What is Exclaimer?

Exclaimer is a cloud platform for central email signature management. Instead of every employee maintaining their own signature, one set of rules decides what goes under every email. Contact details come straight from your Microsoft 365 directory, so a new job title or phone number shows up without manual work.

Central management

One place to manage signatures for the whole organisation. Different designs per department or team are possible.

Fully automatic

No signature settings on laptops or phones. Signatures are added to outgoing email, whatever device the employee uses.

Always on brand

Logo, colours, contact details and disclaimers are correct on every email. No outdated logos or personal variations.

Campaign space

Use the signature for banners and calls to action: news, events, vacancies or seasonal messages, scheduled in advance.

What it looks like for Raayhof Advisors

Raayhof Advisors is an accountancy firm with 40 employees. Before Exclaimer, every employee set up their own signature. After a rebranding, half the team still used the old logo and the legal disclaimer was missing on mobile.

One professional appearanceClients, partners and authorities see the same signature from every employee.

Disclaimers on every external emailAdded automatically, including on email sent from phones.

No manual changesA new employee or a new phone number is picked up from the directory.

A banner for the year-end deadlineScheduled for November and December, removed automatically afterwards.

Raayhof Advisors is a fictional company used for illustration.

How we work

From first conversation to signatures on every email, usually within a few weeks.

1

Intake and design

We go through your house style, the disclaimers you need and how your teams are organised. Based on that, we design the signatures and agree on any department-specific variants.

2

Connection and rollout

With your approval, we connect Exclaimer to your Microsoft 365 environment and test with a pilot group first. Once everything is correct, we roll out to the whole organisation.

3

Ongoing management

Need a new banner, a changed disclaimer or a design for a new department? Send us a request and we take care of it. No internal IT time needed.

More than email signatures

Exclaimer is often the first step. The same team can take care of the rest of your IT environment.

Frequently asked questions

Do signatures also appear on email sent from a phone?

Yes. Signatures are added after the email leaves the device, so they appear on email sent from Outlook, Outlook on the web and the mobile mail app.

What changes in our Microsoft 365 environment?

Exclaimer reads contact details from your Microsoft 365 directory. To add signatures on every device, outgoing email is routed through Exclaimer by a mail flow connector and rule in Exchange Online. We set this up with your approval during a planned window and document every change. Mailboxes, users and the way your team works stay the same.

Can different departments have different signatures?

Yes. Rules can be based on department, group or individual, so sales, finance or a second brand can each have their own design and banners.

Who makes changes after the rollout?

We do. You send us a request for a new banner, disclaimer or layout change and our team implements and tests it.

How is Exclaimer billed?

Exclaimer is licensed per user. We combine the licences and our management in one monthly invoice.
