Considered Both Products
Customer.io
Chose Customer.io
Customer.io has in my opinion more robust features for comms campaigns vs some of the other tools available on the market that have other focuses primarily and then have CRM tacked on. We've also found Customer.io to be more easy to integrate with the tech stack of our business …
Chose Customer.io
Customer.io is much more comprehensive and powerful. It takes some getting used to but once you understand how it works, you have a ton of control when it comes to email marketing.
Chose Customer.io
I found Customer.io much easier to navigate than any of the other email platforms out there, and the pricing is MUCH better as well.
Chose Customer.io
Customer is much more flexible and enables a greater amount of personalization.
Chose Customer.io
Customer.io is one of the tools we use or suggest based on the situation. Customer.io is in a place between basic email marketing and marketing automation (in my opinion). And suits well with clients who wants to advance or start with marketing automation.

It's easy, the price …
Chose Customer.io
We used Autopilot in the past. It worked well but the integration wasn't very good, considering they only used cookies. We have a very complex system right now to be able to track every customer, and it was expensive but worth it. Autopilot worked very well when we were …
Chose Customer.io
I think Customer.io is a unique product. Most of the other email marketing products you'll find are more B2B focused and don't provide a good solution for high volume emails at a low price. If you're a B2C company, I can't think of any email product I'd rather use than …
Chose Customer.io
We do still use Hubspot, but their email automation is very native and fixed within Hubspot. We needed something that was going to collect our events and integrate 2-ways with Segment in order to effectively send the campaigns we desired. There are so many events in our app …
Chose 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 …
Chose Customer.io
because the functonalities and how it is integrated with our Redshift database
Chose Customer.io
Customer.io had the best suite of features and - most importantly for us - was willing to sign a BAA with us so we could maintain HIPAA compliance. Mailchimp was fine but we felt Customer.io had a cleaner interface and was easier for general marketers who aren't dedicated email …
Iterable
Chose Iterable
Iterable's geolocation paired with catalog items was something Braze and other platforms just couldn't do. Many tried to offer a workaround, but there just wasn't a legitimate solution anywhere else.
Chose Iterable
Iterable was more competitive in pricing, the segmentation technology was extremely advanced and fast in comparison with the competitors we analysed, and deliverability and reliability of the system have been fantastic.
Chose Iterable
Iterable has plug-in capabilities with Movable Ink, in which Movable allows for dynamic content to plug into HTML, text, messages, and utilizes data within Iterable to send dynamic personalized content to customers, great tool in addition to Iterable!

Previously we've used …
Chose Iterable
If you're still using SFMC do yourself a favor and explore some of the newer options available. Iterable is a strong competitor unless you need the B2B and account based marketing/support teams all in a single platform.
Klaviyo is great and best for small-medium size companies …
Chose Iterable
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 …
Chose Iterable
Intercom is not created for marketing purposes and it is quite transparent when you get around to building a campaign with it. It's clunky and often quite frustrating to work with. While Iterable is not perfect, it's a tremendous upgrade. Iterable allows you to have more …
Chose Iterable
Iterable is way more user-friendly, eazy to learn and use, overall much better.
Chose Iterable
We have been on Iterable for about 2 years and in that 2 years have evaluated other platforms, considering doing another migration.

The key reason we have stayed with Iterable is the ease of running (largely automated) omni channel comms with a complex data structure. We have …
Chose Iterable
Iterable has more nuance and allows us to leverage more data.
Chose Iterable
Iterable is leagues and bounds ahead of Mailchimp. While they definitely have room for improvement, I'm thoroughly pleased with the creative builder upgrade.
Chose 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 …
Chose Iterable
Iterable has an easier UI, with a great educational center to be up to date on the product. Iterable also helps manage different locales in one template and create different projects to manage different databases. Lately, with the integration with Snowflake, will allow an easy …
Chose Iterable
my company was already using Iterable when i got here. but i will say that the system isn't nearly as complicated as marketo. I found where i didn't like using marketo because of how complicated it is for the user.
Chose Iterable
Iterable has much more flexibility than other platforms I explored. Personalization in particular is something Iterable does better than the competition.
Chose Iterable
Moving from a company that used Mailchimp to one that leverages Iterable was a huge step up. Iterable provides a plethora of additional tools to customize and reach our users in a strategic way. We're also able to automate a lot more in Iterable which saves time and resources. …
Chose Iterable
Far and away, Iterable is easier to use and more cost-effective. While Iterable may not have the bells and whistles or integrations that some of their competitors offer, Iterable can still meet the large majority of business use cases and is easy to use for marketers. As I …
Chose Iterable
Iterable is the best in terms of user interface, innovation and customer service.
Chose Iterable
Very similar capabilities but more expensive
Chose Iterable
Iterable is far superior. The UI, AB testing tool, drag and drop template editor, journey building, reporting. Almost every aspect is better
Chose Iterable
The rich functions , flexibility, iOS and Android SDK integration, Cost and return of investment we find better with Iterable.
Chose Iterable
We thought Iterable provided the advanced features we needed but it did not.

User Testimonials
Customer.ioIterable
Likelihood to Recommend
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 any marketing team looking to ramp up the capabilities on lifecycle marketing specifically if you're a company with a lot of data and/or SKU's the product makes handling a lot of complexities much simpler and enables my team to move much faster even as a small team

Pros
  • Ease of use, a good tool for non programmers, or not so tech savvy people.
  • Great support, willing to help a lot, by chat, calls, or screen sharing.
  • Fast updates, it's a newer tool, but they are coming with fixes and updates fast.
Read full review
  • 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.
Read full review
Cons
  • I may be missing it in the UI, but a place to see the list of emails who qualify for a certain email.
  • One easy to view chart of all our automated/lifecycle emails to see what a given user would see over their customer journey. (This is really just a feature request/idea - the product itself is really awesome.)
Read full review
  • 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
  • Image library

Usability
It is really difficult to leverage all the neat features without a developer. I actually think the base software could be really great for a small business if the price is right, but there are so many things you *can* do but have to know how to do them or have access to your website and the ability to code.

Iterable is super easy to use. I have experience with competing platforms, but Iterable is by far the most intuitive platform to use. I also really appreciate the way the product team is willing to accept product requests

Reliability and Availability
No answers on this topic
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.

Performance

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.

We used Autopilot in the past. It worked well but the integration wasn't very good, considering they only used cookies. We have a very complex system right now to be able to track every customer, and it was expensive but worth it. Autopilot worked very well when we were starting, but then it didn't track purchases, it wasn't easy to change a customer attribute, and so on (this was a few years ago, probably they have improved a lot). It was more visual and better to create huge workflows. . Mailchimp was the first program we used. It's very basic but good at what it does: sending a newsletter to your small database. It has integrated very well with other services and we haven't used in a lot of time, but certainly was grown a lot so it must be doing things fine. I also tried Active Campaign but it was almost the same as Autopilot.

As mentioned previously, I was hired to do a migration from ActiveCampaign, and I stayed for 2 years as a power user of Itearble. Since leaving OneVision Resources, I have continued to volunteer my time in a regional user group, which I would not do if the platform, product, and company were not so strong and so marketer-forward.

Scalability
No answers on this topic
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
  • Helped increase our new user engagement with our cloud-based software
  • Helped our sales team identify clients who had dropped off and stopped interacting with our software
  • Helped our sales and customer service team track which clients were completing their full registration process
  • Helped our marketing, sales, and customer service team identify key features and messaging with A/B testing for different campaigns
Read full review
  • 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.
