Why did Ocean.io return fewer emails than contacts?
The Ocean.io help pages give 4 common reasons. The first to rule out: Not every contact comes back with an email, and Ocean.io's own example expects emails for most contacts, not all of them.
What causes it?
Not every contact comes back with an email, and Ocean.io's own example expects emails for most contacts, not all of them.
In the Ocean.io help:
With 50 contacts and a ~79% find rate, expect around 40 verified emails for roughly 40 credits.
Workflows | API Docs | Ocean.io, read 2026-11-12.If a people search through the API is set to one person per company, it returns at most one contact for each company, so fewer contacts and emails come back.
In the Ocean.io help:
peoplePerCompany: 1 ensures you get at most one contact per company, choosing the highest-matched person.
Workflows | API Docs | Ocean.io, read 2026-11-12.Some emails come back marked guessed, meaning high-confidence but not confirmed with the mail server, so a count of confirmed emails leaves those out.
In the Ocean.io help:
guessed emails are high-confidence but not SMTP-confirmed.
Workflows | API Docs | Ocean.io, read 2026-11-12.When an account runs out of credits, Ocean.io does not process the request and charges nothing, so reveals can stop partway until credits are added.
In the Ocean.io help:
The request is not processed and no credits are deducted.

How do I check it myself?
If you use the Ocean.io API, check the credit balance for credits left and how much of the daily limit remains.
In the Ocean.io help:
Call Get Credit Balance at any time to see your remaining credits and daily rate limit status.
Credits | API Docs | Ocean.io, read 2026-11-12.Before a large batch of reveals through the API, check how much of the daily limit is left, so the batch is not cut short.
In the Ocean.io help:
Check dailyLimitRateLeft from Get Credit Balance before starting large batch jobs.

How does Ocean.io work with Feder?
- Connect Ocean.io to Feder and it joins your Interest apps.
- When you connect Ocean.io, Feder checks the connection straight away and shows Connected only when that check passes. If a reading cannot be taken later, Feder shows it as not read, never as zero.
Some numbers are too quiet to judge daily, such as a form filled in a few times a week. Until there is enough of your own history to judge a change, Feder says it is still learning and scores nothing, rather than guessing.
See whether you can trust the numbers in Ocean.io, one of your Interest apps. Feder only reads. It never changes anything in Ocean.io.
