How to Fix “Messages you sent couldn’t be delivered” & “A contact is getting too much mail” on LGM La Growth Machine
May 21, 2025
When your deliverability tanks overnight
You wake up to campaign reports showing dozens of bounced emails. The errors read “Messages you sent couldn’t be delivered” or “A contact is getting too much mail.” Your carefully crafted sequence grinds to a halt—bounces erode your sender reputation and stall your pipeline.
What’s really happening?
LaGrowthMachine surfaces two common bounce scenarios:
Invalid or inactive addresses – “Messages you sent couldn’t be delivered” means the mailbox doesn’t exist or is disabled.
Volume throttling by recipient servers – “A contact is getting too much mail” shows you’ve sent multiple messages too quickly to the same inbox, triggering server-side limits.
Both errors force LGM to pause those sends. Without action, your campaign remains stalled and prospects go silent.
1) Quick-fix: get your campaign back on track
Clean your list
Upload your CSV to an email verifier (ex: NeverBounce, ZeroBounce). Remove all invalid addresses.
Space out follow‑ups
In your LGM sequence, add longer delays between steps (48–72 hours) to avoid hitting recipient server limits.
Deduplicate contacts
Ensure no single address appears in multiple campaigns or multiple steps; use a unique identifier column in your import.
After these fixes, resume your campaign—the errors will disappear and emails will flow normally.
2) Additional best practices
Verify before import: build a habit of pre-validating fresh lists to catch bad addresses early.
Monitor bounce rates: set a threshold (e.g., 2%) to pause and review if exceeded.
Customize sending domains: use authenticated sending domains and proper SPF/DKIM for better reputation.
Implementing these steps keeps your campaigns healthy and your sender score high.
