邀請信一定要將邀請的時間（年、月、日、鐘點）、地點、場合寫清楚，不能使接信人存在任何疑慮。例如:“I’d like you and Bob to come to Luncheon next Friday.”這句話中所指的是哪個星期五並不明確，所以應加上具體日期, “I’d like you and Bob to come to luncheon next Friday, May the fifth.”
Dear [Zhang Ying]:
Will you come to luncheon on [Friday, May the fifth], at [twelve o’clock]?
My niece [Mary] is visiting us and I think you will enjoy meeting her. She is a charming, very pretty girl … and very good company! [John and Jane] will be here, and perhaps we can [give a dance] after luncheon. Do say you’ll come!
I know you are interested in [oil painting], so I’m sure you’ll be interested in [Mr. and Mrs. Lin dun]! They are coming here to supper [next Sunday night, October the twelfth], and we’d like you and [Walter] to come, too.
[Mr. and Mrs. Lin Dun] are that very charming couple we met in [London] last summer. They have a wonderful collection of [oil paintings of various stages]; and I understand that Mr. Lin Dun is quite an authority on [oil painting]. I’m sure you and Walter will thoroughly enjoy and evening in their company.
We’re planning supper at six; that will give us a nice long evening to talk. If I don’t hear from you before then, I’ll be expecting you on the [twelfth]!
邀請信包括宴會、舞會、晚餐、聚會、婚禮等各種邀請信件，形式上大體分為兩種:一種為正規的格式 (formal correspondence)，亦稱請柬；一種是非正式格式 (informal correspondence), 即一般的邀請信。邀請信是在形式上不如請柬那樣正規，但也是很考究。書寫時應注意:

親愛的[張營]:
您能在[5月5日星期五中午12點鐘] 來吃午飯嗎？
我侄女[瑪麗]正在我們家中作客，我想您會樂於見到她的。她是個漂亮而聰明的女孩子，……同她在一起是很使人高興的！[約翰和簡]也到這裡來，也許在飯後我們能[開個舞會]，說好，一定得來呀！

我知道您對[油畫]是有興趣的，所以我相信您對林頓夫婦也會感興趣。他們將在[10月12日（下星期日）]來吃飯，我們很希望您和瓦爾特也能同來。
[林頓夫婦]是那麼好的一對夫妻。我們是去年夏天在[倫敦]認識的。他們集有[各個不同時期精美的油畫作品]。我知道，林頓先生在研究[油畫]方面是頗有權威的。我深信，那天晚上您和瓦爾特同他們在一起，一定會很愉快。
我們準備在6點鐘吃晚飯，這樣就能有較長的時間閒談。如果事前接不到您的回信，我就指望你們那天到來。
