We are a marketing agency of email savants. It comes with the territory of being the agency of record for a company that has superior email capabilities. I can tell you the optimal character count of the subject line on an iOS mobile device (55 characters, thank you very much). Jeannette surpasses Hubspot while coding an email that will render well in notoriously-problematic Outlook. Do not even try to stump Shina on the differences between authentication, identification, and validation because you’ll fail and be shamed.
