Email Delivery Issues
3 min readUpdated 2026-04-12
High Bounce Rate
If your campaign shows a bounce rate above 2%:
Why It Happens
- Lead email addresses changed after verification
- Company mail servers are temporarily down
- Email addresses were valid but the mailbox is full
What to Do
- Your campaign will auto-pause at 2% bounce rate
- Review bounced leads in the Leads page
- Remove or update invalid addresses
- Resume the campaign once you've cleaned the list
Emails Going to Spam
If recipients report your emails as spam:
Prevention
- LeadClaw already enforces SPF, DKIM, and DMARC authentication
- Every email includes a one-click unsubscribe link
- Physical address is included in every footer
- Email content is checked for spam trigger words
If It Happens
- Your campaign auto-pauses at 0.1% complaint rate
- Review your email content for aggressive language
- Ensure your value proposition is relevant to the audience
- Consider narrowing your target audience
Email Configuration
If your agent can't send emails:
- Go to Settings > Email
- Verify your @leadclaw.io address is configured correctly
- If you recently changed your email prefix, wait a few minutes for propagation
- If issues persist, submit a help ticket
Slow Email Delivery
During the 5-day warmup period, email volume starts low and ramps up daily to your plan's full limit. Starting volume depends on your plan (Free: 2/day, Pro: 5/day, Ultra: 10/day). This is normal and protects your sender reputation. Volume reaches full capacity after day 5.
Still Having Issues?
If you've tried the steps above and emails still aren't delivering, submit a help ticket with:
- Your campaign name and current bounce/complaint rate
- Your @leadclaw.io email address
- Any error messages from the Activity Feed
