This is the exact SMS opt-in a shopper sees at checkout on a Salesreach-enabled Shopify store — Shopify's own native "Text me with news and offers" checkbox, next to the phone number field.
Default state — unchecked, no phone field or SMS disclosure shown yet. The shopper must actively check this box; Salesreach never enables it on their behalf:

After the shopper checks the box — a phone number field and the full consent disclosure appear, including the Privacy Policy and Terms of Service links Shopify renders directly in the disclosure text:

"By signing up via text, you agree to receive recurring automated marketing messages, including cart reminders, at the phone number provided. Consent is not a condition of purchase. Reply STOP to unsubscribe. Reply HELP for help. Message frequency varies. Msg & data rates may apply. View our Privacy policy and Terms of service."
This disclosure is Shopify's fixed checkout copy. Salesreach uses current SMS marketing consent for checkout recovery and post-purchase messages, as described below.
Salesreach only messages a shopper whose SMS marketing consent in Shopify is Subscribed. This checkout checkbox is the main way that happens; a shopper can also subscribe through the merchant's other Shopify consent flows, such as a storefront signup form or their customer account. Salesreach reads that status from Shopify and re-checks it right before every message. It never purchases or imports phone number lists, never sets consent itself, never checks the box on a shopper's behalf, and has no opt-in form of its own. Full Privacy Policy and Terms of Service govern every message described below. A shopper who is not subscribed in Shopify is never messaged.
By checking this box on any Salesreach-enabled store's checkout, a shopper is agreeing to receive SMS marketing messages sent by Salesreach (operated by Revotech OÜ) on that merchant's behalf, at the phone number provided — the identity of the actual sender for every message described on this page.
Checkout recovery: one message after at least an hour of checkout inactivity, offering help and a link to continue the checkout. Salesreach checks that the checkout remains incomplete, the shopper has not placed another order, the items are available, and SMS marketing consent is still active before sending. Messages are sent during supported recipient daytime hours and share a limit of one proactive message per shopper per store in 24 hours.
Post-purchase cross-sell: a message scheduled 12-24 hours after a completed order, offering help with a relevant next purchase. Welcome discounts are limited to eligible first-order shoppers. All messages are triggered by the shopper's activity with that merchant.
Sample message:
Reply STOP at any time to unsubscribe. Replying STOP to any message unsubscribes the shopper from further messages immediately, in any language, matching the disclosure shown at signup.
