Remove Me From Your List?

[Thomas Garza]

I have started a small direct mail campaign targeting landlords who have recently filed an eviction. Luckily, I am easily able to get the owners name and address, and often times, their phone number and email address. 

My plan was to send out the first letter, wait 2 weeks, and then send out another letter followed up shortly by a text message (I am currently at this point). After that, I would send them one more letter 3 weeks later, followed up shortly by an email. 

My question is, when do I take someone off of my list? If someone tells me that they are not interested in selling their house, should I take them off my list? What about if they specifically ask to be removed from my list? 

My current thought is that I would keep sending them letters regardless of what they ask, in case they change their mind, but if they specifically ask me not to text or email them again, I would comply with their request. What are your thoughts?
