Avoid Spam Filters: Use a Whitelisted Number from Espresso Agent

If Your Calls Aren’t Getting Through, You’re Losing Listings

Are your cold calls going straight to voicemail? Are prospects telling you your number showed up as “Spam Likely?” You’re not alone. At Espresso Agent, we help real estate agents like you whitelist your number to avoid being incorrectly impacted by spam filters and increase answer rates fast.

What Is Whitelisting?

Whitelisting is the process of registering your business number with major phone carriers to prevent your calls from being incorrectly marked as spam or scam likely. When your number is whitelisted, it signals that you're a legitimate caller — not a robocall or scammer.

What Happens If You Don’t Whitelist?

Not whitelisting your number can cost you listings and commissions.

Calls flagged as spam or blocked
Prospects don’t answer unknown or sketchy numbers
Lost trust and missed opportunities
Lower ROI on your lead generation

Why Are Your Real Estate Calls Marked as Spam?

Carriers use analytics and complaint data to flag numbers that:

Make high volumes of outbound calls
Call people who don’t answer or block the number
Use generic caller IDs or spoofing behavior

Real estate agents cold calling expireds, FSBOs, or neighborhoods are often caught in these filters — even if you're doing everything right.
