Education email has a failure pattern no other industry has: the list changes every semester. A university sends to thousands of new students whose addresses have never received mail from the domain, and to alumni whose addresses go stale within a year. The domain records matter, but the list lifecycle is where most of the damage happens.
When a domain sends to a fresh batch of addresses, receivers have no history for the sender, and the first wave of mail gets extra scrutiny. Warm the domain before the semester: start with the smallest, most engaged segment (current students, then faculty, then prospective students) and ramp volume over a few weeks. A domain that sends 50,000 welcome emails on day one of orientation is asking for a spam-folder week.
Same four as every other industry, with one education-specific twist. SPF: list every service that sends for the institution, which is usually more than a team expects: the LMS, the billing system, the career portal, the alumni platform, and the email marketing tool. DKIM: a key per service, with the selectors documented, because university IT changes vendors every few years and the old keys quietly stop matching. DMARC: start at p=none with reporting, because the aggregate reports will show you every department and vendor sending as the domain, including the ones nobody remembers approving. MX: confirm the mail exchangers for the main domain and the department subdomains that receive mail.
Alumni mail is where bounce rates live. An address that has been dead for two years still counts against your domain the moment you send to it. Clean the alumni list before every major send: remove hard bounces, suppress addresses older than a set threshold that have not opened, and keep the donation asks on the cleanest segment you have. A 2% bounce rate on an alumni blast is enough to get the whole domain throttled, and the students' enrollment emails go with it.
Universities run dozens of subdomains, and each one that sends mail needs its own SPF and DKIM unless it inherits from the parent. Run a free audit on the main domain and on the subdomains that send, and put the ones that send on a daily check. The subdomain that breaks is usually the one nobody is watching.
The fastest way to see where you stand is to run the checks now.
