Slybroadcast Pricing per Voicemail and Monthly Plan Cost

How much does Slybroadcast cost?

Slybroadcast costs 12 cents per delivered voicemail at the smallest pay as you go block and 3.85 cents at the largest monthly plan. Both ladders sit in the pricing section of the slybroadcast.com homepage (there is no separate pricing page), and we read them on October 8, 2026.

Pay as you go: 100 delivered voicemails for $12, 250 for $24, 500 for $45, 1,000 for $70, 5,000 for $250 and 10,000 for $450. That is $0.120, $0.096, $0.090, $0.070, $0.050 and $0.045 per delivery.

Monthly delivery plans: 100 for $8, 300 for $25, 2,000 for $100, 6,000 for $250 and 13,000 for $500 a month. That is $0.080, $0.083, $0.050, $0.042 and $0.038 per delivery.

Every plan on both ladders lists the same inclusions: unlimited campaigns, unlimited call lists, unlimited audio recordings, the Zapier integration with CRMs, API access, and phone and email support. Senders who need more than 13,000 a month or want to be invoiced are told to contact sales.

• Pay as you go from $12 for 100 to $450 for 10,000 delivered voicemails
• Monthly from $8 for 100 to $500 for 13,000 delivered voicemails
• API access and Zapier on every plan, no feature tiers
• Billing counts delivered voicemails only, per its own pricing header

Is the Slybroadcast monthly plan cheaper than pay as you go?

Per voicemail, yes, but only if you use every delivery in the month. The footnote under the monthly ladder reads, word for word, "Monthly Delivery Plans auto-renew and deliveries do not roll over." Pay as you go credits carry no such warning on the page.

That makes the choice a question of how steady your volume is. A team that sends 2,000 drops every month pays $100 on the monthly plan against $140 for two 1,000 pay as you go blocks. A team that sends 2,000 one month and 300 the next pays $200 across the two months on the monthly plan and $176 on pay as you go ($140 plus a $24 and a $12 block), and the monthly plan loses.

One oddity on the monthly ladder is worth knowing before you pick a tier. The 300 plan costs $25, which is $0.083 per voicemail, more per delivery than the $8 plan for 100 at $0.080. Three $8 plans are not on offer, so a sender at 300 a month simply pays a little more per unit than one at 100.

• Monthly plans win only when you send the full allowance every month
• Unused monthly deliveries are lost at renewal
• The 300 plan costs more per voicemail than the 100 plan
• Above 13,000 a month the price is quoted by sales

What does Slybroadcast include beyond the voicemail drop?

More than the price ladder suggests. Slybroadcast lists AI voice cloning under the name Voicemail Personalization, which inserts the recipient's first name in your own voice or a text to speech voice. It sells a Callback Number that turns on callback reporting and call forwarding, and Follow-up Texting, an automated text sent right after the voicemail lands, requires that Callback Number.

Integrations listed on the homepage are Zapier, Make, Salesforce and Integrately, plus an API that Slybroadcast says is free with each account. It reaches mobiles and select landlines and VoIP phones in the United States and Canada, has a mobile app, and states that it is SOC 2 and PCI compliant. It also offers a refund if you are not satisfied with your first campaign.

What the pricing section does not print is the price of the Callback Number or of follow-up texting. If callback tracking matters to you, and it should if you want to measure anything, ask for that figure before you compare totals.

• Voicemail Personalization with AI voice cloning
• Callback Number for reporting and forwarding, price not printed in the pricing section
• Follow-up Texting, which requires a Callback Number
• Zapier, Make, Salesforce and Integrately, plus a free API

Slybroadcast vs Drop Cowboy, LeadsRain and other ringless voicemail vendors

Slybroadcast is in the middle of the category on price and at the simple end on billing. Our own arithmetic on each vendor's published rates puts 10,000 voicemails in one month at about $200 on LeadsRain, $250 on Drop Cowboy, $350 on Drop.co, $450 on Slybroadcast pay as you go, $495 on VoiceDrop.ai and about $650 on Call Loop. The table above shows the inputs and the date each was read.

The unit is the catch. Slybroadcast and Call Loop bill per delivered voicemail. LeadsRain, Drop.co, Drop Cowboy and VoiceDrop bill per attempt, so a 2 cent attempt that delivers 70 percent of the time is really 2.9 cents per delivery. Ask every vendor for the delivery rate it sees on lists like yours, then divide.

One ranking result for this query is a competitor's blog quoting Slybroadcast at $10 for 100, $40 for 500 and $400 for 10,000. Those are not the figures on slybroadcast.com today, which shows $12, $45 and $450. For the real estate side of the comparison, including Slybroadcast against Drop Cowboy on a 10,000 drop month, see our guide to the best ringless voicemail service for real estate investors, and the category overview on ringless voicemail service pricing. Drop Cowboy renamed its plans and trimmed every allowance in October 2026, and it now sells dialer seats too, which we break down in Drop Cowboy pricing.

• Per delivery vendors: Slybroadcast, Call Loop
• Per attempt vendors: LeadsRain, Drop.co, Drop Cowboy, VoiceDrop.ai
• Only LeadsRain prints a DNC scrub price, $0.002 a number
• Third party price quotes for Slybroadcast are often out of date

Is Slybroadcast legal for cold outreach?

Slybroadcast's own FAQ says ringless voicemail is "legal but regulated like any other telecom service". That is accurate and leaves out the part that matters for a cold list. In Declaratory Ruling FCC 22-85, released November 21, 2022, the FCC held that a ringless voicemail to a wireless number is a call made with an artificial or prerecorded voice, so it needs the consumer's prior express consent under the TCPA, and written consent if it is marketing.

The arithmetic is what should decide the plan you buy. The TCPA sets statutory damages at $500 per call and up to $1,500 if the violation is willful. Ten thousand drops to a skip traced list of cell phones cost $450 to send and carry a theoretical $5 million of exposure at the minimum rate. The voicemail is cheap and the list is the risk.

The same rule applies to any artificial voice, including AI voice agents, so this is not an argument for one channel over another. It is an argument for sending only to contacts who consented, scrubbing the DNC list before every campaign, and keeping the record. If you work in real estate, our page on auto dialer for real estate agents covers the dialer side of the same question.

• FCC 22-85 (2022): ringless voicemail to a cell phone is a TCPA call
• Prior express consent required, written consent for marketing
• $500 per call, up to $1,500 if willful, under 47 U.S.C. 227(b)(3)
• Scrub the National DNC Registry and your internal list first

Slybroadcast vs an AI SDR that calls instead of dropping a voicemail

They do different jobs. Slybroadcast is a broadcast tool: you record once, it lands in thousands of inboxes, and the result depends on how many people call you back and whether someone is free to answer when they do. For a reminder, an event invite or a warm re-engagement message to people who opted in, that is cheap and it works.

An AI SDR is a conversation tool. It places the call, discloses that it is AI, answers the first objection, asks your qualifying questions and books the meeting onto a rep's calendar, then writes the outcome to your CRM. There is no callback to miss and no voicemail to compete with the other forty in the inbox.

On our pricing page Starter is $499 a month for one AI SDR seat with 250 connected minutes, Growth is $1,490 for three seats with 800, and yearly billing halves both. That is far more than $450 of drops, and it buys something drops cannot: a qualified conversation on the first touch. Many teams use both, a voicemail to warm consented contacts and the AI SDR to call the ones who respond.

• Slybroadcast: one recording, thousands of inboxes, results depend on callbacks
• AI SDR: live two way call, qualification and booking on the first touch
• Both are artificial voice calls under the TCPA and both need consent for cell phones
• Use voicemail to warm, use the AI SDR to convert
