[FEATURE] Implement Backend Functionality for Email Sending

[shreya5653]

Is this feature already requested?

• I have checked "open" and "closed" issues, and this is not a duplicate.

Problem or Missing Functionality

The current system cannot send emails to subscribers, which blocks newsletters and notifications from reaching users. It also lacks unsubscribe options and proper email authentication. This feature will add email sending capabilities with reliable delivery and unsubscribe support.

Feature Description

This feature will enable the backend to send emails using an SMTP server (like Gmail or SendGrid) for newsletters and notifications. It will include authentication (SPF, DKIM, DMARC) to avoid spam issues and add unsubscribe options for users.

Screenshots

No response

Would you like to work on this feature?

Yes

Implementation Plan

The feature will be implemented by integrating an SMTP service to enable email sending. We will develop a service for composing and sending emails, add an unsubscribe option for users, and set up a retry mechanism for failed attempts. After testing the functionality, the feature will be deployed to the production environment, with ongoing monitoring for delivery reliability.

@ajaynegi45 @Guhapriya01 I was studying the email-sending functionality, but I got delayed in raising the issue due to my exams. Now, I’d like to work on this issue. Please assign it to me.

@ajaynegi45 @Guhapriya01 I've been trying to run my project since yesterday, but I'm facing issues even after confirming that all dependency configurations are correct. After syncing the fork, I'm encountering errors in various files, such as missing beans in borrowing. Please advise if others are experiencing similar issues and what steps I can take to resolve this. I want to test my changes effectively.

[ajaynegi45]

I think you haven't add required field in resources folder.

[shreya5653]

I think you haven't add required field in resources folder.

@ajaynegi45
I added all the required fields in the resources folder. After resolving all the errors and adding Oauth configurations after logging in with my email its redirecting to same login page. Can you please tell me why this is so? I checked my redirecting url as well.

[shreya5653]

@ajaynegi45 While testing the recent changes, I temporarily disabled authentication for the relevant endpoints to ensure everything else was functioning correctly. This allowed me to validate that the logic was correct and that all expected flows were working as intended. I’ve attached the relevant screenshots in my PR for your reference.

@ajaynegi45 Thank you so much for your help so far. I will ask my issue to @rishabhrawat05. I temporarily bypassed the issue to test my changes, and everything is working correctly. It would be great if you could review my PR #89 so I can wrap this up and move on to a new issue.

Hey! Can you please share some screenshots of the error you are receiving while starting the application and also share screenshot of your application.properties file and application.production file.
I will try to fix the issue as fast as possible

Hi @shreya5653,

I saw your message about the redirect issue after logging in. Just to clarify, are you experiencing the redirect problem with the OAuth login or the basic login? Knowing this will help us assist you better. Also, if you could share any relevant screenshots that @rishabhrawat05 requested, that would be really helpful.

Okay Thank you so much @rishabhrawat05 . But I request @Guhapriya01 @ajaynegi45 to review my PR or at least let me know is my PR #89 under review coz this won't cause any conflicts with existing code.

[Guhapriya01]

@shreya5653, sure! We’ll review it and let you know soon if any changes are needed.

Regarding the error, since you’re receiving a 401 Unauthorized for all endpoints, it’s likely that the Bearer token isn’t being included correctly in the Authorization header, or it might be invalid. Please double-check to ensure that the token is included properly.

[rishabhrawat05]

Hey! @shreya5653
The redirect problem can only be fixed while creating the front end, as we cannot redirect to a different API just by logging in. We need a token to access different endpoints. Also,
I have reviewed your code thoroughly, and it needs some changes.
Here are the changes

1. Don't create extra EmailService and mail config files. The email sender/email service is already present. Here's how you can use it
   

2. While sending the email you have to pass notification as a parameter of email service, passing null will raise a proxy error. Here's how you can implement
   

3. Keep application.properties file as it is only change ${ENV:dev} to ${ENV:production} and use jwt.secretKey=eyJhbGciOiJIUzI1NiJ9.eyJSb2xlIjoiQWRtaW4iLCJJc3N1ZXIiOiJJc3N1ZXIiLCJVc2VybmFtZSI6IkphdmFJblVzZSIsImV4cCI6MTczMDEwNTk4MSwiaWF0IjoxNzMwMTA1OTg
   After that, your application.properties file should look like this
   

4. In the notification package -> NotificationType add two new values SUBSCRIBED and UNSUBSCRIBED. Here's how it will look
   

5. Also, Increase the length of NotificationType in Notifications class by applying length=20 or it will raise error

Hope these changes will help project improvement,
If you have any other issues please reach out I will help as fast as possible.

Thank you so much for your guidance! I really appreciate your help. While making the changes, I kept your suggestions in mind and did my best to implement them. I believe I’ve made some progress and achieved what we wanted, but I wasn’t able to follow your suggestions exactly as you mentioned, as some of them were a bit difficult for me to grasp.
