SMS Marketing Best Practices

To prevent your SMS messages from being flagged as spam, we've outlined below some best practices you can follow when running SMS marketing campaigns.

What is SMS Marketing?

SMS Marketing is a fast and simple communication channel that delivers high conversion rates.

It involves sending text messages to a predefined list of contacts with content related to new opportunities, promotions, and updates.

Best Practices for SMS Marketing

• Clearly introduce your business at the beginning of the message;
• Avoid long messages;
• Minimize the use of capital letters (caps lock);
• Limit the use of special characters;
• Share shortened links properly;
• Place links within the sentence, not at the very end of the text;
• Never send empty or incomplete links like: “[https://www.”]();
• Always provide an option to unsubscribe from future communications;
• Make your messages feel human and personalized.

We also recommend:

• Do not send messages without the user’s consent;
• Avoid sending multiple messages at once, as this is discouraged and may overwhelm the recipient.
