This may be a stupid question, but I can't find an answer...
I'm sending an attachment to multiple people using python:
sendMail( ['person1@mail.com', 'person2@mail.com'],
"Your Mail","",
["letter.pdf"]
)
I'll be using Gmail and SMTP to send the mail. There will be anywhere from 50 to 5,000 recipients. The files should be about 2 MB.
My question - Will the attachment be resent to Gmail for every recipient or just once? I'm trying to figure out what my Bandwidth out will look like - 2 MB or (2MB *500 people) 1000 MB?
You upload the file once. How they distribute that file to all of the recipients, I'm not sure. But that's something they handle for you so you don't need to worry about it. Hope this helps.
