QuickEmailVerification
Email MarketingQuickEmailVerification is an email verification and list cleaning API. Agents verify a single address in real time, upload a list for bulk verification, poll job status, download the cleaned results, and delete finished jobs.
What This Integration Enables
QuickEmailVerification is built for the list you already have. Its shape is the bulk job with a real report: you upload a file, you poll it, and you download a named slice of the result rather than one undifferentiated dump. The slices matter. You can pull only the addresses worth mailing, or one verdict category, or the full report, which preserves every column from the file you sent. That last detail is what turns a verification run from a report somebody reads into a step a flow can act on, because the results come back joinable to your own records.
FlowRunner agents drive the whole cycle: assemble the addresses from wherever they live, upload the file, poll until the job completes, download the slice the workflow needs into FlowRunner file storage, and clean up the job afterward. A single real time check is there for the moments that need one, and a sandbox mode exercises the whole path end to end without spending a credit, with the simulated outcome chosen by the local part of the address you send. One thing worth reading closely in any flow built on this connector: the field to act on when the question is whether to actually mail somebody is safe to send, not the headline result. An accept all domain answers valid while proving nothing.

Use Case Scenarios
-
Quarterly hygiene with the writeback built in
A scheduled agent pulls every mailable contact from Klaviyo and uploads them with Upload Email List. It polls Get Job Status until the job reports completed, then calls Download Report twice: once for the safe to send slice and once for the full report. The full report still carries the contact IDs that went up with the file, so the agent joins the verdicts straight back onto the records without fuzzy matching on address. Invalid addresses are suppressed, unknown addresses are left alone and tagged for a later look, and the counts post to Slack. Delete Email Job clears the finished job from the account.
-
A verification step inside a form flow
A gated content form writes a lead into ActiveCampaign. Before the nurture sequence is allowed to start, the agent calls Verify Email on the address and reads the safe to send field. Addresses flagged as disposable never enter the sequence. Role addresses do enter it, but on a different track, because a shared address at a target account is a signal rather than a problem. When the response carries a typo suggestion, the agent records it on the lead for the sales owner to see rather than acting on it.
-
Building the flow before spending anything
While the workflow is being assembled, every verification step points at Verify Email In Sandbox. The address local parts documented by the vendor let the agent walk deliberately through each outcome the real endpoint can produce, so the branches for safe to send, free provider, rejected and invalid domain are all exercised against the real response shape without a credit leaving the account. Once the branches behave, the flow is switched to the live action. The sandbox proves the plumbing. It never proves an address exists, and a flow that treats it as verification is testing itself.
Human-in-Loop Highlight
Credits for a bulk file are deducted the moment the file is accepted, for the entire file, not as the addresses are processed. A short balance answers with a payment error and nothing at all gets verified. The awkward part for an agent is that this connector exposes no operation that reports the remaining balance, so the agent can calculate exactly what a run will cost and has no way to see what it has to spend. That is the gate. Before an unusually large hygiene run, the agent stops and posts what it can prove: "Assembled 214,000 addresses for the Q4 hygiene pass, up from 96,000 last quarter because the event imports were included this time. Upload Email List debits the full file on acceptance. Confirm the balance covers it, or confirm a narrower segment?" A person opens the dashboard, sees the number the API will not hand back, and answers. Everything else in the run is the agent's job. The one call that spends the whole budget in a single request waits.
Agent Capabilities
6 actionsSingle Verification
2- Verify Email Verifies one address in real time and returns the verdict, the reason behind it, the disposable, accept all, role and free provider flags, the normalized address split into user and domain, the preferred MX record, and a typo suggestion when one applies. When the question is whether to actually mail the address, read safe to send rather than the headline result: an accept all domain answers valid while proving nothing.
- Verify Email In Sandbox Returns a mock verification result without spending a credit, so an integration can be exercised end to end against every outcome the real endpoint produces. The simulated verdict is chosen by the local part of the address you send, with documented prefixes for each result. It proves plumbing, never whether an address exists.
Bulk Jobs
4- Upload Email List Uploads a CSV of addresses for bulk verification and returns the job identifier. Supply either an address array, which is turned into a single column CSV, or the URL of a CSV to forward as is. Extra columns in your file are preserved in the report. Credits for the whole file are deducted the moment it is accepted rather than as it processes, and a short balance is refused with nothing verified.
- Get Job Status Reads a bulk verification job: its status, how long it took, the counts split into safe to send, valid, invalid and unknown, and the download links for each of those slices plus the full report. The vendor embeds your API key inside every download URL it returns, so those links are credentials, and this action masks them.
- Download Report Downloads one slice of a finished bulk job and stores it in FlowRunner file storage, returning the URL. Choose the safe to send list to get only the addresses worth mailing, one of the verdict slices, or the full report, which keeps every original column from the uploaded file alongside the results.
- Delete Email Job Deletes a bulk job and its reports from the account. A job still processing cannot be deleted, and a list uploaded by hand through the web interface cannot be deleted through the API at all, only one uploaded by Upload Email List. Anything left undeleted is removed by the vendor's own retention policy after ninety days.
