We thought Iterable provided the advanced features we needed but it did not.
Chose Iterable
Iterable is so much easier to understand in terms of the UI and is a joy to use everyday. This is huge especially if you're in the operations/more technical area of the marketing team. Again, the support you get is a huge factor with Iterable!
Chose Iterable
We selected them because of the customer support and easy to get set up.
Chose Iterable
We like the API the most, it seemed the most straightforward, it is easy to update profiles and user traits. Additionally, we use segment and we wanted something that could be a source and a destination in Segment. We also like the identify calls so you can track a customer …
Chose Iterable
The software is extremely easy to use and the campaign section is also very detailed in the way that one can easily use it for experiments. It has made my

Customer.io
This tool is well-suited for companies looking to run email marketing campaigns or send out newsletters regularly to their users/customers. The workflow setup is especially useful for companies who want to send specific emails based on user behavior - i.e. they've not logged in recently, have bought a specific product, haven't opened any emails, etc. This could also be useful for freelancers like me since you can create different workspaces within Customer.io. I have configured it this way to handle email marketing for a few of my clients, and the software keeps everything organized and separate. This might not be the best tool for small businesses, considering the price. It may be better to start out with a cheaper email marketing tool, and then if/when necessary, scale-up with a tool like Customer.io.

Iterable is great for keeping track of all your email campaigns and customers' interactions with emails (if they opened it, etc). This is the only thing I have used it for. It isn't an application for communicating with members , however. I wouldn't consider it a customer support platform. It seems more like an email marketing management platform

Pros
Customer.io
  • Managing users, attributes and events. You are easily able to modify any user, based on their ID, and add or remove attributes, assign events to them. That makes it very easy to segment later and to assign them to several campaigns based on behavior. Just a warning: this integration isn't so easy (at least it wasn't for us).
  • Creating workflows of campaigns is very easy. You can quickly create behavioral campaigns based on attributes, segments and add elements to the workflow. You can send an email, then wait, then send another, then exit the campaign if they converted, etc. The workflow is easy to configure and very powerful for automation.
  • We don't use many email templates (we make them in MJML) but it's very easy to add senders, to change templates and in general to test designs.
  • Deliverability works very well, at least for us. It sends emails pretty fast and without issues.
  • Exporting is very quick and easy. Importing wasn't a feature until recently, but it works well too.
  • Seeing activity it's also useful. In general, logs are awesome (be it of a customer, of activity on the site, email sends, etc.).
  • We don't use environments, but it might be very useful for a bigger company.

  • It is easy to onboard new users with building communications. The drag and drop editor is very intuitive to use.
  • Allows for complex data structures on user profiles and in events. This is a key reason we onboarded to Iterable and have stayed with it.

Cons
Customer.io
  • Push notifications are very rudimentary. Everything has to be done by hand unless you're sending an extremely simple message.
  • A bit too email centric.
  • Lacks an ability to schedule messages on a daily, weekly, etc. basis.

Iterable
  • Locale management: being able to copy and past a template section/row/content from a locale to another. Also, be able to duplicate any locale to any locale. So far we can just duplicate the default locale into the rest of the locales
  • Outages - I feel in the last 1 and half, more outages are happening, impacting their clients

Iterable is there like 99.9% of the time. However, when it goes down, it grinds us to a halt. Most of the time, outages are an hour or less, but if that's at a peak time, it can be a nightmare. That said, when the worst does happen, there are frequent updates and an easy situation tracker that give you an estimate of how much longer you'll have to wait for the issue to be resolved.

The API is super quick. The UI can be a little sluggish depending on what you're loading, but overall Iterable performs great. Iterable appears to do a good job of making processes async so that one action isn't blocking another.

I've never experienced any issues with Iterable. As I and my colleagues have learnt the system and it's features, response to questions and advice from our account manager is always quick. Kevin knows the product well, and with the few tricky questions has hasn't been able to answer he's been quick to get back to us.

Alternatives Considered
Customer.io
Customer.io was really the first pure, full-featured drip email program on the market and as far as I know, it's still the simplest and best overall for that specific function. SendGrid has also added drip campaign features, but I would seriously evaluate Customer.io against any other drip email provider because they really have all the key elements you need to make it work.

Iterable
I can't provide a direct comparison as I have not executed marketing communications with other CRM tools before. Of course, having used Pipedrive as a CRM tool for sales and lifecycle management, I would definitely choose Iterable for complexity and ease of use. The only feature I "miss" from Pipedrive would be, in fact, seeing a pipeline of the customer lifecycle that allowed to instantly see at what point of our app experience the customer was.

We've definitely tested scalability, and it's no line - it works. The process is pretty easy. Most of the times it goes off without a hitch. Any time we do encounter issues, our support team is quick to get on the job and very communicative as they work us through a successful launch.

Return on Investment

  • Removed workload from marketing = more time to make it better.
  • Better contact with specific groups, seeing a increase in sales because of this.

Iterable
  • Iterable journeys save us a ton of time and resources and we are able to optimize messaging with simple A/B testing and dynamic content.
  • Preview data and snippets are easy to use - managing them is less of a lift, saving us time to focus on creative.
