Klaviyo: not the right pick when sub-$10k/mo stores where mailchimp or omnisend save 60% of the bill.. Postscript: not the right pick when sub-$20k mrr stores — fixed cost overweights revenue at this scale..

Klaviyo

Pros

  • Best-in-class Shopify-native integration
  • Segmentation depth nothing else matches at this price tier
  • Predictive analytics that earn back their cost past $50k MRR
  • Reliable deliverability with shared and dedicated IPs

Cons

  • Pricing scales aggressively past 50k contacts
  • Email builder still feels dated next to Postscript / Omnisend

Postscript

Pros

  • Specialist focus — SMS gets the attention it deserves
  • Conversational AI/human hybrid drives real AOV lifts
  • Tight Shopify + Klaviyo integration

Cons

  • Pricing not friendly under $20k MRR
  • Email features absent — you need Klaviyo/Omnisend alongside
  • SMS regulation overhead (TCPA, A2P 10DLC) is real and not trivial
