二 | COPENHAGEN, Denmark -- Denmark’s deputy prime minister and economy minister announced Monday he was leaving politics and stepping down as head of the center-right Liberal Party to spend more time with his family.The Liberals, however, are staying on in the three-party governing coalition, which has been in office since December 2022. For now, Defense Minister Troels Lund Poulsen would take over Ellemann-Jensen’s posts and take on the roles of deputy prime minister and economy minister.A visibly moved Ellemann-Jensen said Monday he was taking the consequences following internal party criticism over dwindling support. He said he is resigning because he didn’t want to stand in the way of his party’s revival. The party had seen support plunge from 24.6% in September 2019, when he became party leader, to 8.7% in an Oct. 3 opinion poll.Critics also alleged that Ellemann-Jensen was too weak of a figure in a government where Prime Minister Mette Frederiksen and Foreign Minister Lars Løkke Rasmussen were taking up much of the limelight."I am taking this decision because it is the right thing for the Liberal Party,” Ellemann-Jensen said and insisted his sick leave was not a factor in his decision. Earlier this year, he was on a five-months sick leave following a medical check-up. Senior party member Stephanie Lose will assume the party leadership until a party convention next month. On Aug. 22, a day after Ukrainian President Volodymyr Zelenskyy had thanked Danish lawmakers for providing Kyiv with F-16 warplanes, Ellemann-Jensen swapped posts with Lund Poulsen. Ellemann-Jensen became economy minister while Lund Poulsen became defense minister. During Ellemann-Jensen's sick leave, Lund Poulsen had acted as defense minister.Frederiksen announced a majority coalition that crosses the left-right divide on Dec. 15, 2022, following the Nov. 1 general elections. It was the first time in 44 years that such a centrist government had been formed, bringing an end to the two blocs that have opposed each other for decades. The Liberals joined Frederiksen's center-left Social Democrats and the centrist Moderate party headed by Foreign Minister Lars Løkke Rasmussen — a former prime minister who once headed the Liberal Party but left it and created the centrist Moderates.Ahead of the 2022 election, the Liberal Party had splintered. Løkke Rasmussen had created a new party as did former immigration minister Inger Støjberg, who then was the Liberal Party deputy leader. After the fracturing, Ellemann-Jensen had tried to rebuild the party but the two newcomer parties had eaten away support for the Liberals.。看着不舒服，也带着隐私和合规上的隐患。邮件群发单显，就是用来解决这件事的——但它对不同邮箱，用法和意义不太一样。

什么是邮件群发单显?

单显，意思是"单独显示"。邮件群发时，系统在后台给每个收件人单独生成一封邮件，收件人（To）字段里只出现他自己的邮箱，看不到其他人的地址。对收件人来说，这封邮件看着就像只发给了"我"一个人。这个功能，最常见于个人邮箱和企业邮箱的发送界面——那里通常有一个"群发单显"的勾选框，勾上它，就能达到 1 对 1 的效果。邮件群发单显怎么用？为什么大批量发送还是得靠专业平台

个人邮箱、企业邮箱怎么用群发单显

做法很简单：在写信页面把"群发单显"勾上，收件人栏正常填多个地址，发出去之后，每位收件人收到的那封，To 里只会显示他自己。它主要解决了两件事： · 保护隐私：不让一批客户邮箱互相暴露，既专业，也少踩数据保护的雷。 · 观感更干净：收件人看到的是"只发给我"的邮件，而不是一长串名单，打开的意愿通常会高一些。对小批量、偶尔一次的发送——比如给十几位同事发会议通知——勾一下单显就够用了。

U-Mail邮件营销平台：为什么"不需要"群发单显

这里有个容易混的点。U-Mail邮件营销平台采用的是 1 对 1 大批量发送机制：导入名单、写好内容、设置好变量（称呼、公司名等）之后，平台给每个收件人单独生成邮件、单独投递，To 字段天然就只含本人。也就是说，U-Mail的发送方式本身就是"单显式"的，这是底层逻辑，不是某个要手动打开的开关。所以在U-Mail里，你不会去专门找一个"群发单显"按钮——它已经把 1 对 1 这件事做掉了。也正因如此，每个收件人拿到的称呼、内容都可以是专属的，不需要额外设置。

但大批量发送，个人/企业邮箱单显效果会差

群发单显对个人邮箱、企业邮箱来说，是个"小批量够用"的功能。

三 | 一旦量上来，它的短板就明显了： · 发送量受限。个人邮箱和普通企业邮箱每天能发的数量有限，大批量的话容易被限流、拦截，严重的还会被限制发信。 · 通道信誉一般。这些邮箱的发送通道是通用型的，大批量群发很容易被接收方判为垃圾，进箱率跟着往下掉。 · 稳定性要自己扛。

四 | 退信、失败重试、发送速度，都得自己处理，量一大就容易出问题。 · 批量管理麻烦。大批量时维护名单、退订入口、个性化变量都不方便，很容易顾此失彼。所以"群发单显"对普通邮箱只是应急的小招；真要稳定、可个性化的大批量发送，还是得交给专业邮件营销平台。

对照一下：两种路子怎么选

对比维度	个人 / 企业邮箱（勾单显）	U-Mail（1 对 1 大批量）
适用规模	小批量、偶尔发送	大批量、常态化发送
是否需要勾单显	需要手动勾选	本身即 1 对 1，无需设置
进箱表现	量大时容易下滑	独享群发通道，信誉相对可控
个性化能力	变量能力有限	支持变量替换，内容可专属
批量管理	需自行维护名单与退订	名单、退订、统计一体化
