发送电子邮件的最佳时间

Today in email marketing, the time that an email is sent has a high impact on user engagement. Sending at an optimal time can help drive more successful and effective campaigns. In order to send at the best time, you need to have a good understand of your users’ email engagement pattern. Sending right before the time a user interacts with their inbox can lead to the highest chance of engagement.

如今在电子邮件营销中，电子邮件的发送时间对用户的参与度有很大的影响。在最佳时间发送可以帮助推动更成功和有效的活动。为了在最佳时间发送，你需要很好地了解你的用户的电子邮件参与模式。在用户与他们的收件箱互动的时间之前发送可以导致最高的参与机会。

We analyzed user email open and click behaviors across thousands of our participating customers, billions of users, and hundreds of billions of email events across a three month window in 2021 and found out that the engagement pattern not only varies by brand and geolocation, but also, most importantly, from individual to individual.

我们分析了2021年三个月的时间里，我们成千上万的参与客户、数十亿用户和数千亿的电子邮件事件的用户电子邮件打开和点击行为，发现参与模式不仅因品牌和地理位置而异，而且最重要的是，因人而异。

Having a system that constantly monitors user behaviors, adaptively adjusts the strategy according to user feedback, and reasonably balances between exploration and exploitation can truly help lift email engagement over time. This is the general rationale behind our Einstein Send Time Optimization feature. Here’s a deep dive into the analysis we did to build the algorithm that drives the feature for our customers.

拥有一个不断监测用户行为的系统，根据用户反馈自适应地调整策略，并合理地平衡探索和利用，可以真正帮助提升电子邮件的参与度。这就是我们爱因斯坦发送时间优化功能背后的一般原理。下面是对我们为客户建立驱动该功能的算法所做的分析的深入探讨。

First of all, let’s look at when users open their emails throughout the week.

首先，让我们看看用户在整个一周内何时打开他们的电子邮件。

The chart below shows an aggregated view of hourly email opens for the entire week across all participating customers. With respect to Central time (CT), mornings (especially 8am ~ 10am) consistently have higher number of opens compared to other times of the day, and weekdays tend to have more opens than weekends. This is a good start to understand general behavior; however, is that enough? Each of our cus...
