The program, in full

• Who texts you: Sunday, a product of Modern Matter LTD, on its own behalf. Every text is Sunday's own recommendation, never a message sent for a brand, and the list of people who sign up is never shared with or sold to brands.
• What you get: outfit recommendations, with the price of each piece and a link to buy it from the brand, and replies when you text Sunday.
• How often: message frequency varies: up to three outfit drops a week, plus replies whenever you text Sunday.
• What it costs: Sunday is free. Message and data rates may apply, depending on your mobile plan.
• To stop: reply STOP to any message (CANCEL, END, QUIT, UNSUBSCRIBE, REVOKE and OPT OUT work too), or email hello@sunday.fit. After a STOP you'll get one last text confirming you're unsubscribed, and nothing after that. Text START to join again.
• For help: reply HELP to any message, or email hello@sunday.fit.
• Delivery: mobile carriers are not liable for delayed or undelivered messages.
• Who can sign up: the subscriber or regular user of a US mobile number, aged 16 or over.
• Your number: used to send you Sunday's texts, answer yours, and keep a record that you asked for them. No mobile information will be shared with third parties or affiliates for marketing or promotional purposes. The details are in the privacy policy.
• Changes: if these program terms change in a way that matters, we'll tell you by text before the change applies.
• Not required: texts are optional. Sunday also works in WhatsApp, and you never need to sign up here to use it or to buy anything.
