Hosted by Mandoline
Every piece is uploaded and hosted for you. No image files to upload or manage.
Most email builders make it easy to link the whole image, but not the parts that matter. Draw a box over each button or headline, and Mandoline gives you email-safe HTML ready to paste.
Drop your newsletter image

Try a sample newsletter
Start with your finished newsletter design. Then:
Step 1
Draw a box over anything that should be clickable, then paste in its link. One link or twenty. The design itself never changes.
Step 2
Email clients are picky, so Mandoline writes the old-school table HTML they respect. One click and the whole block is on your clipboard.
Step 3
Paste it into your email builder's code block and hit send. That's it. Your readers get the design you made, links and all.
The method behind it
Mandoline cuts around each box you draw, links that piece, and rebuilds the pieces as one newsletter.
Once the links are set
Mandoline hosts the pieces and gives you email code that works with any builder that accepts custom HTML.
Every piece is uploaded and hosted for you. No image files to upload or manage.
Copy one block of email code into any builder that accepts custom HTML.
Direct integrations
Mailchimp is available now. Connect your account and Mandoline can upload the pieces to File Manager and create a draft campaign for you. More direct integrations are coming.

Try Mandoline ↑One unique image counts as one project. Changing links or publishing it again doesn’t use another project.
You slice it. Image maps and CSS positioning are unreliable in email clients, so the approach that holds up across the common ones is cutting the image into pieces and wrapping each piece in a link. Professional newsletters have done it this way for decades. Mandoline automates the cutting, the pixel math, and the HTML.
Yes. The generated HTML is built for how email clients actually render: table layout, integer pixel widths that sum exactly to the table width, and none of the CSS that desktop Outlook mangles. The same code holds up in Gmail, Apple Mail, and the rest, and the rules come from a battle-tested production email, not a blog post.
Slicing runs in your browser. If you're signed in, your project and its image are saved to your account so you can reopen them from any device; delete the project and they're gone. Publishing uploads the finished slices to Mandoline's hosting, or to Mailchimp if you connect it.
No. Mandoline hosts the slices for you and gives you one block of HTML to paste into any email builder that accepts custom code. Connecting Mailchimp also lets Mandoline upload the pieces and create a draft campaign for you.
One unique image, identified by its content, not its filename. Fixing a typo in the copy means a new image and a new project; re-drawing regions or re-publishing the same image is always free. One catch: design tools rarely export the same file twice, so re-upload the file you already have instead of re-exporting.
A tall PNG or JPG around 1200–2400px wide works well. At publish time you choose the email display width (600px default, 320–1200 allowed) and Mandoline handles the pixel math.
