Proper use of "Honorable"

[Unregistered]

I need to send a thank you letter to a person who has identified herseld as "Honorable Jane Smith". I don't know her specific title, i.e. judge or senator. Writing Dear Honorable Jane Smith doesn't sound right, but neither does Dear Your Honor.
Any suggestions?

You say you don't know if she is a judge or a senator.

Where is she writing from?

She is responding to a donation request sent from the non-profit I work for. We had her incorrectly listed as "Mrs." which she crossed out and wrote Honorable. This was not in letter form, but one the adress section of a flyer. I had thought she was a school board member, but apparently she is addressed as Honorable so I'm not sure of her current title/political position.

"one the adress"
should read "on the address"
sorry!

It is difficult to be sure of her position as this is used for a number of public offices, but you should address the letter and envelope to The Honorable Jane Smith, but start Dear M[r]s Smith.
