Telegram + SendPulse Automation for Email Collection and API Sync

A Python automation system for collecting emails from Telegram and syncing contacts with SendPulse campaigns via API.

Problem

The client needed to automate email collection from Telegram and eliminate manual transfer of contact data into the email marketing system.
The main goals were:

• set up automatic email collection from Telegram
• send contacts directly into SendPulse campaigns via API
• ensure stable operation without constant manual supervision
• add email filtering to improve data quality
• prepare the system for restart, token refresh, and future maintenance

Process

The project was built around Telegram API, SendPulse API, and reliable server-side automation logic.

• developed a Python script using Telethon for Telegram interaction
• configured SendPulse API integration for contact synchronization
• set up handling for api_id, api_hash, tokens, and sessions
• deployed the system on a RunPod server for continuous operation
• added filters for selecting relevant email addresses, including Gmail-only scenarios
• prepared documentation for setup, restart, log monitoring, and token refresh

Solution

The final result was an automation system that collects emails from Telegram and sends them to SendPulse without manual routine work.

Key solutions delivered:

• Python automation script
• Telegram integration through Telethon
• SendPulse API synchronization
• server deployment on RunPod
• email filtering based on defined conditions
• token and session handling
• support-ready documentation for ongoing use
• readiness for future API-related adjustments

Result

The result was a practical automation infrastructure for lead collection and syncing email contacts with the marketing system.The solution reduced manual work, streamlined data processing, and created a reliable technical foundation for future scaling, maintenance, and adaptation to external API changes.
