Attaching images to email messages can be done in two ways:
- Attachment of an image
2. Add an image to an HTML email
Explore how it can help you boost their experience.
Attachment of an Image
You can add the image as an additional file, which does not affect the HTML structure. It is a simple process, but there is a file size limitation.
Every email client has a maximum file upload size.
When you try to upload a file bigger than 25MB to Gmail, it redirects you to the Google Drive link.
💡Tip: Keep the file size as minimal as possible. So that your receivers can just look at the attachments.
Add an image to an HTML email
Embedding images directly in your email message’s HTML code can be an excellent way for creating a visually stunning email.
There are three primary approaches for embedding images in HTML email:
- CID means Content-ID.
- The inline embedding or base64 images
- Images that are linked or hosted
Attachments with CID (Content-ID)
The word Content-ID (CID) refers to an email attachment that enables images or other files to be added to the email body.
When the email client shows the message, it uses the “CID” URL model to find the attachment’s Content ID and show the embedded image.
Example of JavaScript Code:
This code explains an email message with an embedded image attachment, referring to the attachment within the email’s text format through the “CID” protocol.
The inline embedding or base64 images
Inline embedding, often known as base64 encoding, is the process of adding images or binary data direct into HTML or CSS code.
It lets you add images to your web pages without having to load external files manually.
To use inline embedding, first convert the image file to a base64-encoded string.
You can do this by using web tools or code libraries.
After getting the base64-encoded material, you’re able to use the “data” property to add it directly into your HTML or CSS code.
It is not a chosen form of communication in emails. There are many reasons for this, such as:
- It creates a lengthy string for detailed photos.
- It causes deliverability and spam challenges by increasing the size of your email.
- Some mail suppliers, like Microsoft Outlook, do not show it.
- Once integrated, Base64-encoded text is not editable or scalable.
So, what is the best way to use an image in an HTML email?
Embedding linked or hosted images
When using images in HTML email, it is best to host them on specific cloud services such as Cloudinary, Bunny CDN (Content Delivery Network), or Amazon AWS S3.
When you upload your file to one or both of the services, you will be given a link, which you can then place in the image tag as follows:
Many big companies use this approach with their dedicated resources server.
You can also use the server where your website is hosted, but make sure that the images load quickly; otherwise, the person receiving them will have a bad experience.
Best Practises for Image Embedding in HTML Email
Before starting email marketing, you need to think about a few things.
There are no hard and fast rules, but keeping the following principles in mind can help you create a strong email template:
- For better deliverability and scalability, use linked or hosted images instead of base64-encoded text.
- Reduce the size of your images for use on the web to speed up load times.
- For accessibility, use alt tags to offer an oral description of the image.
- Check your emails across several email clients and devices.
- To guarantee that your images look attractive on multiple screen widths, think about using a responsive email design.
- Use the right image format. JPEG is suggested.
- Instead of developing email newsletter templates from scratch, always use tools.
