Don’t send to a list you can’t trust.
Give Doe the list, whether it was exported, bought, or stitched together from three sources, and it verifies every email, kills the duplicates, fills the gaps, and flags the rows you shouldn’t touch. You send to a clean, deliverable list instead of finding out one bounce at a time.
Hand Doe a list you already have, whether it’s a CSV, an exported segment, or a list someone bought, and it verifies every email, removes duplicates, fills in missing fields, and flags do-not-contact and role-based addresses before you send. It re-finds a fresh verified email when an old one is dead rather than deleting the row, so you keep the contact. The result is a clean, deliverable list with the verification status on every row, so a bad list doesn’t quietly torch your sending domain.
What changes
| Dimension | Before | With Doe |
|---|---|---|
| How you verify | Paste into a checker tab by tab, or skip it | Whole list verified in one pass |
| Dead emails | Deleted, contact lost | Re-found fresh and verified; contact kept |
| Duplicates & gaps | Eyeballed; missed; rows half-empty | Merged and enriched automatically |
| Do-not-contact | Noticed after you’ve already emailed them | Flagged with a reason before you send |
From a risky list to a deliverable one
Google SheetsDoe ingested the sheet or upload, mapped the columns even when they were inconsistent, and normalized names, companies, and domains so the rest of the work runs on clean inputs
Doe checked deliverability on each address with its native verification and, where an email came back dead, ran a waterfall to find a fresh verified one for that person, so you keep the contact instead of losing the row
Doe merged duplicate people and companies, kept the best record, and used its native enrichment to fill missing titles, company sizes, and domains so the list comes back complete as well as clean
The Judge marked role-based addresses (info@, sales@), known unsubscribes and suppressed contacts, and risky or catch-all emails, separating them out with a reason rather than silently deleting them, so you decide
HubSpotDoe wrote back a verified, de-duplicated, enriched list with a status on every row, and posted a summary of how many verified, how many fixed, and how many flagged, so you know the list is safe before it goes anywhere
One bad list can torch a sending domain you spent years warming.
You’ve got a list. Maybe marketing exported it, maybe a vendor sold it, maybe it’s three spreadsheets taped together. It looks fine. Then you load it into your sequencer and the bounces start at 8%, then 12%, and now your domain reputation is dropping, your good emails are landing in spam, and the campaign you spent a week building is poisoning the channel for the next one. The mailbox providers don’t care that it was an honest mistake; a few percent of complaints or hard bounces and you’re throttled.
So the responsible move is to verify the list first. Except that means pasting addresses into a checker tab by tab, eyeballing duplicates, guessing which "info@" rows are role-based, and noticing too late that two of these people unsubscribed last quarter. It’s tedious enough that it gets skipped, which is exactly how the bad list goes out.
Get started with the right source material
Add your library and tools
Add or select the source files Doe should use, then connect the tools this task needs. No API keys, no engineering.
Describe what you need
“Here’s a list. Verify every email, re-find a fresh one where it’s dead, remove duplicates, fill in missing titles and company size, and flag role-based addresses, unsubscribes, and risky emails. Write the clean version back and tell me the before/after counts.”
It runs on schedule
Run it on demand, or set it to re-verify a standing list before every send. You always mail a list that was verified today.
List Verification & Cleanup FAQ
A verification tool tells you which addresses are dead and stops there, leaving you with a shorter list and the same holes. Doe verifies and then fixes: it re-finds a fresh, deliverable email for the people whose address bounced, merges duplicates, fills missing fields, and flags do-not-contact rows with a reason. You get a usable list instead of one that’s just been pruned.
