mandrill merged with MailChimp; the cost of Mandrill has also went high.

  5. Katle Richards

    Hmm..this article was not entirely enjoyable. And this is not due to the writer. It took me a long time to understand what are transactional emails. Certain technical terms such as transactional emails are so misleading. I feel the nomenclature for these emails should be Notification emails or Alert emails, or update emails as these emails are generated not to conduct any transaction but to alert the user about the stage of development of his main action initiated (for e.g. the status of shipping of his online purchase)

  6. Rose James

    The inclusion of the Mandrill for the MailChimp accounts is a revolutionary step, it is the most certain that Hybrid emails are the future. To me, efficiency is the most important and this serves the purpose by delivering value added emails.

  7. Ann Garcia

    The foremost advantage of the Integration of MailChimp and Mandrill is that it will allow all the data to be located at one place hence providing huge benefits to both MailChimp as well as Mandrill users! It has also freezed quite a lot of deceitful activities.
