Key Takeaways

A reliable SMS program starts with documented consent, clear disclosures, registered sending numbers, and systems that process opt-outs correctly.
Before every campaign, verify the audience, review the message, confirm the send time, and test the full experience on a mobile device.
Consent records, suppression lists, and current templates should be reviewed regularly so older workflows do not create compliance or deliverability problems.
SMS platforms with built-in compliance, automation, contact management, scheduling, and reporting tools can reduce the amount of manual oversight required.

The SMS Marketing Compliance and Launch Checklist

One of the major advantages of SMS marketing is its ease of use. Even small and midsize businesses can create campaigns and send messages without large marketing teams or extensive budgets. On the other hand, because SMS is so straightforward to use, it can be easy to miss some of the requirements involved in setting it up correctly. An incomplete opt-in disclosure, a missed opt-out request, an unregistered sender, or a poorly configured workflow can create problems for the business and its audience

This SMS marketing checklist provides a structured way to review your program before you send, from consent collection and platform setup through message review and scheduling.

A complete SMS marketing checklist should cover eight areas, beginning with the platform and consent process and ending with documentation. Taken together, these checks can help you establish a program that follows applicable SMS best practices and industry standards, gives subscribers appropriate control, and makes campaigns easier to manage.

Because requirements can vary based on your message type, sending technology, location, and industry, businesses should also review applicable state laws and seek qualified legal advice when needed.

Step 1: Choose a Compliant SMS Marketing Platform

Your SMS platform should make it easier to manage consent, opt-outs, sender registration, and message delivery without relying on manual processes. For a small or midsize business, useful features include built-in compliance controls, automatic opt-out handling, consent records, campaign reporting, scheduling, and support for sender registration.

If you send business messages from a U.S. 10-digit long code, confirm that your provider supports A2P 10DLC registration. U.S. carriers require business traffic using these numbers to go through an approved A2P campaign, and unregistered traffic can be blocked or filtered.

EZ Texting’s compliance tools help manage consumer-driven consent and opt-outs, including automatically removing contacts from future communications when they reply STOP. The platform also supports A2P 10DLC registration, allowing businesses to handle registration and campaign management within the same system.

Step 2: Confirm Opt-In Consent Is Collected Correctly

Do not treat possession of a mobile number as permission to send marketing texts. A number collected for an order, appointment, account, or email subscription may have been provided for a different purpose.

FCC rules require prior express written consent for covered telemarketing texts sent using an automatic telephone dialing system or artificial or prerecorded voice. More broadly, CTIA guidance recommends that businesses and other non-consumer senders obtain clear opt-in consent before texting consumers.

As such, it’s always best to collect documented, affirmative SMS permission before adding anyone to a promotional list. These can be obtained through:

Website forms
Checkout forms
SMS keyword opt-ins
QR codes
Other clearly disclosed enrollment methods

Keep SMS consent separate from email consent so people can choose each channel independently. You might also use double opt-in, where a subscriber confirms enrollment after the initial sign-up. It is not universally required for recurring SMS programs, but it can provide an additional record showing that the subscriber made a conscious and informed decision to join.

Don’t view opt-in as a negative; when audiences know what to expect and have the option not to participate, you’re left with those who are interested and willing to potentially commit. In fact, according to EZ Texting’s 2026 Consumer Texting Behavior Report, 62% of consumers opt in to business texts before making their first purchase.

Step 3: Verify Opt-In Disclosure Language Is Complete

A subscriber should know what they are agreeing to before submitting a phone number. FCC rules define a clear and conspicuous disclosure as one that is apparent to a reasonable consumer and separate and distinguishable from surrounding advertising or other disclosures. For covered prior express written consent, the agreement also needs to make clear that consent is not a condition of purchasing goods or services.

CTIA guidelines and carrier requirements also call for additional information at SMS sign-up points. Depending on the program, your disclosure should address:

The business or program sending the texts
The type of messages the subscriber should expect
Expected or variable message frequency
The statement that message and data rates may apply
How to opt out (typically by replying STOP)
Customer-help information and links to applicable terms and privacy information

Check every opt-in touchpoint to make sure the required disclosure language is present, easy to read, and visible before the subscriber signs up. If someone has to search for the disclosure or cannot reasonably read it before enrolling, the consent process may not meet the clear and conspicuous standard.

Step 4: Confirm Your Welcome Message and Confirmation Flow Are Set Up

Recurring messaging programs should confirm enrollment and establish expectations immediately. CTIA short-code guidance calls for an opt-in confirmation message for recurring-message programs, including the program or brand, opt-out information, customer-care information, frequency disclosure, and notice that message and data rates may apply. Use the confirmation message to deliver any promised incentive, such as a discount code, and reinforce what the subscriber agreed to receive.

Automate the process so the confirmation is triggered by the sign-up rather than relying on someone to send it manually. EZ Texting automation supports trigger-based messages, and its workflow templates include welcome sequences for keyword and sign-up-form subscribers.

Before promoting the program, opt in with a test number. Check the message itself, the enrollment path, and the timing of the response.

Step 5: Set Up Automated Opt-Out Processing

Subscribers must have a reliable way to revoke consent. Current FCC rules recognize replies including STOP, QUIT, END, REVOKE, OPT OUT, CANCEL, and UNSUBSCRIBE as reasonable revocation methods. Other wording can also count when a reasonable person would understand it as a request to stop receiving messages, but as this is open to interpretation, it’s typically better to err on the side of caution.

Covered revocation requests must be honored within a reasonable time, no later than 10 business days after receipt. Operationally, there is little reason to keep sending marketing texts during that period.

Automatic suppression reduces the chance that a scheduled campaign or workflow will contact someone after the person has asked to leave. Maintain the opt-out status rather than simply deleting the contact. Periodically test this process yourself. Reply STOP from a test number, then verify that later promotional sends are suppressed.

EZ Texting

With EZ Texting, an opted-out number is blocked from receiving further messages from the sending number, and the status is retained even if someone attempts to upload the number again.

Step 6: Review Message Content for Compliance

Keep campaign content consistent with the program subscribers agreed to join. Before sending, make sure your business is clearly identified, promotional claims are accurate, links lead to the expected destination, and the message follows your provider’s acceptable-use rules.

Pay particular attention to restricted content. The CTIA Short Code Monitoring Handbook identifies SHAFT content, covering sex, hate, alcohol, firearms, and tobacco, as categories that may be prohibited or subject to additional wireless-provider requirements. Gambling, sweepstakes, and contests can face additional restrictions as well. Build a content review into your pre-send process, and recheck reusable templates whenever an offer, claim, or campaign purpose changes.

Step 7: Configure Send Time Controls

FCC rules generally prohibit telephone solicitations before 8 a.m. or after 9 p.m. in the recipient’s local time, and the FCC applies its telemarketing and solicitation rules to covered marketing texts sent to wireless numbers. State laws can impose tighter limits, so campaign scheduling should account for each recipient’s location. For example, a campaign scheduled for 8 a.m. in your time zone could reach subscribers elsewhere before their permitted sending window begins.

Build local-time review into your scheduling and account for any states with narrower permitted windows. EZ Texting provides scheduled campaign and automation tools that can help you control when campaigns are deployed.

Step 8: Establish a Consent Audit Trail

If a subscriber questions why they received a message, you need records that show how the person entered the program. A useful consent record captures the phone number, opt-in date and time, collection method, program involved, and the disclosure presented when permission was granted.

Preserve versions of your forms and disclosures as they change. A timestamp showing that someone submitted a form is considerably more useful when you can also establish what that form said on that date.

Ask your provider what consent and messaging records it retains, how long they are available, and whether you can export them. Documentation should remain accessible enough that you can respond to a complaint or regulatory inquiry without reconstructing enrollment history from several disconnected systems.

Because phone numbers can change hands, list accuracy should be reviewed on a regular, ongoing basis.

Pre-Campaign Launch Checklist

Once the program itself is configured, complete a smaller review before every campaign. This catches changes in the audience, message, or schedule that a one-time setup audit cannot anticipate.

Contact List Verification

Review the audience selected for the campaign before you send. Confirm that each contact belongs on the list and that the audience matches the purpose of the message.

Verify consent: Every recipient should have the appropriate permission to receive the type of message you plan to send.
Check suppression status: Remove anyone who has opted out or otherwise appears on your internal suppression list.
Confirm the segment is relevant: A location-specific promotion should only reach subscribers in the applicable area, while an offer intended for existing customers should exclude contacts who have not purchased.
Remove invalid contacts: Check for bounced, inactive, or invalid numbers that should no longer receive marketing messages.

Because phone numbers can change hands, list accuracy should be reviewed on a regular, ongoing basis.

A 90-day review cycle is a useful starting point for checking whether your SMS list still contains valid, engaged subscribers, although some businesses may need to review their lists more often. EZ Texting contact management allows businesses to organize contacts into groups, remove bounced numbers, and maintain unsubscribed status.

Message Review

Read the final message before scheduling it and verify that the sender is identifiable, the offer or information is accurate, and the call to action leads to the correct destination. Check links, discount codes, dates, pricing, and other details that could create confusion if entered incorrectly. Make sure any required opt-out language is included and that the content remains consistent with what subscribers agreed to receive.

Apply the same review to automated messages before activating a workflow. Because these messages continue sending when contacts meet the trigger conditions, an error can affect multiple subscribers before anyone notices it. Assign someone to approve new templates and recheck them whenever the offer, product information, or campaign terms change.

Timing and Scheduling Confirmation

Before scheduling a campaign, make sure the send time falls within the permitted hours for every recipient based on their local time and any applicable state laws. Check your campaign calendar at the same time. Even when two messages fall within permitted sending hours, delivering them too close together can create unnecessary frequency for subscribers who belong to overlapping campaigns.

Use your own campaign results to refine scheduling within the permitted windows. EZ Texting reporting tools track metrics such as clicks, responses, opt-outs, and engagement trends, giving you data you can use to identify when your audience tends to respond.

Test the Campaign Before Sending

Send a test message to yourself or someone on your team before launching the campaign.

Check how it appears on a mobile device
Verify every link
Verify discount codes and campaign details
Confirm that destination pages load correctly
Test any replies or automated actions the message is meant to trigger

This final check can catch problems that are easy to miss when reviewing the campaign inside the platform.

SMS Compliance Checklist for Existing Programs

If you already run SMS campaigns, schedule recurring audits rather than assuming your original setup still reflects current requirements. Review the program whenever you introduce new message types, expand into new states, change how you collect opt-ins, or make significant changes to automated workflows.

During each audit, confirm that:

Active subscribers have documented consent: Make sure you can verify when and how each contact agreed to receive marketing texts.
Current opt-in points contain the required disclosures: Check forms, sign-up pages, and other enrollment methods against your current consent language and program terms.
Opt-out processing works correctly: Test standard opt-out keywords and confirm that suppressed contacts are excluded from scheduled campaigns and automated workflows.
Templates and workflows still meet current requirements: Review active messages, particularly older ones that may not have been checked since they were created.
Your program reflects current guidance: Revisit applicable FCC rules, state requirements, and CTIA messaging guidance as regulations and industry standards change.

Document any issues you find and resolve them before the next campaign send.

Frequently Asked Questions About SMS Marketing Checklist

A TCPA compliance checklist focuses on legal requirements such as consent, revocation, and calling-time restrictions. An SMS marketing checklist is broader and can also cover platform setup, sender registration, message quality, testing, scheduling, segmentation, and performance review.

Review it on a recurring basis and whenever you make significant changes to your program, such as adding new campaign types, changing opt-in methods, expanding into new states, or updating automated workflows.

Not entirely. Promotional and transactional messages can be subject to different consent and content requirements, so the checklist should be adjusted based on the purpose of the messages being sent.

Stop or correct the affected process as quickly as possible, preserve relevant consent and campaign records, and review whether any additional remediation is needed. For significant issues, consult qualified legal counsel.

Yes. State laws can impose requirements that are stricter than federal rules, so businesses with subscribers in multiple states should account for the laws that apply to each recipient’s location.

If you send business messages from a U.S. 10-digit long code, A2P 10DLC registration should be part of your platform and sender-setup review. Registration helps carriers identify legitimate business traffic and reduces the risk of filtering or blocking.
