The Two-Vendor Problem

Stop managing split email services

Many SaaS teams start with Loops for product onboarding loops, then quickly realize they still need Resend or Postmark for auth emails, invoices, and transactional webhooks. Reloop unifies both under one API key.

Fragmented Stack (Loops + 2nd API)
  • ✕ Loops → Onboarding & Newsletters
  • ✕ Resend / Postmark → Auth & Receipts

Contact Penalty vs Send Pricing

Why pay for inactive contacts?

Loops increases your monthly bill whenever your contact list grows. Reloop charges only for emails actually sent.
