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 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 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 …

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.
At OneVision, I was brought on to migrate from ActiveCampaign and it was a huge improvement to go to Iterable. Much of the improvement lay in the back end connectivity to databases, which although not directly in my purview, made it easier to work as a team (product & marketing) inside our company.
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.
Insights. I think this is the biggest downfall of Iterable, the insights and analytics area is really not good at all. We have almost stopped using it all together in favour of just using Mixpanel (but now we're paying for 2 platforms). Things we can do in Mixpanel that we can't do in Iterable:
- custom conversion windows
- more scalable reports
- comparing multiple events
- setting up alerts that trigger to slack
Segmentation - building segments and organizing lists that are already built.
- relative dates can be confusing but are a critical piece of building lists
- unable to compare multiple events
- we have a pretty good naming structure for our lists but with so many daily users, no good way to organize them (with labels or folders) and searching for a list requires you to find the exact word we end up re creating dynamic lists each time
- static lists don't show you what rules were used to create the list
- no way to see changes over time
Improved ways of collaborating. There's no way of knowing if other people are editing a list, template, campaign or journey. easy to overwrite each other's work
I've been an Iterable user for about 4 years, at 2 different companies. SinceI started using Iterable I think the number of bugs has increased.
I wish Iterable did a better job testing releases so we're not the ones discovering issues so frequently.
In app message. We've had issues with this tool/channel starting at implementation. It feels like it never made it's way out of beta, despite us paying for it now.
The app team offered to do working sessions with us to understand how we use it day to day and never followed up on that. There have been no improvements to the tool and any time we run into another issue with it (although Jena in support is great) it takes forever to diagnose or we are told the issue cannot be replicated. It just feels like we have constant issues with this tool.
We've actually onboarded to another tool (not ideal for omni channel) for some in app messages because this one has so many downfalls and is so buggy.
Self serve documentation is great when you have an idea of what you're doing but not entirely sure. It is not easy to understand for people who are newer or less well versed in the platform.
Customer.io has drag-and-drop functionality for their campaigns that is very fun and intuitive to use. The audience build functionality strikes the right balance between usability and meticulousness. They also have an array of actions -- time delays, time windows, waitUntils -- that allow you to customize the timing of messages.
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.
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 admittedly don't remember much of Klaviyo, as I have become so familiar with Iterable. I definitely prefer Iterable, however. There are so many more features in Iterable and it just feels like a more dynamic and comprehensive experience with more granular data than Klaviyo presented us
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.
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.
