The perfect platform to set up product-driven email communications with customers at scale

What I really like is that we use our own database as the single source of truth, and not the email platform database which is never up to date. With Customer.io we use real-time data from our own platform (B2B SaaS) which helps me as a marketer to always communicate with customer segments in the best possible way. Customer.io provide lots of options to filter based on segments and rules which comes in very handy when you want to create cool workflows. Overall, extremely happy with the platform.

Pros

Easy-to-use and intuitive email and marketing automation platform. Especially the ability to send out webhooks makes it very strong.

Cons

The initial set up requires some help from a developer but if you have that sorted out, it's really easy to use.

A very useful tool for non-developer, tech-savvy marketers

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.

Pros

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! :)

Cons

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.

Reasons for Switching to Customer.io

Not enough customization available, more focused on the design than the workflow.

Email automation tool

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.

Pros

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

Cons

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

Extremely handy email communications

An excellent product worth its money and reputation. We use it weekly for external marketing communications.

Pros

I loved its compatibility and easy to use system. You can sign off an email marketing campaign with a few clicks.

Cons

Perhaps its limited design options in some cases, but its automation is still high end.

Great Customer Email Tool - Content Creation Needs Improvement

We have been using Customer.io for nearly three months, and it has revolutionized the way our SaaS business communicates with its customers. From multi-part onboarding of new customers to re-stimulation of lapsed users to announcements of new features, Customer.io has been a dream come true for our subscription business. Building a sequence ("workflow") of emails, triggered by a particular event (like SIGN-UP or UPGRADE or CANCELLATION) is a snap. And applying it to individual customer segments is easy, though you'd better brush up on your logic (AND/OR/NOT etc.) before you construct a more exotic segment. So, too, is the ease of constructing one-time mailings ("newsletters") to an entire group of customers meeting a certain set of criteria. Once the segments are defined, sending newsletters is quite straightforward. In this regard, Customer.io runs circles around MailChimp, which we used to use for this purpose. Integration with a software product like ours is quite straightforward, and Customer.io offers a nice API for updating customer profiles and posting events for those customers. Customer.io currently falls short in the content creation department. Its text editor doesn't measure up to the rest of the application, and requires quite a bit of hand-manipulation of HTML to get newsletters and emails looking just the way you'd like them. Getting email text to wrap around a right-justified image, for example, requires knowledge of and hand-coding in HTML. And even then, the HTML produced by the text editor is not clean. Missing, too, are functions like being able to duplicate a workflow in order to launch a slightly different communication flow to a different customer segment. Onboarding customers to two different product tiers, for example, requires that the entire workflow be created from scratch for each segment, rather than allowing the user to duplicate the workflow and make changes to suit the second segment. Those shortcomings aside, Customer.io is a tool that shows a great deal of promise for any company that wants to communicate on a regular basis with its customers, especially when those communications need to be sequenced over a customer lifecycle. For a recurring-revenue business, where ongoing communication is key to retention and referral, a tool like Customer.io is essential to success.

Pros

- Customer data base is very flexible, and easy to keep up to date via API - Very powerful segmentation tool that can use customer profile fields, events, and even interaction with email to segment customers for subsequent communication - Easy, intuitive construction and management of triggered, multi-part communications workflows - Attractive visual reporting of emails sent, opened, clicked - Reasonably priced, automatic scaling of pricing based on actual volume used (emails, customer profiles) - Built-in A/B testing of email copy

Cons

- Text editor lacks power features; requires HTML in order to optimize emails - Minimal pre-packaged layouts; layout design requires knowledge of CSS - Lack of workflow cloning or replication creates unnecessary work
