In our instance, it would be nice to have the ability to add more than 1 signature and then select which signature you would like to use when sending an email in HubSpot. We have a sister company that some employees work for in addition to the parent company - but both companies have their own branding/logo/colors/etc. Our workaround is that we created an email template with the sister company’s branding. So when we respond to an email for the sister company, we use that template so our signature corresponds with the branding.
