Aeion Notifications for Transactional SaaS

Transactional notifications drive activation (welcome flows), retention (re-engagement), revenue (cart recovery), and trust (security alerts). Most SaaS teams duct-tape SendGrid + Twilio + Pusher + Customer.io across 3-6 vendors costing $20K-200K+/year for mid-size workloads — plus the engineering tax of keeping templates, preferences, and unsubscribe handling in sync across silos. Aeion Notifications bundles email + SMS + push + in-app + 24 built-in transactional handlers + user preference center natively.

FAQ

Identical. Aeion routes through SendGrid (or whichever provider). Aeion is the orchestrator; provider is the relay. Per-tenant DKIM/SPF/DMARC.

Per-tenant template library. Per-template version history. Per-template A/B variants.

Per-user preference graph. Per-category opt-out. Per-channel opt-out. Per-link RFC 8058 one-click.

Per-user timezone + start/end. Per-priority bypass (urgent always sends). Per-event configurable.

Per-user max-per-hour + max-per-day. Per-category override. Per-cap consolidate-to-digest option.

Per-event template variants. Per-variant tracking. Per-winner auto-promotion — included free.

Native via webhook channel. Per-tenant webhook registry. Per-webhook signed payload.

Each channel is configured with the provider you choose (email: Resend or SendGrid; SMS: Twilio, Plivo, Vonage, or AWS SNS). Failed deliveries retry with exponential backoff (5 attempts) against that same provider and land in a dead-letter queue for visibility if they still fail — there's no automatic cross-provider failover today.

Customer.io: $0.10-1.00/MAU. For 50K users: $5K-50K/month. Aeion: included free + provider passthrough. 70-90% savings typical.
