Connect Google Ads customer match to MailNesto Staging
Sync segments to Google Ads for search, YouTube and Gmail campaigns.
Google Ads customer match and MailNesto Staging, together
Customer Match lets Google Ads show ads to, or keep them away from, people already on your list across Search, YouTube and Gmail. This connection keeps a Customer Match list in sync with a list or segment in MailNesto Staging and refreshes it every day.
Emails are hashed with SHA-256 before they leave MailNesto Staging, only subscribed and unsuppressed contacts are included, and each sync uploads only what changed: new people added, people who left removed.
What moves between Google Ads customer match and MailNesto Staging
Hashed emails of subscribed contacts in the chosen list or segment, uploaded as a first-party customer list that MailNesto Staging creates on the first sync.
Unsubscribes, suppressions and people who no longer match the segment are removed at the next sync.
Uploads mark ad user data and ad personalisation consent as granted, so make sure the people you sync agreed to be marketed to.

Questions about the Google Ads customer match integration
What does MailNesto Staging need from Google?
A customer ID, developer token, OAuth client ID and secret, and a refresh token. All are checked with a harmless read before the account is saved, and secrets are stored encrypted.
Can I use a manager (MCC) account?
Yes. Enter the manager account ID along with the customer ID of the account that runs the ads.
How quickly do changes reach Google Ads?
MailNesto Staging uploads changes daily or when you click “Sync now”. Google then processes the upload on its side, which can take a while.
Can I send audiences to other ad platforms?
Download a hashed CSV from the Ad audiences tab and upload it to any platform that accepts SHA-256 hashed emails.
