My BFCM checklist for Klaviyo — start six weeks out
Black Friday is won in October. A week-by-week checklist for warm-up, list growth, campaign planning and flow updates.
The brands that win Black Friday Cyber Monday aren't the ones with the biggest discount — they're the ones who prepared.
Six weeks out
- Review deliverability: authentication, complaint rates and engagement by provider.
- Start gradually increasing send volume to your engaged segments.
Four weeks out
- Launch an early-access sign-up form for SMS and email.
- Finalise your offer, creative and campaign calendar.
Two weeks out
- Build and QA every campaign. Test on mobile, desktop and in dark mode.
- Update flows: pause discounts in welcome flows that would undercut the sale.
Sale week
- Send early access to VIPs first, then widen to engaged segments.
- Monitor results daily and resend to non-openers with a new subject line.
