Mailchimp Transactional Email (Mandrill) vs. Twilio SendGrid

Any system that requires transactional email message functionality as an external service. The benefits of a well managed and vetted server to maintain reputation as well as being reliability is well worth the effort needed to integrate towards the API specs

If you're prepared to build out your whole staff UX, audience creation, email production, and analytics on your own using API, this tool may have that flexibility. If you require a sturdy drag and drop production tool, this tool has it but at the expense of a lot of other critical functionality. Out of the box analytics/reporting, is extremely limited. Complex queries, even something like pulling those who haven't engaged in email within a certain time period, is clunky. If you require any support at all, this is not the tool for you. I'm a deliverability consultant and have used many of the top email marketing tools and SendGrid has been extremely difficult for my team. I do not recommend it. Shiny and bright during sales, pretty disappointing thereafter.

• Mandrill is extremely reliable. We switched from using a platform that was very hit-or-miss, but we never had a single deliverability issue with Mandrill's transactional API. Every email was sent reliably and quickly.
• Mandrill's reporting and debugging features made it easy to ensure that all our messages were getting delivered to the right place in a timely manner. In fact, Mandrill's tools were so robust that we used it as an end-around way of debugging another failing service we were using.
• Mandrill is a very affordable add-on to an existing MailChimp account. Adding an extra layer of reliability was a no-brainer, and made the cost essentially negligible to our organization.

• Managing email lists / audiences is easy with features like groups and segments.
• They provide pre-built email templates that are very easy to modify. It is also super easy to create new email templates with their drag-and-drop email builder.
• Provides clear / easy-to-read analytics of email campaigns.
• I can easily import large email contact lists all at once or add a user manually one-at-a-time, when needed.

• The rate-limit system can be troubling. If you are switching providers and already have a large e-mail volume, you're going to want to transition slowly. The per-hour send limits are initially very low, and if you have any deliverability or complaint hiccups, they will plummet quickly. The Mandrill support staff is very helpful in this area - they will not (and claim that they can not) manipulate send limits for any account at any time for any reason.
• Billing is combined in with a paid MailChimp subscription, which didn't used to be the case.
• No free tier.

• Not necessarily their Email API but their email in general - they are currently in beta for automated email sequences but are still bare bones. Much more work is needed before it can be used mainstream and be able to convert everything to SendGrid.
• Helping with warming up our dedicated IP for the best-sending score.
• We seem to hit the promotions folder a decent amount (maybe the IP problem above) and even a lot of their emails hit my spam or promotions folder (whether they be transactional or marketing) which isn't a great sign when trusting an ESP.
• Transactional email sequences would be a huge plus.
• Now that Twilio owns SenGrid, having an integrated platform where you could see all our transactional emails together.
• Better reporting and split reporting between transactional and marketing emails.

It did the job for us and we were happy with the delivery rates of the email, analytics and customisation available while integrating it within our platform.

It is usable but needs improvement in overall user experience and ease of use. A new joinee/anyone new to the tool would need more tarining currently before he can use the platform seamlessly. The set-up to value realization time for Twilio SendGrid customers is generally high because of this concern.

I haven't personally reached out to their support team, but the feedback I've heard from our tech support and engineering teams have been that their response to questions has often been they either are unsure or that Mandrill is what it is. For example, when our customers weren't able to see opens and clicks for all emails sent, and we reached out to their support, the response was it is what it is, and they'll send a notification to our app if they can.

Twilio SendGrid Email API is everything we want it to be, and we have no reason to look for any other solution. Features and pricing match exactly what we need. As developers for SaaS products, Twilio SendGrid Email API provides a great service. I hope that they stay this way and don't inflate the service with too many marketing oriented features, because there are other tools for that and Twilio SendGrid Email API is a API for sending email first and foremost.

So we actually work with clients across all of the platforms listed above, but Mandrill has a huge ease of use bonus in its favor, especially when working with clients who are setting up a Cart Recovery style marketing campaign for the first time or are looking for a bit of a fire-and-forget setup. With more sophisticated clients (on the scale of global ecommerce companies), who have a larger subscriber/customer base and in-house design teams, we find that Mandrill usually isn't enough

Sendgrid has a lot of features that other providers have and a few more - like the dynamic template builder, which AWS SES doesn't have. We choose the provider based on the scenario of use and the provider we're using. If we're going to be making regular changes to a template, then we'd go with Sendgrid, as the changes will be easier to make and don't necessarily require developer intervention.

• It helped us to grow our customer database substantially in the last quarter.
• Last week we reached 62% customer engagement in our campaign. This is very good customer engagement for our projects.
• In the last quarter we achieved our target by 135%.

• As it was cheaper than the transactional service we previously used, it saved costs.
• The API was relatively easy to work with so it helped us ship the service and test it quickly.
• We still use the transactional email service, even though we recognize its limits as it meets our immediate needs.
