Hyland's Naturals review for Notify Me! Back in Stock Alert

This does exactly as advertised, with great tools for customizing appearance on page. Took under a half an hour to implement and had customers requesting notifications within a few hours. Hengam's Customer service was excellent as well. I had a technical conflict with DKIM authorization when sending from a custom email, and they immediately addressed the problem and began working on an alternate solution for me. Great all around.
