Four emails out of 1600 page views means that only 0.25% of visitors

This doesn't change the advice above, but that's not accurate. You're looking at page views, not "unique" visitors (as unique as can be anyway.)

With 4 calls - If you had 16 people visit, and each looked at 100 pages, then you have a 25% conversion. If you had 1600 people visit and each looked at one page, then it's .25%

Where that might make a difference is as you watch the number of visitors vs the number of page views. Are people landing, hitting one or two pages, then leaving, or are they looking through 20 pages? The second type of visitor is the one that you should have a better chance of converting, as it may be that they are committed to searching for something they can't find. If you can help them find it through your stat information, you may actually lower your page views but increase your conversions.
