Modern marketing automation platform with powerful data integration capabilities

5.0 last year

Pros:

As a SaaS company, product data integration was a key decision factor when picking our MAP. Customer.io was by far the best at leveraging product data in emails and became a key part of our workflow to detect and activate leads from Product.

Cons:

The initial setup was quite complex because of what we wanted to do, but the Customer Success rep was very helpful.

Our go-to automation software

5.0 9 months ago

Comments: Overall my team is very happy with the software and we would recommend it.

Pros:

It's very easy to use and does 90% of what you'd need to automate your marketing.

Cons:

Some of the UI choices over time have become worst, like elements covering crucial elements (eg. minimap when editing an email), and their push to become more of a CDP than a marketing software has made the platform more cluttered for those who, like me, want to use it for marketing automation. Lastly, but possibly most importantly, the fact that we still can't DUPLICATE a campaign is absurd. Having to re-create campaign settings each time is such a time waste, for a seemingly obvious (And simple) feature.

Great and quick customer service, broadcast function works well

Pricing doesn't work

4.0 3 months ago

Comments: Customerio is generally fine, but the pricing structure doesn't work for us. Ordinarily, in this situation, we would just go with a different company, but we haven't found one that makes sense. They got us in on their startup program, but that is just a bandaid on their pricing model.

Pros:

It can send emails based on actions triggered within our app.

Cons:

The pricing structure. It assumes clients are B2B businesses, not B2C or e-commerce.

Complete feature-set and excellent support

5.0 last year

Pros:

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.

Cons:

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).
