Email to text - vtext.com blacklisting ip

Unfortunately I am not in the same boat here in Milwaukee WI all messages to vtext.com personal and business on greater that four subnets that we own are being delivered. I would suspect what you are seeing may be a local problem to be resolved soon.

Same boat...  We are sending messages to PHONENUMBER at vtext.com and getting
bouncebacks or lost items.  I assume its because some limits are now being put
into place.  We are a Verizon subscriber so I am paying, it is not a free
service.  But .... I am totally up for paid services if you can recommend some
that will reliably get us texts to our verizon phones.
