Meghan Markle praised the work of women campaigning for safer gun laws — and sent them some "delicious and appreciated" treats to keep them fueled.

Shannon Watts of Moms Demand Action revealed on Wednesday that the organization had received a personal note from the Duchess of Sussex.

"@MomsDemand volunteers and staff have been working around the clock for weeks, so it was moving to receive such a supportive note - and snacks! - from the Duchess of Sussex today," Watts shared on Twitter along with a photo of the note.

Watts later followed up with another tweet: "Lots of questions about the snacks! Donuts, bagels w/the works, coffee, cookies, etc… Delicious and appreciated."

Meghan's note was on stationery featuring her royal monogram, a simple cursive "M" topped by a crown.

"Good afternoon ladies!" the mom of two — son Archie, 3, and daughter Lilibet, 1 — wrote. "To each of you and your fearless leader, Shannon, a huge thank you for the work you are doing to keep our kids, families, and communities safe."

She continued, "Please know that while you may feel exhausted by your endless hours of dedication to this cause, I hope you feel energized in knowing that the work you're doing is vital and so deeply appreciated. As a mom, as a friend, thank you so much!"

Meghan, 40, signed the letter with her first name in her recognizable penmanship (she once worked as a professional calligrapher!), above a typed "Meghan, The Duchess of Sussex."

Moms Demand Action describes itself as a "grassroots movement of Americans fighting for public safety measures that can protect people from gun violence. We pass stronger gun laws and work to close the loopholes that jeopardize the safety of our families."
