A useful bulk SMS sheet usually contains first name, phone number, message, consent status, and send status. Keeping message content in its own column makes personalization and review much easier before dispatch.

How to reduce failed messages
Use E.164-style numbers, such as +447123456789, remove duplicate contacts, check SMS character counts, and do not send to people who have not opted in. Start with a small test batch when changing a message or destination country.
