Is your sending domain configured correctly?
Check its published SPF and DMARC records for free. No account or email address required. The lookup highlights missing and duplicate policies and explains what to investigate next.
Email intelligence with a little magic — and a lot of control.
Parcel Wing gives every send a visible trail: authentication, routing, delivery, bounces, complaints, opens, clicks, unsubscribes, and reputation impact — with guidance before small problems become sending disasters.
Reputation guards
Detect risky sending patterns, bounce pressure, complaints, and unhealthy domains before they damage your ability to reach the inbox.
Lifecycle analytics
See the full path from send to delivery to engagement, including bounces, complaints, opens, clicks, unsubscribes, and provider-level deliverability signals.
Human-friendly automation
Build broadcasts, audience segments, lifecycle automations, and preference-aware campaigns without needing an engineer for every change.
What AI-native means for email.
Not a vanity chatbot bolted onto an old ESP. AI-native means the platform understands the sending lifecycle well enough to explain, warn, recommend, and protect.
Reputation copilots
Turn bounce pressure, complaint spikes, suppression events, and domain health into practical recommendations.
Lifecycle context
Reason across domain setup, IP route, send event, provider response, recipient engagement, and future reputation impact.
Guardrails before growth
Warn, throttle, suppress, or pause risky sending patterns before a campaign quietly harms future inbox placement.
Operators + developers
Developers get API, SMTP, webhooks, and logs. Marketing teams get broadcasts, audiences, automations, analytics, and explainable insights.
Every message gets a flight path.
Email deliverability can feel like a dark art. Parcel Wing turns it into a visible, guided system for every transactional send, campaign, and lifecycle automation.
Authenticate the sender
SPF, DKIM, DMARC, bounce handling, and tracking domains are guided from day one.
Guard the launch
Check domains, IP reputation, bounce risk, and list quality before volume scales.
Watch the flight
Track delivery, delays, bounces, complaints, opens, clicks, unsubscribes, and webhooks from one dashboard.
Improve the next send
Use guided recommendations to throttle, suppress bad addresses, clean lists, and protect future inbox placement.
Built for real email pain
Stop guessing why your messages disappeared.
“Why did this customer never get their receipt?”
Trace the message from API request to delivery event, bounce, suppression, or provider response.
“Which campaign actually moved people?”
Compare broadcasts by opens, clicks, unsubscribes, complaints, bounce rate, and engagement quality.
“Is my list hurting my domain?”
Spot hard bounces, complaint patterns, stale segments, and risky sources before reputation suffers.
“Can my team run campaigns without engineering?”
Build broadcasts, segments, topics, templates, and lifecycle automations in a dashboard made for operators.
Not another black-box ESP.
Parcel Wing is built for teams that want simple sending, but also want to understand and improve the path every email takes. From transactional receipts to marketing journeys, your dashboard shows what happened, why it happened, and what to fix next.
