We use Mandrill for transactional emails. At one point it was its own company, but then it was acquired by MailChimp and even though they are under the same umbrella they are not seamlessly integrated and this makes it awkward sometimes.

We use Mandrill for our transaction mail, which piggybacks on MailChimp for easy template design. Mandrill is very easy to use. It was free until recently, so now we use it with MailChimp.

We are using the Mandrill feature for transactional emails.

We still use the Mandrill part of MailChimp to send transactional emails, as it is integrated in our app.

We have also used Mandrill in the past. It is good as well.

We use Mailgun for email infrastructure. We used to use Mandrill, but we moved to Mailgun because it’s way better.

We’ve used many email marketing tools over the years, such as Constant Contact. We really like the MailChimp branding and found it much easier to use. They also have Marketing Automation tools now. We also use Mandrill to do transactional emails. MailChimp has many different plugins for various purposes.

We are in constant communication with our users through Mandrill and our backend system.

We use Mandrill for our transactional emails. It works and it is easy to use.

We do all of our transactional stuff on Mandrill, but you have to have a MailChimp account to use Mandrill.

We like Mandrill but you have to be careful with how you use it. If your reputation drops, your email throughput will be throttled. Just make sure you send high-quality emails with relevant content and you’ll be good.

The MailChimp/Mandrill merge didn’t bother me to be honest. The only thing they changed was the tracking--it used to be free and now you have to pay for it, but that’s the nature of running a company, you have expenses.

MailChimp is good for our mass market emails. We also manage emails within our app. When you use MailChimp, you get a discount on Mandrill and vice versa. Both are great, especially because you don’t have to be technical to use them.

Through our platform we send a lot of automated emails to our users. The merge hasn't done anything besides make me spend another $20 a month that I wasn’t before. Having to pay for it has made me make sure we are leveraging it as best as we can. But there isn’t anything that’s changed the experience. It’s made people want to look at other vendors like Chicago’s ExpressPigeon. A lot of providers accomplish the same things with more benefits for the same price. People rely on Mandrill so they are reluctant to change, but the merge gave them cause to look around. We’re looking to stick to it in the short-term. We have workflows and automations set on these things for passwords/data reporting; all things part of our day-to-day business would require redoing if we changed from Mandrill. Because of that and other things on our development plate, we haven't explored switching.

We use Mandrill for automated system messages. We had to switch up what we were doing because of the merge, though. Our CTO is looking at it more.

We use Mandrill for transactional emails.

This stack is reliable and affordable.

We like Mailchimp (and Mandrill) a lot. We switched from SendGrid because it is cheaper and has better delivery rates. I have a ton of respect for MailChimp as a company—so partly we just feel good about being their customer.

We use Mandrill a lot. The only downside of Mandrill is that they just changed the plan; now it is coupled with MailChimp and you have to subscribe to both. Since our emails are mostly transactional, we would like to have the ability to choose.

We use Mandrill for our transactional emails and order confirmations. We were using it through Heroku, but they are killing Mandrill as a standalone service so you need to use it through MailChimp. We’re sticking with it, since now I can hook Mandrill into MailChimp for seamless integration.

Mandrill used to be a primary recommendation to the companies in our startup studio, but now that MailChimp is shutting it down, we’re not sure what we will recommend next.

We use Mandrill for transactional emails, like when someone signs up for a service or wants to change something.

For nurturing customer relations, we use MailChimp and Mandrill. We use them for our newsletter and for mail automation tools.

We use MailChimp, Mandrill, Intercom, and Sidekick. When you’re a prospect, Sidekick reaches you. When you’re in the pipe for qualification, you’re reached by Intercom. Once you’re a client, you receive the newsletter via MailChimp and Mandrill.

We use Mandrill for transactional emails and like it for the most part. We have it integrated into our own database, which allows us to see the transactional emails that people have received. It’s also nice that we can see error rates and get alerts, and we like that it’s pretty low-cost.

We like Mandrill for programmatic emails.

We send transactional emails, like daily emails with property updates, via Mandrill. The emails are sent automatically based on triggers like “status”, and “updates”. Mandrill handles unsubscribes really well, it was very inexpensive, and we were using MailChimp already, so it was natural to use Mandrill too. We’ve heard that MailChimp will be integrating the two products more tightly soon, so that will be a nice improvement.

We use Mandrill for product-related emails to our customers. For example, if a customer’s credit card expires, we email them from Mandrill to update their information. We code it all up internally to track from the product side.

Mandrill is good, especially their robust developer resource.

We use MailChimp and Mandrill, and we love them.

We use Mandrill (by MailChimp) for transactional emails. We like it because it’s part of MailChimp, which we already use for email marketing. It’s fairly basic in the way it manages reports and stats, and integrations are non-existent, which can all be challenging. But, even with these limitations, it is comfortable for us to use.

MailChimp is a reliable product. I’ve used other email marketing tools in the past and, thus far, I prefer MailChimp/Mandrill. I do wish Mandrill had better analytics, though.

We use Mandrill for transactional emails, and it’s been great. It’s connected to MailChimp, so I appreciate that I can do something in MailChimp and then easily export it to Mandrill. One downside is that the export doesn’t always work perfectly, and something you do in MailChimp might not translate over to Mandrill.

We also use their transactional email tool, Mandrill, to power non-broadcasts emails and we use it to deliver a custom-built email digest to our members that shows their personalized user activity.

Mandrill is good for transactional emails.

I love Mandrill. It's such a simple API, and it's cheap.

MailChimp is expensive but totally self-serve (which I love), whereas Mandrill is cheap but we’ve had issues with it several times. Overall, we’re happy with both services.

Mandrill is the underlying email distribution service for MailChimp. It's much cheaper, and we've built some of the analytics ourselves.

Customizing different campaigns with Sailthru takes a lot more labor and effort than we would like, and it's a little clunky, but it's far superior to MailChimp or Mandrill, both of which we have used before. MailChimp didn’t have the drip functionality that we needed. Email marketing is a huge component of our business, and we needed a more robust tool.
