Email tab opens with Inbox

Email tab opens with Inbox

Hi Zoho team,

I'm facing a challenge. Everytime i open my zoho mail in my web browser an email from my inbox is also always open. Its the same email thats open everytime. 
Basically everytime i login to my email along with the inbox showing the same email tab opens. Even if i close the tab, the next time i login to my email it opens again.

Kindly help me solve the problem.

Thank You.

Regards,

Nivin
