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.

Inbound messaging it is top notch, it does it well and couldn't imagine anyone's program doing it better. Like I said before been using ZenDesk for over 7 years and absolutely love it. We use the talk feature with the phone very limited so Zen works fine for us, but if I was running an inbound or outbound call center I don't believe Zen has all the functions I would want as a manager. For limited phone use and mostly email, text, and even web chat, ZenDesk works great. Having the iOS App is so great and flexibility with notifications allows my team to be "on call" anytime without unnecessary interruptions

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
  • 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.

  • I think the Graphical User Interface could use a facelift. It not the most aesthetically pleasing platform in my experience.
  • Particular things like where the default is when you click on each and every dropdown menu.
  • The macro integration could be a little more simplified.

Zendesk is super easy to use and navigate. I really enjoy the sleek layout, the ability to tailor tickets, the macro option, and the quick key guide they have to make your use of time even more effective. My whole team loves working with Zendesk and rarely ever has problems.

As an agent it's very simple to use. As an admin it's also easy to use, but sometimes lacks some functionality that would be nice to have such as expanded native 2 way sync functionality for many major apps that are commonly used today like HubSpot and Salesforce. The ability to add followers to tickets to they get updates and are in the know without the customer seeing this agent cc'd is a nice touch. This ensures additional visibility and easily following the communication without having to appear as a CC to the customer, who could accidentally remove that person in a response, thus breaking the visibility

Every time I contacted them they were not only very responsive and knowledgable, but always seemed to have a positive upbeat attitude. It probably helps that we did not have significant service outages or sev 1 level issues, but even my lower severity issues were quickly answered. And the positive and upbeat attitude really made things feel comfortable.

Zendesk has tons of available material for training - videos, webinars, articles, etc. The only reason this is not a 10 is because it can be hard to figure out how to navigate to these things and find what you are looking for.

I was very satisfied. They have a free trial for 30 days and I recommend you do that and use it. It is very easy to get started with the basics and the build on over time.

The only thing technically complex was single sign-on and integration to Salesforce.com required some tweaks – otherwise setting up system was very easy

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.

If spoken honestly Intercom is a level-par with any nearest competitor, Tools like Zendesk has to catchup with them in speed. However, there is an advantage to Zendesk with its simple and easy-to-get software which falls in every mid and small-size business pocket wherein Intercom is way too expensive and needs a tech admin to customize the product. The kick-starting feature with negligible configuration made Zendesk the ideal choice of our organization + the budget fell under our expenses.

  • The positives weigh more than the negatives here, as it gives us a one-stop portal where we can tend to customer needs using one web app
  • It has also helped us identify areas of improvement based on the reporting feature
  • The value it provides outweighs any missing or lacking features that I'm sure will be available in the future
