Weather Alert Delivery
Our system uses SMTP to send weather alerts that subscribers opt-in to receive and most often uses SMS to send alerts sent manually by administrators.
Simple Mail Transfer Protocol (SMTP) is an Internet standard for electronic mail (e-mail) transmission across IP networks. This is used for the email to SMS solution where a text message can be sent using an email client and converted into a text message by the phone provider/ carrier. Most cell phones are able to receive text messages in this format. In essence, the phone receives an email, and in fact, a message delivered in this fashion is sent to an address like "12125551234@mycarrier.com."
Short Message Service (SMS) is a means of sending short text messages to and from mobile phones. This is how most text messages are sent from phone to phone. Unlike email, SMS messages are sent to phone numbers, not addresses. They are routed through a gateway, which connects directly to the carrier's network. In order to receive SMS messages from Konexus, the recipient must first give permission by text and agree to the terms.
Why am I not receiving weather alerts?
Some cell phone providers are notorious for not delivering SMTP messages, especially when they are sent in bulk to their users, with Verizon being one of the most commonly complained about.
If you are not receiving certain weather alerts and you know of someone nearby that did receive weather alerts you think you should have received, this can be really frustrating. Chances are you have different cell phone providers. Sometimes you can opt-in with your cell phone provider to receive SMTP messages from the web, web domains, and emails. We recommend reaching out to your cell phone provider if you have issues receiving weather alerts.
