Any automatic email notification sent by JobMount job board software includes configurable header and signature:
Settings: Email notifications: Email header Settings: Email notifications: Email signature
Important: the header & signature will be automatically added to ALL the email notifications you have in place. If you want to have a custom header and/or signature for each separate email notification – don’t use these nodes, but instead, go to Email templates and add a unique header and/or signature to each individual email template (more info here)

Notes
- Add links or images using absolute URLs, i.e. https://www.your_domain.com/imglib/logo.jpg
- Try to use as less links as possible
- Avoid using MS Word formatted HTML and use as simple code as possible, see more
- Changes to these nodes take effect within 24 hours.
- Email header and footer are common WYSIWYG fields.
- You can place images that will be downloaded from your website when recipient reviews the email text.
