3 methods to embed photographs in emails
1. CID embedded photographs (inline photographs)
To me, CID (or Content material-ID) feels outdated, and one thing very akin to working with emails in Outlook.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 possibility, and we help it in our consumer libraries.
CID photographs work by attaching the picture to the e-mail you ship after which utilizing normal HTML picture tags that reference that picture to ultimately embed it within the electronic mail when the person 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’d embed the picture on this manner:
<html>
<physique>
<img src="cid:myimagecid"/>
</physique>
</html>Wow, proper? No.
The issue with CID embedded photographs is that they don’t at all times show correctly in electronic mail purchasers. The rule of thumb is that CID embedding will work advantageous in most desktop electronic mail purchasers, however more than likely in no way in web-based electronic mail purchasers, similar to Gmail or Yahoo! Mail.
Bummer.
