Office 365 Setup (no internal branding)


Thanks for using Black Pearl Mail for your new email branding, analytics and signature management. Note that you will need to have Admin access in order to implement the instructions below.

If you do not have Admin access, don't panic, we're always on hand to help you out. Just email us at or click on the orange support button in the bottom left corner of this page.

How it works

The globally distributed Black Pearl Mail technology applies your branding and signatures on outgoing emails. This allows branding to be applied consistently on all emails, even when you send from your mobile phone or tablet. It also lets you manage your branding and signatures centrally in the online dashboard, and generates analytics and reporting on your outgoing email traffic e.g. Sender, Recipient, Subject, Date sent, received and opened.

As your new email branding is applied after the email is sent you should remove your old signature in your email client (desktop, laptop, tablet and/or mobile devices).

We highly respect your privacy and security, and as such do not store the content of your emails.


To have your new email branding applied, follow the instructions below. Remember, we're always on hand if you get stuck or have any feedback on these instructions.

If you have existing connectors, then it's up to you whether you create a new connector or modify an existing one. The process below describes how to route your outbound email via a single connector through the Black Pearl Mail platform. We're happy to discuss what might be the appropriate solution with your environment.
