I am the founder of SendOwl and this is not a project by us. It's clearly ripped off our brand though. Will be getting in touch with them to discuss the matter immediately.
This is very confusing - you might want to think about another name or at least changing your design.
The name, logo and theme/color-scheme are all very similar to sendowl. So much so that I assumed that this was another project by the sendowl team until I saw this comment.
