Telegram Emailer Bot

The project is to build a Telegram bot that lets me fire off a single, fully-customised email from the bot. Inside the conversation I’ll be able to:
• pick or manually type the sender address (either drawn from a small pre-defined list I supply or typed on the spot),
• enter a subject line,
• choose an HTML template stored in the bot or upload a fresh template file on demand,
• hit send and have the message land in the recipient’s inbox, not spam.

Deliverability is the single most important metric, so the code must handle the full SMTP flow with proper SPF, DKIM and DMARC signing. I’m open to whichever SMTP service or self-hosted option you recommend; please guide me on the best route for high inbox rates.

Acceptance criteria
1. Bot commands run smoothly inside Telegram for the above actions.
2. At least 95 % inbox placement in test sends to Gmail, Outlook and Yahoo accounts.
3. Clear, commented source code plus a short README so I can update sender lists or templates later.

If you’ve already shipped mailer solutions, that’s a huge plus. Let’s get this running quickly and I’m happy to adjust milestones once we see solid inbox performance. I can provide examples for reference
