Hey Nick, Daniel with MailLift here.
TL;DR MailLift is international and servicing most countries.
If you have a mailling address in the US and would like to send international letters, there is an additional $0.66 charge for international stamps.
If you have a mailling address outside of the US or Canada and you want to the letters to be postmarked from that location, you can request a quote by going to our intergrations page, clicking "Get Started" and leaving a comment in the "Comments" section. Please include the the number of letters per batch and the frequency you expect. (i.e., I'd like a quote for 50 letters per day sent internationally from Paris, France and a seperate quote for 250 letters sent per week from Paris, France.)
