Mario and Luigi
At the beginning of the game, Princess Peach sends Mario and Luigi a letter inviting them to the party. The letter is carried by Parakarry.

I'm throwing a party at my castle today! Mario and Luigi, I would be honored if you both could attend. Many guests from distant towns are hoping to meet you. There will be tasty sweets and all kinds of entertainment! I hope to see you here soon!

Sincerely, Peach

At the end of the game, Princess Peach sends them another invitation letter, but its content is not revealed by the game.

Little T.

 * The first letter Mario receives is from Little T., a young Toad who trains at the Toad Town Dojo.
 * The letter is received after Kooper joins the party.

Dear Mario, How do you do? I'm Little T. I'm just a little Toad. I live in Toad Town. I've been training at the Dojo so I can save Princess Peach! I'll write to you again later. Bye!

Vanna T.

 * The second letter Mario receives is from Vanna T., Chuck Quizmo's assistant. It is the second letter in the coding of Paper Mario, but Mario doesn't receive this letter if he hasn't participated in Chuck Quizmo's quiz show.
 * It is received after Mario correctly answers the first Chuck Quizmo Quiz.

Hello, Mario. I'm Vanna T., Chuck Quizmo's lovely assistant. Thanks for participating in our quiz show. Our ratings are through the roof! Are those Star Pieces helping you? Please keep coming back until you answer the last question! I'll cheer you on!

Vanna. T

Koopa Bros.

Hey! Watch your back when you walk at night!

You'd better sleep with one eye open, pal!

Koopa Troopas

 * The fourth letter Mario obtains is from the Koopa Troopas living in Koopa Village.

Dear, Mario, Thank you so much for taking care of our Fuzzy problem. We, the Koopa Troopas in the village, really appreciate what you've done for us. We must apologize for not rewarding you with anything. We are but simple Koopas... Please drop by the village whenever you like. Anytime. It'd be our honor. Best of luck from all of us! Sincerely, Koopa Troopas at Koopa Village

Moustafa

 * The fifth letter Mario obtains is from Moustafa.

Hey, wanderer! I have heard many stories about your deeds. People speak very well of you. It comforts me to know that Bowser's creatures no longer loot the ancient ruins. Unfortunately, some relics are missing. This is a shame. I've heard that a Koopa was wandering around the ruins... That sounds very suspicious. You should be careful if you meet any suspicious types. Anyway, I must go! I look forward to hearing great tales of your adventures. Please drop by the village whenever you like. Anytime. It'd be our honor.
 * Moustafa

Kolorado

 * The sixth letter Mario obtains is from Kolorado.

How are you, dear boy? I've just finished my exhausting research of the ruins found by my unwavering efforts. Sadly, I did not find any treasures as valuable as I had hoped. I will press on, though, old chap! There are treasures hidden all over the world! I hear them calling my famous name, asking me to dig them up!

Goombaria

 * The seventh letter Mario obtains is from Goombario's little sister, Goombaria.

To Mario, Are you and Goombario doing OK? I'm fine. Oh! This is Goombaria, by the way. Are you having an exciting adventure? Is Goombario being a hero? Or is he just goofing off? You know... I sometimes go shopping in Toad Town with Mom. Maybe we'll see you there. I'd really like to hear some of your exciting stories. I can't wait! Really! You can beat up Bowser--I know it!♡
 * Goombaria

Tayce T.

 * The eighth letter Mario obtains is from the Toad Town cook, Tayce T.

Hi there, Mario. Are you eating regularly? You know, breakfast is the most important meal of the day! The Cookbook you gave me really comes in handy.♡ I already knew a lot about recipies, but with this book, I can cook a world of new dishes! I want to tell you about the latest dish I've been cooking. It's unique! It takes a Fire Flower and an Egg to fix it. When I first made it, it blew me away! It might help you on your adventures. Please come visit me with those ingredients!♡
 * Tayce T.

Kolorado

 * The ninth letter Mario obtains is another from Kolorado.

How are you, old bean? Smashing, I trust. I'd just like to thank you for helping with that nasty volcano business. Of course, I'm sure you're well aware of my own heroic role in the final fracas. I've lately worried about my dear wife. How she must worry about me as I brave danger! Perhaps it's time I returned home for a while. Feel free to stop by for a spot of tea!

Dear Mario, How are you holding up? It's so sunny in Flower Fields. Peace has returned here. Lily's in her own little world, as usual. Rosie is spreading a rumor that you're interested in her. I hear that Petunia is singing your praises across the land. As you know, I can't move from this spot, but I'm content to watch the Bub-ulbs frolic. Good luck to you, Mario. All of Flower Fields is wishing to the Stars that your dreams will come true.
 * Wise Wisterwood

Red & Blue Goomba Bros.
Goombario, You were a lot stronger then you looked. We figured you were just some punk Goomba hanging around with Mario.

Come home soon!
