Sendgrid 停止更改纯文本链接？

如何告诉 sendgrid 停止修饰纯文本 URL？

使用适用于 Python 的 sendgrid SDK（如果有的话）。

sendgrid.SendGridClient(username, pwd)
mail = sendgrid.Mail()
mail.set_html(html_message)
mail.set_text(text_message_with_urls)  # <-- urls are here
...
sendgrid_client.send(mail)

对于 HTML 端，这已经有了答案：

是否可以从跟踪中排除链接 https://stackoverflow.com/questions/28873632/is-it-possible-to-exclude-links-from-tracking

邮件的 HTML 部分仍需要跟踪。

我联系了支持人员，他们告诉我我可以使用Clicktrack SMTP 过滤器 https://sendgrid.com/docs/for-developers/sending-email/smtp-filters/#filter-clicktrack与X-SMTPAPI header.

有两个过滤器选项，一个是启用和禁用点击跟踪设置，另一个用于启用或禁用消息纯文本部分中的点击跟踪链接。

Sendgrid Python 客户端有帮助程序类 ClickTracking 来控制这些设置：

import json
import os

from sendgrid import SendGridAPIClient
from sendgrid.helpers.mail import *

sendgrid_client = SendGridAPIClient(os.environ.get('SENDGRID_API_KEY'))
from_email = Email("[email protected] /cdn-cgi/l/email-protection")
to_email = To("[email protected] /cdn-cgi/l/email-protection")
subject = "Sending with ClickTracking plain text disabled"
content = Content(MimeType.text, "Test URL: https://www.google.com")
message = Mail(from_email, to_email, subject, content)

tracking_settings = TrackingSettings()
tracking_settings.click_tracking = ClickTracking(enable=True, enable_text=False)
message.tracking_settings = tracking_settings

response = sendgrid_client.send(message=message)
print(response.status_code)

使用点击跟踪过滤器设置“X-SMTPAPI”标头的烧瓶邮件示例：

from flask_mail import Mail
from flask_mail import Message

mail = Mail(app)
subject = "Sending with clicktrack plain text disabled"
body = "Test URL: https://www.google.com"
headers = {"X-SMTPAPI": json.dumps({
  "filters" : {
    "clicktrack" : {
      "settings" : {
        "enable" : 1,
        "enable_text" : False
      }
    }
  }
})}
message = Message(subject=subject, body=body, extra_headers=headers)
mail.send(message)
