It might be a good idea to say on the landing page whether it's intended to work outside of the US.. You give a stat on the landing page of how many spam calls there are in the US, this hints you're mainly US focused?
@smithjamey The unfortunate thing is by mid-2018 all the promotion here will be over, so I will forget about Kalleo unless I'm willing to have six months of emails that are relevant only to Americans.
@SHalloranNCL Thanks Shane for saving me some time, it's always assumed only Americans will read the promotion. For U.S service-based startups, I now often ask if it's U.S only before even looking at the website.
