FAQ
›Is Postmark or Loops cheaper?
Postmark starts at $15/mo, Loops starts at $49/mo — Postmark wins on entry pricing. But entry pricing is rarely your real cost; check our pricing-curve modelling on each tool's review page for ARR projections.
›When should I pick Postmark over Loops?
Both compete in the same communication space. Pick Postmark if your stack is closer to its native integrations, your team already uses sister products from the same vendor, or its regional coverage matches your customer base. Pick Loops for the inverse.
›Can I migrate from Postmark to Loops later?
Most modern SaaS supports CSV/JSON export for the core data model. The migration cost is integration work — every Zapier workflow, every webhook URL, every API token has to be re-wired. Budget 2-4 weeks of engineering time for a non-trivial production migration.
