Thanks Danielle! Twilio plays a big role here at PagerDuty. You guys have been great. More importantly, on the few occasions where's there's been service hiccups, we've never had problems getting hold of someone at Twilio. Can't say the same about other providers we've tried.
You're welcome, and I'm happy to hear you've been satisfied with Twilio's service - we're really passionate about doing it right and we'll always be here to help
Btw, I've left you a "gift" in your Twilio account... whenever you happen to check your account balance :)
