Mass email

I use a free e-mail address of yahoo, and I recently noticed some limitations, which I would like to overcome. I had to send information (a newsletter) to a large group of people (1800), and used a category in the address book for this purpose. I discovered that the free yahoo e-mail allowed only a maximum of 40 e-mail adresses in the CC. window (which I must use to guarantee the anonimity of the addressed people). Furthermore, I discovered that I could send e-mails to no more than 100 or so people in an hour, and to no more than 200 or so in a day. These are of course severe limitations in view of the 1800 people I want to reach. Therefore I would like to get your advise: how can I extend these borders, so that I can address this total of 1800 people in a few days or so? If this extension requires the extension of my e-mail address, that is, paying for the services, I would like to know which package is able to do the job.

I have a ton of email addresses from my site, and I am trying to send a mass email using G-Mail. When I paste the mass list (not formatted with semicolons) GMail says they cant recognize some of the addresses (presumably because there are no semicolons in between them) How/what can I do to accomplish what I am trying to?

I have, this week, started getting between 200-300 returned emails with the “Mailer-Daemon” (or some similar spelling) “Undeliverable” message on them every single day in my inbox. I mark them as spam and all because I do not know what else to do. I have not signed up for anything new. I have not done anything at all that I have not done in the past. Now, I am suddenly getting mass emails about undeliverable mass emails that I never even sent out en masse in the first place. It is very annoying to say the least. Is there anything I can do to fix this problem other than deleting my account with Yahoo and starting fresh? I do not know why it started, but I am ready to choke the internet. Thanks in advance.
I know what the Mailer Daemon thing is, but I have, this week, started getting between 200-300 bounced/returned emails with the “Mailer-Daemon”/ “Undeliverable” message on them every single day in my inbox. I mark them as spam and all because I do not know what else to do. I have not signed up for anything new. I never forward emails. I may send 2 emails out every two or three days. I have not done anything at all that I have not done in the past. Now, I am suddenly getting mass emails about undeliverable mass emails that I never even sent out en masse in the first place.

Please E-Mail me again to let me know to pawpaw491@yahoo.com

First off, how do I legitimately buy/obtain a large number of emails if I wanted to started a nationwide business?

I signed on this morning and had lots of undeliverable returned mail, which I didn’t send out. I went to my send box and there were lots of emails sent out as me (though I wasn’t online at the time). I understand this means someone is using my email address as the reply to, but how can I have this stopped?

when I try to unsuscribe by hitting the link or sending email to the sender address…the mailer says cannot send…

Thank you for the replies. I know about deleting the 25 mails per page by selecting all, but there are 14807 currently and that would take forever. Is there anyway perhaps I can view more than 25 per page, say 100 per page, so that I can delete 100 at a time? Thank you so much for taking the time to respond x

I need to send about 5000 emails to customers at once. Can I just put all the emails in the CC:?

I’m emailing a lot of people who have responded to an ad online. I don’t have their names in my contact list. How can I easily email all of them?
