Tips to Make Your Bot Feel Human
• Name it—“Sunny” sounds warmer than “Support Bot.”
• Add fallback replies like “Hmm, let me loop in a human.”
• Use emojis sparingly—one smiley per response max.
• Set office hours so the bot knows when to hand off to email.
Integrations That Make You Look Pro
• Calendly—bot books meetings while you binge Netflix.
• Zapier—send leads straight to Google Sheets or Slack.
• Stripe—answer pricing questions and drop a payment link.
