Re: Email to text - vtext.com blacklisting ip

[Dovid Bender <dovid () telecurve com>]

We use Zang.io and are very happy. Be careful when using long codes (10
digit numbers) as if you send too many messages out in a day (500+) the
larger carriers such as Verizon will start blocking you. As Jeff mentioned
if your monitoring tool is onsite and the internet goes down then it's
worthless. In our case it's in another DC so if everything goes down we
still get alerts. You can also try twilio and telnyx.
