Thanks! I was initially using eFax but their $16.99/mo fee was waaay too high for my usage, so then I tried to use HelloFax but their sign up form was busted.

Thanks! I was initially using eFax but their $16.99/mo fee was waaay too high for my usage, so then I tried to use HelloFax but their sign up form was busted. Ended up with Phaxio while searching for an API to power my own web-based fax app which never materialized after I found the email integration.
