Email Signature Manager #
Standardizing corporate branding across a growing organization is a constant challenge, especially when employees edit, break, or remove their required email signatures.
Email Signature Manager solves this by letting Google Workspace administrators design, assign, and automatically enforce standardized HTML signatures across individual users, groups, or Organizational Units.
Once assigned, signatures are updated daily and automatically corrected if modified by the user, ensuring complete brand consistency without manual intervention.

Frequently Asked Questions #
1. I saw the Email Signature Manager appear on my domain. Do I have to pay extra for that?
No, it has been released as a free tool for all administrators with the Essential Plus plan and upward. If you see it on your domain, you do not have to pay extra.
2. Can I apply a different email signature to different Google Workspace users?
Yes. Email Signature Manager allows administrators to apply email signatures to individual users, groups, or Organizational Units (OUs).
3. Can I create custom HTML email signatures?
Yes. You can create a custom HTML email signature using the HTML editor or choose from our predefined templates.
4. Can I preview an email signature before deploying it?
Yes. The ‘Show preview’ option lets you preview how the email signature will appear for a selected user before applying it.
5. Can I assign different email signatures to different users or departments?
Yes. Email signatures can be assigned to users, groups, or Organizational Units. If a user matches multiple assignments, the assignment with the highest priority is applied.
6. Are email signatures applied automatically?
Yes. By default, Email Signature Manager automatically applies signature assignments daily to the selected users.
7. At what time of day does the signature get assigned?
It will run roughly every 24 hours and is dependent on the time of the GAT+ scan that has run within the same time period, so it will differ slightly each time.
8. Where is the signature image saved?
It’s saved in your organization’s shared drive. The admin who first sets the signature will become the shared drive manager. This shared drive will be created automatically and will be public by default.
9. What if the admin leaves the organisation; will that break the signature?
No, the signature is stored in the organisation’s shared drive and made public for robustness.
10. What type of images are supported?
JPEG, JPG, PNG, and GIF image files are all supported.
11. I use a different signature manager tool; can I transfer my signature from there?
Yes, just paste the HTML from your previous signature into the HTML window in the Email signature manager when creating the template. Watch out for variables in the signature; your previous signature tool may use a different placeholder variable to display attributes on the user’s profile. Ask the GAT Assistant for help replacing the variables so that they will work with the Email Signature Manager, and it will fix that for you in a few seconds
12. I have some custom attributes on my users’ accounts; is there a way I can get a dynamic variable for those
Yes, you will see the variable for any custom attributes you have in Google Workspace readily available in the ‘Template variables’ dropdown window; just select the Custom Attribute section on the left-hand side.
13. I want my variable to be uppercase; is there a way to configure that?
Yes, the Liquid Templating language can be used to cover this case. Use {{ name | upcase }} to display the full name in all capitals, for example.
14. What happens if I add a variable to the signature and a user doesn’t have that attribute? Will that break the signature?
No, the attribute will simply be left blank on the user’s signature.
15. Can I omit a whole chunk of the signature if the user doesn’t have an attribute?
Yes, you can omit the whole line about their work phone number if they don’t have a work phone, using {% if workPhone %} Work Phone: {{ workPhone }} {% endif %}
16. Is there a limit to the number of signatures I can store and use?
No, you can store and use as many templates as you like.
17. Is there any way to outright stop my users from modifying their signature in Gmail?
Yes, GAT Shield can handle this case. You can find out how to do it here.
