Zendio Email Tracking v Microsoft Email Read Receipts

2/5/2013 5:00:00 AM

A common question we get is how Zendio email tracking differs from an email read receipt in Microsoft Outlook. We first addressed this question about a year ago in this blog post, but thought it might be time for a refresher. As we will explain, Zendio offers a far more robust and reliable service when it comes to tracking emails.

Q: Does Zendio work with mail clients other than Outlook?
A: Zendio is an add-in for MS Outlook. However, if you use an email system that allows you POP access Like Gmail you can easily use MS Outlook to connect to that mail account. Once that email account is set-up with MS Outlook you can use Zendio to track those emails also. For more information on how to set up POP accounts in MS Outlook please see this link.
