Mailchimp nurtures the people on your email list. bitbybit nurtures the WhatsApp audience that arrives before they're on it. Most brands run both.
Same Shopify store, different audience.
bitbybit is the answer for the WhatsApp audience email lists structurally can't reach: IG DM handoffs, abandoned carts, broadcast subscribers, CTWA leads — most of whom never end up on the email list. Pick bitbybit if you want a conversational customer record that begins at the first conversation, with AI agent on live Shopify catalog and cart recovery / broadcast on WhatsApp.
Pick Mailchimp if email is your highest-leverage marketing channel and you want a mature drag-and-drop automation platform with broad SMB reach.
Most Shopify brands run both: Mailchimp for the email nurture cycle on subscribers, bitbybit for the WhatsApp audience that arrives before they sign up.
Bottom line: Email nurtures the people on your list. bitbybit nurtures everyone before they get on it.
Mailchimp's customer record is populated by opt-in forms, checkout, and email lists. bitbybit's customer record is populated by the first WhatsApp conversation. Different surfaces, 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.
The brand-name SMB email marketing standard. Mature drag-and-drop automation, broad small-business reach, deep template library. Email-first by design.
The customer record begins at the first conversation, not at the first opt-in. Pre-purchase visitors who message on WhatsApp are in your CRM the moment they raise their hand.
Keep Mailchimp for the email nurture cycle on your subscribers. Add bitbybit for the WhatsApp audience that arrives before they sign up.
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.
Build and tune your agent in the Playground against real conversations. Nothing reaches a customer until you’ve seen exactly how it answers.
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.
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 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.
Rows are value-framed (what changes in your operation), not feature-framed. The "so what" column is the question your CFO will ask anyway.

No. Most Shopify brands run both. Mailchimp handles the email nurture cycle on your subscriber 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.
Both connect to Shopify, so customer records stay consistent on the commerce side. Email and WhatsApp campaigns then run in parallel against the same underlying customer data.

We handle the WhatsApp Business API number transfer between BSPs. Typical timeline: 1–3 days. Zero downtime — your customers keep messaging the same number.
