Morrow Coffee is an illustrative brand.
Built for teams

Made for how agencies actually ship.

Clients, campaigns, approvals and exports in one place, so nothing lives in a spreadsheet or an inbox.

Every client separate

Each client keeps its own brand kit, products, feeds and campaigns. Nothing leaks from one brand into another.

Roles and review links

Owners, editors and reviewers. Reviewers approve without editing, and clients review in a link without an account.

Checked before delivery

Fit checks catch copy that overflows a size. Approvals lock a version, and any change to its data asks for approval again.

Exports ready for
  • Display & Video 360
  • Adform
  • The Trade Desk
  • AdRoll
  • Standard HTML5
DIY or DFY

Pick the one that fits the job.

Many teams do both: DIY for everyday campaigns, done for you for launches and big feeds.

FAQ

Questions we get asked.

What is DynamicLDN?

A web app for building dynamic HTML5 display ads. You set up a brand once, write a message, pick formats and connect a feed, and DynamicLDN builds every size and every variation, ready to download.

What is the difference between DIY and done for you?

DIY means your team uses the app. Done for you means the TrafficLDN team uses it on your behalf, then QAs and traffics the ads in your ad server or DSP. You can switch between the two campaign by campaign.

Which ad servers and DSPs does it work with?

Exports are packaged for Display & Video 360, Adform, The Trade Desk and AdRoll, plus standard HTML5 with a clickTag for anything else that accepts HTML5 display.

Do we need to give you access to our platforms?

Not for DIY: you download the ads and upload them yourself. For done for you, we work inside your own ad server or DSP account, under your agency's name.

How does the feed work?

Upload a CSV or TSV file, up to 1,000 rows. Map columns such as product name, price, image and landing page to the parts of the ad, and each row becomes its own ad. Missing values fall back to wording you set.

Who owns the ads?

You do. Your brand assets, feeds and finished ads belong to you, and each workspace is private to your team.

Can our clients review the ads?

Yes. Share a review link for a saved version. Clients can see every size and variation without an account, and you can revoke the link at any time.
