About iFilters

iFilters sells water filtration systems and replacement filters online for homes and businesses: whole-house systems, reverse osmosis and drinking water systems, water softeners, replacement cartridges, membranes and parts, under brands including iFilters, Pro+Aqua, Hydronix and Hydroguard. It offers free shipping on systems and filters and 30-day free returns.

Challenge

Replacement filters need reordering on a schedule, so email should be one of iFilters' strongest sales channels. Its campaigns went to the whole list in four-email bursts around each holiday and were averaging open rates of about 21% and click rates under 1%. iFilters brought in SmartSites to redesign its campaigns in Klaviyo, grow the list and build automated flows.

How we helped iFilters.

Email & SMS

SmartSites lifts email engagement for a water filtration retailer

SmartSites runs iFilters' email marketing in Klaviyo on its Shopify store: engaged-audience campaigns planned with the iFilters team, new sign-up forms and automated flows.

  • Engaged Audiences: Sends each campaign to subscribers who are likely to open, instead of mailing the whole list several times per holiday.
  • Campaign Calendar: Plans newsletters, product highlights and sales with the iFilters team, from a back-to-school newsletter to a four-email Labor Day sale.
  • Product Education: Features whole-house systems, drinking water systems, best sellers and replacement filters and cartridges, so customers find the right system and reorder the right filter.
  • New Sign-Up Forms: Launched mobile and desktop pop-ups and exit-intent forms, several with an SMS opt-in, plus a pop-up that collects shopper details.
  • Testing: Runs A/B tests on campaigns and applies what wins to the next sends.
  • 113% Increase in email open rate
  • 276% Increase in email click rate
  • 240% Increase in revenue per email sent
  • 185% Increase in placed order rate
Each campaign now earns more than before while going to fewer than half as many people, with revenue per email sent up 240%.
