Email is the lifeblood of corporate communication and the gateway to any business, but securing it doesn't need to be a difficult task for your IT team. Office 365 uses the latest technologies to keep email data private and protected from ever-evolving threats while staying mobile and accessible from the desktop or anywhere. Because these security features are built-in and automatically updated, your business security requires minimal involvement from your IT team.

When it comes to email signatures in Office 365, it's a good idea to have different variants on hand for different purposes. It is common practice to set up two signatures for the same sender: one with full contact details and graphics while other with information limited to the bare essentials. The first signature is only applicable when you send an email to an external user, while the second appears to the internal users. This means that the email signature remains legible, and the most important information is always at hand.

  • Native Office 365 email signature will not override the existing email signatures with the disclaimer rule.

  • If some users don't want certain information to be displayed in the signature, you can't exclude the variable properties for users.
  • Will add the Signature only at the end of the email. Due to this, in the case of forward/reply messages, signatures will be piled one after the other at the end of an email.
  • If the AD fields are empty, fetched from the active directory, the signature will have whitespace in front of the particular field and won't be removed.
  • Recipients receive images as attachments as they can't embed them.
  • Only admins can manage the email signatures of Microsoft 365 users.
  • Signatures won't be visible in their email client before sending an email.

Advantages of Sigsync Email Signature

It's easy to believe that an email signature is just a fancy design that has your name and photo embedded in it. It's a lot more than that. This is a useful marketing tactic that can be useful for your business. This way, you can stamp your branding without the hassle.

Since you've embedded all of the company information like name, logo, contact, and colors in the signature, recipients can easily identify your brand. In the age of artificial intelligence, a picture of yourself in the email signature signals to your readers that you are a real person behind the desk and not a robot. A "signature" is indispensable when composing a business email. Once set, it's an excellent item that can be used forever unless there is a change.

We all have a signature in our email with personal, company contact details, and maybe even some advertising flash. In a teamwork and multi-device environment, setting up this email signature can be an ordeal. Go user by user, application by application, device to device to configure the signature ... That everyone has the same to give a good corporate image is basic. Ask your marketing or business strategy department what they think that each one has a different company signature or how to take advantage of this space to offer better customer service or else. It is a space for our brand.
