Want to switch to Cozy. Sending notices to renters advice

[Calvin Thomas]

What we normally do is the property manager receives the payments, and then deposits the rental payments to the associated bank accounts.  However, I want to start streamlining the rental payment process, so I was going to start to use Cozy for some of my properties which are out of my local area (I.E. one's I do not service myself).  Anything an hour away or more, I have a property manager to handle issues with tenants, collect rents as well as it's a requirement for insurance.

Since these are leases I took over from previous landlords after I purchased their properties, I do not have their e-mail addresses to notify the renters that we now accept electronic payments through Cozy.  Any ideas on what I can send them via snail mail?  Cozy requires an e-mail address for the renter, so there is my current roadblock.

Ideas?
