hunter.io 202 accepted verification never completes

Not specified by the original author.

TL;DR

A 202 means the verification was accepted and is still processing, which is normal for seconds, not hours. Poll the result endpoint with the returned ID on a backoff schedule, and set a timeout after which you mark the address unknown. If verifications never complete, the usual causes are a stuck queue on Hunter's side or an identifier the verifier cannot process. Do not poll forever.

hunter.io 202 accepted verification never completes

Use this when

• The verify endpoint returns 202 and the result stays pending.
• Some verifications complete and others hang.
• You are polling and want to know the sane limits.

Not for this skill when

• The response is 422. The email format is invalid; nothing will ever complete.
• The error is 401. That is the API key.

Steps

1. Poll the result endpoint with the verification ID, starting at 10s intervals and backing off to minutes. Verify: most results land within a few polls.
2. Set a hard timeout: after 30 minutes pending, mark the address verification-unknown and move on. Verify: your pipeline never blocks on one address.
3. Check whether the hanging addresses share a pattern (role accounts, catch-all domains, unusual TLDs). Verify: the pattern explains which ones hang.
4. For bulk work, prefer the bulk verification job over single calls; it has its own completion semantics. Verify: the job status endpoint shows real progress.
5. If nothing completes for hours across all addresses, check Hunter's status page and your quota. Verify: the problem is platform-side, not your code.

hunter verification stuck pending

The short search, same polling-timeout fix.

hunter.io 202 no result

Status phrasing, points at step 1.

email verification never finishes hunter

Symptom phrasing, lands on the pattern check.

Compatibility: Hunter.io email verification API. Single verification is async by design; 202 is not an error.

Why it happens

Verification involves live mailbox checks that take real time, so the API accepts the job (202) and finishes later. Some addresses cannot be verified at all (greylisting servers, catch-alls that never answer), and those jobs sit pending until they time out server-side. Your code has to impose its own deadline because the API will not do it for you.

Edge cases / pitfalls

• Polling every second for an hour burns quota and goodwill. Back off.
• A verification that completes as "risky" is a completed result. Do not treat non-deliverable as pending.
• Catch-all domains verify slowly by nature. Budget extra time or skip them.
• Never treat a perpetually pending verification as valid. Unknown is unknown.

TL;DR

Fix this in Hunter by acting on the exact message first: verify the attendee list in small asynchronous batches, collect results per batch as they finish, and prioritise speakers and target accounts so the most valuable addresses complete first. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one record, then rerun the full scope and reconcile the counts.

Agent timed out verifying emails for a conference attendee list, the Hunter queue backed up

Use this when

• The operation in Hunter fails with this exact message: Agent timed out verifying emails for a conference attendee list, the Hunter queue backed up.
• The same failure repeats on retry with unchanged inputs.
• A run, import, export or alert is blocked until this item completes.

Not for this skill when

• The message is a permission or platform outage notice. Resolve that first, then return here if this error remains.
• The operation completes and you only disagree with its output. That is a quality review, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in Hunter, and copy the full message plus the record, account or list involved into the run notes. Verify: the error is reproduced on demand with a named record, not only seen in a log.
2. Apply the specific fix for this error: verify the attendee list in small asynchronous batches, collect results per batch as they finish, and prioritise speakers and target accounts so the most valuable addresses complete first. Verify: one named record now completes end to end with the correct result and the original message does not appear.
3. Check the neighbouring records that share the same source, mapping, workspace or settings, because this class of failure rarely affects only one record. Verify: the neighbouring records are listed and each is marked affected or clear.
4. Compare the result counts, fields or alerts against the source in Hunter so a silent partial success is caught before sign off. Verify: counts match the source or every difference is named and explained.
5. Rerun the original operation in Hunter on the previously failing scope, watching for the same message rather than assuming success from a quiet log. Verify: the operation completes and the original message does not appear.
6. Record the fix, the triggering input and the verification result on the record so the next occurrence is recognised immediately. Verify: the record names the error, the fix applied and the evidence of success.

Why it happens

Submitting the whole list as one synchronous job queued it behind other work, and the run waited idle instead of collecting finished batches.

How to fix this failure in Hunter

The how to phrasing for the same failure. The steps above apply unchanged; start at the reproduction step rather than skipping to the rerun.

Troubleshooting this failure in Hunter

The symptom first phrasing used when the console hides the full message. Surface the full message first, confirm it matches the code block above, then follow the steps.

Compatibility: Hunter at current versions, plus the platform API or console the query names; no extra tooling beyond the source system access needed to verify counts.

Why it happens

Domain discovery matched a defensive parked registration with the same name, and a parked domain has no mail infrastructure or staff addresses to find.
