Processes for managing mailing campaigns

[Brandon Rush]

Hey everyone. What are some processes you have for tracking who you are sending your mailing campaigns out to and regularly updating the status for each of them?

I have done a few mailing campaigns but trying to keep track of who I mailed to and how many times. I am also looking to document bad leads and sellers who ask me not to reach out to them anymore. I am working off of a Google sheet but it can get a bit crazy to manage when mailing a few hundred property owners.

Any suggestions? As always, thank you.
