Aeion Marketing + Email Provider Integration
Aeion Marketing routes email sends through a configurable provider — SendGrid, Mailgun (US/EU), Resend, Postmark, or generic SMTP (including your own mail infrastructure). One active provider per tenant, switchable in admin, with automatic retry + dead-letter queue on transient failures, domain authentication scoring (SPF/DKIM/DMARC), and webhook-driven bounce/complaint handling.

FAQ
SendGrid, built for high-volume marketing sends. Dedicated IPs and warmup are configured on the SendGrid account side, not inside Aeion.
Postmark, focused on transactional deliverability. Note: Aeion doesn't route by message priority automatically — you configure which provider is active for the tenant.
Mailgun supports a dedicated EU region endpoint, selectable when configuring the Mailgun provider record. Aeion doesn't route individual recipients by region automatically.
DKIM keys are generated and published through your ESP's dashboard, not by Aeion. Aeion's Domain Authentication check queries DNS to confirm SPF/DKIM/DMARC are in place and scores the result.
IP warmup is managed by your ESP (e.g. SendGrid dedicated IP warmup); Aeion doesn't automate this.
There's no automatic failover to a different provider. Failed sends retry against the same provider (3 attempts, exponential backoff) before landing in a dead-letter queue; switching the active provider itself is a manual admin action.
Per-event auto-classification via ESP webhooks. Per-recipient suppression. Per-tenant audit-log.
Choose the active provider per tenant based on your volume/cost profile. There's no automatic per-campaign cost-based routing.
Mailgun offers US and EU regional endpoints as a provider-record setting. There's no automatic multi-region routing across providers.
Use the SMTP provider type pointed at your own mail server. DKIM signing and data sovereignty then live on your own infrastructure.
