This may happen to you: A few times each month I get an email delivered to my junk/spam folder from an address such as email@example.com. If I happen to recognize the 10-digit phone number before the “@” symbol I can recognize who it’s from, and respond accordingly. But often times it goes unnoticed or unopened.
When sending messages from a smartphone you typically have 2 options – a “Messages” app and an “Email” app.
The Messages app is meant for sending short messages – usually 160 characters or less – to the recipient’s phone number. The message can be accompanied by one or more photos. If you incorrectly send a message to an email address, it goes through your wireless carrier’s SMS-to-email gateway which converts the message and appears to the recipient as an email coming from “your-mobile-number”@”your-carriers-gateway” – as described in the beginning paragraph of this article. Messages typically cannot be read on a computer – they are meant for mobile-to-mobile communications.
The Email app is meant for sending an email to the recipient’s email address. Emails can contain lots of text, photos, short videos or other attachments, and can be recognized by the recipient in their as originating from your display name and/or email address.
The next time you originate a message or email from your mobile device, make sure you are addressing the recipient in the correct app and correct format – using their 10-digit phone number or email address appropriately.
