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

  1. Your campaign will auto-pause at 2% bounce rate
  2. Review bounced leads in the Leads page
  3. Remove or update invalid addresses
  4. 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:

  1. Go to Settings > Email
  2. Verify your @leadclaw.io address is configured correctly
  3. If you recently changed your email prefix, wait a few minutes for propagation
  4. 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
