Partition Transactional Messages for Optimal Delivery

With Customer.io, you have a dedicated lane to create and send your transactional messages independent of your marketing messages. This ensures your product updates, nurture campaigns, and whatever else you choose to send from Customer.io will never negatively impact your deliverability reputation, speed of delivery, or inbox placement.

Do More With Fewer Resources

Keep the momentum going and only pull in development resources when you really need them. Our platform empowers marketers to create, send, and easily modify transactional emails and push notifications on their own. No, seriously, you don’t have to rely on developers to make changes in the code anymore.

  • Forgot a variable like customer.first_name? Add it yourself.

  • Need to change a layout? Without delay, edit and save.

  • Notice you’re using the wrong snippet? Easily replace it.

Consistent Branding Everywhere

You’ve already done the hard work. Take advantage of your existing layouts, styles, and content assets in Customer.io and apply them to your transactional messages. Plus, you can leverage your customer data by personalizing your messages using liquid or pass additional variables in your API call.

Queue messages as drafts while you fine-tune content

Just like any other automated message in Customer.io, when you set messages to Queue Draft, we generate a draft rather than sending that message automatically. You can spend as much time as you need to make sure your message is looking just the way you want.

Conceal sensitive content for your security and compliance

Conceal sensitive content in your messages for SOC 2 , HIPAA, and GDPR compliance. A simple toggle will prevent Customer.io from retaining sensitive data, like password reset tokens.
