This is a development project and not intended for production. Do not use it for your email survey campaigns.
Emailify is a solution for handling your email survey campaigns. You simply buy credits (1 credit = 1 campaign sent) and create your survey!
You must have a Google account to log in, as it only supports OAuth for Google. Then you buy some credits! To "buy" credits, use one of Stripe's test cards. This will not actually charge money, of course. Then click the red button on the bottom right corner of the screen and get sending!
