Lookups can help you maintain a clean, compliant mobile database, with the added bonus of helping you save money by cleaning up invalid and inactive numbers. Get information about any phone number from any country in seconds to help understand the reachability of your audience and the potential effectiveness of your campaign.

Why use Lookups?

Becoming more acquainted with your customer contact database provides a range of benefits. In addition to simply avoiding messaging costs to invalid numbers, lookups help locate numbers that are no longer associated with a subscription, indicating the previous recipient is no longer using the number.

Where urgent communication is required, outbound messages can be delayed due to the recipient’s device being out of range or powered off. Find out whether the device is active or temporarily absent from the network to better inform your business process.

Whether it’s cleansing numbers as you’re accepting them into your database, or running a periodic check to remain spam-compliant, MessageMedia makes it easy to get closer to your customer data.
