Frequently Asked Questions
Everything technical leaders ask when migrating production dispatches.
How does JioCoder achieve 99.8% primary inbox placement?
We isolate every tenant into rigorously warmed, dedicated IP clusters. Our proprietary reputation router performs proactive DNS alignment checks (SPF, DKIM 2048-bit, DMARC reject mode, and BIMI) before releasing any SMTP handshakes, preventing cold-reputation flags.
Can we dispatch raw JSON streams directly from our backend?
Yes. You can stream recipient arrays directly via our REST or gRPC endpoints. The engine handles JSON streaming decoding, automatically binds deep variables against your predefined HTML templates, and serializes payloads in microsecond increments.
What happens if a recipient mail exchange rejects a message with 4xx or 5xx codes?
Soft bounces (4xx rate-limits, graylisting) trigger exponential backoff auto-retries across separate fallback IPs without duplicating sends. Hard bounces (5xx invalid recipient) are immediately isolated into a tenant-specific suppression table to protect sender scoring.
Is there a free tier for staging and dev sandboxes?
Every team gets 10,000 free live test emails per month forever with full access to sandbox simulators, JSON payload validators, and webhook receivers. No credit card required.
