You've Got Mail goofs

When signing on to AOL, the monitor's on-screen readout does not match the noise of the connection being established.

In the email Joe is reading following the café confrontation, the line shown — "I hope that you didn't blow me off casually." — is at odds with the voice-over.

When Kathleen goes into Starbucks and orders a Tall Caramel Macchiato, the barista in fact hands her a Grande-sized cup.

Kathleen says "we don't talk about anything personal, so it will be really easy to stop seeing him because I'm not." However, after speaking with his father and grandfather about the competition and Kathleen's shop, Joe emails Kathleen about his father's forthcoming marriage to a woman called Jillian, who trained in decorating at Caesar's Palace. This is personal information, and since Joe's father is the chief executive of Fox Books, such details would be available to read online.

While Joe Fox is preparing martinis for himself and his father, he twice drops an olive into the second glass, although the glass does not, in fact, contain two olives.

At a party where Kathleen realises that Joe is, in fact, Joe Fox, she is talking with him as he helps himself to the caviar garnish from a plate. He scrapes a portion of the garnish away from the rim of the plate, and when he does it again a moment later the caviar is back in precisely the same position it occupied before he first removed it.

The clock behind the counter in Kathleen's shop displays exactly 4:30 for the entirety of the slightly more than two minutes whilst Joe is buying the books. It shows different times in other scenes, so it isn't stopped.

During the dinner party, when Kathleen confronts Joe about his identity, the food on his plate repeatedly changes.

Whilst Joe is preparing martinis on his father's boat, he pops the olive into the glass twice.

While Kathleen waits in the café for NY152 to turn up, she adjusts the book and the flower and eventually tucks the flower inside the book; when Joe arrives she lifts the book to hide her face, but the flower is now sitting on top of it and the book is in a different position.

In the scene where the shop staff are selling off items before closing, Kathleen places a blue toy into the customer's bag twice.

As Kathleen waits to meet NY152 for the first time, Joe arrives and places his coat over the back of the chair on two separate occasions.

When Joe visits Kathleen at her flat while she is unwell, he asks her to sit at the table. When she sits, there's a sizeable pile of tissues on the table, but in later shots they have disappeared.

While Joe and Kathleen are sitting at the pavement café, a woman pushing an orange shopping trolley walks past twice.

When Joe is at the Shop Around the Corner with Annabelle and Matt, they go to the till to pay. We first see Christine (Heather Burns) behind the till serving a customer. The camera immediately cuts back to Joe, and Christine is now behind him attending to a different customer. The shot then returns to Kathleen, where Christine is again behind the till, this time leaving to help that other customer. When the camera goes back to Joe, Christine is once more behind him assisting a customer, with no time for her to have walked between those positions.

When Frank leaves the flat at the start, the computer is on a table at the foot of their bed. After Kathleen sees him off as he exits the building and hurries back to sit at the computer, it has been relocated to a table facing the sitting-room furniture.

When Joe visits Kathleen, who is unwell, she sits at the table while he fills the vase with flowers; the table runner at the end furthest from her alternates between lying flat and becoming creased.

During Kathleen's story-time scene, the placement of her hat repeatedly shifts.

At the start, when the camera comes in through the window of Kathleen's flat and pans to show her asleep in bed, her bathroom's pocket-door is fully open and the light is off. Later, as Frank rouses her with news that Solitaire must be removed from employees' computers in another state, the camera pans back to him and passes the bathroom again — the pocket-door is now half-open and the light is switched on.

Joe Fox's explanation of Krikštatėvis (1972)'s significance would have been met with the error message 'You have exceeded the send limit'.

(about six minutes in) When Joe logs on, the screen displays "You have mail". At the same moment Joe says, "You've GOT mail." Seconds later, when Kathleen logs in, the same sequence repeats, including in Kathleen's voiceover (i.e. the email she sent to Joe). Both times the on-screen text uses "have", not "got".

When composing a message about Krikštatėvis (1972), Joe types "Don't lose you're nerve." It ought to read, "Don't lose your nerve."

Although this is a grammatical mistake, it is a very common one — you can encounter it several times a day if you spend any time reading blogs or online comments. Thus, it is not a Character error Goof but rather a realistic detail.

Kathleen sends Joe an email describing how she'd just told someone off at the café. Joe reads her message and signs off; the AOL voice intones "Goodbye". Yet when he replies, he simply starts typing without signing back on.

AOL permits composing emails while offline.

When Joe picks up the book Kathleen has brought to the café and says 'Pride and Prejudice — I bet you just love this book', the cover is in fact that of Jane Austen's Persuasion.

On several occasions it is made clear that a key is required to enter Kathleen's block of flats. However, when she leaves the building to meet NY152 for the last time, she has no keys (and neither a handbag nor pockets).

While Joe Fox is in The Shop Around The Corner, the 'open/closed' sign is set with the 'open' side turned inwards and the 'closed' side facing outwards.

Throughout the film, the laptops are never shown with any cables attached. Although they could be powered by internal batteries (so no mains lead is needed), they would not have been able to access the internet without being physically connected to a telephone line. This was well before the age of Wi‑Fi and widespread broadband; at the time a computer had to be directly linked to a telephone line for the modem to dial up to the internet (the dialling noises can be heard at various points). It’s possible they were reading or composing e‑mails offline, but on a number of occasions they are clearly online despite no cables being connected to the laptops.

When Kathleen shuts the shop for the final time, the sign announcing that they are closing down after 42 years is turned inwards so it cannot be read from the street.
