Customer.io vs OneSignal

• Managing users, attributes and events. You are easily able to modify any user, based on their ID, and add or remove attributes, assign events to them. That makes it very easy to segment later and to assign them to several campaigns based on behavior. Just a warning: this integration isn't so easy (at least it wasn't for us).
• Creating workflows of campaigns is very easy. You can quickly create behavioral campaigns based on attributes, segments and add elements to the workflow. You can send an email, then wait, then send another, then exit the campaign if they converted, etc. The workflow is easy to configure and very powerful for automation.
• We don't use many email templates (we make them in MJML) but it's very easy to add senders, to change templates and in general to test designs.
• Deliverability works very well, at least for us. It sends emails pretty fast and without issues.
• Exporting is very quick and easy. Importing wasn't a feature until recently, but it works well too.
• Seeing activity it's also useful. In general, logs are awesome (be it of a customer, of activity on the site, email sends, etc.).
• We don't use environments, but it might be very useful for a bigger company.

• Push notifications are very rudimentary. Everything has to be done by hand unless you're sending an extremely simple message.
• A bit too email centric.
• Lacks an ability to schedule messages on a daily, weekly, etc. basis.

• Is still in development: we know OneSignal is still in development and sometimes it takes longer to create or fulfill certain features.
• Payment: payment menu is not at the glance, [and] is just difficult sometimes to find -it is a minor issue.
• Send to certain custom segments through specific OneSignal IDs; you can do it though API doing a GET call with tools like Postman. If this can be done from OneSignal it would be great.
