If proof were needed, witness the fuss caused by Big's missive to Carrie in the ultimate women's film, Sex and the City.
Just months after ceremoniously standing her up at the altar, Mr Big won the famous fictional journalist back with a few words.
"Ever thine. Ever mine. Ever ours. BIG." he wrote. Women love that kind of stuff.
In fact they weren't Big's words at all but those of Beethoven, and copied from Carrie's favourite anthology, Love Letters Of Great Men.
After the film, hundreds of women tried to purchase this book, only to discover it was fictional.
But a publishing company caught wind of the women's despair and asked Ursula Doyle to turn the imaginary book into a reality.
After wading her way through mountains of paper, her final collection includes letters from such famous men as Mozart, Nelson, Keats and Byron.Having studied the best, and the worst, of the world of romantic letters, Ursula has a few tips for future Cyranos.
"You don't have to be a great writer to write a great love letter," she says. "Sincerity will always shine through. You can always tell if it comes from the heart."
Love Letters Of Great Men is published by Macmillan, priced £9.99.

Express yourself
If you're planning a love letter of your own, here are some useful do's and don'ts from the masters.

DO...
...aim to impress
"You know I would with pleasure give up all here and beyond the grave for you,"
wrote Lord Byron to married Lady Caroline Lamb in 1813.
...flatter your subject
"Unlovely objects are all around me, excepting thee; the charms of all the world appear to be translated by thee,"
wrote William Congreve to Mrs Arabella Hunt in the 17th century.
...charm the lady
"Tell me that you are well, tell me that you little son is well, then tell me that your very dog (if you have one) is well. Defraud me of no one thing that pleases you, for whatever that is, it will please me better than anything else can do,"
wrote Alexander Pope to Lady Wortley Montagu, June 1717.
...be amusing
"Do catch them in the air - those 2999 1/2 little kisses from me which are flying about, waiting for someone to snap them up,"
wrote Mozart to his girlfriend Constanze on June 6, 1871.
...wear your heart on your sleeve
"Oh Phoebe, I want thee much. Thou art the only person in the world that ever was necessary to me. Other people have occasionally been more or less agreeable; but I think I was always more at ease alone than in anybody's company, til I knew thee,"
wrote Nathaniel Hawthorne to his wife Sophia in the 19th century.

DON'T...
...be bitter
"But the time will come when you will sigh for any heart that could be fond; then you will recall to your memory the passionate heart you have forfeited and the genius you have betrayed," wrote Benjamin Disraeli to Mary Anne Wyndham Lewis, February 7, 1839.
Fawn over the recipient: "(I'd be] Only too happy if she deign sometimes to cast a pitying look upon her slave,"
wrote Victor Hugo to Adele Foucher, January 1820.
...depress your reader
"For myself I have been a Martyr the whole time,..I appeal to you by the blood of that Christ you believe in; Do not write to me if you have done anything this month which it would have pained me to have seen,"
wrote Keats to Fanny Brawne, 1820.
...bore them to tears
"Never was a passion more justified by reason than mine. Is it not true, my dear Sophie, that you are very amiable?"
wrote Denis Diderot to Sophie Volland, July 1759.
