We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
If you use gmail, you can try out streak.com. It's free but you have to use the Chrome browser for it to work when you send your emails. There are paid options too like yesware and some others. Source: almost 3 years ago
I see no specific issue with sanebox.com, however it appears that they are only offering a service you can do on your own. Honestly, do you really get that much SPAM? Source: over 1 year ago
