FeedBlitz users (bloggers, email marketers, new media companies) can now specify a custom URL to send subscribers to at the end of the dual opt-in process. If used, it replaces the current FeedBlitz default landing page.
You can therefore redirect subscribers activating their subscriptions to a thank you page, your site, your current offer, whatever! And of course you can change that over time to see what works best for you.
Set a custom activation landing page at Newsletters – Settings – Content Settings – The Basics.
