Were currently having this problem with our current email marketing. the thing is we need to send around 100,000 email in a day, but were having this bounce and opting problems from the server / host / provider, can you help me lookout for a credible 3rd party company to help us send 100,000 email a day.
I had used bulk email service of about 100000 emails one time for one of my client.
Try this:
<!-- m --><a class="postlink" href="http://www.sendbulkemailserver.com/">http://www.sendbulkemailserver.com/</a><!-- m -->
<!-- m --><a class="postlink" href="http://www.sendblaster.com/en">http://www.sendblaster.com/en</a><!-- m -->
This two are really good.
