we have been using LeadPal for just over 1 year now and it has, without question, increased our opt-ins by a minimum 20 to 25%, and for a few reasons, I believe. One is convenience, people would rather "click" than "type". Secondly, I believe people do not feel they are relinquishing any personal information when they click onto a social icon, yet feel they're divulging personal information when they type their name and email address. And third, just the ability of enabling engagement via social logins over traditional form-filling seems to convey credibility in the minds of some "opt-ins"! (they think we are in cahoots with Facebook, Google, etc.) Overall, NO regrets signing on with LeadPal.
