Every thread you’ve been CC’d on holds a name worth keeping. MailMop finds them, de-duplicates them, and hands you a clean contact list — without ever reading a word of your email.
No spam, no sharing your address. One email when your place is ready, and nothing else.
No data entry, no copying addresses out of threads one at a time.
A Chrome extension, not another dashboard to log into. It lives beside Gmail where you already work.
One consent screen, two permissions. MailMop works through your mail in the background — first contacts inside two minutes.
De-duplicated by address, role accounts flagged, each contact showing the subjects they appeared on. Search, filter, sort.
Clean UTF-8 CSV that opens properly in Excel, by an explicit action — nothing syncs behind your back. Direct CRM sync is planned for after the beta, not in it.
We would rather tell you plainly than have you find the gaps yourself.
Every CC’d address across your threads, with the sender name and the subject it appeared on.
One record per address, however many times and spellings it appears.
See which conversations each contact came from — the context that makes a list usable.
finance@, legal@, info@ flagged automatically so you can exclude them.
Airline no-replies, booking relays and tracking senders spotted from the address itself — the junk that clogs an auto-built contact list.
Clean UTF-8, configurable columns, opens properly in Excel.
One control clears all stored data from your browser.
Field mapping and duplicate checking, pushed on your explicit action. In build after the beta opens.
Second and later scans fetch only what’s new.
Not a feature we’ve deferred — one we are technically unable to build. See below.
MailMop cannot read your emails. Not “doesn’t” — cannot. The permission we request returns headers only, so message bodies and attachments are unreachable by design.
We request Google’s gmail.metadata permission. It returns sender, recipients, CC, subject and date. The Gmail API refuses to return message bodies or attachments to us at all.
Extracted contacts are stored in your own browser, not on our servers. Nothing leaves your machine unless you press export.
We don’t sell contact data, share it between users, or use it for advertising. One click wipes everything MailMop has stored.
The permission MailMop needs is one Google classes as restricted, and apps using it go through a review process before they can be offered publicly. Until that completes we can only admit a limited number of people, each added by hand. It also suits us: we would rather run a small, honest beta than a big launch, because we want to know whether the extracted lists are genuinely useful before asking anyone to pay for them.
There will be a free tier that is genuinely usable, and paid tiers for larger inboxes and CRM integrations. Beta users won’t be charged during the beta, and we’ll tell you the pricing before it ever applies to you.
Gmail and Google Workspace, in Chrome. Outlook isn’t supported and isn’t in the current plan — we would rather do one thing properly first.
CC, definitely. BCC is genuinely uncertain — Google’s documentation doesn’t confirm whether a BCC header survives on stored sent messages, so we’re testing it before we claim it. We’d rather under-promise here.
The first couple of hundred contacts appear within two minutes. A full pass over a 5,000-message mailbox takes around twenty minutes, because Google rate-limits how quickly any app may read from your account. It runs in the background and survives closing the window, so in practice you start it and forget it.
MailMop gives you the list; what you do with it is your responsibility, and UK GDPR and PECR apply to you as they would to any other list. MailMop doesn’t send email on your behalf. If you want to write to someone, it opens your own Gmail compose window with the address filled in.
One control in the extension clears all stored data from your browser. Removing the extension does the same. You can also revoke MailMop’s access from your Google account settings at any time, independently of us.
Leave your address and we’ll invite you as places open up.
We keep your address to send you one invitation. Nothing else, and we don’t pass it on.
