8 Most Reliable Mandrill Alternative SMTP Relays

by | Feb 23, 2023 | Amazon SES, Best Practices, Blog, Comparison, Dyn, ElasticEmail, LeaderSend, MailGun, Mandrill, SparkPost, Transactional Emails | 31 comments

Email service provider MailChimp recently made a move that Mandrill, email delivery API used to send transactional emails by developers will become an add-on for monthly paid MailChimp accounts.

Regarding this announcement we wrote a blog post on Mandrill Alternative SMTP Relays where we discussed the expected changes and impact on existing transactional email users.

As Mandrill merger with its parent company “MailChimp”, here are few repercussions to be expected:

  • Mandrill will not be a free standalone transactional email marketing solution
  • Users need to have a monthly paid MailChimp account if they are to use Mandrill as a transactional email marketing solution
  • The privacy policy has been changed accordingly and resulted in enabling MailChimp to snoop Mandrill users activity data, if they wish so
  • MailChimp is trying to force its paid email solution to the loyal and long-standing Mandrill users which they neither require nor intend to use

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.

Some users utilized the Mandrill free service for unlawful 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.

    SparkPost is a new Scammer in the place of Email Marketing.

    They canceled our account only 48 hours after payment claiming that our complaint rate was too high.

    Out of 27.000 emails sent, we had 150 bounces = 0.5% which is a very low bounce rate in any given industry. (we have made a screenshot showing these data).

    The way they communicate with us is like a Police Investigation, or even worst since they assume clearly that you are guilty!

    On Top of this, You can see on the Home Page of their website that they use very poor Marketing Pratices : Welcome Mandrill Customers! Here’s your migration guide. They want to take over the customers of Mandrill, their main competitor, with agressive Marketing.

    Don’t be fooled by their low prices, there is NO service behind, and they use scammer practices
