In short
Clients and projects organize what you have already made. Templates are for making the next thing faster. They look like three flavours of the same feature and they are not.
Two things on this page will save you real pain: a template is a live pointer to an existing Mark rather than a saved copy of its settings, and reset is destructive in a way that delete is not.

How the three fit together
Clients and projects form a two-level hierarchy over your items. Templates sit outside that hierarchy entirely — they are shortcuts for creating things, not containers for holding them.
Clients
A client is the top level: the organization or person the work belongs to. Agencies use them per customer; in-house teams often use them per brand, per region, or per department.
A client is worth creating even if you only have one, because it is what makes reporting separable later. Items can also sit outside any client — the console calls this unassigned or non-client — which is fine for personal work and a nuisance at scale.
Projects
A project is the second level, and it normally belongs to a client. The console asks you to pick or create the client first, and following that is what keeps the hierarchy meaningful. A project can end up without one all the same — deleting a client leaves its projects in place and simply un-assigns them — so treat client-first as the habit to keep rather than a rule the platform will enforce for you.
Think of a project as a campaign, an event, a print run, or a season — something with a beginning and an end. "Autumn catalog", "Trade show Hall 2", "Q3 packaging". Not "Marks" or "Stuff", which describe the container rather than the work.
Templates are pointers, not snapshots
You create a template by opening a Mark you have already configured well and choosing Save as Template. You give it a name, and it appears in your template list with a link to view the original.
That link is the clue. The template stores a reference to that Mark — not a frozen copy of its settings. Everything follows from this:
| If you… | Then… |
|---|---|
| Edit the original Mark's settings | The template now produces the new settings. Sometimes exactly what you want; sometimes a surprise months later |
| Delete the original Mark | The template has nothing to copy from and stops being usable |
| Transfer the original Mark to somebody else | Same problem — it is no longer yours to read settings from |
| Want a genuinely frozen configuration | Keep a dedicated Mark that exists only to be a template, and never repurpose it |
What applying a template copies
Applying a template is not all-or-nothing. You are offered a checklist and you tick the groups you want carried over, which makes one well-configured reference Mark usable for several different purposes.
| Group | What comes across | Usually worth ticking? |
|---|---|---|
| Destination and rotation | The address list and the rotation mode | Rarely — the new item normally has its own destination |
| Password | The password protection setting | Yes, when the whole set should be protected the same way |
| Secure | The invited-access flag | Yes for confidential sets. Remember the invite list is per item |
| Geo targeting | Location routing rules | Yes — these are tedious to rebuild by hand |
| Device targeting | Device and platform routing rules | Yes, same reason |
| Client and project | The assignment | Yes when the new item belongs to the same work |
| Tracking pixels | Configured pixels | Yes for anything in the same campaign |
| Parameters | The parameter builder set-up | Yes, then adjust the campaign name |
| Expiration | The expiry date | Only if the dates genuinely match — check this one |
| Start and stop | The active window | Same caution as expiry |
| Scan limit | The interaction cap | Only for identically-scoped items |
| Webhook | The notification or webhook setting | Yes for anything feeding the same system |
The two to look at twice are expiry and start/stop. Copying a date from a reference Mark built last spring is how a brand-new item arrives already expired, and the symptom — content that will not open, with no obvious cause — takes a while to trace back to the template.
Delete versus reset
These sit next to each other in the console and their consequences are not comparable. Read the table before using either on a client or project with real history under it.
| Action | What happens to the items | What happens to the history | Reversible? |
|---|---|---|---|
| Delete a project | They survive, un-assigned from that project | Untouched | Effectively yes — reassign them |
| Delete a client | They survive, un-assigned from that client | Untouched | Effectively yes — reassign them |
| Reset a project | They survive, still assigned | Deleted, for every item in the project | No |
| Reset a client | They survive, still assigned | Deleted, for every item under every project | No |
Deleting is the gentler choice precisely because it only removes the label. If you are unsure which you want, you almost certainly want delete.
Setting this up so it stays useful
- Create the client before the first item.Even for your own work. It costs one field and makes everything after it separable.
- Name projects after the work, not the container."Spring launch — Hall 2 signage" reads correctly in a report next year. "Marks 2" does not.
- Build reference Marks for templates, deliberately.Prefixed names, holding-page destinations, never repurposed. This is the single habit that makes templates trustworthy.
- Assign on the way in, on every creation path.Including bulk runs, where the cost of not doing it multiplies by the run size.
- Review the checklist each time you apply a template.Especially the date fields. Ticking everything by reflex is how expired items get created.
- Export before any reset.Treat reset as a data-destruction operation, because that is what it is.
Symptoms, causes and fixes
| Symptom | Cause | Fix |
|---|---|---|
| A template produces settings you did not configure | Somebody edited the Mark it points at | Use the view-original link to see the current source; move to a dedicated reference Mark |
| A template stopped working | The Mark it pointed at was deleted or transferred away | Rebuild the template from a Mark you control and will not repurpose |
| Cannot create a project | No client selected — a project must belong to one | Create or pick the client first |
| A newly created item is already expired | Expiry was copied from a template built earlier | Clear the date; untick expiry and start/stop when applying templates |
| Items vanished from a client view | The client or project was deleted, which un-assigns rather than deletes | Find them in the unassigned list and reassign |
| All interaction history for a client is gone | Reset was used at client level | Not recoverable. Restore from an export if you made one |
| Reporting cannot separate two campaigns | Both were created unassigned or under one project | Assign future items properly; past interactions cannot be split retrospectively |
