Dear Friends,
Running a free and helpful website like ESENotes.com has always been a passion-driven mission. We aim to provide valuable resources, notes, and tools that support students, educators, and knowledge seekers across India. However, maintaining and improving this platform comes with its own financial challenges — including server costs, content creation, domain renewal, and development work.
Currently, I’m facing some personal financial difficulties, and it has become increasingly hard to keep the website up and running without external support. If you’ve found ESENotes helpful in any way or believe in the value we provide, I humbly request your help.
Even a small contribution can make a big difference. It will go directly toward keeping the website active and continuing to improve its offerings for everyone.

With gratitude,
Founder, ESENotes.com
