Should I use Klaviyo or a WhatsApp-first tool like Interakt, AiSensy or WATI for marketing?
It's not either/or - most serious Indian D2C brands run Klaviyo for email, still the strongest cart-recovery and flow engine, alongside a WhatsApp Business API tool for the channel Indian customers actually open. Pick Interakt if you want the deepest native Shopify triggers for cart abandonment and order updates, AiSensy if you're price-sensitive and running broadcast-heavy campaigns, or WATI if you need a CRM-grade agent inbox with Zoho/HubSpot sync. The catch with Klaviyo is USD billing that climbs fast past roughly 50K contacts, so budget for that curve or plan to pair it with a leaner setup as your list grows - and never broadcast on WhatsApp to non-opted-in numbers, Meta will shut the number down.

The clearest head-to-head of the three tools every Indian D2C founder ends up comparing - Shopify integration depth, CRM connectors, pricing and support - with a clean 'pick this if' framework instead of a vague feature table.
A straightforward side-by-side of the Indian WhatsApp Business API providers (AiSensy, Interakt, WATI, Gupshup, and more) so you're not picking blind between near-identical pricing pages.
A practical, screen-recorded walkthrough of actually wiring WhatsApp into a Shopify store, which matters because WhatsApp is the channel Indian D2C customers respond to most - the how-to companion to the WATI/Interakt/AiSensy comparisons in this category.
