One email. SmartLink CTA. Email subscribers tap, opt into SMS, OTTO qualifies. They move from a channel with 20% open rates to one with 98%. Their contact record gets the phone number added. Attribution links the SMS opt-in back to the email campaign that drove it. Your list doesn’t shrink — it upgrades.
Email subscribers who opted in already demonstrated interest. They know your brand. But email competes with hundreds of other messages in an inbox designed for managing volume. SMS is personal — it’s the same channel as a text from a friend or family member. Your email subscribers who convert to SMS will have dramatically higher engagement rates, response rates, and lifetime value. The conversion campaign pays for itself in the first send to the new SMS segment.

Add a SmartLink button to any email — your newsletter, a promotional send, a transactional follow-up, or a standalone upgrade campaign. The button copy can be as simple as “Get SMS-only updates” or tied to an offer: “Text for 20% off your next order.” Mobile email readers tap the button and go directly to the Messages app. Desktop readers see the QR bridge. Attribution is captured at the link load event — which email, which campaign, which list segment drove the tap.

If you’re using a CRM, the phone number can be added to their existing contact record. Critically — converting to SMS doesn’t require removing them from email. You now have two active channels for the same contact: email for long-form content, SMS for time-sensitive offers, alerts, and conversations. The contacts who upgrade to SMS will be your highest-converting segment on both channels. You don’t replace email. You convert it into a higher-response channel.
