Iris has pictures of 35 journals on its website -- 36 you count the World Journal of Yoga and Natural Therapy twice -- because it "is an ambidextrous journal."
The domain name irispublishers.org is registered to New Dream Network, LLC dba DreamHost Web Hosting. The telephone number on the contact page, 914-407-6109, also is used by Lupine Publishers, which is "focused on ... Remedial missions in relation with Technical Knowledge." Virtual office supplier, Regus, could be the source of the address of the office building in San Francisco. Clearly, there is reason to wonder where Iris is actually located. The spam inviting me "to join your hands with us in this instigate" suggests that the handshake would be quite a stretch.
UPDATE: Two comments of July 13, 2018, provide more information. One from "Smut Clyde" reveals that the common telephone number for Lupine and Iris (not to mention the flowery association) is no accident. He (or she) found that
Iris Publishers LLC is a Colorado Domestic Limited-Liability Company filed on May 18, 2018 .... The company's principal address is 7865 S Grand Baker St., Aurora, CO 80016. That Aurora street address is also the home of Lupine Publisher, Crimson Publisher, "Biomedical Research Ltd", and Sudheer Kaku (the scammer who registered the corresponding domains).
