Newsletters and email lists are one of the best performing marketing methods online. It’s almost strange that email marketing works that well in every market imaginable.
The simple fact is that people still use email as their main mean of communication online. Even despite the amount of spam that’s circulating around.
In our opinion, placing an email newsletter signup form on a coming soon page is one of the best things you can do. Period.
If you’ve managed to arouse enough interest in the product/site then at least some percentage of your visitors should be interested in getting timely updates about it.
Also, you can then use the list to announce the launch the minute it happens. This will bring you an additional stream of visitors right from the get-go.
