While Maitreyee thrashed Papua New Guniea's Vero Nime 3-0 in group 1, Vaishnavi went down 0-3 to Nigerian Faith Obazuaye in group 2.
Maitreyee overcame Wednesday's loss to Australian Melissa Tapper, with a 3-0 (11-2, 11-9, 11-2) win over the PNG paddler.
She will next face England's Felicity Pickard on Thursday for a place in the semi-finals.
On the other hand, Maitreyee's compatriot Vaishnavi's dreams of reaching the semi-finals are almost over after losing 0-3 to Nigerian Obazuaye.
The Indian had no reply to the Nigerian's aggressive play in all the three games that saw her winning 11-0, 11-2, 11-2.
Vaishnavi had earlier lost to Canada's Stephanie Chan on Tuesday. She will next face Australian Andrea McDonnell on Thursday.
