Reloop vs Loops
Loops is built for SaaS lifecycle email—onboarding, updates, and newsletters with a polished marketer UI. Reloop covers that surface plus transactional API, SMTP, and self-hosting.
Loops found a niche: founders and growth teams at SaaS companies who want beautiful product email without learning Mailchimp. The editor is fast, the brand is modern, and the mental model is audience → loop → send.
The gap appears when engineering needs password resets, billing receipts, and webhook-driven sends at the same domains and reputation pool. Many Loops customers add Resend or Postmark beside it. Reloop is for teams that want product email and transactional infrastructure together—with APIs their backend already understands.
The two-vendor problem
What Loops + transactional API stacks look like in practice.
// Typical SaaS email stack today
Loops → onboarding & newsletters
Resend / Postmark → auth emails & receipts
Stripe → billing events → second API client
Reloop → all of the above, one API key

Consolidating Loops + transactional
How teams unify without losing lifecycle automations.
- Export Loops audiences and recreate segments in Reloop contacts—with API sync from your product database going forward.
- Rebuild onboarding loops as Reloop campaigns triggered by product events (signup, trial end, feature activation).
- Point auth and billing services at Reloop's transactional endpoint; delete the secondary API vendor.
- Use one set of domain authentication records and one deliverability reputation pool.
