Campaign banners

A banner is an image injected above or below every rendered signature while its window is open. It needs no template edit, and it removes itself when the window closes.

This is the marketing surface. An event, a campaign, a seasonal message: set the window and forget about it.

Creating a banner

Create a banner in the Banners view. It needs an image, a destination link, a position relative to the signature, and a window.

The image follows the same rules as any signature image: PNG or JPG, no SVG, sized sensibly since it is attached to every message anyone sends while the window is open.

Scheduling

A banner’s start and end are authored as a wall-clock time in an IANA time zone that you choose.

That matters more than it sounds. A campaign can be scheduled for a region other than the one the administrator sits in, and daylight saving is handled correctly: a banner set to end at 23:59 on a date does so at 23:59 local to the chosen zone, whichever side of a clock change that falls on.

The portal shows the window back to you in the zone you chose, rather than converting it to yours.

Opening or closing a window takes effect immediately. The active banner is part of the rendered-signature cache key, so there is nothing to wait for and nothing to purge.

Position

A banner sits either above or below the signature.

Below is the usual choice. It keeps the signature immediately under the message body, where readers expect it, and treats the banner as an appendix. Above works when the campaign is the point and the signature is context.

Click tracking

Banner click-throughs are always tracked. Banner links are routed through tracked links automatically, and there is no opt-out.

Tracking records counts only. No IP address and no recipient identity is logged, so a banner tells you how many people clicked, not who.

Click totals appear in the Link clicks view.

Who can manage banners

The Marketing role reaches campaign banners and link click analytics and nothing else. That is usually the right level for a marketing team: they can run campaigns without being able to change the signature templates or reach billing.

Admins and Editors can also manage banners as part of their wider access.

Practical notes

Keep the file small. A banner is attached to every message sent while the window is open, so a 500KB image is a real cost at organisational volume.

Set an explicit pixel width on the image, and design it to sit comfortably at the width of a signature rather than at the full width of an email client.

Set meaningful alt text. Some recipients will see only that.

Test it before the window opens by setting a short window now, sending a test email, and then setting the real window.

Only one banner window should be open at a time unless you specifically intend otherwise. Overlapping windows make it hard to reason about what any given person receives.

Ending a campaign

Do nothing. The window closes and the banner disappears from every signature at once.

If you need it gone sooner, edit the end of the window to a time in the past, or delete the banner. Both take effect immediately.
