Apollo charges $49/month before you touch a single contact. ZoomInfo starts at $14,995/year. Sendjump has no monthly fee. Buy credits when you need them, upload your list, and pay only for contacts we actually return. $0 for every miss. $5 to start.
No sales call. No setup fee. No monthly commitment. Use the web console to upload a CSV directly, or call the API from your pipeline. Either way, credits are only spent on contacts we actually return.
Upload via the web console or POST a CSV/JSONL to the API. One required column: linkedin_url. Every other column passes through unchanged.
The job runs in the background. Poll status if you want, or just wait for the signed webhook to fire when processing is done.
Download Apollo-compatible CSV or raw JSONL. Credits are only spent on rows where we actually return contact data.
Three things that separate Sendjump from every other enrichment tool on the market.
Apollo, ZoomInfo, Clearbit - they all charge you every month whether you run a list or not. Sendjump has no monthly fee. Buy a credit pack when you need one and use it on your schedule. Credits never expire.
Every other enrichment tool charges you whether they find a contact or not. We don't. Credits are reserved on upload and released back to your balance for every contact we fail to return.
Start in the browser with no code, or drop the API into your existing automation stack. Same pricing model, same outputs, same contact-level economics.
Run Sendjump from the web console, through a CSV workflow, or directly from Claude, Cursor, n8n, and any OpenAPI-aware stack.
One required column: linkedin_url. Every other column passes through the round-trip intact.
Fire and forget. The signed webhook fires when the job completes. Poll status anytime - but you don't have to.
Download in Apollo-compatible CSV or raw JSONL. Your existing downstream tooling keeps working.
Drop the base URL into Claude, Cursor, or any tool-use loop. No prompt engineering. No wrapper needed.
X-RateLimit-Limit and X-RateLimit-Remaining on every response. Your agent always knows where it stands.
Unknown columns pass through unchanged. Your data model survives the round-trip from upload to download.
Buy credits. Use them when you need them. Credits never expire. You only pay for contacts we return.
Credits reserved on upload. Released for every miss. You are never charged for a contact we couldn't return.
I built this for Markster's own outbound before anyone else used it. We ran 50,000 contacts through it. The pay-only-for-hits model paid for itself in the first campaign - we would have burned a significant budget on misses with any other provider. It paid for itself on campaign one.
Buy a credit pack, upload your list, and pay only for contacts we actually return. No subscription. No contract. No monthly charge waiting for you at the end of the month. $5 to start.
