Characters who have reached their Birthday will send you a mail with their Special Dish and one or more additional gifts. Characters will always mention these miscellaneous gifts in their letter, but rarely the special dish that is also attached.
It is not required to own the specific characters, as players will receive the celebratory mail, regardless. However, the mail is only sent on log-in of that specific day and will not be able to be received the day after.
- A character's Birthday Mail does not adhere to the server's daily reset timer; The Mail will be received when the server's time passes 00:00 (Midnight).
- A character's Birthday Mail is only available for that particular day, from 00:00 to 23:59. The player must log in to the game during that time period to receive the mail. If a player logs on at 00:01 the following day, despite being in the same server reset cycle, the mail will not be received.
- Currently, a character's Birthday Mail is the only way to receive their special dish if the player does not own the character in question. There are a couple of exceptions to this rule however, such as the special dishes obtained from unlocking different endings of Hangout Events.
The Traveler's birth date depends on the player's choice in their profile customization and cannot be changed again once set. Once the Traveler celebrates their birthday, the Dev Team, via the mailing system, will send birthday wishes, along with a special gift of one Cake for Traveler, which rewards one Fragile Resin and an unusable version of the cake when used.
On top of this, any characters the player currently has will have their "Birthday" voice-over permanently unlocked. Future characters that the player obtained after their birthday has passed will still unlock their "Birthday" voice-over.

- If the player's birthday is set to February 29, their birthday mails will be sent on February 28 during non-leap years.
- This is the same with Bennett, as he celebrates his birthday on February 28.
- Itto and Paimon share the same birthday, June 1.
- Paimon's birthday mail does not include a special dish, since she is not a playable character able to cook.
- Ningguang is the only character that directly names the special dish attached in her letter, although Xiangling comes close in her 2020 letter ("Wanmin Restaurant's authentic Boiled Fish"). Other characters refer to their dish without naming it, only mention they cooked something, only mention having a meal together, refer to another edible item in the mail instead, refer to other food entirely, or do not refer to food in any way at all.
- Characters who have sent more than one of their special dish:
- Characters who have sent dishes that can be cooked in-game besides their own Special Dishes:
- Characters who have sent consumable Food that cannot be cooked:
- Characters who have sent ingredients used in recipes and other items known to be edible (including unconventional ingredients, but only if the sender intends for them to be ingredients), besides their Special Dishes:
- Diona 2021: Loach Pearl (used in one of her concoctions)
- Beidou 2021: Violetgrass
- Jean 2021: Philanemo Mushroom
- Paimon 2021: Sugar, Flour, and Slime Condensate (to be used in a slime-flavored birthday cake)
- Lisa 2021: Calla Lily
- Barbara 2021: Dandelion Seed
- Hu Tao 2021: Violetgrass
- Tartaglia 2021: Chilled Meat
- Amber 2021: Dandelion Seed
- Kamisato Ayaka 2021: Sakura Bloom
- Sayu 2021: Unagi Meat
- Xiangling 2021: Pufferfish
- Keqing 2021: Qingxin
- Ganyu 2021: Qingxin
- Diona 2022: Luminescent Spine (to be used in one of her concoctions)
- Qiqi 2022: Wheat
- If the player has 20 Qingxin Seed in their Seed Dispensary when receiving Ganyu's 2021 birthday mail, they would be unable to claim any of the mail's rewards and would be met with a "No space left in inventory for another Qingxin Seed. Please free up some space and try again." message. As it was not possible to delete seeds from the dispensary, the player needed to plant at least 1 Qingxin in their Serenitea Pot before being able to claim the rewards.
- Itto has the longest message for the Traveler in his "Birthday" voiceline.
- The Raiden Shogun has two birthday voicelines, one from The Shogun ("Birth Date") and one from Ei ("Birthday").
- Yae Miko also has a birthday voiceline called "Birth Date."
- Xingqiu also has two separate birthday voicelines for the Traveler: "Birthday: Wishing," and "Birthday: Customs."
