SMS can reach customers quickly, but the channel depends on explicit permission, accurate identity, reasonable frequency and an easy way to stop messages. Choose a platform for your countries, message types, ecommerce system and compliance workflow.

Common questions
Can I text existing customers without a new opt-in?
Do not assume a purchase grants marketing permission. Take advice for the countries you serve and use a recorded consent process.
Should SMS replace email?
Usually not. SMS suits urgent or concise messages, while email carries richer detail and is easier to archive.
What should an SMS report include?
Delivery, failure, clicks where appropriate, replies, opt-outs, conversion, complaint signals, cost and the original consent source.
