Manager in Marketing (11-50 employees employees)

Use Cases and Deployment Scope

We use Customer.io to send marketing emails and newsletters to our customers and clients. We have a variety of audiences and products with very different needs (some are medical clients, others are healthcare professionals), and we send most of our communications via Customer.io. We do not use it for appointment reminders, as those are integrated in our scheduler.

Pros

  • Audience Segmentation
  • Security and User Control
  • Integrated Campaigns (email, SMS, etc.)
  • Metrics and Analytics

Cons

  • Not native SMS features (integrates with Twilio)
  • Email designer (low/no code version)
  • Send criteria clarity

Return on Investment

  • Increased schedule rates for appointments
  • Increased consistent customer interaction (monthly newsletter)
  • Helps us segment our audience better so we can target based on need instead of a lot of generic emails to broad audiences

Use Cases and Deployment Scope

Customer.io tool is amazing for email marketing. It's very comprehensive, lets you go into a lot of detail, and is also user-friendly. I have used it to handle email marketing flows and newsletters for various clients. Since it's so complex, there's a bit of a learning curve. But after that, it's so easy to create flows that trigger at different times of the day/week or whenever a user performs a certain action. The editor is also much easier to use than some other email marketing tools I've tried.

Pros

  • Lets you create email flows without knowing code.
  • Easy to create nice looking newsletters.
  • Can easily segment users as many ways as you want.
  • Great customer support and documentation.

Cons

  • Price is quite expensive for Premium or once you get into high volumes of contacts.
  • Depending on how you'll use it, it may require some help from developers to set up.
  • Despite the support being great, you have to email them, there's not chat feature.

Most Important Features

  • Workflow creation.
  • Segments.
  • Content editor.

Return on Investment

  • Boosted open rate and CTR thanks to easy to use AB testing feature.
  • Helped generate sales for B2C customers through promotional newsletters.
  • Reduced time spent on creating emails/newsletters due to how well their editor works.
