Not a Good Fit Resignation

Dear [Manager's Name],

After careful consideration, I have decided to resign from my position as [Job Title] at [Company Name], effective [Date].

While I respect the team and the work being done here, I have come to realize that this role is not the right fit for my skills and career direction. I believe it is best for both of us that I move on.

I will ensure a smooth handover during my notice period.

Thank you for the opportunity.

Regards,
[Your Name]
