Starting in June 2019, we have noticed a 50% increase in links that were clicked via a text version of our emails vs. HTML. We know this because we use a different URL in the HTML version. We have seen our opens drop overall as well and assume that we are delivering more text emails vs HTML emails. Has anyone noticed this as a recent trend and are there any factors in our emails that could be causing an email client to choose the text vs. HTML version. Our email campaigns are the same year-after-year for each month, so we have a good handle on what to expect in regards to opens and clicks. But we aren't sure if we are contributing to the increase in text email deliveries or are there other trends out there that we aren't in control of?
