Retainful

The Retainful loyalty integration for Shopify. Cart recovery emails that know what the customer has earned.

Integrations Email and SMS

Retainful and Yuko

Retainful recovers abandoned carts and runs lifecycle email. Yuko sends it your customer and loyalty data. A recovery email can then name what the customer already has waiting.

How the Retainful loyalty integration works

  • Sends Yuko customer attributes into Retainful, including points balance and VIP level, plus 25 loyalty events.
  • Lets you personalise a recovery email with the points a customer has, or the points this cart would earn.
  • Lets you filter a campaign by level, so a Gold customer's abandoned cart gets different treatment from a first-timer's.

The sync runs one way, from Yuko into Retainful.

What Yuko sends to Retainful

Customer attributes for filtering and personalisation, plus the same 25 loyalty events every other Yuko connector carries.

  • Points balance
  • VIP level
  • Customer identity: email, name and the Shopify customer ID

Loyalty events

Twenty-five events, the same catalogue the Klaviyo and Omnisend connectors use. Every connector draws from one shared event list.

  • Joined loyalty program
  • Earn points
  • Redeem points
  • Points adjusted
  • Points expired
  • Points expiring reminder
  • Reward expiry reminder
  • Birthday reminder
  • Anniversary reminder
  • VIP tier entry
  • VIP tier upgrade
  • VIP tier downgrade
  • VIP tier retained
  • VIP tier retention warning
  • VIP milestone nudge
  • Referrer welcome
  • Friend reward unlocked
  • Referral completed
  • Referrer rewarded
  • Membership subscribed
  • Membership upgraded
  • Membership downgraded
  • Membership paused
  • Membership cancelled
  • Membership reactivated

You choose which of these Yuko forwards.

What you can build with it

Retainful already sends the cart email. The loyalty attributes decide what it can say.

Cart recovery

Name the points sitting in their account

The recovery email already goes out. The points balance lets it name what the customer has waiting, instead of only showing the cart again.

“Your cart is still here, and so are your 480 points. That is $9 off if you finish today.”

Why it works: it adds a reason to come back that the cart alone does not give.

Campaign

Treat a Gold customer's cart differently

Filter a campaign on the VIP level attribute, so your best customers get a different sequence from a first-time buyer.

“As a Gold member you already have free shipping on this order. It is waiting whenever you are.”

Why it works: discounting a loyal customer gives away margin you did not need to spend.

Do not duplicate

Keep loyalty emails in one place

Retainful can send loyalty emails using the attributes, and so can Yuko. Running both means customers get everything twice.

“Retainful for cart abandonment. Yuko workflows for points reminders and level changes.”

Why it matters: duplicate sends are the most common problem after connecting a second tool.

Installing the Retainful loyalty integration

Get your API key from your Retainful account. In your Shopify admin, go to Apps → Yuko Loyalty → Integrations → Retainful and paste it. Customer attributes flow into Retainful from that point.

Divide the work. Use Retainful for cart abandonment and lifecycle email. Use Yuko workflows for loyalty messages such as points reminders and level changes. Do not run the same automation in both.
