    Customer.io
    This tool is well-suited for companies looking to run email marketing campaigns or send out newsletters regularly to their users/customers. The workflow setup is especially useful for companies who want to send specific emails based on user behavior - i.e. they've not logged in recently, have bought a specific product, haven't opened any emails, etc. This could also be useful for freelancers like me since you can create different workspaces within Customer.io. I have configured it this way to handle email marketing for a few of my clients, and the software keeps everything organized and separate. This might not be the best tool for small businesses, considering the price. It may be better to start out with a cheaper email marketing tool, and then if/when necessary, scale-up with a tool like Customer.io.

    Retainly allowed me to take customer engagement to the next level. I felt an advantage of its low-code functionality, user-friendliness, intuitive automation, and pre-built integrations with a range of other marketing tools. I saw a noticeable difference in my marketing performance and customer retention results after almost 2 months of usage. As a marketer, I managed to automate heavy manual effort to run marketing my campaigns.

    Pros
    Customer.io
    • 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.

    Cons
    Customer.io
    • I may be missing it in the UI, but a place to see the list of emails who qualify for a certain email.
    • One easy to view chart of all our automated/lifecycle emails to see what a given user would see over their customer journey. (This is really just a feature request/idea - the product itself is really awesome.)

    Usability
    Customer.io
    It is really difficult to leverage all the neat features without a developer. I actually think the base software could be really great for a small business if the price is right, but there are so many things you *can* do but have to know how to do them or have access to your website and the ability to code.

    Customer.io
    Customer.io was really the first pure, full-featured drip email program on the market and as far as I know, it's still the simplest and best overall for that specific function. SendGrid has also added drip campaign features, but I would seriously evaluate Customer.io against any other drip email provider because they really have all the key elements you need to make it work.

    Return on Investment
    Customer.io
    • Positive impact on the sales side. I'm not sure about the specific ROI (you have to include the designer and the time it takes to set up) but you certainly get back the investment in a few months, once you are able to scale your email marketing.
    • Customer experience is way better by having more segmented, contextual and accurate messages sent to them.
    • Integration is costly and it will take several days or weeks to be fully achieved. Expect to invest some money on this.
