Second and third places respectively went to India with 7.5% and Russia with 5.4%.
May saw major shifts involving China (3.6%) and Brazil (3.7%) – these countries have started to slowly win back their positions. They are not in the Top 5 yet, but could be soon. The 4th and the 5th places in the Top 5 are occupied by Vietnam and the Republic of Korea with 4.8% and 4.1% respectively. Noticeable changes happened to spam flows coming from Germany and Italy, they dropped out of the Top 10 having distributed 2% less spam each compared with the previous month.
