Should I use Klaviyo, WebEngage, MoEngage, or something else for email and retention marketing?
The short answer
If you're on Shopify and email/SMS is 80% of your retention game, start with Klaviyo, it has the deepest e-commerce integration and the ecosystem (agencies, templates, benchmarks) is built around it, though pricing climbs fast past ~50k contacts. If you need one stack across email, SMS, WhatsApp, push and in-app messaging, especially once you have an app, WebEngage and MoEngage (both built in India, both used by Indian D2C majors and unicorns) are the stronger full-funnel bet and usually cheaper at scale on Indian contact volumes. Don't buy a ₹15k/month platform on day one; run 90 days on Klaviyo's free tier or even Mailchimp before you know what you actually need.
