So what

Overall, results for the latest quarter were strong. Revenue growth remained stable with previous quarters, up 65% year over year. The company ended the quarter with over 250,000 active customer accounts, compared to 208,000 in the same quarter a year ago. Customers also continue to spend more after signing up for Twilio's leading communication products, including marketing tools for messaging, video, email, and other solutions, with the dollar-based net expansion rate remaining at 131%. 

One thing that stood out was the introduction of Twilio Engage on Oct. 20, which is another step toward investing further in its customer engagement platform strategy. Twilio Engage can help companies build personalized marketing campaigns and gain a greater share of wallet with customers. The rollout of Twilio Engage follows the year-ago Segment acquisition for $3.2 billion, which combined Segment's data insights with Twilio's cloud communications platform.

Now what

For now, market participants are more concerned about decelerating growth expected in the fourth quarter. Management forecasts next quarter's revenue to be up 39% to 40% year over year, which is below the 60%-plus level investors have gotten used to lately. 

With many stocks trading at high valuations, market participants are on pins and needles right now. Any sign of weakness is likely going to cause a highly valued growth stock to get slammed in this market environment, and that seems to be what happened with Twilio.

Investors will have to adjust expectations, so the shares could remain volatile, but management expects to maintain at least 30%-plus growth over the next three years.
