No email doesn’t mean no follow-up
Many cards are minimal (phone + website). You can still follow up—pick the most realistic channel and keep context.
Options that work
- LinkedIn: search by name + company.
- Company website: contact page or generic email.
- Main phone line: ask for the direct email.
- SMS/call: if you have a mobile number, keep it short and respectful.
What to avoid
- Guessing the email without verification.
- Over-scraping and wasting time.
- Generic messages with no meeting context.
