Customer.io
Talking from the perspective of a marketer at a SaaS with average. 50K email subscribers, Customer IO has been an excellent tool for us. Our requirements include sending users newsletters, marketing emails, and transactional emails, running lead-nurturing campaigns, and more. For a comprehensive use case like ours, CustomerIO is great. While it also has a learning curve, when you have such requirements, it’s worth it. I don’t think CustomerIO is the best fit if you have basic requirements like only weekly newsletter emails.

Smartlead.ai
Smartlead is well suited in many aspects. Thats why we are working on it from past 3-years or so. Running email campaigns can be a challenge because other bulk email providers do support sending email but the accuracy of landing in the inbox no one guarantee. I have used it and based on the experience I am using Smartlead. I have used mailshake, apollo, instantly, salesloft etc. none has given such results compared to Smartlead. When it comes to less appropriate: Smartlead is for sending bulk email, one cannot maintain records on the same. I have to delete the campaigns because it will pile up in the home screen once completed. Also Auto-tagging feature should be there based on the response received from prospect. If we use it as CRM, there are chances it can fail. Since it provides unanimous master inbox- I can not respond to my prospect from the dashboard because other colleagues might see my response. This is a security concern.

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.

Usability
Customer.io
Super intuitive and easy interface to start off with. There are not a lot of guides and the documentation is helpful but not super extensive, but even if you're a little technical, you can easily figure most of the things out by yourself. Everything is super easy to start with and the platform does not overwhelm you with a lot of options, or data.

It's a good tool and you can figure out your way around it, but overall visibility from a bird's eye view could be better. Oftentimes you have to open up multiple tabs to see different client views

Customer.io
My experience with their support team has always been great. Very quick to respond, have an online chat, and are very helpful. They helped me resolve any issues I've had every time in a professional and knowledgeable manner. We've now switched to another tool, and I can't even compare the service level we get there to customer.io

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.

I have used all above platform in my career. Instantly is the nearest one which can compete. relying on Apollo was my biggest mistake over the years in my previous org. Apollo does not give clear picture whether the email is bounced what the health score of my domain. I kept on using the same mailbox and my emails kept on landing in spam. I couldn't understand the reason behind my poor performance until I used Smartlead. All other tools gives fake health score, no AI suggestion on setting up campaigns. Here Smartlead outstand with other tools.

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.
