Clean Shopify Customers in two minutes
Your Shopify customer list powers promotions, abandoned-cart flows, and win-back emails — and a decayed list quietly hurts the deliverability of all three. Cleaning customer emails and phones keeps your store's marketing landing in the inbox and your SMS reaching real mobiles.
What's hiding in your list
Guest-checkout and one-time buyers leave behind addresses that go stale fast, dragging down the deliverability of your promotional sends.
Customers sometimes mistype their email at checkout, which means order and marketing emails bounce and support tickets follow.
SMS marketing to an unvalidated phone list wastes spend on landlines, disconnected numbers and VoIP entries.

Will this improve my email and SMS results?
