TCPA SMS Compliance for US Small Businesses

TCPA SMS compliance means your business must send SMS messages only to people who have given prior express consent, provide a clear way to opt out, and keep records of these permissions to avoid legal penalties. (docs.fcc.gov) This article covers why compliance is important for small businesses, step-by-step actions to take, a practical example, common mistakes, and how HelloGrowthCRM can help manage SMS communications.

Why this comes up / what goes wrong

Small-business owners often want to use SMS for quick, direct communication with leads and customers because it feels personal and immediate. However, many don’t realize that the Telephone Consumer Protection Act (TCPA) strictly limits how and when you can send these texts. Without proper consent, you risk costly lawsuits or fines. Common issues include texting people without documented permission, failing to include opt-out instructions, or mixing personal and business contacts without clear consent. This confusion especially affects businesses that run sales on text messages and spreadsheets, lacking a clear system to track permissions.

Step-by-step

1. Obtain prior express written consent: Before sending any marketing SMS, get explicit permission from the recipient. This can be via a web form, text opt-in, or written agreement. Make sure the consent clearly states they agree to receive texts from your business.

1. Provide clear opt-out instructions: Every SMS message must include a simple way for recipients to stop receiving messages, commonly by replying "STOP".

1. Keep detailed records of consent: Document when, how, and what the recipient agreed to. Store this safely to defend your compliance if challenged.

1. Limit message content and timing: Avoid sending messages outside reasonable hours (typically 8 AM to 9 PM local time) and ensure messages are relevant to the consent given.

1. Train your team and use compliant tools: Educate sales and marketing teams on TCPA rules. Use software that logs consent and opt-outs automatically.

1. Regularly review and update consent: People may change their minds. Periodically confirm permissions and remove contacts who have opted out.

1. Respond promptly to opt-out requests: When a recipient opts out, stop all messages immediately to avoid violations.

1. Monitor and audit your SMS campaigns: Regularly check message logs, consent records, and opt-out compliance to catch issues early.

Example (fictional figures)

A B2B software reseller in Denver, Colorado, sends SMS marketing to prospects. They collect consent via a web form on 01/15/2026.

• Number of contacts who gave consent: 1,000
• Cost per SMS sent: $0.05
• Total SMS sent per month: 500

Calculate monthly SMS cost: $0.05 × 500 = $25

If 2% of recipients opt out monthly: 500 × 2% = 10 opt-outs

They must update their records to remove these 10 contacts immediately to stay compliant.

This example shows the importance of tracking consent, costs, and opt-outs for TCPA SMS compliance.

Common mistakes

• Not getting written consent: Prevent by using clear opt-in forms or text keywords.
• Ignoring opt-out requests: Always stop sending messages immediately after an opt-out.
• Mixing personal and business contacts without consent: Separate lists and verify permissions.
• Failing to document consent: Use software or spreadsheets to log when and how consent was obtained.
• Sending messages at inappropriate times: Schedule messages within allowed hours.
• Using generic mass texts without personalization: Tailor messages to the consented purpose.
