Considered Both Products
Customer.io
Chose Customer.io
Customer.io has in my opinion more robust features for comms campaigns vs some of the other tools available on the market that have other focuses primarily and then have CRM tacked on. We've also found Customer.io to be more easy to integrate with the tech stack of our business …
Chose Customer.io
Customer.io is much more comprehensive and powerful. It takes some getting used to but once you understand how it works, you have a ton of control when it comes to email marketing.
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.
Chose Customer.io
Customer is much more flexible and enables a greater amount of personalization.
Chose Customer.io
Customer.io is one of the tools we use or suggest based on the situation. Customer.io is in a place between basic email marketing and marketing automation (in my opinion). And suits well with clients who wants to advance or start with marketing automation.

It's easy, the price …
Chose Customer.io
We used Autopilot in the past. It worked well but the integration wasn't very good, considering they only used cookies. We have a very complex system right now to be able to track every customer, and it was expensive but worth it. Autopilot worked very well when we were …
Chose Customer.io
I think Customer.io is a unique product. Most of the other email marketing products you'll find are more B2B focused and don't provide a good solution for high volume emails at a low price. If you're a B2C company, I can't think of any email product I'd rather use than …
Chose Customer.io
We do still use Hubspot, but their email automation is very native and fixed within Hubspot. We needed something that was going to collect our events and integrate 2-ways with Segment in order to effectively send the campaigns we desired. There are so many events in our app …
Chose 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 …
Chose Customer.io
because the functonalities and how it is integrated with our Redshift database
Chose Customer.io
Customer.io had the best suite of features and - most importantly for us - was willing to sign a BAA with us so we could maintain HIPAA compliance. Mailchimp was fine but we felt Customer.io had a cleaner interface and was easier for general marketers who aren't dedicated email …
Kustomer
Chose Kustomer
I think that Kustomer is the most user friendly BUT I think the other platforms are built to do a lot more and can be much more customized
Chose Kustomer
I find it baffling how little data can be stored or associated with a customer in many other systems, and how difficult that can be to set up. It is fine if you already have a robust CDP that you can hook up and use to power your CRM, but it is rare that an organization has the …
Chose Kustomer
It has improved a lot of the training time needed for our new hires to understand the Kustomer interface and how to handle communications fully. The time invested went significantly down, and the learning curve improved a lot as well.
Chose Kustomer
Apps like Intercom, Zendesk, and Gorgios all treat customer inquiries as tickets, just tracking that one issue or interaction with a customer. Kustomer treats each customer as an individual, which allows us to provide top-notch customer service. Customers love that we're able …
Chose Kustomer
Kustomer is more modern and capable of so much more any of my other systems have compared to in technical support customer interfaces.
Chose Kustomer
Kustomer is a great fit for our organization because we can cut down on multiple contacts from the same customer and see all their information in one place. It's also infinitely customizable, so if we need changes made we can make them while still using the same platform. This …
Chose Kustomer
Kustomer is different from slack since Slack is just for communicating with the whole team while Kustomer is more on communicating with our customers.
Chose Kustomer
I have never used anything besides Kustomer and I don't know if I ever will because Kustomer is just so helpful!!
Chose Kustomer
The UI of Kustomer is a lot cooler than what we are using before. There are a lot of features that Kustomer has that make things easier and more convenient than Desk.com.
Chose Kustomer
I use both in my role with the company. Our social media channels are managed through Khoros, but we use Kustomer to notate and contact customers outside of social media. I'd much rather bring our social media channels into Kustomer, to help with efficiency.
Chose Kustomer
I have not had any experience with other programs like Kustomer.
Chose Kustomer
Kustomer has a great team that is easy to work with. They are always there to support and are pleasant, as well.
Chose Kustomer
Zendesk: In my opinion, Kustomer is more powerful when used to its full potential due to its workflows/automations.
Chose Kustomer
Kustomer is far more intuitive, personal, and holistic than Zendesk. As a company who has a lot of interaction with a single customer, it is such an advantage to take the customer approach rather than a single ticket approach. Zendesk was very limited in a lot of the actions …
Chose Kustomer
All other systems I have used have been internally-made programs that were a lot more basic order-taking systems, no notes or call functions outside of when order was placed. Doesn't really compare here.
Chose Kustomer
Kustomer simply does more than any other platform I've been able to work with. Sure some others will give you a handful of neat tricks built in for managing a channel or two but those rarely offer any external integrative capacity or limit what you can do in connections. …
Chose Kustomer
Intercom, Kayako, Zendesk, Freshdesk have all been used by myself in the past, and were evaluated before we chose to go with Kustomer.
Chose Kustomer
I was not personally involved in the decision-making process when selecting a new CRM and ultimately settling on Kustomer. That said, I'm happy with the decision to partner with them. Compared to our previous CRMs, it is much easier to work with everything in one place and we …
Chose Kustomer
Kustomer was better suited to the personalized nature of the service that we're trying to provide.
Chose Kustomer
Glovo was using Zendesk before. Kustomer is much more flexible in terms of integration capabilities and customisation.
Chose Kustomer
Moving from Zendesk to Kustomer was driven by the clarity that the customer timeline brings for advocate engagement alongside the custom workflow abilities.
Chose Kustomer
Zendesk did not give a big picture of the customer. It was more of a ticketing platform, and only gave statistics of those conversations. We were unable to track customer sentiment, or other attributes of the customer.
Chose Kustomer
Kustomer is far more scalable and flexible than Zendesk, and it provides a real omni-channel experience far from the "Zendesk for mails, Zendesk chat for chats" we were used to. On the automation and customisation features, it gets even clearer how Kustomer can deal with a lot …
Chose Kustomer
I've used Desk and other platforms in the past and none of them are as interactive or user friendly as Kustomer.

User Testimonials
Customer.ioKustomer
Likelihood to Recommend
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.

It works really well for you to ask a teammate to review a case/email/message and provide some input since you can all review the same conversations and client accounts. They can also cover your inbox using your email handle in case you are out of the office suing some well deserved PTO.

Pros
  • Ease of use, a good tool for non programmers, or not so tech savvy people.
  • Great support, willing to help a lot, by chat, calls, or screen sharing.
  • Fast updates, it's a newer tool, but they are coming with fixes and updates fast.

  • All customer data (past orders, communication with customer service, rewards account data) is in one place. This helps agents avoid confusion and reduces the number of tabs they need to open.
  • The Knowledge Base (or K Base) is very helpful. Any time we roll out a new policy or have a limited-time promotion, we can add all the relevant information and worksheets there for the convenience of the agents. That way they can stay in a chat while looking up the answer to a question.
  • We can seamlessly move from chat into email if the customer leaves or the queue times are too long. All the interactions will stay on the customer profile page, so they are kept up to date.

Cons
  • 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.)

  • For our team, the feature that defaults all notes to begin in "done" status is difficult. Throughout each day we need to have notes open and assigned back and forth to different teams, and we have to remember to manually "open" each note. There is too much room for human error with this setting, and it is easy for important notes to be missed if a user forgets to open the note.
  • Similarly, it can be hard to remember to assign emails/notes to a particular team in addition to a user. We almost exclusively work out of team inboxes, and if someone on Care writes an email to a customer, the email will automatically be "done" when it is created, and it will be assigned to the user who wrote it, but not also to the user's team. There are instances where an email needs to be snoozed for several days/hours with further action needed, and unless the user remembers to assign the email to their team it may "awake" from the snooze and not be visible to anyone except the user who created it. Similarly to my first comment, this leaves a lot of room for human error and is not very intuitive.
  • Personally, I do not love that all tickets/emails/notes are jumbled together in the same inbox. While this gives visibility to everything on the "to do" list at the same time, it can be visually overwhelming. We have created unique folders for certain types of projects or categories of work, but have experienced tech glitches or just the awkwardness of another step to manually read the note, determine what type of category it is, and then manually assign it to another folder. Would love to have things auto-sort and take out this manual lift.
  • I love the idea of the autopilot setting, but we have not been able to use this for our work because it sorts items based on time, and not based on priority. In our line of work, we may have an urgent situation arise that needs attention before an email that was sent in 60 minutes ago. The autopilot feature would push the email to my associates sooner than it would the urgent situation from 5 minutes ago. Due to this, we manually monitor inboxes and assign work to ourselves and others.

Usability
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.

There is a learning curve, but it is more than worth it, especially to have a dedicated resource pointed at Kustomer and any other software it interacts with. The basic implementation is useful, and powerful - certainly a MASSIVE upgrade over taking care of your customers in an email inbox or shuffling between multiple windows and applications! It is also set up really well to grow and reconfigure with your business. I'm a big fan.

It’s a great tool that has helped our company and overall customer service. I believe if we were able to edit certain setting for our specific company that would be hopeful. We have been told before that certain desires of ours would make a change throughout all of Kustomer. Which is not something we would want, we would just want that to change for our business.

We used Autopilot in the past. It worked well but the integration wasn't very good, considering they only used cookies. We have a very complex system right now to be able to track every customer, and it was expensive but worth it. Autopilot worked very well when we were starting, but then it didn't track purchases, it wasn't easy to change a customer attribute, and so on (this was a few years ago, probably they have improved a lot). It was more visual and better to create huge workflows. . Mailchimp was the first program we used. It's very basic but good at what it does: sending a newsletter to your small database. It has integrated very well with other services and we haven't used in a lot of time, but certainly was grown a lot so it must be doing things fine. I also tried Active Campaign but it was almost the same as Autopilot.

I find it baffling how little data can be stored or associated with a customer in many other systems, and how difficult that can be to set up. It is fine if you already have a robust CDP that you can hook up and use to power your CRM, but it is rare that an organization has the resources or the customer-focus to rally behind setting up their customer service/experience team up for success. With a platform like Kustomer, you can actually evolve the relationship over time, or use the past experiences (number of contacts, purchases, previous issues, etc.) to power your next steps with a customer, making for a much more nuanced relationship with a human, not just a ticket.

  • Helped increase our new user engagement with our cloud-based software
  • Helped our sales team identify clients who had dropped off and stopped interacting with our software
  • Helped our sales and customer service team track which clients were completing their full registration process
  • Helped our marketing, sales, and customer service team identify key features and messaging with A/B testing for different campaigns

  • We’re getting so much positive feedback — which is not something you traditionally associate with a customer care team — because we’re making it effortless for customers to deliver both positive and negative feedback, and we can now resolve the bad feedback really really quickly.
  • Primarily from our increased efficiency with Kustomer, we’ve seen a significant reduction of $3 to $4 for every cost per contact.
