Turn form signups into qualified sales alerts. The setup checks if an email is real, scores the contact for customer fit, and pushes hot leads to Telegram in near real time. It helps sales teams focus on people who are more likely to buy.

Here is how it works. A hosted form collects a business email. The email goes to Hunter for verification to filter out fake or risky addresses. If valid, the flow calls MadKudu to fetch a customer fit score for that person. When the score is above 60, a Telegram message sends the email and top signals to your chat. If the score is low or the email is invalid, the item is quietly dropped.

To use it, you need a Hunter API key, a MadKudu key, and a Telegram bot token with the correct chat ID. Set your own score threshold and message format to match your playbook. Teams can respond faster, reduce time wasted on junk leads, and move more qualified leads into the pipeline. Great for small sales teams, founders with inbound interest, and agencies screening new prospects.

• Hosted form captures a single business email with a clear title and description.
• Email verification with Hunter filters undeliverable or risky addresses before scoring.
• Conditional logic stops invalid emails from moving forward.
• HTTP request to MadKudu fetches a customer fit score based on the email.
• Score threshold check routes only high fit contacts to alerts.
• Telegram message includes the email and top fit signals for fast context.
• Silent branches discard invalid and low fit leads to reduce noise.

• Reduce manual lead checks from hours per week to minutes
• Cut invalid email submissions by up to 70 percent using real email verification
• Send high fit leads to Telegram instantly to speed up first response
• Focus sales time on the best prospects by using a clear score threshold
• Connect Hunter, MadKudu, and Telegram without custom code

1. Import the template into n8n: Create a new workflow in n8n > Click the three dots menu > Select 'Import from File' > Choose the downloaded JSON file.
2. You will need accounts with Hunter, MadKudu and Telegram. See the Tools Required section above for links to create accounts with these services.
3. In the n8n credentials manager, create a new Hunter credential. If unsure, double click the Hunter node, open the Credential to connect with dropdown, click Create new credential, then follow the on screen steps to add your Hunter API key from the Hunter dashboard API page.
4. Open the HTTP Request node for MadKudu. In Credential to connect with, click Create new credential and choose HTTP Header Auth. Add the header required by MadKudu per their API docs with your API key. Name the credential clearly, for example MadKudu Prod.
5. Create a Telegram bot token using BotFather in Telegram and copy the token. In n8n, open the Telegram node, click Create new credential, and paste the bot token. Send a message to your bot to generate a chat ID, then set that chat ID in the node.
6. Open the Form Trigger node and confirm the form title, description, and the field label for the email matches your needs. Keep the business email prompt clear.
7. Review the email validity check and keep it connected to Hunter so only verified emails continue to scoring.
8. Open the score check and set your own threshold. The default is greater than 60. Raise or lower it based on your ideal customer fit.
9. Click Test workflow in n8n. Submit a real business email in the form preview. Watch the execution and confirm the path taken on each node.
10. Check your Telegram chat for the alert. If no message arrives, confirm the chat ID, bot permissions, and that the score cleared your threshold.
11. If errors occur, verify API keys and quotas in Hunter and MadKudu, confirm the HTTP header values, and make sure your Telegram bot is not blocked by the chat.
