It looks like you have some typos in your message. If you're asking for an acronym that can ensure someone reads your message, the most appropriate would be "FYI," which stands for "For Your Information." This acronym indicates that the information provided is important or relevant for the recipient to be aware of.
If you meant to convey a sense of urgency or importance, "IMHO" (In My Humble Opinion) is less about ensuring the message is read and more about sharing an opinion respectfully.
If you need any more information or clarification, feel free to ask!
