在html电子邮件中发送个性化图像的推荐方法是什么？ [英] What is the recommended way for sending personalized images in html emails?

问题描述

我知道类似的问题已经被问到了，但是答案几乎总是一样的：你需要在服务器上共享图像，并从电子邮件中链接到它。

为了我的目的，我不能这样做。

需要为每个发送电子邮件的用户个性化图像（因此电子邮件将为每个用户动态生成，并不总是相同的，我不能分享图像 - 因为它将改变，而且为了避免披露用户的信息）。

你有没有遇到这种情况？我应该用附件还是base64编码图像？想法/经验？

解决方案

HTML体必须使用内容id（cid）引用图像：< img src =cid：xyz> ，其中xyz是附件内容标识（Content-ID）MIME标题的值。

如果要以MIME格式直接创建消息，请确保将附件添加到消息中，并将其Content-ID MIME标题设置正确。如果您是Outlook对象模型或MAPI，则必须在图像上设置PR_ATTACH_CONTENT_ID属性。

I know similar questions have already been asked but the answer is almost always the same: you need to share the image on a server and link to it from within the email.

For my purpose I cannot do that.

The image needs to be personalized for each user I send an email to (so the email will be dynamically generated for each user and will not always be the same. I cannot share the image -- since it will change but also for avoiding disclosure of users' information).

Have you ever encountered this scenario? Should I go with attachments or base64 encoding of images? Thoughts/experiences?

解决方案

The HTML body must refer to the images using the content id (cid): <img src="cid:xyz">, where xyz is the value of the attachment content id (Content-ID) MIME header.

If you are creating the message directly in the MIME format, make sure the attachment is added to the message and its Content-ID MIME header is properly set. If you are Outlook Object Model or MAPI, you must set the PR_ATTACH_CONTENT_ID property on the image.
