After my research on above studies I tried to find out the top days for email open rates:

Tuesday – This is one of the top days where email open rate is high by reading the above studies.

Thursday – This day should be your second priority, and should work well if you are sending other mail in a week.

Wednesday – No study showed that this is the best day, but yes this could be your third priority

Note: Some of the studies also shown that the Email Open Rate & Click Through Rate is higher in weekends (Saturday & Sunday) but total number of emails open are quite lower on these days.
