Which statement is true regarding customer engagement through various channels?

The statement that SMS/MMS is effective for urgent communication is true because these channels are known for their immediacy and high open rates. Messages sent via SMS or MMS typically reach users within minutes, making them ideal for time-sensitive information, such as alerts, reminders, or emergencies. The direct nature of SMS also means that users often notice these messages quickly, which contributes to their effectiveness in conveying urgent communications.

In contrast, while email can be fast, it does not guarantee immediate attention due to factors such as inbox clutter and delayed notification settings. Push notifications can be useful, but they are not universally the best for all types of messages, as they may not be appropriate for longer or more detailed information. Lastly, the assertion that all channels have the same user engagement rates overlooks the distinct characteristics and effectiveness of each communication channel, which vary widely based on the audience and context.
