Quick answer
Chat Russian clips endings and drops stress entirely. спс = спаси́бо, норм = норма́льно, щас = сейча́с.

Why it is written without stress or capitals
Nobody types stress marks, and lowercase is the default in messengers. Reading chat Russian is therefore its own skill — you are suddenly without the two crutches textbooks give you.
What not to copy
Clipped forms are fine with friends and wrong in an email to a landlord or an official. Keep спаси́бо, пожа́луйста, здра́вствуйте for anything written to someone you do not know. Чё in particular sounds rude in the wrong setting.
Typical mistakes
Writing спс in a formal email
Спаси́бо!
Abbreviations belong to private chat.
Reading щас as a typo
щас = сейча́с
It is a deliberate spoken-form spelling.
