Features & Product Roadmap
We believe in complete transparency. Below is an exhaustive breakdown of our currently operational infrastructure alongside capabilities undergoing active engineering development.
1. Professional Inbox & Domain Mailboxes
Clean, human-friendly mailbox management allowing team members to communicate using official organizational domains.
Multi-Domain Organization
Manage multiple sending domains under a single unified organizational dashboard without siloed configurations.
- Parent & Subdomain isolation
- Custom sender aliases
- Unified activity stream
Role-Based Team Access
Granular permission management allowing distinct capabilities for Owners, Administrators, and Mailbox Members.
- Scoped permission checks
- Secure invite system
- Audit logging
Custom Mailbox Tagging & Search
Full-text search across message headers and recipient metadata, combined with customizable category tagging.
- Header indexing
- Thread grouping
- Filter rules
2. Transactional Email Delivery Engine
Built upon Amazon Simple Email Service (SES) to provide industrial-grade delivery for application verification codes, password resets, and critical alerts.
Amazon SES v2 Cloud Transport
Direct integration with Amazon SES v2 SendEmail API with SigV4 request authentication. Outbound sending is verified in AWS Sandbox; production-scale volume access is currently under review.
- AWS SigV4 Authentication
- Amazon SES v2 API
- ap-south-1 regional routing
- SES Sandbox Verified
Idempotency & Retry Architecture
Client-provided idempotency keys prevent duplicate dispatches during transient network timeouts or client retries.
- Idempotency cache
- Exponential backoff
- Dead-letter logging
Multi-Region Transport Failover
Automatic failover to secondary AWS SES regional endpoints in the event of upstream regional degradation.
- Health probing
- Secondary identity syncing
- Zero-downtime routing
3. Domain Authentication & DNS Setup Assistance
Eliminate manual DNS misconfigurations. PlusMail provides guided instruction and automated Cloudflare DNS synchronization for complete cryptographic alignment.
Automated DKIM Key Generation
Provisions 3 distinct 2048-bit DKIM tokens for every verified domain to ensure rotating cryptographic authenticity.
- 2048-bit RSA keys
- 3-token Easy DKIM
- Automatic CNAME verification
Automated Cloudflare DNS Provisioning
One-click programmatic DNS provisioning for Cloudflare-managed domains, eliminating manual record copying.
- Zone-level CNAME/TXT creation
- Conflict prevention
- Instant propagation validation
DMARC Policy Advisory
Guides domain administrators through gradual DMARC enforcement: from p=none (reporting) to p=quarantine and p=reject.
- DMARC syntax validator
- Aggregate RUA report parser
- Alignment failure warnings
4. Email APIs & Integration Surface
Programmatic email dispatch engineered for modern web backends, microservices, and serverless edge functions.
Hono-Based Microservice API
Modular microservices running on Cloudflare Workers and Node.js runtimes with standardized JSON responses.
- JWT session auth
- Bearer API token support
- OpenAPI schema ready
Outbound SMTP Relay
Standard SMTP credentials for legacy application backends, WordPress, and existing notification tools.
- TLS 1.3 encryption
- Port 587 submission
- Per-service credentials
Official Client SDKs
Type-safe SDKs for TypeScript, Node.js, Python, and Go with built-in retries and TypeScript autocomplete.
- npm @plusmail/sdk
- Python pip plusmail
- Go client package
5. Delivery Event Monitoring & Reputation Protection
Proactive monitoring and automated suppression mechanisms that safeguard domain reputation and enforce compliance with global anti-spam regulations.
Automated Bounce Suppression
Architecture designed to process Amazon SES SNS bounce webhooks, recording permanent 5xx failures to tenant suppression tables.
- Automatic recipient blocking
- Bounce diagnostic reason logs
- Reputation score tracking
Complaint & Feedback Loop Hook
Spam complaint notifications from mailbox providers automatically suppress future dispatch and flag the account for review.
- FBL integration
- Zero tolerance enforcement
- Audit log generation
Real-Time Webhook Notifications
Custom webhook endpoints receive instant JSON notifications when emails are delivered, opened, bounced, or flagged.
- HMAC signed payloads
- Custom webhook retry logic
- Event delivery logs
