Instant Lead Follow-Up: Automated Email & SMS Workflow

Turn leads into clients in under 60 seconds. This instant lead follow-up workflow automatically sends personalized emails and SMS messages the moment a prospect submits your inquiry form, while logging everything to your CRM and notifying your team — no manual intervention required.

What this workflow does

Built with n8n's native form trigger (no external dependencies), this automation workflow springs into action instantly when leads submit your contact form. It normalizes lead data including proper name formatting and E.164 phone number conversion, then simultaneously sends a personalized follow-up email via Gmail using the prospect's first name and requested service details.

The workflow sends an immediate SMS follow-up through Twilio integration, gracefully skipping invalid phone numbers to prevent errors. Every lead gets logged to your Google Sheets CRM with automatic email-based deduplication, while business owners receive instant notification emails with complete lead summaries.

• Service businesses: Follow up on consultation requests for legal, financial, or professional services where speed determines conversion
