Easy to use and awesome support

Double Opt-In for Download (DOIFD) was perfect for an easy-to-use plug-in for my client to capture leads for free downloads without the hassle of adjusting for 0.00 or pricing. The double opt-in makes it easy to build a good list for future emails, since the premium version will automatically add the leads to your mailing lists at ESPs like MailChimp. When I ran into a problem with a new update, customer support was awesome and the issue resolved within hours.
