Sometimes talking on the phone can be stressful, because an immediate answer is required. No one likes awkward silences, right?
Psychic readings done over email can give the psychic time to get attuned to your question and connect it to the spiritual realm for answers. Taking more time to ponder your question or situation could result in a better, more accurate psychic reading, then delivered to you via email. Much like a phone or in-person meeting, you would have a record of the reading to look back on should you need a concrete reminder of your reading.
Email readings are beneficial if you are busy in other aspects of your life, and don’t have time to commit to a phone call or an in-person meeting. Additionally, I tend to get a bit socially anxious when meeting with new people, and sharing a personal question or asking for psychic advice can be intimidating to me. Through email, I can ask my questions and then sit back and let the universe handle things from there.
