I generally use n8n for my email responses, for lead generation, for image generation, responses to all my WhatsApp messages, creating bookings, and handling all my tasks for meetings.
For lead generation, I gave all the contacts to n8n and made it write the email and automated the email sending workflow for lead generation, and the conversion rate was around 70%. If I message 100 users, I get 70 users converted and experienced a growth in business by around 50%.
Regarding the memory feature: whenever I get a booking through my WhatsApp, the memory feature stores everything inside it and later helps other clients to check my schedule and book a call with me for a specific time when I am actually free.
