One row of data should become a 9:16 story, a 4:5 feed post, a 16:9 email hero, and a 1:1 avatar, without a designer touching any of them.
Multi-format personalized assets are individual, data-driven creative pieces rendered for every aspect ratio a recipient might share, from the same record and the same template. Multi-format means one person's numbers arrive as a vertical story, a square post, a widescreen email image, and a PDF, each on-brand, each generated at the same time.
One aspect ratio is not a campaign
Here is the opinion: if your personalized asset only exists in one size, you did not make a personalized asset. You made an email attachment. The recipient opens it on a phone, feels the recognition, goes to share it, and discovers it crops badly on Instagram, dies in a LinkedIn preview, and looks like a billboard shoved into a TikTok frame.
Most brands ship one hero image because that is what the design team had time to build. It is a production decision dressed up as a creative one. The person you just flattered now has to choose between posting something ugly or posting nothing, and they choose nothing.
The StackAdapt and Ascend2 State of Personalization in Digital Marketing report, fielded across 468 North American marketers, found that 93 percent of brands believe AI is improving personalization, yet only one in five have fully integrated it across channels. The gap is not intent. It is the ability to make one idea show up correctly everywhere.
The share happens where you did not render
A personalized asset earns its keep at the moment of sharing, and sharing is channel-specific. Stories want 9:16. Feeds want 4:5. Email clients want 16:9 and a PDF for the person who forwards it to their boss. Profile pictures and community badges want 1:1. If you rendered one of these, you covered one of the four places the share could happen.
This is why so many campaigns with strong data still stall. We wrote about the screenshot test in if nobody screenshots it, your recipient experience design failed, and the multi-format problem is the quiet reason many assets fail that test. People do not screenshot what will not fit where they want to post it.
The design objection is real: four ratios is not one layout resized, it is four compositions. Type hierarchy shifts, the data visualization moves, the logo lockup changes position. Done by hand, that is four times the design work multiplied by every recipient, which is why it never gets done. The fix is to stop treating layouts as files and start treating them as systems, the argument in personalized digital assets at scale require HTML, not InDesign.
A personalized asset that only exists in one aspect ratio is a compliment the recipient cannot repeat.
Precision rendering makes every ratio free
Ditto is a cloud-native rendering engine built by DBC. Structured data goes in, HTML and CSS templates define the layout, and each recipient gets a unique on-brand asset out. The part that matters here is that an HTML template is responsive by nature. A designer builds one system with rules for how elements reflow at 9:16, 4:5, 16:9, and 1:1, and the engine renders all four for every row, as PNG, JPG, or PDF.
Nothing about this is generative. The same record produces the same output every time, which is what brand and legal teams need before they approve anything. That is the difference between one template, four aspect ratios, one row per person, zero manual exports and a designer opening 7,000 files on a Sunday. Creators and their partners feel this first, which is why the Ditto for creator content page leads with stories, feed posts, and profile-ready formats from a single dataset.
Think of it like a broadcast mix in music. The engineer does not re-record the song for radio, vinyl, and earbuds. One master, several deliverables, each tuned for where it will be heard. Multi-format personalized assets are the same discipline applied to campaign creative.
Seven thousand assets, every format, one launch
The proof is Spotify Songwriter Wrapped. Spotify had the data on which songwriters wrote the year's most-streamed songs. Ditto turned it into more than 7,000 unique assets, each specific to the songwriter, each rendered so it could be shared wherever that songwriter actually lives online. The email carrying those assets hit an 87 percent open rate, and 44 percent of recipients downloaded their asset on day one.
A day-one download rate that high only happens when the thing being downloaded is immediately usable. Songwriters were not saving a file to think about later. They were posting. The formats were already right for the platform they opened next, which is the whole argument in one number. The mechanics, from data upload to render to delivery, are laid out on our how it works page, and pricing starts at $5,000 for 2,500 recipients.
Personalization that only fits one screen is personalization that stops at the inbox. Render every ratio from one row and let your recipients carry the campaign for you. Start a campaign idea at ditto.copilot.app
