Dear Madam Mayor
The correct way to address a mayor in writing would be: "Dear Mayor Slay."
In writing, as 'Lord Mayor', perhaps surprisingly. The title Lady Mayoress is reserved only for the wife of a Lord Mayor. You should address a female Lord Mayor as "Madam Mayor" in conversation. It is considered impolite, certainly in public speaking, to address her just as 'mrs. Smith'.In writing an envelope, you use "Mrs. J.B. Smith, Lord Mayor of Portsmouth".
Whether male or female it would be: Mayor Jane Doe or Mayor Doe (as example.)

You address the person as Mr. or Madam Mayor or You Honor.
The best way to address the mayor is to call him mayor with his last name. This will demonstrate that you are professional and you know what to call him or her.
Depending on your familiarity, "Mr. Mayor," "Mayor Smith," or Joe.
