Here’s the short answer: SMS marketing costs $0.005 to $0.01 per message segment in the U.S., with monthly platform plans starting between $19 and $39. On top of that sit carrier fees, A2P 10DLC registration, and a few surcharges most platforms don’t advertise. This guide breaks down every line item, so the bill you get matches the bill you expected.
I’m Lily Andrews, founder of Lotiva. I’ve managed campaigns across 47+ industries with $350M+ in ad spend, and SMS consistently delivers some of the strongest returns of any channel we run, as long as you know what you’re actually paying for.
Typical SMS Marketing Costs at a Glance
| Cost item | Typical range | Notes |
|---|---|---|
| Per SMS segment (U.S.) | $0.005 – $0.01 | Charged per 160-character segment, not per message |
| Per MMS message | $0.02 – $0.04+ | Roughly 2-3x the cost of SMS |
| Monthly platform plan | $19 – $39 to start | Textla $19/mo; EZ Texting ~$25/500 msgs; SimpleTexting ~$39/500 credits |
| Carrier fees | ~$0.003 per segment | Passed through from AT&T, Verizon, T-Mobile |
| A2P 10DLC registration | One-time + recurring | Mandatory for business texting on standard numbers |
| Dedicated short code | $500+/mo | Only worth it at very high volume |
| International messages | $0.05+ per segment | Varies by destination country |
Why SMS Earns Its Line in the Budget
Texts get opened. SMS runs a 98% open rate against email’s typical 20%, most messages are read within minutes, and response rates average around 45% versus roughly 6% for email. And the demand gap is real: 54% of consumers say they want promotions by text, while only 11% of businesses send them.
The cost side holds up too. You can reach your whole list for pennies per message, compared to $1+ per piece for direct mail. For flash sales, appointment reminders, and time-sensitive offers, nothing else lands as fast for as little.
What Actually Drives Your SMS Cost
Segments, not messages
This is the one that catches everyone. SMS bills by 160-character segment. Write 161 characters and you pay for two segments. Add an emoji and Unicode encoding drops the limit to 70 characters per segment. Across thousands of messages, sloppy copy quietly doubles your bill.
Message volume
Volume is your biggest lever. Send 100 messages and you might pay $0.01 each. Send 100,000 and that can drop to $0.005. Providers reward predictable volume with lower rates.
Your phone number type
Long codes (standard 10-digit numbers) are cheapest and best for two-way conversation. Toll-free numbers cost slightly more and look more established. Short codes (5-6 digits) run $500+ per month, sometimes with setup fees on top, and only make sense for very high-volume senders.
Where your recipients are
Domestic U.S. messages run $0.005 to $0.01 per segment depending on the carrier. International rates jump to $0.05 or more depending on the country.
SMS vs MMS: When Pictures Are Worth the Price
A standard SMS holds 160 characters and costs pennies. MMS carries images and video, allows longer messages, and costs roughly 2 to 3 times more, typically $0.04+ per message. A simple “20% off today” text costs a fraction of a product photo. Use MMS when the visual does the selling, like a new product drop or a before-and-after. Use SMS for everything else.
Carrier Fees and Surcharges: The Part Nobody Advertises
Mobile networks charge fees on business messages, and your SMS platform passes them to you. Twilio, for example, passes through about $0.003 per segment just for AT&T’s carrier fee. Multiply across carriers and thousands of messages and it’s real money.
- A2P 10DLC registration is mandatory if you send business texts on standard long codes in the U.S. The Campaign Registry manages it to cut spam. Expect an onboarding fee plus recurring charges tied to volume. Skip it and carriers block your messages or charge penalty rates.
- Monthly telecom surcharges are flat infrastructure fees. Textedly, for example, adds $8 per month whether you send anything or not.
- Per-user fees apply on some platforms. Textedly charges $10 per month per teammate, so five people managing campaigns is $50 that never sends a message.
- Failed message fees seem small, around $0.001 per bounce on Twilio, but a dirty contact list turns them into a recurring tax. Clean your list regularly.
Tiered Discounts: How Costs Fall as You Grow
Almost every provider prices in tiers. Twilio drops from $0.0083 to $0.0073 per segment after one million messages, and enterprise senders can negotiate committed-use discounts against guaranteed annual volume. Bulk-focused providers like Textdrip sell texts for as little as $0.012 each in large blocks. If your volume is growing, re-quote your rate every few months. Providers rarely lower it for you unprompted.
The Three Pricing Models, and Who Each One Fits
Pay-as-you-go
Perfect for startups and seasonal businesses. Send 500 texts one month and 5,000 the next without penalty. Textla offers this at $0.005 per message on a modest $19 monthly fee, with no wasted credits during slow periods.
Monthly plans
Predictable budgeting and lower per-message costs at steady volume. SimpleTexting starts around $39 for 500 credits; EZ Texting offers 500 messages for about $25 a month. The catch: most providers don’t roll over unused credits, so a 500-message plan only pays off if you actually send close to 500.
Volume and enterprise tiers
At high, consistent volume, negotiated rates make SMS remarkably cheap per message. This is where short codes and committed-use contracts start to make sense.
Affordable Platforms Compared
| Platform | Starting price | Best for |
|---|---|---|
| Textla | $19/mo + ~$0.005/msg | Lowest true cost; pay-as-you-go flexibility |
| EZ Texting | ~$25/mo for 500 msgs | Beginners; easiest interface and onboarding |
| SimpleTexting | ~$39/mo for 500 credits | Bundled automation, analytics, strong support |
| SlickText | Mid-range | Automated workflows and multi-step journeys without enterprise pricing |
| Twilio | Usage-based | Developers and high-volume senders who want raw rates |
What Your Monthly Bill Actually Looks Like
That tempting $25-a-month plan rarely tells the whole story. Add carrier passthrough fees, an occasional MMS, a telecom surcharge, and an extra teammate seat, and a “$25 plan” realistically lands between $40 and $60 depending on usage. Budget from the all-in number, not the sticker price. If you connect your SMS platform to your CRM through Zapier, factor that in too: meaningful automation usually needs a paid tier starting around $20 per month.
How to Keep Costs Down Without Killing Results
- Write inside one segment: 160 characters, no emoji, and say it plainly.
- Clean your list every month so you stop paying for bounces.
- Match the number type to the job: long code for conversation, toll-free for scale, short code only when volume demands it.
- Pick pay-as-you-go if your volume swings; pick a monthly plan only if you reliably use it.
- Re-negotiate rates as volume grows.
- Send fewer, better messages. A targeted text to 500 buyers beats a blast to 5,000 browsers on both cost and revenue.
Frequently Asked Questions
How much does SMS marketing cost per message?
In the U.S., expect $0.005 to $0.01 per 160-character segment plus roughly $0.003 in carrier fees. MMS runs $0.02 to $0.04+. Monthly platform plans start between $19 and $39.
What are A2P 10DLC fees and are they mandatory?
Yes, if you send business texts through standard 10-digit numbers in the U.S. Registration goes through The Campaign Registry, with an onboarding fee plus recurring charges based on volume. Unregistered traffic gets blocked or penalized by carriers.
Are incoming text messages free?
Usually for your customers (standard rates apply on their plan), but not always for you. Many platforms charge for inbound messages on two-way campaigns, so check the inbound rate before you build a reply-based campaign.
What’s the difference between a short code, long code, and toll-free number?
A long code is a standard 10-digit number: cheapest, best for conversation, requires 10DLC registration. A toll-free number costs slightly more and handles higher volume. A short code (5-6 digits) costs $500+ per month and is built for massive volume and brand recognition.
Is SMS marketing cheaper than email?
Per message, email is cheaper. Per result, SMS often wins: a 98% open rate and ~45% response rate mean far fewer sends are wasted. The strongest programs use both, with SMS reserved for the messages that can’t wait.
