There are so many ways to seamlessly connect all your tech together so the data stays consistent. I like their pricing model of charging per user vs data stored, like Iterable and Braze do. I also think their marketing is so good and the content they put out are actually …

Iterable had the most robust personalisation features (handlebars, data catalog, snippets, robust segmentation) and multi-language support. Additionally, security features were higher than those of other alternatives. Close follow-up was Braze, and other platforms were compared …

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!

We selected them because of the customer support and easy to get set up.

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 …

Customer.io
Talking from the perspective of a marketer at a SaaS with average. 50K email subscribers, Customer IO has been an excellent tool for us. Our requirements include sending users newsletters, marketing emails, and transactional emails, running lead-nurturing campaigns, and more. For a comprehensive use case like ours, CustomerIO is great. While it also has a learning curve, when you have such requirements, it’s worth it. I don’t think CustomerIO is the best fit if you have basic requirements like only weekly newsletter emails.

Iterable is great for delivering your email marketing activity. We've not yet added other channels (although may do soon), but others report that the cross-channel capability is strong. Iterable manages to find the sophistication to enable our ambitions, yet remain user friendly and manageable. We're on a journey from relying heavily on old-fashioned blast emails to automated CRM. Iterable has been a fantastic tool to help us along the way. I particularly enjoy the journey builder that we trigger in multiple ways, from custom events, to list schedules, and user actions.

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.

  • Customer Journey creation - the platform easily creates a visual path for the marketing team to curate messaging based around timing, channel, behavior as well as add split testing logic and exit criteria so we target only the audiences we want.
  • Customer Success - one of the best teams I've ever had the pleasure of working with. I'm able to move so much quicker because they really create a helpful partnership.
  • Audience segmentation, the platform is easy to work with even if you're a first time user, they do a great job of visually showing the logic and the and/or/none type rules.

Cons
Customer.io
  • Price is quite expensive for Premium or once you get into high volumes of contacts.
  • Depending on how you'll use it, it may require some help from developers to set up.
  • Despite the support being great, you have to email them, there's not chat feature.

Iterable
  • In-app channel, although it works, has some shortcomings in UI functionality or system backend logic, which suggests it is built on an email send-out architecture.
  • Drag and drop editor has its own limitations - it isn't perfect. You can't create some basic designs.

Usability
Customer.io
Super intuitive and easy interface to start off with. There are not a lot of guides and the documentation is helpful but not super extensive, but even if you're a little technical, you can easily figure most of the things out by yourself. Everything is super easy to start with and the platform does not overwhelm you with a lot of options, or data.

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.

My experience with their support team has always been great. Very quick to respond, have an online chat, and are very helpful. They helped me resolve any issues I've had every time in a professional and knowledgeable manner. We've now switched to another tool, and I can't even compare the service level we get there to customer.io

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.

I have previously used Dotdigital, and the way it compares to Iterable is through the reporting capabilities - Dotdigital reporting is, in my opinion, stronger; it provides real-time dashboards and the chance to generate reports for specific timeframes.

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
Customer.io
  • Positive impact on the sales side. I'm not sure about the specific ROI (you have to include the designer and the time it takes to set up) but you certainly get back the investment in a few months, once you are able to scale your email marketing.
  • Customer experience is way better by having more segmented, contextual and accurate messages sent to them.
  • Integration is costly and it will take several days or weeks to be fully achieved. Expect to invest some money on this.

  • I do not have hard numbers, as I am not in the department that deals with those kinds of quantifications of impact. However, I do believe the use of Iterable has been a positive thing for us in providing more comprehensive data that is useful when dealing with customer tickets.
