Drip campaigns send a timed series to people who already opted in: day 0 welcome, day 3 check-in, day 7 offer reminder. WhatsApp makes this feel personal if the sender uses a real UK carrier +44, not a burned virtual rental.
Sequence design
- Day 0: confirm opt-in, set expectations
- Day 2 to 3: value message, no hard sell
- Day 5 to 7: soft CTA with reply prompt
- Stop sequence on any reply (human takeover)
Automation without API
Tools like scheduled reminders, CRM tasks, or lightweight scripts can queue drafts. A human or semi-auto tap sends from WhatsApp Business on the UK line. Keep total outbound under about 200 per day after the standard 2-week warm-up: full schedule.
Number setup
Buy a prepaid line at BuyUKeSIM ($25, crypto, no KYC, instant QR). Install on a dedicated phone. Register WhatsApp: setup guide. Compare to VOIP failures: virtual bans.
Metrics to watch

Disclaimer
Drip does not mean spam. Every contact must have consented to WhatsApp messages. Follow WhatsApp ToS and include easy opt-out in message one.
FAQ
Can drips run 24/7 unattended?
Risky. Meta prefers human-paced sending. Stagger by timezone.
