BetaMails — AI Email Platform | Full Source CodeBetaMails is a production-ready email SaaS that lets businesses send beautifully designed bulk emails directly from their own Gmail or Outlook inbox — no shared servers, no deliverability problems, no blacklists.What it doesUsers connect their Gmail or Outlook account using OAuth. Every email sent goes out from their own real inbox — not a shared sending domain using Gmail app password, which means emails land in the primary inbox, not spam.The built-in AI email designer lets users describe what they want in plain English and get back a fully formatted HTML email instantly, powered by OpenAI. They can then edit every element — layout, colours, fonts, tables- using the editor and preview exactly how it will look before sending.For bulk sending, users import a CSV of contacts and send to the entire list in one click. Under the hood, the email job is saved to DynamoDB, which triggers an AWS Lambda function. For bulk campaigns, Lambda pushes individual jobs into an SQS queue, which processes and sends emails one by one — respecting Gmail and Outlook rate limits automatically so no account ever gets flagged or banned.Single emails are sent immediately via SES and Nodemailer. Scheduled emails are stored and triggered at the set time. A full subscription system is built into Razorpay — Free, Pro, premium and Business plans are configured, with usage limits enforced automatically through the backend. No third-party billing setup needed.Full feature listGoogle login via AWS Cognito — secure, scalable authentication out of the boxGmail and Outlook OAuth integration — users connect their real inbox in under 60 secondsFull inbox viewer — read, reply, forward, and manage emails inside the appSent folder and spam folder — complete inbox management in one placeAI email generation — describe the email, get back production-ready HTML via OpenAI GPT Email design editor — edit text, layout, colours, fonts, tables, buttons, imagesEmail preview — see exactly how the email renders before sendingContact list import — upload a CSV, and contacts are ready instantlySingle send — send from Gmail or Outlook via SMTP and NodemailerBulk send — import a list and send to thousands, one by one via SQS queueEmail scheduling — set a time, and the email sends automaticallyAWS Lambda workers — DynamoDB stream triggers Lambda for every send jobSQS queue system — bulk emails processed individually, rate limits respectedCampaign history — full log of every campaign sentAI reply — users can reply to emails with AI-generated responsesRazorpay billing — Free, Pro, and paid plans with automatic usage enforcementPlans and pricing page — fully built and connected to the backendTech stackFrontend: Next.js 14, TypeScript, React 19, Tailwind CSS, shadcn/uiAuth: AWS Cognito with Google social loginDatabase: AWS AppSync GraphQL API backed by DynamoDBStorage: AWS S3Infrastructure: AWS Amplify — one command recreates the entire backendEmail workers: AWS Lambda, AWS SQS queue, AWS SES, NodemailerAI: OpenAI GPT API — email generation and AI replyPayments: Razorpay — subscription plans and payment ordersSecurity: AES-256-GCM encryption for all stored OAuth tokens, AWS Secrets Manager for API keysWhat the buyer getsFull Next.js source code, complete AWS Amplify backend configuration, Lambda function code for single send and bulk send workers, GraphQL schema for immediate AppSync deployment, SQS queue setup guide, environment variable template, and step-by-step setup documentation.
