Resend or Sendora — pick the trade-off, not the marketing.
Resend nailed developer-first transactional email — React Email templates, dashboard, audit logs, audiences. Sendora uses Resend Domains under the hood for BYOD verification + wraps the rest of the lifecycle layer (audiences via Customers, journeys via Automation, attribution via Links, support cross-link via Support). If you only need transactional, Resend wins on DX polish; if you need the lifecycle layer too, Sendora bundles.
Modern developer-first transactional email API. Beautiful DX. Standalone — no lifecycle / audience / support layer.
Resend-grade transactional email + the lifecycle automation + audience targeting + support inbox + auth all in one tenant.

Why teams switch to Sendora
- You're using Resend + Customer.io / Loops / Knock + Segment — Sendora collapses all four.
- Lifecycle messaging on the same `userId` + same audience as transactional sends.
- BYOD goes through the same Resend Domains integration Sendora already uses (we don't reinvent the verification flow).
When Resend is the right call
- You need React Email's component-based template authoring — Sendora has `{{var}}` regex interpolation only.
- You need Resend Audiences Broadcast's single-call list send — Sendora fans out per-recipient via Automation.
- Pure transactional, no lifecycle needed — Resend's DX is best-in-class and Pro $20/mo is hard to beat.
- Your team has standardised on Resend's audit log + Inbox Studio for ops workflows.
BYOD email with real Resend Domains verification + content scanner + probation + recipient-dedup + Wave 1a consent gate. Same SDK as Push + SMS.
Resend ships transactional, Customer.io ships lifecycle, Mailchimp ships broadcasts — three vendors, three reputations, three audience exports. Sendora collapses senders: one BYOD setup, real Resend Domains verification (not optimistic stubs), DKIM signed by you, recipient-dedup at the dispatch layer (no duplicate sends after a signin), per-org rate limits + 30-day probation pool, signed bounce/complaint webhooks, RFC 8058 one-click unsubscribe, opt-in consent enforcement on broadcast + workflow categories (Wave 1a). Honest about audience fan-out: `sendEmail` takes one recipient at a time — audience-driven fan-out happens via Automation workflows or your own iteration, not a single-call audience send.
