Real estate emails that reach the inbox.

• 01

  New agent domains land in spam for the first 4–6 weeks. Most new agents set up a personal domain and start sending listing announcements immediately. Without warmup, those emails land in spam and the agent never knows. By the time they check, the domain is burned.

• 02

  Spam complaints spike silently when reply rates drop — by the time you notice, the domain is burned. A sudden drop in reply rates often signals deliverability problems, but most agents don't monitor this closely. By the time the issue is visible, the domain needs weeks of recovery.

• 03

  Multiple agents sharing one domain kills deliverability for the whole team. When 5 agents send from the same domain, the combined volume triggers spam filters. One bad campaign from one agent damages reputation for everyone.

• 04

  There is no visibility into inbox placement across Gmail, Outlook and corporate filters. Your emails might land in the inbox at Gmail but go to spam at Outlook. Without cross-provider testing, you're optimizing for one inbox while ignoring the rest.

• 05

  Most warmup tools cap volume and lack reputation monitoring. Most free tools warm up 50-100 emails per day and provide no visibility into inbox placement. You're warming up blind, hoping it works, and discovering the damage only after a campaign fails.
