Excellent segmentation and behaviouring platform

// Cofounder / Marketing, Growth, Technology, Experience at Sensacional Chile

What do you like about Customer.io?

The interface is extremely fast. Segmenting options are very wide, and because you are the one sending the events and the data, the sky is the limit. In our case, we use this only for email (you could use it for SMS or push notifications too). So far the results of our behavioral campaigns (based on custom events on our platform) work incredibly well.

What do you dislike about Customer.io?

It's extremely technical. This means that (1) you need to know very well how to integrate with Customer.io. This is NOT easy and will take some time to a developer. Your platform needs to be able to send events to Customer.io, so prepare to change things on your platform. Also, the fact that using a unique ID and not being able to merge contacts is a pain. We have been changing some things and the way we use Customer.io and this has complicated things, because we have duplicated contacts. Having to send the "created_at" feature is also something that could be avoided.
So far the platform works great, the trigger campaigns are amazing and it's extremely flexible and versatile.
It's a detail, but the fact to not be able to filter in the events by using "property.subproperty" really makes things complicated for segmenting. We want to check if the sale has a value higher than a threshold for free shipping, so we would like to use sale.properties.amount but that is not possible.
Exporting data could be a ton great, right now is very poor.

What have you been using it for and what problems did Customer.io solve?

We use it for sending emails to our customer, we are an ecommerce.
We have it connected with OptinMonster and use it for triggered campaigns based on behavior. That works incredibly well and converts a lot. We also send our newsletters with this software.
It is able to track events and properties across any ID, which makes it very valuable. We had the chance to catch the plans that were cheaper, nowadays it's a bit more expensive ($250 min) for a small startup.
