Wonderful for Transactional Emails, Not as Great for Email Marketing

5 last week New

Comments: Overall, I think all our issues with the platform are because of the way we initially set it up. Customer.io has now added new functionality that fixes most of the issues we've had. They're doing a great job of listening to customers and amending their roadmap accordingly. Overall, think it's got a bright future.

Pros:

My favorite thing is that they recently added functionality to remove duplicate email addresses from sends. Thank goodness!

Cons:

Segmentation is tough. And we set up our account based on customer ID so we have kind of a data mess in there (multiple accounts with the same email address). But as long as you're using it as intended, for customer communications, it's perfect.

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

5 2 years ago

Comments: 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.

Customer.io for Weekly Newsletters

5 last month New

Comments: Overall, very happy with the user experience. It’s saved me a lot of time in developing our newsletter.

Pros:

I love using Customer.io for our weekly newsletters because it allows me to replicate the same format each week. This saves me time each week because I can just make individual tweaks to content each time, rather than having to redo the entire process. I also appreciate the metrics on open and click rate, to know what content sparks our audience’s attention and what doesn’t hit so strongly.

Cons:

I don’t like that it is difficult to copy a message from one “workspaces” to the next. I wish there was a possibility to duplicate a template across workspaces without having to recreate the whole thing. We use different workspaces to separate different audiences, but often want to send them similar emails.

Email automation tool

3 2 years ago

Comments: 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.

Great Customer Email Tool - Content Creation Needs Improvement

4 6 years ago

Comments: 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
