Newsletter Email Delivery

Last updated: 2026-05-15

​
Current Model

Newsletter delivery uses a multi-provider architecture.
  • packages/backend/src/newsletter-email.ts defines the shared provider interface and provider implementations.
  • newsletter_email_provider_settings stores the active provider.
  • newsletter_email_provider_credentials stores encrypted provider credentials.
  • apps/api and apps/schedule-worker both resolve the active provider at send time through the shared backend services.
  • Provider credentials should be managed through Admin Settings, not through provider-specific environment variables.
Supported provider implementations currently exist for:
  • Amazon SES
  • SendGrid
  • Elastic Email

​
Current Production Choice

The active production provider is Elastic Email. The platform sending domain is: 
mail.getmaito.com
Default sender addresses remain: 
send@mail.getmaito.com
notifications@mail.getmaito.com

​
Current Elastic Email DNS

These records are active in the getmaito.com Cloudflare zone:
TypeNameValue / Target
TXTmailv=spf1 a mx include:_spf.elasticemail.com ~all
TXTapi._domainkey.mailElastic Email DKIM public key
CNAMEtracking.mailapi.elasticemail.com
CNAMEbounces.mailbounces.elasticemail.net
TXT_dmarc.mailv=DMARC1; p=none;
Cloudflare note:
  • tracking.mail and bounces.mail must stay DNS only, not proxied.

​
Historical Providers

SES and SendGrid remain valid provider implementations behind the shared abstraction, but they are not the active production sender today. The historical setup notes are retained in:
  • docs/amazon-ses-email-infrastructure-tracker.md
  • docs/sendgrid-email-infrastructure-tracker.md
Those trackers describe previous experiments and should not be read as current production DNS state.
