How do you address and envelope to a female pastor and her husband?

When addressing an envelope to a female pastor and her husband, you would typically write her name first, followed by her title. For example: "Rev. Jane Smith and Mr. John Smith." If you prefer a more formal approach, you can use "The Reverend Jane Smith and Mr. John Smith." Be sure to include their full names and any relevant honorifics, and place their names centered on the envelope.
