We're an e-commerce company looking for help with fixing our deliverability stats.
We just brought up ReturnPath and applied for certification, which should improve the percentage of our sends that end up in people's inboxes (vs. spam folders, or getting blocked).
Specifically, we're seeing the most blocks from Gmail - without a good understanding or visibility into their algorithm, we're not sure how to fix it.
Basically, we're needing guidance on best practices moving forward, and creating a system that ensures that we're removing disengaged users, etc.
We work with ExactTarget, so ideally you're familiar with the platform.
