Dear Aditya, Communication such as this is often filled with gratitude and future promises. I request you to think beyond that. You have an option to introduce yourself with what you wish to do in the organization and share what you have done so far, beyond your resume.
Reflect on Your Capabilities
However, that's time-tested, yet to an extent, unreal. Please make a note of what you want your new team to know. This is beyond every admiration and adulation that you have received so far. Take a hard look at your capabilities. Suppose you have excelled in managing Payroll. This has already been mentioned in your resume. Yet, what nobody knows is the effort and challenges that required you to become an expert and any failure that marked the landmark success of your career. Generally, most of us are apprehensive about sharing a failure. Nevertheless, it will make you human and honest to your team.
Embrace Transparency
Eventually, they would all get to know you. Hence, it's pointless to hide your fault. Presenting your capabilities and limitations with maturity and grace will earn you respect.
The rest is your choice. Wish you all the best!
