We help brands and businesses add great endings to every email conversation

We’re re-inventing the email signature

When we think of great customer experiences, attention always jumps to first impressions. ​But in a world of ‘hello’, we don’t want to miss the impact of a great ‘goodbye’.

After all, it’s endings that make the real difference. It’s endings that we remember.

Email signatures are the underdog, the unsung hero of emails. The simple feature we expect to be there, providing the relevant contact information. But at Exclaimer we see email signatures as so much more than a simple sign off. It’s an opportunity to present a consistent brand identity and supercharge those valuable, personal interactions between your company and your audiences, with endings that:

Promote marketing campaigns

Collect real-time customer feedback

Share your latest news or events

Comply with email legislation
