If you are really planning growth to scale then mail in house.

Another reason to send it by mail is in many cases you will be deducting damages from deposit.  

Will mail be delivered even if A and B are not officially registered with the USPS?

I ended up changing my RA, and so now they're handling mail.

I'm tired of receiving e-mails from ILUVHOMES@ PROPERTYMAN@ or FASTCASH@ gmail,yahoo, or whatever.

If you only want to mail, you are all set.

LeadSherpa is a good service i had a lot of experience with if you want to go that route.The two best strategies I’ve found are inbound methods: direct mail and Google Ads.Direct mail can be expensive, but it can also yield highly discounted properties.Google Ads, on the other hand, doesn’t require data extraction like calls, direct mail, or texting.

Can someone point me in the right direction when it comes to getting addresses to mail homeowners?

I spent well over 1 mil on a CRM, owned a rock solid direct mail provider and drove a Rolls Royce.
