Hi Harry,
Do you have sales access within your HubSpot portal? If so, follow the instructions below and this should help fix your issue. If not, feel free to reach back out and I will be more than happy to look into this further.
1) Copy the source code from Email Signature Template Generator
2) Log into your HubSpot portal and click on your profile in the top right
3) Choose Profile and Preferences
4) Scroll down on that page until you see ‘Signature’
5) Click on ‘Edit Signature’
6) Select the HTML option and paste the code in the top box
7) You should then see a preview of your signature below
Click save and send a test email
Please let me know if this did not work for you.
Thanks,
Elysha Shave
