Text Messaging Numbers

Text messaging at scale can be a difficult endeavor. We have struggled through the years to strike the right balance of offering an affordable service and offering a top tier text messaging experience, sometimes it works other times not so much.

With the rise of spammers, phishers and scammers, text messaging has gotten more difficult. The way systems like Resgrid work, sending a blast of messages when a Call is created in our system, looks a lot like spammers sending messages, which means our numbers can be blocked or marked as spammers when we try sending messages. Because of this we implemented regional numbers pools to help mitigate a number being temporarily blocked by a carrier.
