Sendgrid to stop changing plain text links?

问题

How to tell sendgrid to stop decorating plain text URLs?

Using sendgrid SDK for Python, if that matters.

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)

For HTML-side this already has an answer:

Is it possible to exclude links from tracking

Tracking still needed for HTML parts of mails.

回答1:

I contacted support and they informed me that I could use Clicktrack SMTP filter with the X-SMTPAPI header.

There are two filter options, one is the enable and disable the click-tracking setting and the other for enabling or disabling click-tracking links in the Plain-Text portion of the message.

The Sendgrid Python client has helper class ClickTracking to control these settings:

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("team@example.com")
to_email = To("test@example.com")
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)

A flask-mail example setting the `X-SMTPAPI' header with clicktrack filter:

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)
