Best way to collect updated emails from RE clients?

[Lauren Munar]

Hello RE Pros,

I recently made the industry switch from tech to real estate so I could learn more about the biz from the inside. I am assisting two top agents in ATL and we're working on a campaign to update our email lists with email address updates. 

What is the best way to collect updated emails from past clients, while incentivizing them by adding value?

I've done a little research online and the following ideas seem to be the most viable. 

• Create a survey gathering insights or votes for real estate-related subjects
• Free e-book (i.e. Top 5 Housing Trends in ATL that Every Seller Needs to Know)

Any additional ideas insights appreciated!
