bitbybit vs Klaviyo
Klaviyo nurtures the people who already bought. bitbybit nurtures everyone before that — and stays with them after. The two are complements — many brands run both.
Same Shopify store, different audience.

bitbybit is the answer for the audience email CRM structurally can't reach: WhatsApp inquirers, IG DM handoffs, abandoned carts, broadcast subscribers, CTWA leads — anyone whose phone number lands in the customer record the moment they message, not at checkout. Pick bitbybit if you want a conversational customer record that begins at the first conversation, with AI agent on live Shopify catalog and broadcast / cart recovery on WhatsApp.
Pick Klaviyo if your priority is the deepest email + SMS engine on Shopify (and now a fourth WhatsApp channel inside the same platform) for nurturing the buyer list you build at checkout.
The two are complements — many high-growth Shopify brands run both: Klaviyo for the email + SMS nurture cycle on existing buyers, bitbybit for the WhatsApp audience that arrives before checkout.
Bottom line: Email and SMS CRM nurture buyers. bitbybit nurtures everyone before they become one.
Klaviyo is in marketing tools. We do both — support and marketing on one record.
Klaviyo populates the customer record from checkout data and pixel events — buyer-list shaped. bitbybit populates the customer record from the first WhatsApp conversation — pre-purchase audience shaped. Different points on the funnel, different addressable audience.
Built around the broadcast — chat marketing, email/SMS, and cart recovery. They reach and re-sell to a list, but there’s no support spine and no commerce record; the agent sees a contact, not a person.
Best for: Brands whose job is reaching a list — creator / IG funnels, email/SMS nurture, or cart recovery — with support handled somewhere else.
One AI agent that answers support and drives the repeat sale, on one customer record — built unified, with Shopify as source of truth.
Best for: D2C and Shopify brands where WhatsApp is the primary — or live — sales and retention surface.
Shopify-native email + SMS marketing CRM for post-purchase email nurture on Shopify. Added native WhatsApp as a fourth channel in late 2025.
Worth weighing
- Email and SMS lists begin at checkout — pre-purchase audience invisible to the CRM
- WhatsApp added in 2026 as a fourth channel, not the lead surface
- Mid-funnel (visitors, IG inquirers, abandoners) is only addressable via paid retargeting
- Enterprise-grade onboarding sized for the email + SMS workflow
What you get when you move from Klaviyo
The customer record begins at the first conversation, not at checkout. Pre-purchase visitors who message on WhatsApp are in your CRM the moment they raise their hand.
Keep Klaviyo for the email + SMS nurture cycle on buyers. Add bitbybit for the WhatsApp audience that arrives before checkout.
A real AI agent — not a bot that goes off-script.
The risk with AI on your store is a bot that hallucinates a price, sounds nothing like you, and torches a customer relationship. bitbybit is built so it can’t — you see it, shape it, and stay in the loop.
Preview and approve before it goes live
Build and tune your agent in the Playground against real conversations. Nothing reaches a customer until you’ve seen exactly how it answers.
It won’t guess
Outside what it knows — a price exception, a policy edge case — it says so and hands to a human with the full thread, instead of inventing an answer.
Your brand voice, locked in
Tone, rules, and what it can and can’t say are configured in AI Studio — so it sounds like your brand, not a generic chatbot.
Your data stays yours
Your customer record and conversations live in your workspace, yours to export any time, with auditable logs in AI Studio.
And every answer is grounded in your live Shopify catalog — current product, price, and stock — so it answers from your store, not the internet’s guess at your business.

Klaviyo pricing tiers by contact-list size and channel mix — see klaviyo.com/pricing. bitbybit pricing is a flat platform fee — see /pricing. WhatsApp message fees on both platforms follow Meta's published per-message rate cards; bitbybit passes those through at cost with no platform markup.
We’re not the right answer for every job.
The scenarios where Klaviyo is what you should buy. We’d rather lose the demo than waste your quarter.
- Your highest-leverage marketing job is post-purchase email + SMS nurture on the buyer list.
- You want one platform for email, SMS, push, and WhatsApp under enterprise-grade workflow tooling.
- You don't yet have meaningful pre-purchase WhatsApp conversation volume (most Shopify operators in WhatsApp-heavy markets do — see /solutions/whatsapp-marketing).

Common questions about switching from Klaviyo
Does bitbybit replace Klaviyo?
No. The two are complements — many high-growth Shopify brands run both. Klaviyo handles the email + SMS nurture cycle on the buyer list. bitbybit handles the WhatsApp audience — pre-purchase visitors, IG DM handoffs, abandoned carts, broadcast subscribers — most of whom never end up on the email list.
What's the difference between Klaviyo's new WhatsApp channel and bitbybit?
Klaviyo added WhatsApp in late 2025 as a fourth channel in an email-first platform — fine for sending WhatsApp messages to your existing email list. bitbybit is shaped around the WhatsApp thread from day one: AI agent on live Shopify catalog, in-thread cart and payment, and a customer record that begins at the first conversation rather than at checkout.
