Which one works better in the casr of Opt-ins?

[mediadrug]

We are launching a email list building campaign in a odd and new niche. So, we have decided to use opt-ins (its tested and work great). Now here is my query should I use single opt-ins or double opt-ins on the landing page?

No one can tell that to you. Because in each case it works differently. You should split test it first using two landing page at once or use it on a single landing page by altering the time.

In a single page one opt-in is best as far as I know. People always gets spooked if you put more than one.

Go for single opt-ins they are more realistic.
