URGENT: HTTPS connection issue with email

Hello! It's unclear what you're trying to achieve. Perhaps you could provide more details about your current process and your specific question.

To be honest, I'm not too familiar with this. I've only recently become a co-manager of this workflow. I asked ChatGPT to help me create this:

Help me create a callin.io agent. I want it to have access to a document where I will update a list of entrepreneurs' email addresses every 24 hours to contact for selling our services, and I want it to respond to them in real-time without my intervention. The bot should have access to documents containing service prices and a sample email drafted by us, and these documents will be on our Google Docs. I want the bot to send me at the end of the exchanges, when it senses the client is ready to buy, a document with all important information like first name, last name, project, contact, whether they've dealt with other providers before, their budget, their preferences (e.g., color or order), etc. I want to know everything about them, absolutely everything from A to Z. And after the bot sends me this document, I want it to schedule a call with the client based on my availability via Calendly. The robot should be able to propose suitable services to the right person.

Unfortunately, there's a point in my workflow, which is "send a message" (the response to the client), that isn't working. It's not accepting the email address I'm using to run the workflow. I tried to force the email to work using a "set" node, but it's still not working.

Is it possible to help me because I need to validate to my manager that the workflow functions so I can sell it.

This is an international forum. English only please.
Also I am asking you in English and then you write a whole thing in French, a bit weird, isn't it?

To be honest, I'm not very familiar with it. I've been jointly managing this workflow for some time. I asked ChatGPT to assist me in building this:

Help me create a callin.io AI agent. I need it to access a document where I will update a list of email addresses of entrepreneurs to contact every 24 hours to market our services, and I want it to reply to them in real-time without my involvement. The bot will require access to documents containing service pricing and a sample email template authored by us. These documents will be hosted on our Google Docs. At the conclusion of the interaction, when it detects the client is ready to purchase, I want the bot to send me a document with all the crucial details, such as first and last name, project, contact information, prior engagement with other service providers, their budget, and their preferences (color, order, storage, etc.). I want to know everything about them, from start to finish. Following the bot sending me this document, I want it to schedule a call with the client based on my availability via Calendly. The bot must be capable of suggesting services customized to the individual.

Unfortunately, there's a specific point in my workflow, the "send a message" function which handles client responses, that isn't functioning. It's not accepting the email address I use to execute the workflow. I attempted to force the email to work using a "set" node, but it remains unsuccessful.

Could you offer any assistance, as I need to confirm to my manager that the workflow is operational before I can proceed with selling it?
