Are you planning to launch an SMS campaign but unsure how much it will cost? Between the price per message, volumes, sending types, and tools involved, it can quickly become confusing. This comprehensive guide gives you all the keys to build a realistic SMS budget—and more importantly, to maximize your return on investment.
Professional SMS is now one of the most effective communication channels to reach your customers. With an open rate above 90% and messages typically read within 4 minutes of receipt, it clearly outperforms email and social media in terms of immediate impact. But before getting started, one question naturally arises: how much does a professional SMS campaign really cost?
Contrary to what you might think, the cost of sending SMS messages is not just about a simple price per message. Several factors come into play, and understanding them will help you not only anticipate your budget but also optimize every euro invested.
1. What Makes Up the Cost of an SMS Campaign?
The total cost of an SMS campaign is made up of several components that are important to understand to avoid surprises.
The Unit Cost per SMS
This is the most visible element. In the U.K., the price of a professional SMS generally ranges between €0.045 and €0.075 (excl. VAT) per message, depending on the volume purchased and the platform used. At Texting House, pricing is volume-based: the higher your volume, the lower the unit cost.
| SMS Volume | Unit Price | Details |
|---|---|---|
| Less than 5,000 SMS | €0.065 / SMS | Ideal for testing |
| 5,000 to 50,000 SMS | €0.055 / SMS | Regular campaigns |
| More than 50,000 SMS | €0.050 / SMS | Bulk sending |

Message Length: An Often Overlooked Factor
A standard SMS contains up to 160 characters. Beyond that, it is automatically split into multiple messages, and each part is billed separately. A 200-character message is therefore billed as 2 SMS, even if the recipient perceives it as a single message.
Golden rule: always check the actual length of your message before sending.
Destination
The cost of an SMS does not depend only on volume—the destination also plays an important role. Texting House enables SMS delivery to many countries, with pricing that varies depending on the destination.
Nearby European countries generally fall within ranges similar to UK, while some destinations in the Middle East, Africa, or Asia may have higher rates.

Platform Fees

This is one of the key advantages of our platform: no monthly subscription, no setup fees, no commitment, and no termination fees.

2. How Much Does an SMS Campaign Cost Based on Your Needs?
To help you project your budget, here are some concrete examples depending on campaign size and objectives.
Small Campaign: Testing the SMS Channel
You are an SME or an independent business owner and want to send your first message to loyal customers. You have a database of 500 opt-in contacts.
| Parameter | Value |
|---|---|
| Number of SMS | 500 messages |
| Selected volume | Pack < 500 SMS |
| Unit cost | €0.065 / SMS |
| Estimated total cost | €32.50 (excl. VAT) |
| Validity period | 18 months |
For €32.50 (excl. VAT), you can reach 500 customers with a personalized message. If just 5% respond to a €20 offer, you generate €500 in revenue—resulting in an ROI of over 15x your investment.
Medium Campaign: Seasonal Promotion
You manage a retail network and want to promote sales or a special event to 5,000 customers.
| Parameter | Value |
|---|---|
| Number of SMS | 5,000 messages |
| Selected volume | 5,000–50,000 SMS pack |
| Unit cost | €0.055 / SMS |
| Estimated total cost | €275 (excl. VAT) |
| Validity period | 18 months |
Large Campaign: Customer Retention & Regular Communication
You operate in retail or food services and send monthly SMS campaigns to a database of 20,000 contacts.
| Parameter | Value |
|---|---|
| Number of SMS | 20,000 messages |
| Selected volume | > 50,000 SMS pack |
| Unit cost | €0.050 / SMS |
| Estimated total cost | €1,000 (excl. VAT) |
| Estimated yearly cost (12 campaigns) | €12,000 (excl. VAT) |
At this scale, SMS remains one of the cheapest communication channels per contact: €0.05 per customer reached, compared to several euros for display campaigns.
3. How to Maximize the ROI of Your SMS Investment
The cost of a campaign is only part of the equation. What truly matters is what you get in return. Here are the key levers to make every euro of your SMS budget work harder.
Segment Your Database: Send Less, but Better
A common mistake is sending the same message to your entire contact list. This leads to unnecessary opt-outs and reduces campaign impact.
By segmenting your audience—based on purchase behavior, geographic location, last visit, or order frequency—you reduce your sending volume while significantly increasing your conversion rate.
Example: instead of sending a general promotion to 10,000 contacts, target the 2,000 customers who haven’t purchased in 60 days with a personalized reactivation message.
Optimize Your Copy to Avoid Multi-SMS Costs
Every character matters. A message exceeding 160 characters is automatically split, doubling or tripling your cost.
Use a character counter before sending, avoid unnecessary special characters, and choose short, impactful wording. This also improves message effectiveness.
Send at the Right Time
Timing has a direct impact on read and conversion rates. According to several studies, the most effective time slots are:
- Weekdays: lunchtime (12 pm–2 pm) or late afternoon (around 5 pm)
- Weekends: Saturday morning for retail, leisure, and food-related offers
- To avoid: certain hours are legally restricted depending on your country’s regulation.
A well-timed SMS is read almost instantly, while a poorly timed message can feel intrusive and increase unsubscribe rates.
Use Automation to Optimize Costs
With Texting House automation features (via API or integrations like HubSpot or Zapier), you can send SMS messages triggered by specific events.
These automated scenarios are often the most profitable because they reach customers at the exact moment of highest intent:
- Welcome SMS after sign-up
- Appointment reminder 24 hours before
- Order or shipping confirmation
- Personalized birthday offers
These targeted messages generate significantly higher conversion rates than generic campaigns, at the same cost per message.
Measure, Adjust, Repeat
An SMS campaign that isn’t analyzed is a missed optimization opportunity. After each campaign, track these key metrics:
ROI formula:
ROI (%) = (Revenue generated – Campaign cost) / Cost × 100
Example: €3,000 revenue from €200 spent = 1,400% ROI
| KPI | What it measures | Ideal target |
|---|---|---|
| Deliverability rate | SMS successfully received | > 95 % |
| Click-through rate (CTR) | Clicks on included link | 6-16 % |
| Conversion rate | Completed actions | Depends on objective |
| Unsubscribe rate | STOP replies / delivered messages | < 1 % |
4. SMS vs Other Channels: Cost per Contact Comparison
To better understand SMS pricing, here’s how it compares with other marketing channels:
| Channel | Avg. Cost per Contact | Avg. Open Rate | Avg. ROI |
|---|---|---|---|
| SMS (Pro) | €0.05 – €0.07 | > 90 % | High |
| €0.01 – €0.05 | 15 – 25 % | Medium | |
| Direct Mail | 0,50 – 1,50 € | ~60 % | Variable |
| Display Ads | €0.20 to €5 CPM | < 2% (clicks) | Low |
Professional SMS stands out with an exceptional cost-to-performance ratio: for a slightly higher unit cost than email, it delivers 4 to 5 times higher open rates.
5. Choosing the Right SMS Platform: What to Check
Your SMS provider directly impacts both your costs and delivery quality. Here’s what to evaluate:
- Pricing transparency: are prices clearly displayed? Any hidden fees?
- Routing quality: direct operator routes or grey routes?
- Data security: GDPR compliance? ISO 27001 and ISO 9001 certified?
- Credit validity: flexible validity period?
- Integrations: compatibility with your tools (CRM, e-commerce, HubSpot, Zapier)?
- Customer support: responsive and accessible?
At Texting House, all these criteria are met. Our platform is ISO 27001 and ISO 9001 certified, requires no development to set up, and gives you immediate access to a pricing simulator to estimate your budget in real time.
