Workspace admins control SPF, DKIM, and DMARC from the Admin console, and inbound policy from the Gmail spam settings.
What lead email verification is#
Lead verification confirms that a prospect's address exists and accepts mail before it enters a sequence, using syntax checks, MX lookups, SMTP probing, and catch-all detection. Enrichment adds firmographic and role data used for personalization.
Why it matters#
Bounce rate is the fastest way to burn an outbound domain. Unverified purchased lists routinely bounce 10 to 30 percent.
Setting up lead email verification for Google Workspace#
- Verify every address through an API before it enters a sequence.
- Segregate catch-all domains and send to them at lower volume.
- Refresh verification for any lead older than 90 days.
- Enrich with 3 to 5 data points that drive the opening line.
How Google Workspace reports results#
Open a delivered test message in Google Workspace and view the original or headers. Look for Authentication-Results and any provider-specific verdict headers. Use the provider's sender dashboard for aggregate reputation.
Common mistakes#
- Trusting a vendor's 'verified' label from months ago.
- Treating catch-all as valid.
Frequently asked questions#
What bounce rate is safe for cold email?
Under 2 percent. Above 5 percent, pause and re-verify the list before continuing.
Does Google Workspace require lead email verification?
Workspace admins control SPF, DKIM, and DMARC from the Admin console, and inbound policy from the Gmail spam settings. Treat lead email verification as required for any meaningful volume.
