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

I think Sendgrid is a great tool for sending out emails of all types. I've primarily used it for transactional emails as we've had other solutions for marketing emails, but I'm sure it would do just a good job - there is a "Marketing" section within the app you can use. Sendgrid integrates really easily with the development frameworks I've used, such as Laravel and Lumen; I've also integrated it with Moodle with ease.

• 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.

Mailchimp does a good job of documenting the service

It has the potential to be really cool. However, it feels as if it was created by developers for developers (and I work with developers, yet even for me the instrument was somewhat not easy to use - just read SendGrid's help manuals...) However, if you are into data and your way of thinking is more mathematical rather than lyrical, you'll enjoy this instrument

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

If given a choice between the two, I would pick Mandrill over SendGrid. Mandrill is slightly more expensive but the data & reports that you receive from it make the service worth it. Mandrill lets you export reports over a period of time, view the actual content of emails that you've dispatched and the customer support is way better. If you can bear the slightly higher cost, Mandrill would be a better choice.

• 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%.

• Our clients experience significant ROI from their web forms - without receipt of forms, many of them would not still be in business.
• As a solution for clients' sites, we find SendGrid is a fast installation and a 1 stop problem solver, saving us man-hours.
