I like how you can customize your letter, it's easy for people who don't have access or time in their day job as well! Sometimes when they are sending out multiple emails at once sometimes one of them will not go through but other than that everything has been great so far!! They really need an app though if someone wants something similar where there aren;t too many options around here (in my area anyways).
It would be nice just because some companies might want different things depending upon what state/city we're talking about etc., maybe then everyone could use all three? Maybe even make another option besides emailing directly which doesn’t always work either since most employees now days also get messages via text message instead of phone calls unless its urgent stuff haha.
