While email newsletters that have images look stunning and perform better, not everyone knows how to upload images to their emails, what the differences are between linked and embedded images, how these affect send costs and - more importantly - why.
So here is a quick guide to all of the above

Once you’ve mastered the essentials of uploading, storing and making use of images and have sent off a newsletter or two; you should notice that often the images within these don’t display once they reach the destination inbox and that there is a difference in the send credits charged for those newsletters - depending on whether you have linked or embedded your images.
Embedding images will come at a slightly higher cost in send credits - but this is for good reason:
Many email clients block images by default for security and privacy purposes. With image blocking so common these days, email marketers make use of either linked or embedded images, depending on their needs.
Linked images - These are not part of the message itself and are usually hosted by the message sender and referenced in the message body. The main advantage of linked images is that the message body remains small (in file-size). The main disadvantages are that such messages cannot be viewed off-line, and they usually have a limited lifespan, vanishing once removed from the server. So when you link an image in your GraphicMail newsletter, these images won’t show for the recipient unless they request the server to download them. If however they have marked you as a trusted sender, they can change the settings so they will always have the images downloaded automatically when they receive a newsletter from you.
Embedded Images - Unlike linked images, embedded images are part of the message itself. A message with embedded images can be viewed off-line and remains intact over time, as images are permanently attached to it. What differs is that the image itself is actually encoded, inside the message. You are not reliant on a web connection to view the images, because your recipients have it all on your system. As wonderful as that sounds the downside is a big increase in email size compared to downloading just the HTML and then the images afterwards. So embedding is clearly very different from merely including images in one's newsletter design, but do keep in mind that a message may contain regular attachments and embedded images at the same time. There is a slightly higher spam risk when embedding images, especially if they are big, so make sure to use the spam checker before sending off your newsletter campaign.
Are you experiencing that your images often get blocked by Email Clients?
Desktop and Webmail Clients block email newsletter images in different ways. For example, one email client might block images by default, another might require the user to turn on image blocking manually.
Take a look at the current default settings both for Desktop Email Clients and Webmail Clients, as discussed in our sending guide.
Image costs: Embedded vs Linked
Using images in your newsletter will amend the amount you pay per send. Your account has a certain number of 'send credits' and each send uses a single credit. If you want to send attachments with your email, we may charge more than one 'send credit.'
For example, if you want to send attachments (like excel files or word docs) or if you want to send the images along with your emails (embedding), we'll need to use more bandwidth to send those larger files.
But don't worry, we'll inform you before the send is executed and state how many credits it would take to send your attachments.
Including images in your newsletters is a tried and true method of improving your email’s click-through rate, but since there is such a great deal of inconsistency between which browsers will actually display images, you shouldn’t rely on these alone to communicate your message. Avoid replacing too much text with images and make sure your email design gets the point across all by itself. And a last word on the matter: Be sure to add image alt text for those who do not see your images…
