Institutional clustering and .edu concentration
Hobsons' presence clusters in the higher education sector, particularly among mid-sized and smaller universities that use its platform for prospect outreach and enrollment workflows. This .edu concentration means the platform is primarily a factor in institutional email authentication and reputation, rather than a widespread consumer-facing sender; recipients of Hobsons mail typically expect it in educational contexts. From a deliverability perspective, this narrower focus means Hobsons operates in a relatively specialised email ecosystem where institutional authentication practices (SPF, DKIM, DMARC) are the primary deliverability levers.
