mail to comast being rate limited again

Once again I am rate limited in being able to email Comcast customers. SMTP headers review.

This was previously handled under case [Edited: "Personal Information"].

I run my own domain, and that domain sends approximately 8 emails a month to Comcast users.

@nm1233 Oh, no. Sorry for the trouble with the email. We're happy to help. Please send us a Direct Message with your full name, business name, and complete service address. 

 

To send a "Direct Message" / "Private chat message" message to "Comcast Business":

  • Click "Sign In" if necessary
  • Click the "Direct Messaging" icon
  • Click the "New message" (pencil and paper) icon
  • The "To:" line prompts you to "Type the name of a person". Instead, type "Comcast Business" there
  • - As you are typing a drop-down list appears. Select "Comcast Business" from that list
  • - An "Comcast Business" graphic replaces the "To:" line
  • Type your message in the text area near the bottom of the window
  • Press Enter to send it"
