SMS Messaging, Opt-Outs, and Compliance

Chekkit helps businesses communicate with customers via text message, adhering to mobile carrier rules and best practices. This article explains how text message opt-outs work, why you may see opt-out language in messages, and how compliance protects message delivery.

How Customers Can Stop Receiving Text Messages

Customers are always in control of the messages they receive.

If a customer no longer wants to receive text messages, they can simply reply with one of the following keywords:

STOP, STOPALL, UNSUBSCRIBE, CANCEL, END, or QUIT

Once one of these keywords is sent:

The customer is automatically unsubscribed
No further text messages will be sent from that business
This applies to all future reminders, follow-ups, and campaigns

If a customer later changes their mind, they can reply START to the same number to resubscribe.

Why Messages Include “Reply STOP to Unsubscribe”

Mobile carriers require that businesses clearly explain how customers can opt out of text messages.

For this reason:

The first message a customer receives will include opt-out instructions
If messaging continues over time, opt-out language may appear again periodically

This ensures transparency and gives customers full control over their preferences.

Why This Matters for Message Delivery

Wireless carriers actively filter text messages to protect users from spam and unwanted messages.

Messages are more likely to be delivered successfully when:

Customers have opted in to receive texts
Messages clearly identify the business sending them
Opt-out instructions are included
Opt-out requests are respected immediately

If these standards are not followed, messages may be delayed, filtered, or blocked by carriers.

What Chekkit Does to Protect Customers

Chekkit automatically helps businesses follow carrier rules by:

Honoring opt-out keywords automatically
Including required opt-out language
Preventing messages from being sent to unsubscribed contacts
Monitoring messaging health to reduce filtering

These protections are in place to ensure customers only receive messages they expect and want.

FAQs

How do I stop receiving text messages?

Reply STOP, UNSUBSCRIBE, CANCEL, END, QUIT, or STOPALL to the message. You will be unsubscribed immediately and won’t receive further texts from that business.

Will I receive a confirmation after opting out?

Yes. You may receive a final confirmation message letting you know that you have been unsubscribed. No additional messages will be sent after that.

Can I start receiving messages again later?

Yes. If you previously opted out, you can reply START to the same number to resubscribe and begin receiving messages again.

Why do messages say “Reply STOP to unsubscribe”?

Mobile carriers require businesses to clearly explain how customers can opt out of text messages. This language ensures transparency and gives you control over your messaging preferences.

Why does opt-out language appear more than once?

If a business messages you over an extended period of time, carriers require opt-out instructions to be shown again occasionally to make sure customers are aware of their options.

What happens when I opt out?

Once you opt out:

The business can no longer send you text messages
You will not receive reminders, follow-ups, or campaigns
Your opt-out is respected automatically by the system

Can a business still see my previous messages after I opt out?

Yes. Opting out stops future messages, but the business may still see previous conversation history for record-keeping purposes.

What if I believe I’m receiving messages by mistake?

If you believe you received a message in error, reply STOP to unsubscribe immediately, then contact the sender directly to confirm your preferences.

No. Chekkit does not sell or share customer phone numbers. Messages are sent only on behalf of the business you interacted with.

Why didn’t my message go through?

In rare cases, mobile carriers may delay or filter messages to protect users from spam. This usually relates to carrier rules and is not controlled by the business or Chekkit.
