Hi this.to.firstName,

I hope this note finds you well!

I'm currently applying for a role.type position at company.name, and I believe that you would be the perfect contact to request a reference from.

You are someone who has good knowledge of my skills and abilities, and as such, I would like to include your name in my list of references.

Kindly let me know if you are comfortable with the request and if there is any information you require from my end. If desired, I would be happy to highlight some of the accomplishments from company.name I'm most proud of, or fill you in on the details of the role I'm applying for.

Thank you so much for your consideration.

Sincerely,
this.firstName
