### Comment:
I've heard this. I've also heard that it's easier to avoid spam filters (if you're blasting out emails) if you purposely misspell or use poor grammar. Not sure if that's true or not, but interesting nonetheless.

### REPLY:
Nah, most ESPs use other metrics like sender/recipient relationship markers, quality of markup code, pre-header text, IP address, etc.  
  
 I’ve heard this too, but I think poor spelling and grammar is probably due to English second language.
