About HeySunday
HeySunday sells plastic-free cleaning supplies for the laundry room and kitchen, from detergent and dryer sheets to washing machine cleaner, wool dryer balls, dishwasher sheets and reusable paper towels.
Every order ships free within the US, so the real decision is a one-time order or a subscription that renews every 30 or 60 days.
HeySunday is run by Mechanism LLC, which lists an address in Claymont, Delaware. Its laundry detergent sheets are sold as biodegradable, vegan and cruelty-free, with no dyes, and a pack of 60 sheets comes in a flat envelope rather than a jug; the brand says every pack goes through third-party testing. The washing machine cleaner comes as 24 tablets, which HeySunday pitches as a year's supply.
Outside the shop, the company runs a donation program that gives loads of laundry to families through partner organizations, and it funds the Green Minds Scholarship, a $2,500 award for high school seniors and undergraduates in environmental science, sustainability or related fields, applied for through Bold.org. Customer support answers Monday to Friday, 8 AM to 5 PM Eastern, and a blog covers laundry and cleaning advice.

How to use a HeySunday discount code
- HeySunday takes codes in the promo code field during checkout.
- If a friend referred you, the $10 credit is already saved to your cart, so check the total before typing another code over it.
- HeySunday doesn't say whether the two combine.
- Picking Subscribe & Save changes the order as well, though the page doesn't state what that saving is.
- Bundles and multi-item orders may arrive in separate packages, so one box turning up first doesn't mean something is missing.
More ways to save at HeySunday
- The guarantee is the safety net at HeySunday: your first order of each product, up to two units, can come back for a full refund.
- Subscribers protect their money by managing renewals, skipping or canceling in the customer portal before an order processes, because processed repeat orders can't be refunded.
- Sending a referral link puts $10 in a friend's cart.
- Students in environmental science or sustainability can also apply for HeySunday's $2,500 scholarship, which isn't a discount but is real money toward school.
