Ask HN: How to create a single email field like on basecamp.com
I tried to implement a single email field on my saas website for free trial signups. But I got bombarded by spam. Using google invisible recaptcha make the user experience very bad. Is there are any other work around? Given the spam rate I decided to remove it for now. But I am curios about how basecamp is doing it. I have seen it on other websites as well but some of them do no post the data...
