Customer.io vs. Iterable vs. Intuit Mailchimp

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 a highly robust platform for omnichannel management with advanced personalisation capabilities, and it is among the best in the industry. It does it without being technically overcomplicated, thereby surpassing older industry standards that require developer-level knowledge for advanced personalisation or targeting setups. One thing where Iterable shines is the CSM programs they assign to clients that truly nurture them to reach the full potential of the platform and achieve business goals. There are a few shortcomings here and there, but I haven't seen any platform without them, and overall, the enablement that Iterable allows far surpasses other alternatives.

For any E-commerce related needs, like you need to see a list of customers who have added products to cart but did not purchase, this can be done really easily, but if your e-commerce provider provides integration, then it is best suited. Most of the systems in the Market provide out-of-the-box integration. Their API is also very easy it can be integrated to any language. You can integrate it into your custom developed system and use the features, like adding customers to specific lists. Also, if your lists become really big, then their system can get a bit slow to respond via API, so you might need a strategy for how you are gonna fetch the data using API.

• 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.

Incentivized

• 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.

• Mailchimp allows you to manage your mailing list really well. You can subscribe people, unsubscribe people manage the mailing list directly into segments, and what not.
• Mailchimp has features where you can create campaigns based on your mailing lists and send out newsletters to your subscribers based on a multitude of parameters that you can setup. Such as send email daily, weekly, monthly and they also have event based mails that you can send out.
• Mailchimp also has a feature where you can design your emails. The look and aesthetics are very important when sending emails to your subscribers and all those needs are addressed here.

Incentivized

• 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.

• 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.

• The pricing tiers do scale quickly so if you have a free newsletter it may get expensive
• The pricing is based on total emails so if you have users who you only email rarely it might not make sense to use Intuit Mailchimp
• Customer support can be a bit lacking at times and their docs aren't always the best

Extremely easy to use, deeply integrated into our infrastructure

We've had Mailchimp for about ten years, I want to say. I started with the company about four years ago, and I don't see us ever diverting to another source. It's easy for us to use, and we have all our clients already built into the database. I imagine we'll use them for as long as we have the company.

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 very easy to learn and use. It's a great platform for both a new email marketer and a marketer that's been working in email for 20+ years.

Incentivized

The interface is a bit complicated, and I need to spend some time to learn new functions and understanding how it works. I don't like working with email templates because of the limited customization options. However, functions like AI for generating emails, segmentation, and analytics still work well and are very useful.

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.

Incentivized

I have, in the 4+ years that I've used Mailchimp, never seen an issue that restricted the use of their software/tools. I don't know of a single time when they're system crashed or went down. I could be wrong, but I honestly haven't experienced any issues with outages, errors or unplanned downtime

Incentivized

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.

Incentivized

I haven't noticed any slow speeds from Mailchimp or their tools. I think the landing pages load quickly and look nice. The email reports and editing operates smoothly and doesn't take time to load. Additionally, when I use Mailchimp in conjunction with Zapier + Hubspot I don't notice any drag between any of these tools

Incentivized

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

Incentivized

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.

Website tools were easy to use and understand so a novice can easily meet or exceed their client's expectations! Loved that we were able to totally customize so that the e-mail we created conveyed our client's overall messaging consistent with their branding! Client love that we can provide turnkey services to support their sales and marketing teams!

Incentivized

It's pretty easy to get up and running! There's a slight learning curve on a few things, but once you find where everything is located, you can import your list and send your first email. It really makes our clients feel great to see how quickly they can get that first email out.

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.

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.

I don't think they are comparable; we use Google Ads to put our website at the top of the list when someone googles certain words. We use meta business to manage our social media. Google aims to gain customers, while Mailchimp is used to interact with both existing and new customers.

Incentivized

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.

Mailchimp over the years I've used it has grown in leaps and bounds. They have added so many additional features than were previously available. They are truly an all-in-one marketing platform now. If you're a small operation and just want to add email to your marketing efforts, they're there for you. If you're a larger operation and want to start sending postcard advertisements, they can do that. If you'd good with that and want to kick up your marketing by going social, you can do that on their platform. They are truly able to be as small as you need, but also get quite large in whatever it is you'd like to do through their system.

• 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.

• One of my retail web store clients was sending out email specials and notices about once a month. After clicking the send button, we would watch Google Analytics and the current site users would light up immediately. Often, the current site visitors would pop up to 20, 30 or more after the email was sent. On a normal day, seeing 1 or 2 online users would be OK.
• Pretty much in all cases, we could see an uptick in positive activity after sending out a Intuit Mailchimp email to a list.
