Email vs. Text Marketing: Costs for Small Businesses
Email costs less in all 10 scenarios I compared. For 500–10,000 contacts receiving one or two campaigns per month, my hypothetical estimates range from $20–$150 for email and $44–$317 for SMS. I’d budget for routine email campaigns first, then use texts when timely reminders could bring in enough added profit to cover the cost.
The difference comes down to billing: email includes a send allowance, while SMS charges add up with each message segment. Longer texts, emojis, carrier charges, and registration fees can change your total.
Quick Comparison
| Cost factor | SMS | |
|---|---|---|
| Pricing model | Contact-based monthly tiers | Monthly base plus per-segment charges |
| Monthly total in my examples | $20–$150 | $44–$317 |
| Sending allowance | 10× the contact limit | $0.014 per outbound segment |
| Fixed recurring fees | None beyond the plan assumed | $37, including the base plan |
| One-time setup | $0 assumed | $19 estimated |
| Main budget checks | Contact tiers, send caps, and overages | Message length, carrier fees, number rental, registration, media, and automated sends |
These are budgeting estimates in U.S. dollars – not current price quotes. They exclude labor, taxes, and optional add-ons. Before choosing a plan, I’d compare <u>the full monthly bill</u> using your audience size, sending frequency, and expected text length – not just the advertised fee.
What Goes Into Email and SMS Bills
The models below are hypothetical budget estimates, not advertised offers. Here are the billing rules used in the monthly comparisons.
| Billing component | Email model | SMS model |
|---|---|---|
| Subscription | Tiers by contact count | $25/month plus usage charges |
| Contact limits | Up to 500: $20; 1,000: $30; 2,500: $60; 5,000: $100; 10,000: $150 per month | No contact-storage fee assumed; sending drives usage charges |
| Send allowance | Monthly sends equal to 10× the contact limit | Usage charges increase with each segment sent |
| Message charges | Included sends: $0 extra; overages: $1 per 1,000 emails beyond the allowance | About $0.014 per outbound segment |
| Additional recipient | No extra charge until the contact tier limit is exceeded | Each additional recipient adds another segment charge |
| Other recurring fees | None assumed | $2/month number rental plus $10/month 10DLC campaign fee |
| One-time setup | $0 assumed | 10DLC registration and vetting, estimated at $19 |
| Cost structure | Fixed until a contact tier or send allowance is exceeded | Fixed monthly fees plus metered usage |
These assumptions keep the comparisons consistent across audience sizes.
Email Plans, Contact Limits, and Send Allowances
Email providers can bill by contact count, send volume, or both. Our model uses contact tiers with send allowances. Before choosing a plan, check what happens when you exceed the allowance: an overage charge, an automatic upgrade, or a sending pause.
Also check whether inactive, unsubscribed, or duplicate contacts count toward your bill, and whether forms and landing pages cost extra. Our calculations exclude optional upgrades.
SMS Plans, Message Segments, and Fees
For this model, monthly SMS cost = $37 + (outbound segments × $0.014). The $19 setup charge applies only in the first month. We assume a local 10-digit number, which requires 10DLC registration. Toll-free and short-code routes have different requirements and costs.
SMS usage charges depend on segments, not contacts. Multipart messages generally allow 153 GSM-7 characters or 67 Unicode characters per segment because the join header takes up space. Before estimating your bill, check segment length, number rental, carrier surcharges, and 10DLC fees.
The next section uses these assumptions to compare monthly totals for 500 to 10,000 contacts.

Cost Differences and Break-Even Points
Here’s how the totals compare at each list size and campaign count.
| Contacts | Campaigns/month | Email total | SMS total | SMS costs more by | Lower-cost channel |
|---|---|---|---|---|---|
| 500 | 1 | $20.00 | $44.00 | $24.00 | |
| 500 | 2 | $20.00 | $51.00 | $31.00 | |
| 1,000 | 1 | $30.00 | $51.00 | $21.00 | |

Email costs less in every example, with no break-even point shown. If your list moves into a higher pricing tier or your texts need multiple segments, run the numbers again before setting budget limits. The next section covers ways to keep either channel within budget.

Lower-Cost Choices by Audience and Frequency
Use email for routine updates and longer promotions. Save SMS for time-sensitive messages. A text earns its higher price only when it brings in enough added profit.
| Audience | Campaigns/month | Lower-cost choice under this model | Why it’s cheaper | Cost risk | Plan detail to verify |
|---|---|---|---|---|---|
| 500 | 1 | Fits within a low-volume email plan or free tier | SMS registration and recurring fees | Contact limit and send allowance | |
| 2,500 | 1 | Email plans usually cover this volume at a flat monthly rate | Longer texts can create extra segments | SMS segment rate and encoding | |
| 2,500 | 2 | The second campaign still fits within the email allowance | Automations can add text sends | Whether automations use the same send allowance | |
| 10,000 | 2 | Email still tends to cost less at higher volume | SMS media or extra segments increase usage | Overage rates and per-message fees |
Here’s how that split can work in a mixed-channel send.
Hypothetical mixed-channel example: A local boutique emails a monthly “New Arrivals” lookbook to 2,500 subscribers, then sends one short flash-sale reminder to just 300 VIP customers who specifically opted into text alerts. Email carries the product details; SMS reaches a smaller audience while the offer is still timely.
To see whether the text pays off, compare the same audience with and without SMS. Measure incremental orders and contribution margin, then subtract texting costs. Judge results by clicks, orders, and contribution after sending costs – not open rates alone.
Before approving a send, check the fees below.
Extra Fees and Monthly Budget Checks
| Check before sending | SMS | |
|---|---|---|
| ☐ Overages | Verify contact-tier increases, send caps, and overage rates. | Verify per-segment charges, credit expiry, and rates beyond included usage. |
| ☐ Carrier fees | N/A | Check whether carrier charges are included so you don’t add them twice. |
| ☐ Authentication or registration | Domain authentication is usually free. | Check registration, vetting, monthly campaign fees, and number rental. A2P 10DLC registration applies to business texting from U.S. 10-digit local numbers. |
| ☐ Media charges | Usually included. | Confirm MMS pricing before attaching images or GIFs. |
| ☐ Automation add-ons | Often included. | Budget for both workflow access fees and the texts those workflows send. |
| ☐ Applicable taxes | Excluded from these scenarios; may appear on invoices. | Excluded from these scenarios; may apply to subscriptions and usage. |
For SMS, calculate recipients × campaigns × expected segments, including automated sends. Check the editor’s segment counter: emojis or certain special characters can change encoding and increase the segment count.
Before sending, also check charges for failed and undelivered messages, credit expiration, and overage rules.
Conclusion: Compare Total Costs, Not Just Plan Fees
The sample totals show a clear pattern: under these assumptions, email usually costs less for recurring outreach. Use SMS only when speed is worth the higher cost.
Use the tables to guide your budget – not as a price quote. Replace the assumptions with your actual rates, and recalculate when your audience size, send frequency, message length, or media changes.

FAQs
How many extra sales would justify my SMS costs?
To find how many extra sales you need to cover your monthly SMS costs, divide your total monthly SMS costs by your profit per sale. Include subscription fees, per-segment charges, carrier fees, number rental, and any registration or campaign costs. Round up to the next whole sale.
For example, if SMS costs $100 per month and each sale or filled appointment brings in $60 in profit, you need two additional sales to cover the cost.
Use your own costs and profit per sale to get an accurate estimate.
How should I split my email and SMS budget?
Build your email program first for regular communication, lower per-message costs, and room to grow. Add SMS for time-sensitive messages, like appointment reminders or limited-time offers. Use email when readers need more detail. If a message needs both explanation and urgency, lead with email.
Track each channel’s ROI to guide your budget, factoring in SMS send costs and platform fees. Aim to reinvest 10%–20% of email-attributed revenue into your marketing program.
Could SMS cost less for my smaller customer list?
SMS usually costs more than email – even with a small list – because you pay for each delivered message. For 1,000 subscribers, a single campaign typically costs $0–$1 for email under per-send billing, compared with roughly $7–$12 for SMS. The SMS estimate includes published per-message rates and standard carrier fees.
SMS can still be cost-effective for time-sensitive sales that draw strong engagement. But costs climb fast as your audience grows and you send more often.
