Yes, it is common for real estate professionals to use a combination of direct mail and Facebook advertising campaigns. Direct mail allows you to target specific homes and homeowners, while Facebook ads allow for retargeting and reaching a larger audience through social media. By using both methods together, you can increase your chances of reaching and engaging potential buyers or sellers. However, it's important to be aware of the possibility of oversaturating your audience with too many ads. It would be best to consider the audience's attention, and how to distribute your message accordingly.
