Nevertheless, there’s no one means to do that. Do you hyperlink out to the picture on a CDN? Do you embed it and reference it through a CID tag? Perhaps as a linked picture? Which one do you have to select?
On this put up, we’ll present you embed a picture in an e-mail with all these choices—plus, we’ll deal with the professionals and cons of every. For Twilio SendGrid customers, we’ll present you ways you’ll use these choices with SendGrid, so you may take a look at your wants and your viewers and make up your thoughts.
Let’s begin with the mysterious CID.
3 methods to embed pictures in emails
1. CID embedded pictures (inline pictures)
To me, CID (or Content material-ID) feels outdated, and one thing very akin to working with emails in Outlook. That apart, it’s nonetheless an choice, and we assist it in our consumer libraries.
CID pictures work by attaching the picture to the e-mail you ship after which utilizing normal HTML picture tags that reference that picture to finally embed it within the e-mail when the consumer opens it.
Utilizing the SendGrid Node.js consumer library, we’d connect the picture like so:
var params = {
smtpapi: new sengrid.SmtpapiHeaders(),
... //some vars eliminated right here!
recordsdata: [
Buffer)
],
file_data: {},
headers: {}
};Then, in your HTML template, you’ll embed the picture on this means:
<html>
<physique>
<img src="cid:myimagecid"/>
</physique>
</html>Wow, proper? No.
The issue with CID embedded pictures is that they don’t all the time show correctly in e-mail shoppers. The rule of thumb is that CID embedding will work fantastic in most desktop e-mail shoppers, however most probably by no means in web-based e-mail shoppers, comparable to Gmail or Yahoo! Mail.
Bummer.

Embedding a picture in an e-mail first requires that you’ve got a model of the stated picture as a Base64 encoded string. As soon as your encode your picture, leap into your template, or no matter HTML you ship out, and embed it utilizing an ordinary HTML picture tag:
<img alt="My Picture" src="information:picture/jpeg;base64,/9j/4S/+RXhpZgAATU0AKgAAAAgACAESAAMAENkDZ5u8/61a+X...extra encoding" />You then’re performed. Ship away.
