SendGrid邮件发送API，SendGrid支持哪些类型的邮件附件

Question

I'm using next code for send email attachments:

Attachments attachments3 = new Attachments();
Base64 x = new Base64();
String imageDataString = x.encodeAsString(fileData);
attachments3.setContent(imageDataString);
attachments3.setType("image/png");//"application/pdf"
attachments3.setFilename("x.png");
attachments3.setDisposition("attachment");
attachments3.setContentId("Banner");
mail.addAttachments(attachments3);

Here there is setter setType.

Do SendGrid have white list for type of attachment?

For example i can't send.exe or.rar files in another services. I want know prohibitions for SendGrid.

Answer 1

According to their documentation the only limit is 30MB or less.

https://docs.sendgrid.com/api-reference/mail-send/limitations

From having used SendGrid in the past, I would be surprised if they limit what file types you can send.

Answer 2

Just a small precision: The total size of your email, including attachments, must be less than 30MB.

Their recommendation is not to exceed 10MB
