I am familiar with the (dis) benefits of Inbound Sales. However, I concept maybe there is already a few research about how often Inbound Sales is used in distinct Industries, or sorts of enterprise with some resource links.
Same issue here. I have a mobile ready validated email and have checked this in mailchimp and putmsail and works perfect. Hubspot does not render this and they told me to look in the forums so they don't really care about my question or solving it.
