SMS Notification Consent And Opt-Out Best Practices

Before sending SMS notifications for deliveries or routing updates, you must have permission from the customer. You must also give them a simple way to stop receiving messages.

To get clear consent:

• Get explicit consent directly from the customer. Never assume permission based on past interactions.
• Clearly explain what types of messages they’ll receive and how often.
• Avoid using vague or misleading language during sign-up.

To provide easy opt-out:

• Include a “Reply STOP to unsubscribe” line in the first message.
• Repeat opt-out instructions at least every few messages.
• Honor opt-out requests immediately and remove those numbers from future sends.

Consent and opt-out practices aren’t just legal requirements. They also help maintain trust and prevent your messages from being blocked by mobile carriers.

Build Trust By Identifying Your Business In SMS Notifications

Since SMS messages often come from unfamiliar numbers, it’s essential to make your business instantly recognizable. Starting every message with your business or app name builds trust and helps customers quickly understand the purpose of the message.

Best practices for sender identification: 

• Start each SMS with your company or app name (e.g, “Route4Me…”).
• Use a consistent sender name or ID so customers can easily recognize your messages.
• Use a professional tone and avoid emojis, slang, and excessive punctuation.
• Keep messages clear, concise, and focused on routing or delivery information.
• Maintain a polite, helpful tone that reflects your brand’s values and encourages positive customer interactions.

A consistent, clear sender identity helps prevent confusion and reduces the chance of your messages being flagged as spam.

Essential SMS Touchpoints For Route Optimization

Keep SMS messages short, relevant, and focused on the customer’s delivery or service experience. Only send notifications when they’re timely and helpful, ideally during key points in the last mile journey.

Examples of last mile-related SMS messages: 

• ETA: “Your order will arrive between 2:00 – 2:30 PM.”
• Arrival Alert: “Your driver is at the location now.”
• Tracking: “Track your delivery: route4me.com/track1234”

Timing recommendations:

• Send reminders 1 day and 1 hour before the scheduled delivery.
• Send an ETA alert 15 – 30 minutes before arrival.
• Avoid messaging during early morning or late-night hours.

Well-timed, clear notifications help customers stay informed without feeling overwhelmed. Remember: if you serve customers across different regions, tailor your messaging to local time zones whenever possible.

Use Actionable, Customer-Focused Language

How you write SMS notifications matters as much as when you send them. Clear, helpful language will minimize confusion, improve customer satisfaction, and even reduce failed deliveries.

Make notifications clear and specific: 

• State clearly what the customer needs to do (confirm a delivery time, reschedule, etc.).
• Use narrow, accurate delivery windows to reduce uncertainty.
• Avoid vague phrases like “Your order is on the way” without a timeframe or link.

Make notifications engaging and relevant:

• Personalize messages with the customer’s name or order number.
• Use plain, universal language. Avoid regional slang that may confuse customers in different areas.
• End notifications with a simple, courteous phrase to foster a positive brand impression.

Thoughtful, customer-focused language both improves message clarity and shows customers that you respect their time, understand their needs, and are committed to providing a seamless delivery or service experience.

Optimize Notifications With Branded Links And Spam-Free Language

Using branded or secure links in your SMS notifications builds customer confidence and reduces the risk of your messages being flagged as spam. At the same time, using clear, non-promotional language also helps lower the chance of spam filtering.

Best practices for links:

• Use your business domain or a custom short link that reflects your brand.
• Include tracking URLs like “route4me.com/track1234” for transparency.
• Avoid free shorteners like TinyURL or Bitly.

Avoid promotional language that can trigger spam filters:

• Promotional terms like “Free,” “Limited Time,” or “Offer”.
• Urgency triggers that sound like spam.
• Content that may cause customers to opt out or carriers to block messages.

As an extra precaution, always run internal tests to ensure everything appears as intended: check that links work and that your messaging remains clear and non-promotional.

Avoid Prohibited Content In Regulated Industries

Mobile carriers strictly prohibit certain type of content, even if legal in some states or regions. These restrictions apply regardless of whether your messages are operational or promotional.

Avoid references to the following:

• Cannabis, CBD, or THC
• Vape products
• Prescription medications
• Firearms or ammunition
• Gambling or betting

Even indirect or casual mention of these topics can lead to message filtering. If your enterprise is in a regulated industry (such as cannabis delivery), coordinate with legal and compliance teams to ensure messages meets both carrier and legal guidelines.

Follow Carrier Compliance For SMS Communications

To avoid carrier filtering or penalties, it’s important to follow all applicable regulations and guidelines.

Compliance tips: 

• Stay current on SMS regulations and carrier guidelines.
• Avoid using SMS for marketing, promotions, or upselling.
• Use SMS only for delivery updates, routing information, and customer support.
• Stagger message sends when possible to avoid volume spikes that can trigger carrier rate limits.
• Avoid sending large batches of SMS at the top of the hour or during peak carrier traffic times.

Carriers have strict rules around content, frequency, and message type, especially for businesses using SMS for operational purposes like delivery updates.
