What differentiates Customer.io from other similar products?

It let us replicate the format which is time saving and removes the duplicated of sent emails, with good security in terms of editing or viewing of mails. This tool is also very good for visual content creation are very easy to learn compare to other platforms

What is your favorite aspect of this product?

It is available on multiple platforms with dedicated IP, with highly organized documentation and custom tracking domain. It provides the tracking and reporting of performance and reliability too. Apart from this it provides sufficient customizations to meet business needs, automates the process of the work that needs stepping and grant access to data according to only user role.

What do you dislike most about this product?

For new users, it requires assistance with development knowledge, previous activities can only be seen in the form of downloadable CSV file and reporting system is also not very supportive. It only allows 50 emails at a time, for larger number it takes so much of time. It also offers very few ready to use templates which is time consuming.

What recommendations would you give to someone considering this product?

This offers really easy and rational pricing; this platform is definitely worth recommending for the users with light interface.
