How Can We Help?
Short answer: Exclaimer is a cloud service that applies one consistent, professionally designed email signature to every message your staff send, on any device. You design it once, it updates itself from your Microsoft 365 user directory, and nobody has to copy and paste HTML again.

Why central signatures matter
| Problem with DIY signatures | What Exclaimer does |
|---|---|
| Every person has a different layout, font and logo | One approved template for everyone, or one per team |
| Phone and tablet emails go out with no signature | Signature is added to mobile and webmail messages too |
| Staff change job titles and numbers, signatures go stale | Details pull from Microsoft 365 so they stay current |
| Legal wording is forgotten or inconsistent | Disclaimers and regulatory details applied automatically |
| Marketing cannot promote anything in everyday email | Banners can be scheduled by team, with click reporting |
Server-side or Outlook add-in
| Method | How it works | Best for |
|---|---|---|
| Server-side (Exchange Online) | Signature is added after the email is sent, so it appears on every device | Making sure no message ever goes without one |
| Outlook add-in | Signature appears while the user writes, and they can pick from the options assigned to them | Teams that want to see and choose their signature |
| Both together | Add-in for convenience, server-side as a safety net | Most business set-ups |
