What to consider when planning campaign banners in signatures

Signature banners can turn every email into a lightweight marketing placement, but unstructured usage makes performance harder to measure.

Start with a clear campaign window. Without defined start and end dates, outdated banners remain in circulation for too long.

It is usually better to focus on one message instead of several offers at once. This keeps attention on a single CTA and simplifies reporting.

Use UTM-tagged links and clear CTA copy to understand campaign outcomes. This makes it easier to compare conversions across sends.

When a campaign ends, remove or replace the banner quickly. Expired promotions weaken trust and reduce overall brand quality.
