The messages that bringcustomers back.
Most stores send a welcome email and nothing else. The revenue is in the flows: the cart left at midnight, the second order at day 30, the review request that lands after delivery. We build them, on email and on WhatsApp, and report what each one earns.

In short
Byteinfy sets up email and WhatsApp marketing automation for Shopify from $1,000: abandoned cart, post-purchase, win-back and review flows on Klaviyo, Shopify Email or the WhatsApp Business API, with the tracking to prove revenue per flow.
Last updated 5 September 2026 · Written by the Byteinfy team, which builds and operates SwipeReel and myBillPlease.
Who it is for
- Stores with a list and no flows
- Indian brands where WhatsApp converts better than email
- Brands paying for traffic and losing repeat orders
- Teams that want automation without a full-time marketer
What you get
- Core flows: welcome, abandoned cart and checkout, post-purchase, win-back, review request, back in stock
- WhatsApp Business API setup with approved templates and opt-in handling
- Segmentation from Shopify data: first-time, repeat, high value, at risk
- Revenue attribution per flow in Klaviyo or GA4
- Templates in your brand, written for the channel
How it works
- 1
Audit
What is sending today, what it earns, and what the list looks like.
- 2
Build
Flows, templates and segments, reviewed on test accounts before anyone real gets a message.
- 3

Monthly read of revenue per flow, then adjustments.
Pricing
From $1,000
Flow setup on one channel is $1,000 to $2,500. Ongoing campaign and flow management is a monthly retainer.
Questions we get asked
- Which platform do you recommend?
- Klaviyo for stores that will invest in email; Shopify Email for simple needs; WhatsApp Business API through a provider like Interakt or Gallabox for Indian audiences. We set up what fits, not what pays us.
- Is WhatsApp marketing allowed?
- Yes, with opt-in and approved templates. We handle both so you stay inside Meta's rules.
