Sendbase uses your AWS account to store and manage all email resources.

​
Architecture

  • Sending Email: All email sending operations are executed directly through AWS SES using your credentials. Sending quotas and limits are based on your AWS account’s SES configuration.
  • Contact List: Contacts are stored and retrieved directly through AWS SES, not in our database. Your contact data never leaves your AWS account.
  • Email Templates: Email templates are stored in AWS SES.
  • Email Identity: Verified domains are configured and stored in AWS SES, determining which addresses you can send from.
  • S3: Assets like images and contacts to import are stored in your S3 bucket.
  • SNS: SES configuration sets publish email events (sends, deliveries, bounces, complaints, opens, clicks) to SNS topics, which then send webhooks to the application for message logs.
  • Metrics: Email analytics (delivery rates, bounces, complaints, opens, clicks) are collected from AWS CloudWatch in your account.

​
Benefits of This Architecture

  • Data Ownership: All your data stays in your AWS account with no platform lock-in.
  • Dedicated Email Reputation: Your sending reputation is isolated to your AWS account.
  • Scalability: Leverage AWS’s infrastructure and your SES sending limits.
  • Security: Your data remain under your control.
