BlitzRocket + Kit (formerly ConvertKit)
Built for creators: sync giveaway entrants to Kit automatically
Kit (formerly ConvertKit) is the email home for creators — and giveaways are the fastest way to fill it. BlitzRocket syncs every verified entrant into your Kit list as they enter, after AI fraud detection has screened out bots and disposable emails. Grow a list the algorithm can't take away from you.
Why connect Kit (formerly ConvertKit)?
Creator-first list growth
Turn YouTube subscribers, podcast listeners, and social followers into Kit subscribers you actually own — with a giveaway as the bridge.
Real-time sync
Verified entrants flow into your Kit list while the campaign is live, so your welcome sequence starts working immediately.
Fraud-screened subscribers
AI fraud detection blocks bots, duplicates, and throwaway emails before they reach Kit, protecting your open rates and your plan cost.
Campaign-level targeting
Sync different campaigns to different lists — a course-launch giveaway and a community contest never pollute each other's audience.

Kit (formerly ConvertKit) integration FAQ
Is this the same as the ConvertKit integration?
Yes. ConvertKit rebranded to Kit, and BlitzRocket's integration uses Kit's current API. If you've seen it called ConvertKit elsewhere, it's the same platform.
When do entrants get added to my Kit list?
In real time, as soon as each entrant verifies their email and passes fraud screening. There's no batch export step.
Can I trigger a Kit sequence for giveaway entrants?
Yes. Point the campaign at a dedicated list and attach your welcome sequence to it in Kit. A giveaway-specific sequence that introduces you and your work typically converts entrants into long-term readers.
Will giveaway entrants hurt my open rates?
Verified-only sync plus AI fraud filtering means the subscribers you receive are real people who wanted to enter. Pair that with a strong welcome sequence and giveaway-sourced segments can perform close to organic signups.
What if I use a different email platform?
BlitzRocket natively supports 13 providers including Klaviyo, Mailchimp, ActiveCampaign, and MailerLite — plus webhooks and a REST API for anything else.
Pairs well with
Mailchimp
Push verified contest entrants into any Mailchimp audience automatically. Fraud-filtered emails, real-time sync, and automation-ready subscribers.
Klaviyo
Sync every verified contest entrant to a Klaviyo list in real time. Trigger welcome flows, segment giveaway leads, and protect deliverability with AI fraud filtering.
Zapier & Webhooks
Pipe verified signups, purchases, and reward redemptions into Zapier, Make, or any tool that speaks webhooks. Plus a full REST API for custom builds.
