Google Workspace Blocked or Suspended Your Account for Cold Email: What to Do

When Google Workspace blocks sending during a cold email campaign, it is either a temporary sending limit, which usually lifts within 24 hours, or an account suspension, which needs your Workspace admin to review and appeal. Either way, the usual triggers are too much volume too fast, a high bounce rate and spam complaints, so the fix is to verify the list, cut volume and warm back up.

First, work out which problem you have

What you see	Likely cause	How long it lasts
Error saying you reached a limit for sending mail	Daily sending limit for the user	Google says up to 24 hours
Messages bounce back with a rate or quota error	Per-user or per-recipient limits	Usually until the next day
User shows as suspended in the Admin console	Google flagged the user for suspected abuse	Until the admin acts
Whole organisation flagged or billing account issue	Account-level review	Until resolved with Google

Google publishes the limits in its Workspace admin help, including 2,000 messages per user per day, with lower limits on trial accounts. Our Gmail sending limits guide breaks these down.

If it is a temporary sending limit

1. Stop the campaign in your sequencer. Do not let it retry while the limit is active.
2. Wait it out. Let the full block pass before sending anything else from that user.
3. Check what you actually sent. Count total messages, including follow-ups and internal mail. Sequencers can send more than you think when steps pile up.
4. Lower the daily cap. Cold email volume per inbox should be far below Google's ceiling. How many cold emails per inbox explains why the safe number is much lower than the limit.

If the user or account is suspended

1. Have the Workspace admin check the Admin console. The user's page shows whether they are suspended and usually why.
2. Follow Google's appeal or restore steps as shown there. Be accurate about what you were sending.
3. Do not move the same campaign to a new account. Creating fresh users to keep mailing the same list repeats the problem and puts the rest of your domain at risk.
4. Fix the cause before you send again, using the steps below.

Find the cause

Look at the campaign data from the days before the block:

• Bounce rate. Export bounces from your sequencer and read them. "User unknown" or "no such user" means the list had dead addresses. Paste a few into the bounce message analyzer.
• Volume jump. Did a new inbox go from zero to hundreds of emails a day? New inboxes need warming up; see the warm-up schedule.
• Complaints. People marking you as spam is the fastest way to lose a sending reputation. Check Google Postmaster Tools if your domain sends enough to show data.
• Authentication. Missing SPF, DKIM or DMARC makes everything worse. Run the bulk email authentication checker on your sending domain.

Clean the list before sending again

If bounces played a part, verify everything still queued before you resume:

1. Export the remaining leads from your sequencer as CSV.
2. Remove everyone who already bounced and add them to your suppression list.
3. Verify the rest. Keep valid addresses; hold back catch-all and unknown; drop invalid.
4. Re-import only the valid segment to start.

Our guide on what to do after a high bounce rate covers the first 24 hours in more detail.

Restart slowly

After a block, restart lower than you were before:

Day	Suggested pace
First few days back	A small fraction of your previous daily volume per inbox
Following week	Increase gradually if bounces and complaints stay low
After that	Hold a steady daily volume well under provider limits

Spread volume across more inboxes and domains instead of pushing one user hard. The email sending limits calculator helps plan inbox counts for a target volume.

Prevent it next time

• Verify every new lead list before it enters a sequence.
• Re-verify contacts older than about three months.
• Keep catch-all addresses in a separate, low-volume step.
• Set a bounce pause rule in your sequencer that triggers well before trouble; see when to pause a campaign for bounces.

Keep your primary domain out of it

Running cold outreach from the same Workspace domain your company uses for customers puts everything at risk. Use separate, warmed domains and mailboxes for outreach so a block affects only those.

Verify before you resume

Upload the leads still waiting in your sequence on the verify page and send only the valid ones first. You get 100 free email checks when you sign in with Google, no card.
