The stack, top to bottom
Every store has the same six layers in the recovery stack. Our picks for each in 2026:
- Checkout. Shopify Pay (native), Shop Pay Installments, Klarna for high-AOV
- Email + SMS recovery. Klaviyo (alt: Omnisend for SMB, Mailchimp for very early)
- Voice + Email recovery. Callsy
- Push notifications. Onesignal or skip
- Attribution. Triple Whale or Northbeam
- Reviews + UGC. Loox, Yotpo, or Junip
Why this stack, not the other one
Three principles guided the picks:
- Specialist > generalist. Best email tool, best voice tool, best attribution tool. Avoid 'all-in-one' platforms that do everything mediocrely.
- Native first. Shopify-native apps (Klaviyo, Callsy, Loox) over third-party glue that breaks at scale.
- Don't double-pay for the same channel. Pick one email/SMS tool, not two.
What to install in what order
If you're starting from zero, install in this order to maximize early ROI:
- Week 1. Klaviyo (email + SMS abandoned cart flows)
- Week 2. Callsy (voice + email as the first touch in your flow)
- Week 4. Reviews tool (Loox/Yotpo) for social proof in recovery emails
- Week 6. Triple Whale for clean attribution across all channels
- Week 8. Skip the rest until something specific is broken
What to skip in 2026
Three categories of recovery tooling we don't recommend in 2026:
- Generic chatbots without voice. Text-only support tools rarely move recovery metrics
- Browser push (for most categories). 1–3% recovery, high opt-in friction, low signal
- Standalone exit-intent popups. Convert short-term but tank brand and email quality long-term
What this stack costs
Approximate monthly cost for a mid-sized Shopify store doing €50K–200K MRR:
- Shopify (Advanced). $399/mo
- Klaviyo (mid-tier). $200–400/mo
- Callsy (Pro). €99/mo
- Triple Whale. $150–300/mo
- Loox/Yotpo. $30–100/mo
- Total. ~$900–1,300/mo for a stack recovering 25–40% of carts vs 5–8% baseline
