One of the most common questions from businesses considering bulk SMS is simply: what does it actually cost? The answer varies wildly depending on the platform, volume, and what's included — so let's break it down clearly.
Pricing Models in the Industry
Per-Message Pricing
The most straightforward model. You pay a fixed rate per SMS sent, typically ranging from $0.01 to $0.05 per message depending on volume. At $0.02/message, 10,000 messages = $200. This model is transparent and predictable.
Monthly Subscription + Credits
Many platforms charge a monthly fee ($49–$299) that includes a credit bundle, with overage charges beyond that. This works well if you have consistent monthly volume but can be expensive for irregular senders.
Flat-Rate Volume Packages
Platforms like SmartBlaster sell packages: a set number of sends for a flat price. This is often the best value for campaign-style senders who blast large volumes periodically rather than dripping messages daily.
Always calculate the effective cost per message across the full package, including any platform fees, number rental costs, and compliance setup fees.
Hidden Costs to Watch For
- 10DLC registration: $4–$20/month for carrier-registered numbers in the US
- Shortcode rental: Dedicated shortcodes run $500–$1,000/month
- Opt-out management: Some platforms charge for this; others include it
- International delivery: Dramatically higher per-message costs outside North America
- Inbound replies: Some platforms charge per inbound message received
What You Should Expect to Pay
For a small business sending 5,000–10,000 messages per month, expect $100–$300/month all-in on a legitimate platform. For 50,000+ messages, volume discounts kick in and effective per-message rates drop significantly. Enterprise-level operations sending millions of messages per month negotiate custom rates directly with aggregators.
Free Trials and What They Actually Mean
Most SMS platforms offer free trials of 50–100 messages. This is enough to test delivery and interface but not enough to measure real campaign performance. Look for platforms that offer generous trial credits or money-back guarantees on your first campaign.
The cheapest bulk SMS service isn't always the best value. Deliverability, support quality, and compliance tools all affect your actual results — and a cheaper service that delivers 70% of your messages is more expensive in real terms than a pricier one that delivers 97%.
