Considered Both Products
Customer.io
Chose Customer.io
Klaviyo doesn't have all the integrated options that Customer.io has. Braze has all the same features, but have a different pricing model (pay only for users that logged in and not for everything in the account), so depending on the company's needs it might be more suitable.
Chose Customer.io
There are so many ways to seamlessly connect all your tech together so the data stays consistent. I like their pricing model of charging per user vs data stored, like Iterable and Braze do. I also think their marketing is so good and the content they put out are actually …
Chose Customer.io
I found Customer.io much easier to navigate than any of the other email platforms out there, and the pricing is MUCH better as well.

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.

Klaviyo
Klaviyo is well suited for email campaigns and SMS campaigns. It is great for automated campaigns including cart abandonment, browse abandonment, welcome campaign, lost customer campaign, loyalty campaigns, product review collection, and more. It is easy to use and easy to set up all of the above as well as pop ups on your website to collect emails and phone numbers for SMS and special campaigns even. We did not feel it was necessary to use it for direct customer communications about their orders but you could use it for that too if you wanted to, keeping in mind you pay per the number of emails you send out (wink wink).

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 measure the success of email campaigns.
  • 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
  • Customer.io needs to be more known! I don't know why they don't come up as a direct competitor to Iterable and Braze.
  • Their new Design Studio drag + drop tool could be improved with further customization.
  • Reports aren't the strongest - I use Amplitude to do all my Customer.io reporting.

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.

Usability
Customer.io
Customer.io has drag-and-drop functionality for their campaigns that is very fun and intuitive to use. The audience build functionality strikes the right balance between usability and meticulousness. They also have an array of actions -- time delays, time windows, waitUntils -- that allow you to customize the timing of messages.

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

Alternatives Considered
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.

MailChimp was adequate for basic email marketing, but Klaviyo offers a far superior experience with its advanced segmentation, automated flows, and deep integration with Shopify. Klaviyo’s behavioral data analysis and A/B testing provide more precise targeting, while its robust reporting tools help us understand customer preferences better. Overall, Klaviyo’s features are more tailored to our needs, making it a more powerful and effective platform.

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.

  • we have grown our revenue significantly without increasing our spend. This is critical.
  • retention rate has gone up tremendously with specific campaigns and audience targeting
  • would love to personalize more but we are a small team and struggle to do as much as we could. It would be great to have an account manager who could make account based recommendations
