I just got a call tonight that from someone that I mailed to and he said " I got you letter a couple of months ago and now I am ready to sell a few houses." so if the phone doesn't ring right away don't it.

=)Last thing - don't just mail a few letters and then sit back and wait for the phone to ring.  

I use Vumber though i just let it go straight to the voicemail without it ringing but it has done great so far.

RVMs don't really work (doesn't leave vm, or it doesn't ring through, or there's a long delay in the voicemail before recording starts), and some of my automated SMS simply isn't going out despite being scheduled.

The Ringless Voicemail Drop is compliant because: No phone call is ever made directly to the targeted subscriber.Only a landline to landline session, aka system to voicemail server, is established to drop the message.The targeted subscriber is not billed for the call.The phone does not ring and the network does not carry an active call.The FCC defines voicemail services as an Enhanced Information ServiceThe FCC has intentionally not regulated Enhanced Information Services.If you have any questions please don't hesitate to reach out to me.

Some other pros of text message marketing is that you can send a text much more quickly than waiting for the phone to ring.

Phone starts ringing with potential sellers.

When I see a VM pop up on my phone when there was either no ring or 1 ring, I instantly delete the VM and block the number and send it to the Hiya app so it gets flagged as a spam number.I cannot tell you how much it ticks me off - and that's the reason I refuse to even consider it.

@Tony Johnson You can't go wrong with Account Closed Work with them directly and your phone will never stop ringing.
