Even though at first it might have a longer learning curve (because there are several functionalities we can make use of), I think it compensates having the ability to create complex workflows for email campaigns: there are several functionalities available, and we're always able to create the flows we ideate. I particularly like the “draft” option to test campaigns I've just set up and made live and that we're able to integrate with other data platforms, that enrich our trigger and filter capabilities.Excellent customer support. Even though we're not on the Premium plan, any of the queries we submit are answered within 24 hours and have detailed explanations or workarounds for the issues presented.They also have interesting webinars from time to time, with quite specific topics and tips.

Unfortunately, we're unable to move a contact manually within a workflow; which is particularly important for exceptional cases that we might want to override the rules because of a human or sync error. Another feature I'd like to have (but also seems to be missing from most similar tools), is the ability to have custom reports – though I wouldn't need this very often, thus it's not a dealbreaker at this point.The pricing is somewhat expensive, and we're not able to temporarily downgrade the plan (if by any chance our business has a seasonality).

Extremely positive

The UI/UX is very smooth and clean, and customer service is spectacular. As someone who has used many ESPs, it's very important to me that I can work smoothly without interruptions. In my career, CIO stands alone in UI/UX among competitors. Our account representative is always available for help and consultations, and is always bringing value to our relationship.

It would be nice if there was an out-of-the-box solution for opt-in forms, but it integrates well with our third party app so this isn't a big deal. What they lack here is completely made up for in the quality of their platform and their integrations

I don’t find this product very easy to use but it’s one of the best so far I’ve used in the email automation space.

I liked that I could run my drip campaigns on this tool. The complexity of the drips could be managed.

It requires a dedicated developer which might not always be possible. There should be a few automated codes.

I've tried many marketing automation tools and this hits the spot in terms of what a tech-savvy non-developer can do. There's a fine line between an eye-candy platform that scores low on customization and a fully fledged tool that requires constant support from a developer. Customer.io walks that line gracefully, allowing me to control onboarding and loyalty processes and much more.

I like that I have yet to hit its limitations. Usually if a feature isn't readily available, the platform is open enough for me to find a workaround that gets the job done. Kudos for customer support, a real win! :)

It could use more or better filtering and search options, as the segments, campaigns and attributes can turn into chaos if multiple people use it for different purposes. The learning curve was a bit steep. Except for the quite useful knowledge base and great customer support, I would have enjoyed some video tutorials/onboarding experience.

It's great and does everything we need it to!

The automations are the best part of the software. We can easily create any type of campaign and manipulate it for our needs.

It would be cool if we could just duplicate a workspace entirely with all the segments and campaigns instead of recreating everything. Another thing that would be cool is being able to do a dynamic wait. Or have a queue type of system built-in for webhooks.
