Hi {{first_name}},
I wanted to reach out personally ahead of [[customer company]]'s renewal on [[date]]. [[Account manager or CSM name]] has been trying to connect and I understand you've been difficult to reach.
I'd like to make sure the renewal conversation happens on your terms. Is the timing not right, or is there something about the plan or the product we should address before moving forward?
A quick reply pointing me in the right direction would help.
