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.

Well suited for businesses with email and SMS lists who are advertising. Less suited for businesses that don't rely on heavy touchpoints with customers. We find most businesses would benefit from having this type of product but not sure for businesses that don't rely on marketing. We love it so far!

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.

  • Klaviyo helps me to automate the manual tasks with the helps Flows in it which is very easy to use as it has a very easy to understand user interface and no coding reuired.

Cons
Customer.io
  • 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.

Klaviyo
  • At times the platform isn't as intuitive as you would like. Take the time to be onboarded and play around in the platform to get the hang of things. Utilize Klaviyo's resources and attend their live training sessions to help navigate the platform and implement best practices they recommend.
  • Can be pricey depending on company and email list.
  • Customization is limited at times. The brand font we utilized on all branded content wasn't available through Klaviyo. Previously we would have to go through the back end to implement our branded font, import our font, or create content on another platform to utilize our font.

Klaviyo is simply a great solution for e-com email marketing & customer relationship management:
  1. User journey visibility: We can see our clients' customers on their individual user journeys (open email, site visits) to better understand and accommodate your customers.
  2. Flow automation: Creating automated emails that follow up with new leads, those who abandoned carts, purchased.
  3. Email design: So easy to use, and more friendly than some other visual builders that we've used.
  4. Metrics visibility: We can see our clients' metrics very easily and adjust efforts accordingly.

The only reason why I did not give it a 10/10 is that it cannot distinguish purchases that came through subscription recharges instead of purchases that were driven directly by email sends. Other than that, the automation qualities, design features, and segmentation options make this an incredible email platform, and I am very happy with it

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.

Mailchimp was used early in the business when we didn't have as many customers and weren't segmenting. We've used Yotpo for loyalty, reviews, and, most recently, SMS. We have yet to try Klaviyo reviews or SMS, but it would be nice to have all of these items in one suite
