I have an opt-in list from my eBay stores of 300,000 email addresses.
I want to send, just for one time, a newsletter to all of them.
I dont want to use third party services. I want to send the emails from my home pc.
I’ve got some bulk emailer software, but I am afraid I may get blacklisted.
use a third party service.I use them all the time for these situations and they dont blacklist me.
If you send them through your ISP’s SMTP server, they will block you for suspicious activity. If you say you are using your internet connection for business, they will try to sell you business internet at business prices.
You could download and run your own SMTP server but your ISP may block the port you need to use, so it may not work.
You may have to pay a company to do it for you.
