- The integration with our proprietary platform was seamless, and the emails were delivered reliably with very low bounce-rates.
- The UI is clean and intuitive. It's a snap to create custom email templates.
- Their documentation is extremely well made and laid out.
- We weren't pleased when they switched from a freemium model to require that you also use MailChimp; however, MailChimp itself is my preferred email service, so this wasn't a significant hindrance.
- They could have a more robust set of analytics available on-site, as opposed to leaving it to Google Analytics to do the heavy lifting, but it's hard to fault them for not trying to re-invent the wheel here.
Mandrill Review: "A Product worthy of your Transactional Emails, if you don't mind the pricing structure tied to MailChimp"
- Search and Logs of Sent Emails
- Integrations and Client Libraries
- Templates and Merge Fields (almost as flexible as MailChimp)
- API is fantastic.
- Pricing, although fair, is unfortunately tied into MailChimp and not a standalone service anymore.
- Sometimes support is iffy via their ticket system.
- Mandrill is reliable. We rarely find that the information in Mandrill is incorrect.
- Mandrill emails can be tracked from start to finish. We can have full view of the lifespan of an email sent using Mandrill.
- Automation is game changing for our team. The ability to have email action generated from a prompt on our site is awesome!
- We've had moments (very few), where emails have gotten "clogged" up and not sent out. Once the issue was resolved, the emails eventually were sent out.
- Would love to see the metrics made less clunky.
- Kind of a bummer that you can't get Mandrill on its own. You have to buy mailchimp first.
If you have no use for MailChimp, Madrill is a little on the pricey side, since it's not available "a la carte". The interface is a bit clunky, but it gets the job done and is very reliable.
- Dependable - we never encountered down time with the service in the three I developed against it.
- Scalable - our typical use was several messages a second to bursts of 100/s. This level of requests was easily processed by the system. There were rare cases where there were delays of upwards of 10 minutes for messages to be delivered but it was always very rare.
- Well documented - the API has very good documentation. It's a bit quirky in some implementations but the documentation makes it easy to implement.
- Logging - understandably due to the volume of messages the system processes it would be a challenge to log messages older than the current few hours. But it would be ideal if there were webhooks for error events to allow for the creation of custom error notifications.
- UI - A slick admin UI but very limited in some areas.
- MailChimp - it's unfortunate that Mandrill has been brought back from its autonomous state to now being just a part of the large MailChimp suite of email products. I worry it's going to get lost if it's not a part of the MailChimp vision.
Mandrill is used 100% by our engineering department. Most everyone else probably doesn't know what it is or how it works, unless they've heard engineers talking about it.
Our use-case for mandrill is to send transactional e-mails to users as needed across our several platforms. Examples would be email invitations to resources in our application, forgot password/password reset requests, individual account updates and alerts, etc. We also use it to send higher volume marketing messages that are triggered by specific actions taken on our properties. Mandrill makes it easy to integrate to your existing software and send these types of emails quickly.
- Ease of integration.
- Availability of API logs and email send history.
- Email deliverability.
- 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.
Mandrill has got a lot of features that most people will find perfectly adequate. Their deliverability is great, and their management interface (while not visually stunning) provides all the information and configuration options you're likely going to need. For these reasons, it's a good option for most people.
My main complaints have to do with how they changed their billing practices in 2016, removing the free tier, and bundling the service with a paid MailChimp subscription. If you're not already paying for a MailChimp subscription, there are other services that offer 12,000-25,000 emails, per month, for free.
My other gripe is the rate-limit issue. If for any reason users start complaining about your messages, your rate limit (number of messages you can send per hour) will be slashed dramatically. This is for a good reason, but the limits look to be very strict, and they have no issue with taking your account from 10,000 messages an hour to 150 messages an hour. This can absolutely kill a SaaS provider, and they are 100% unwilling to make concessions.
- 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.
- Mandrill used to be a standalone service, but now requires a paid MailChimp account to use. This is unfortunate for users of other email platforms.
- Mandrill's analytics sometimes leave a bit to be desired. The interface is nice and clean, but drilling down into deep analytics can be cumbersome.
- Mandrill lacks a mobile app similar to the ones offered by competing transaction email platforms.
- Enables transactional email sending via MailChimp which opens up a ton of communication opportunities via Order Confirmation, Cart Recovery, or other transactional emails.
- Monitors sub-accounts send reputation and notifies of high bounce/rejection rates.
- Has a very friendly, usable UI and enables smaller companies to dedicate resources to transactional emails without as much setup work as other transactional platforms.
- The platform is now limited to only MailChimp users whereas before it was open to anyone.
- There's not a lot of support for advanced merge tag usage or using dynamic data in transactional emails.
