Mandrill MailChimp Merger – Hybrid Emails are Future

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 MailChimp, 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 on 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 in 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 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 adapting with this change:

As the email marketplace continues to evolve and in the light of the recent merger of the Mandrill free services with MailChimp paid account, 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. They 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. They have offered a special discount of 10% for the first full month of service in case the account is migrated to SendGrid by 30 April 2016. Moreover, they have also set up a special Mandrill Migration hotline at 1-888-796-4374 and have dedicated a team of sales and support specialists to help users make their transition from Mandrill to SendGrid in an easy, simple, painless and cost-effective manner.

SparkPost is another transactional email service provider with great email inbox deliveries, has also extended their support with 100,000 free emails and wanted to match the price of Mandrill. SparkPost claims, world 25% legitimate emails are delivered through their platform and 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 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.
