Real estate email lives or dies on speed: a listing alert that lands in spam is a lead that went to the agent next door, and a transaction email that bounces is a closing at risk. Most real estate teams send from a CRM or an IDX platform, which means the deliverability problem is usually not their own domain records but the records of the platform they rent.
If your team sends through a CRM, the mail goes out from the CRM's domain, not yours, and the authentication that matters is the CRM's SPF and DKIM, plus the DKIM signature that ties the mail to your brand. Check both: the CRM's sending domain should have a valid SPF record, and your branded mail should carry a DKIM signature that resolves. If the CRM sends from a shared domain you do not control, ask for the sending options that let you use your own domain, and set up SPF, DKIM and DMARC on it.
Buyer alerts go out to a lot of inboxes at once, and a single bad batch can get your sending reputation dinged. Keep the alert list clean: remove addresses that hard-bounced, and give every alert a working unsubscribe. A spike in complaints from stale addresses is the fastest way to get a real estate domain throttled by Gmail and Microsoft, and it takes weeks to recover.
Escrow notices, showing confirmations and closing documents are the mail you cannot afford to lose. Send them from a domain with a clean reputation, authenticate them properly, and monitor bounces. If a closing document lands in spam, the cost is not a missed click, it is a delayed transaction. A daily check of the sending domain is cheap insurance for the highest-stakes mail you send.
Run a free audit on your main domain and on any domain your CRM sends from. Confirm SPF is valid and under the lookup limit, DKIM resolves for the selector in use, and DMARC exists with at least p=none and a reporting address. Fix the two or three things that fail, clean the alert list, and re-check in a week. Most teams see the bounce rate drop within a few days of the list clean alone.
The fastest way to see where you stand is to run the checks now.
