Custom Sender Overview

A Custom Sender, also known as an Alphanumeric Sender ID, allows you to replace the standard phone number used for sending SMS messages with a custom name. Instead of appearing as a numeric phone number, your messages will display your brand or company name in the recipient’s inbox. See Send an SMS to learn more.

This feature is widely used for marketing, alerts, and other one-way notifications where replies are not needed or expected.

Brand Visibility and Recognition

With a Custom Sender, recipients immediately see who the message is from.

For example, instead of displaying a number such as +46 70-123 45 67  , the message might appear from HelloSMS or MyCompany. This improves brand recognition and helps build trust at first glance.

Professional Presentation

Using a clear, recognizable sender name adds credibility and professionalism to your SMS communications. It reassures recipients that the message is legitimate and directly connected to your brand.

One-Way Messaging

Because Custom Senders cannot receive replies, they are ideal for high-volume promotional campaigns or automated notifications. This can reduce the need to manage inbound messages and streamline communication workflows.

Custom Senders help you instantly build trust and recognition by clearly displaying your brand name for all one-way alerts and marketing messages.
