What is the best email platform for DTC brands?
Short answer: Klaviyo (depth + ecommerce integration), Postscript (SMS), Customer.io (sophistication). Pick by stage + integration stack.
Full answer
DTC email platform choice depends on stage + integration stack:
Pre-$1M revenue: Klaviyo. Native Shopify integration, every standard ecommerce flow ships out of the box.
$1M-$10M: Klaviyo + Postscript (SMS) is the dominant combo. Add Attentive if SMS is the primary channel.
$10M+: consider migrating to a more flexible platform (Customer.io, Iterable, Braze) when segmentation gets complex.
The platform is rarely the leak. The flows + segmentation + content cadence are. Most under-$5M brands could 2x their email revenue staying on Klaviyo and fixing the operational layer — not switching platforms.
