An approval process for sending may not affect the freshness of the data.

Ensuring preferred channel is available in subscriber data is the correct answer. This option allows you to use dynamic content or decision splits in Journey Builder to honor the opt-in communication me thod of your subscribers. For example, you can use an attribute or a data extension field that indicates whether a subscriber opted-in via email or SMS, and then use that information to send them a welcome message through their preferred channel. Sending b oth email and SMS to ensure subscribers get NTO’s messages is not a good option, as it may annoy or spam your subscribers who only opted-in for one channel. Creating one entry source for each messaging channel is not necessary, as you can use one entry sou rce that supports both channels, such as API event or CloudPages form submit.
