Yes. To run a Facebook ads campaign alongside a direct mail campaign for real estate, you can follow these steps:

Define your target audience: Identify the demographics, interests, and behaviors of the people who are most likely to be interested in buying or renting a property.

Create a Facebook ad campaign: Use the Facebook Ads Manager to create a new campaign and select the objective that aligns with your business goals (e.g., "Lead Generation" or "Conversions"). Then, choose the target audience you defined earlier and create ad creatives that align with your direct mail campaign.

Set up your direct mail campaign: Create a direct mail piece (e.g. brochure, postcard, letter) that aligns with your Facebook ad campaign and target audience, and create a list of mailing addresses of potential customers who match the target audience.

Track and measure the results: Use Facebook's conversion tracking and conversion pixels to track the results of your Facebook ad campaign. Also track the conversion rate of direct mail. Compare the performance of both campaigns and try to understand which medium is most effective for your target audience.

Optimize and adjust: Use the data you collect to optimize and adjust your campaigns for better performance. Use the most successful ad or direct mail creatives and discard underperforming ones.

It's also good idea to consider integrating your campaigns by having a consistent message on both ads and direct mail, and a unique tracking link or coupon code for each medium to properly attribute leads.
