Migrate email service from SendGrid to AWS SES

[Giolii]

Summary

Migrates the email service from SendGrid to AWS SES (Simple Email Service) for better integration with existing AWS infrastructure.

Changes

• Created new ses-service.ts to replace sendgrid-service.ts
• Removed old sendgrid-service.ts file
• Updated email-controller.ts
• Updated account-service.ts
• Added @aws-sdk/client-ses dependency
• Removed @sendgrid/mail dependency

Environment Variables Changes

Removed:

• SENDGRID_API_KEY

Added:

• AWS_ACCESS_KEY_ID
• AWS_SECRET_ACCESS_KEY
• AWS_REGION

Important Configuration Notes

AWS Region: The AWS_REGION must match where your SES email domain is verified. Using the wrong region will cause email sending to fail.

EMAIL_USER (Sender): Must use a domain registered or verified email address in AWS SES. The local part can be customized:

• Valid, verified domain: [email protected]
• Valid, verified domain: [email protected]
• Valid, verified domain: [email protected]
• Valid, verified email address: [email protected]
• Invalid: [email protected] - Will fail silently

If an unregistered email is used, the database will register the account but verification emails will not be sent.

CONTACT_US_LA (Receiver): Can be any valid email address.

Affected Features

• User registration emails
• Password reset emails
• Contact form emails

Testing

• Email sending functionality verified
• Registration confirmation emails work
• Password reset emails work
• Contact form emails work
