关于此解决方案
使用 Google 表格中的数据自动填充电子邮件模板。通过
系统会通过您的 Gmail 账号发送电子邮件,以便您能够回复
收件人回复。
重要提示 :此邮件合并示例受所述电子邮件限制的约束
Google 服务的配额 部分。
工作原理
您创建了 Gmail 草稿模板
对应于 Google 表格电子表格中的数据。每个列标题
表示占位符标记。脚本会将
每个占位符从电子表格映射到相应占位符的位置。
占位符标记。
Apps 脚本服务
此解决方案使用以下服务:
Gmail 服务 - 获取、读取、
并将您要发送给收件人的电子邮件草稿发送出去。
电子表格服务 - 填写电子邮件
包含个性化信息的占位符
向每位收件人发送邮件。
前提条件
如需使用此示例,您需要满足以下前提条件:
Google 账号(Google Workspace 账号可能
需要管理员批准)。
可以访问互联网的网络浏览器。
设置脚本
创建 Apps 脚本项目
点击以下按钮,复制
Gmail/表格邮件合并 电子表格示例。
此 API 的 Apps 脚本项目
解决方案。
复制
在复制的电子表格中,将“收件人” 列更新为“电子邮件地址”
您想要在邮件合并中使用的地址。
(可选)添加、修改或移除列,以自定义您需要的数据
添加到电子邮件模板中。
如果您更改收件人 或电子邮件
已发送 列,则必须更新
Apps 脚本项目。您可以打开 Apps 脚本
从电子表格中创建项目的
点击扩展程序 >
Apps 脚本 。
创建电子邮件模板
在您的 Gmail 账号中,创建电子邮件草稿。添加数据
从
电子表格,请使用与列名称对应的占位符
用大括号括起来,如 {{First name}}
。
如果您为电子邮件中的文本设置了格式,则还必须设置占位符的格式
括号。
占位符区分大小写,而且必须与列标题完全匹配。
复制电子邮件草稿的主题行。
运行脚本
在电子表格中,点击 Mail Merge (邮件合并)>
发送电子邮件 。您可能需要刷新此自定义菜单的页面
。
出现提示时,为脚本授权。
如果 OAuth 同意屏幕显示以下警告:“此应用未经验证”,
选择高级 > 以继续操作
前往“{Project Name}”(不安全) 。
点击 Mail Merge (邮件合并)> Send Email (发送电子邮件)
。
粘贴电子邮件模板的主题行,然后点击确定 。
如果您对工作表应用了过滤器,脚本仍会通过电子邮件
但不会添加时间戳。

修改
您可以根据需要随意修改邮件合并自动化操作。
以下是您可以对源代码进行的一些可选更改。
添加“密送”、“抄送”、“回复”或“发件人”参数
示例代码包括许多其他参数,目前
这样,您就可以控制要发送电子邮件的账号的名称
发件人、回复电子邮件地址以及密送和抄送电子邮件地址。
移除正斜杠,激活要添加的参数
//
。
以下示例是 sendEmails
函数:
GmailApp.sendEmail(row[RECIPIENT_COL], msgObj.subject, msgObj.text, {
htmlBody: msgObj.html,
bcc: 'bcc@example.com',
cc: 'cc@example.com',
from: 'from.alias@example.com',
name: 'name of the sender',
replyTo: 'reply@example.com',
// noReply: true, // if the email should be sent from a generic no-reply email address (not available to gmail.com users)
在上面的示例中,noReply
参数仍被注释掉
因为设置了 replyTo
参数。
在电子邮件中包含 Unicode 字符
如果您想在电子邮件中包含 Unicode 字符,例如表情符号,请按以下步骤操作:
必须更新代码才能使用邮件服务,而不是 Gmail 服务。
在示例代码中,更新以下行:
GmailApp.sendEmail(row[RECIPIENT_COL], msgObj.subject, msgObj.text, {
将该行替换为以下代码:
MailApp.sendEmail(row[RECIPIENT_COL], msgObj.subject, msgObj.text, {
