This is an easy way to keep track of how long it takes to email someone. You can also use this tool to see who has read your emails. It's not free but is very affordable. I have heard that there are some features they're working on that will be added soon. Make sure you sign up for their newsletter because they often announce upcoming changes. The most helpful thing with SendHawk is being able to easily see what people have opened or replied to my emails. If there isn't any feedback from them, I am not sure how beneficial this really is. I would say to give it a try. There haven't been many things that I've disliked about SendHawk so far. It does have its downsides such as not having access to all the features yet. It's a great way to know who is reading your emails and when it was sent out.
