Ringless voicemail prospecting: is it legal, and what does it cost?

Ringless voicemail and the law

Ringless voicemail is legal only with consent. The FCC ruled that a ringless voicemail delivered to a wireless number is a "call" made with a prerecorded voice. That puts it under the same consent rule as a robocall. A marketing drop needs prior express written consent.

The ruling is FCC 22-85, adopted 11/14/2022 and released 11/21/2022. It answered a petition from a ringless voicemail company that argued its drops were not calls. The FCC denied that position and found that ringless voicemail to wireless phones "is a 'call' made using an artificial or prerecorded voice." The ruling was published in the Federal Register on 12/14/2022 and took effect on 11/21/2022. Since the Supreme Court decided McLaughlin Chiropractic v. McKesson on 06/20/2025, courts are not bound by an FCC reading of the TCPA and decide the meaning themselves. Do not plan around that: courts treated drops as calls before the FCC ruled.

The statute behind it is 47 U.S.C. 227(b)(1)(A)(iii), which bars prerecorded-voice calls to cellular numbers without prior express consent. The FCC's rule at 47 CFR 64.1200(a)(2) raises that to prior express written consent for telemarketing and advertising. Written consent means a signed agreement, electronic signatures allowed, that names the seller, lists the number, and says signing is not a condition of purchase. See the TCPA explained and the ringless voicemail rules for the full text.

Cold list or consented list

Ringless voicemail is a consented-list channel. It is not a cold-list channel. A purchased list of owners with phone numbers does not carry consent to receive your prerecorded messages. A cold calling program can use a human dialing a scrubbed list. A drop cannot.

Audience	Consent status	Drop allowed?
Web form lead who ticked a written-consent box naming you	Written consent on file	Yes, within the scope of the consent
Past client who signed a marketing consent	Written consent on file	Yes
Past client with only a transaction record	No written consent	No for marketing
Purchased owner list, wireless numbers	None	No
B2B landline, business number	No wireless rule applies	Check Do Not Call and state law first

The FCC ruling covers wireless numbers. For residential landlines, 47 U.S.C. 227(b)(1)(B) separately bars prerecorded messages without consent. Commercial business landlines are less clear, and state laws add their own limits. Get a lawyer's read before you build a program on that gap.

Where it still fits

Use it as the second or third touch after a person has already raised a hand.

1. Follow-up to inbound leads. The person filled out a form with a consent line. A short drop that says who you are and what they asked about lands after the first call goes unanswered.
2. Existing customers with written consent. Reminders, open house notices and listing updates to people who opted in.
3. Appointment reminders tied to a request the person made.

For most cold outreach, the better options are direct mail, which needs no consent, and manual calling to a scrubbed list. For consented texting, see SMS prospecting. To size a mailing universe, use the homeowner counts.

What a ringless voicemail drop costs

Platforms publish low per-drop rates. These are published ranges from one provider's pages and will change, so check them before budgeting. Rates below are from the provider's own pricing and FAQ pages, not independent audits.

Item	Published figure	Source
Per drop, bring your own carrier	From $0.006, no monthly fee	Provider FAQ
Compliance fee	$0.0039 per message	Provider pricing page
Messaging plan with included drops	From $125 a month	Provider pricing page and FAQ
Messaging plus dialer plan, one power dialer seat	From $224 a month	Provider pricing page

Worked example for a consented list of 1,000 people on the bring-your-own-carrier option, assuming the per-message compliance fee applies to those drops (the pricing page does not say it is waived):

• Drops: 1,000 x $0.006 = $6.00
• Compliance fee: 1,000 x $0.0039 = $3.90
• Total platform cost: $9.90, or $0.0099 per drop
• Your own carrier charges are extra and not included.

The cost is small. The cost of one unconsented drop is not, as the penalty section shows.

What results vendors report

Callback rates are vendor-reported, and no independent benchmark exists. One provider's blog says "many businesses see 1-5% callback rates from delivered messages." The post cites no study and says rates vary by industry, list quality and message relevance.

Metric	Band	Label
Callbacks per delivered drop	1% to 5%	Vendor-reported, provider blog 01/06/2026

Using that band on the 1,000-drop example, and assuming every drop delivers, you get 10 to 50 callbacks. Divide $9.90 by those and the platform cost is $0.20 to $0.99 per callback. Carrier fees, list cost and your time sit on top.

Track these five on your own list instead of trusting a band:

Number	How to calculate	What good looks like
Delivery rate	Delivered / sent	Your own baseline; investigate any drop-off
Callback rate	Callbacks / delivered	Compare to the 1% to 5% vendor band, then to your own history
Appointment rate	Appointments / callbacks	Set from your first three sends
Opt-out rate	Opt-outs / delivered	Falling over time; a rise means the message or list is off
Cost per appointment	All costs / appointments	Below your cost per appointment from other channels

A consented sequence

This rail assumes every contact signed written consent that names ringless voicemail or prerecorded messages.

• Day 0Lead submits a form with a consent line. A person calls within five minutes.
• Day 1No answer: one drop, 20 seconds, name, reason, one callback number.
• Day 3Text with the same ask, using the consent already on file.
• Day 7Second drop. Offer a specific next step, such as a time slot.
• Day 14Mailed postcard. No consent needed.
• Day 30Stop. Move the record to a slow mail cadence.

Every drop gives a way to opt out and the opt-out is honored at once. For a wider plan across channels, see the multi-channel sequence. The hub for other methods is How-to guides.

Compliance notes and penalty exposure

A private plaintiff can sue under 47 U.S.C. 227(b)(3) for actual loss or $500 per violation, whichever is greater. A court can raise that to three times the amount, so up to $1,500, if the violation was willful or knowing. Each message is a violation.

Unconsented drops	At $500	At $1,500
100	$50,000	$150,000
1,000	$500,000	$1,500,000

Those figures are statutory arithmetic, not predictions of a verdict. They show why a $9.90 send can create a claim of $500,000 to $1.5 million.

Working rules:

• Keep the signed consent record, timestamp and wording for every number, and keep it after the campaign ends.
• Match the drop to the scope of the consent. Consent to a callback about a listing does not cover unrelated marketing.
• Do not buy consent claims from list sellers. The seller named in the agreement must be you.
• Respect the national and state Do Not Call lists on top of consent.
• State laws can be stricter than the federal floor. Read the state-by-state rules before you launch.

This is general information and not legal advice. Have counsel review your consent form.

Next step

If you plan to pair consented voicemail with mail, start from the owner universe you can reach by address. Get counts for your zip codes before you buy a list.

Questions people ask

Q01Is ringless voicemail legal for real estate prospecting?

Yes, if the recipient gave prior express written consent to receive marketing voicemails at that number. Without consent, a marketing drop to a wireless number is a TCPA violation, whatever your license or industry. Cold lists do not qualify.

Q02Does ringless voicemail avoid the Do Not Call list?

No. The FCC ruled the drop is a call, so it is treated like any other prerecorded call. A Do Not Call scrub alone does not make a marketing drop legal, because prior express written consent is still required for each number.

Q03Can I send ringless voicemail to landlines?

The FCC ruling addressed wireless numbers only. For residential landlines, the statute separately bars prerecorded messages without consent, with narrow exemptions. Treat landline drops the same as wireless unless counsel tells you otherwise.

Q04How much does a ringless voicemail drop cost?

One provider publishes a bring-your-own-carrier rate from $0.006 per drop and a $0.0039 per message compliance fee. Plans with included drops from the same provider start at $125 a month. Check current pages before budgeting.

Q05What callback rate should I expect?

One provider blog says many businesses see 1% to 5% callbacks from delivered messages. That is a vendor claim with no published method. Measure your own consented list over several sends before you trust any benchmark.
