Kate Middleton and Prince William used to regularly respond to the letters that they receive from royal fans. But it was recently announced that they will limit their correspondences with their supporters.

The Duke and Duchess of Cambridge will only release thank you notes to commemorate the most important occasions in their lives such as birthdays and anniversaries. In the past, they responded even to the congratulatory messages over polo match wins and the like.

But just weeks after the royal couple put their foot down on their decision, Princess Eugenie seemingly defied their decision. The royal and her husband, Jack Brooksbank, sent out thank you cards to those who greeted them on their first wedding anniversary on Oct. 12.

The royal couple’s thank you notes were written by Princess Eugenie’s assistant private secretary, Charlotte Fenn, using an elegant font. But Fenn’s signature is handwritten.

“Princess Eugenie of York and Mr. Jack Brooksbank have asked me to thank you for sending them your congratulations on their first Wedding Anniversary. They are very grateful to you for thinking of them and send you their best wishes. Yours Sincerely, Charlotte Fenn,” the thank you note read.

Meanwhile, Prince William and Middleton’s staff responded to a fan’s inquiry last month. The royal fan didn’t receive a thank you note from the royal couple even though she greeted them on their wedding anniversary.

“With regard to your inquiry about their wedding anniversary, The Duke and Duchess of Cambridge greatly appreciate all the messages that are sent in celebration of special events. However, with limited resources available to handle the growing volume of cards that they receive, Their Royal Highnesses will now focus on responding to a select number of these occasions such as Christmas, birthdays and significant anniversaries,” the staff explained.

Alongside the explanation, the royal fan also received a photo of the Duke and Duchess of Cambridge enclosed in the envelope.
