HTML and/or CTA's in Signatures
One of the most effective ways we promote events like our monthly webinar is in the signature of our emails. We use a Wise Stamp to do this.
In HubSpot we have a CTA called Events. Each month, we update the graphic and landing page link on this CTA. Then the new event shows up across our website/blog.
It would be awesome if we could insert either HTML or CTA's in the signature field of HubSpot.
