Marketing emails are all emails dispatched as a result of a campaign or automated workflow. These may be the result of a marketing campaign dispatched to several thousands of people or the emails that result from particular workflows.
FULL FABRIC uses SendGrid as the SMTP gateway for all marketing emails. All marketing emails originate from one of several fullfabric.com subdomains dedicated to marketing emails.
While we plan to support other gateways down the line, this is currently the only option. No set up is required.
