Short answer: a good open house email has a specific subject line (address or standout feature plus date), the date, time and address in the first two lines, three to five verified highlights, a photo, one clear call to action (RSVP, add to calendar or reply) and your contact details. Send it 5-7 days before, with a reminder the day before.

Common mistakes
- Burying the date and time below the fold
- Generic subjects like "Open House!"
- Phrases like "perfect for your growing family" (check with the Fair Housing checker)
- Emailing people who never opted in. Follow CAN-SPAM: honest subject lines, your physical address and an unsubscribe option for marketing emails.
