BlitzRocket + Klaviyo
Send verified giveaway entrants straight into Klaviyo flows
Giveaways are the fastest way to grow a Klaviyo list — if the emails are real. BlitzRocket syncs verified entrants directly into the Klaviyo list you choose, in real time, after AI fraud detection has filtered out bots, duplicates, and disposable addresses. New subscribers land in your flows ready for a welcome sequence built for giveaway-sourced leads.
Why connect Klaviyo?
Real-time list sync
Verified entrants are added to your chosen Klaviyo list as they enter — no CSV exports, no end-of-campaign batch uploads.
Deliverability protection
AI fraud detection blocks bots, duplicate accounts, and disposable emails before they ever reach Klaviyo, keeping your sender reputation clean.
Flow-ready subscribers
Because entrants arrive in a dedicated list, you can trigger a giveaway-specific welcome flow the moment they're synced.
Per-campaign list targeting
Each campaign can sync to a different Klaviyo list, so a product-launch giveaway and an ambassador program never mix audiences.

Klaviyo integration FAQ
How do entrants get into Klaviyo?
BlitzRocket pushes each verified entrant to your selected Klaviyo list through Klaviyo's API in real time. You connect once with a private API key and choose the destination list per campaign.
Will a giveaway hurt my Klaviyo deliverability?
Not with verification in place. BlitzRocket's AI fraud detection blocks bots, duplicates, and disposable addresses before sync, and only verified entrants are pushed — so the list you build is one you can actually send to.
Can I trigger a Klaviyo flow when someone enters?
Yes. Point your campaign at a dedicated Klaviyo list and attach a 'Added to list' triggered flow to it. Most brands use a giveaway-specific welcome sequence that converts entrants into customers.
Can different campaigns sync to different lists?
Yes. The Klaviyo connection is configured per contest, so each campaign can target its own list or segment strategy.

Thirteen providers natively: Klaviyo, Mailchimp, Kit (formerly ConvertKit), ActiveCampaign, MailerLite, Campaign Monitor, Drip, EmailOctopus, GetResponse, Sendy, Sendlane, Gist, and Autopilot — plus any platform that accepts webhooks.
